The Dream Chaser is to be of largely composite design. Composite design allows a rocket to have SSTO performance if it is of sufficient size.Anyone know if that mass of 9,000 kg is the dry mass or gross mass of the Dream Chaser, meaning containing propellant? If it is the dry mass as I'm assuming it is, then filling the entire internal volume with dense, hydrocarbon, propellant would allow you to get a high Mach suborbital vehicle. And scaling it up twice would allow you to get a fully orbital vehicle as is the case with the X-37B.\n\nThis page has some dimensions of the HL-20:HL-20 Spaceplane Simulation.http:\/\/www.aerorocket.com\/AeroWindTunnel\/IntroToAeroWindTunnel.htmlWe can calculate the volume of some cross-sectional slices from the x,y, and z dimensions given along the length of the vehicle. Adding these together I estimate an internal volume of 46 m^3.However, there is a raised central portion where the passenger compartment will be that tends to cause an overestimate of the volume. On the other hand the surface is convex that tends to cause an under estimate of the volume using the flat cross-sectional slices. So I'll take the volume as the 46 m^3. The density of kerolox is about 1,000 kg\/m^3, so we have about 46,000 kg propellant.The Dream Chaser version has a dry mass of 9,000 kg using hybrid engine(s). We want to swap out these for high efficiency liquid fueled engines. To estimate the mass of the hybrid(s) used on the Dream Chaser, we'll use the information on the SpaceShipOne hybrid engine:SpaceDev Hybrid.http:\/\/web.archive.org\/web\/20080602055644\/http:\/\/www.astronautix.com\/engines\/spaybrid.htmThe mass is estimated as 300 kg. The dry mass of the Dream Chaser is about 9 times that of the SpaceShipOne, so we'll estimate its engines mass as 9 times higher at 2,700 kg. So the mass of the Dream Chaser with the hybrids removed will be 6,300 kg.The total mass of the engine less vehicle is now 46,000 + 6,300 kg = 52,300 kg. We need tanks to hold the propellant mass. The mass of kerolox propellant tanks is typically about 1\/100th that of the propellant. However, with composites we can reduce that to about half that. Call the extra tankage mass 300 kg. This brings the total mass to 52,600 kg.We need kerosene engines to loft this mass. The engine I suggest using is the RD-0242-HC [1]. This is a kerosene fueled version of a hypergolic engine. There have been cases where hydrocarbon versions were derived from hypergolic fueled engines so this should be doable [2].What is the performance we can expect from this engine as hydrocarbon fueled? From the high chamber pressure we can conclude this is a high performance engine. Such Russian engines with vacuum optimized nozzles have gotten in the range of 360 s vacuum Isp. This engine though is listed on the Astronautix site as only having an Isp of 312 s. However, this was for its use as a first stage engine, so this is undoubtedly for a version with a nozzle of intermediate length to be used both at sea level and vacuum. As a point of comparison the Merlin 1C [3] engine used for first stages has a vacuum Isp of 304 s. But the vacuum optimized version which only has a longer nozzle has a vacuum Isp of 342 s.I've also been informed by email that simulations of the RD-0242-HC engine using the engine performance program Propep [4] gave it an Isp in the 370's with a vacuum optimized nozzle. Therefore using altitude compensation I'll take the vacuum Isp as 360 s. For the sea level Isp I'll take the Isp as the 331 s sea level Isp of other high performance Russian engines optimized for sea level use, this time coming though from using altitude compensation.The increased Isp gives it an increased thrust amounting to about 29,800 lbs at sea level, and 32,400 lbs. in vacuum.The 52,600 kg mass of the engine-less vehicle is 115,720 lbs. We'll need five of the engines to lift off and have sufficient T\/W ratio to not incur too great a gravity loss. At an engine mass of 120 kg, this gives the vehicle a gross mass of 53,200 kg and a dry mass of 7,200 kg.For the trajectory averaged Isp use the estimate of 338.3 s for high performance kerosene engines using altitude compensation of Dr. Bruce Dunn in his report [5]. Then our delta-V will be 338.3*9.8ln(53,200\/7,200) = 6,630 m\/s, around Mach 20.Then as with the X-37B scaling up a high Mach capable suborbital craft by a factor of 2 will result in a fully orbit capable craft.The payload could be carried in a cannister above the vehicle. Or you could have a small crew capsule within it so as not to take up to much volume from the propellant.

And moreover if they are scaled up by a factor of 2, then the larger versions become fully orbital vehicles.This is also true of the X-34 and SpaceShipOne: they become high Mach suborbital, as a single stage, when switched to high efficiency engines.

Terraform Mars.Orbiter Martian Terraforming Project (OMTP)Here is a \"crappy\" timetable (any ideas or suggestions are welcome)1. Detonate high-yield conventional bombs on the Martian poles to start the melting process. (I'm not using nuclear because of the radiation)1b.Begin the construction of a Martian monitoring system with satellites and a space station to monitor the process.1c. Divide the Martian surface into quadrants and send over algae (a certain amount at each quadrant) to start the Oxygen build up. (This can be done simultaneously with the bombs and the monitoring system. We can start from the equator and work our way up and down.)2. (just an idea) A 10 MT (or less?) explosion inside the crater of Mount Olympus could wake up that sleeping giant, no?All that CO2 that would be realised from the volcano would be precious for the algae. (unless the explosion blocks the sunlight, which is bad.)Also start making Bases on Mars3.Once enough oxygen exists in the atmosphere: Switch to a Mars 1.5 scenario where enough oxygen in the atmosphere exists to allow plants to live. (different atmospheric parameters for Mars through a config file. See Mars fist steps or the Blue Mars addon)Send plants (a certain amount at each quadrant) to speed up the process.4.In a similar way that the GDIMiner addon works, build super-drills (with \"local\" material) to drill as close as possible to the Martian core and detonate nuclear bombs to \"recandle\" Mars' magnetic field. (Because all that \"atmosphere build-up\" process would just go to waste in a few years -or less- without a magnetic field to shield us from the Sun.)5. Finally, Mars with an atmosphere similar to Earth's and a magnetic field to keep the radiation out. (switching to a Mars 2.0 config file). Colonization is possible.

How much do your altitude compensating engines and their associated thrust structure weigh in comparison to the existing Merlins?Its easy to make a first order estimate and say that something should be possible. Making it actually work is much much harder.That and the assertion that the F9 first stage would be a more efficient launch vehicle than a complete F9 sounds suspiciously like homeopathic rocketry.\n\nJohn Schilling is not likely to reveal the calculations that go into his simulator as it is proprietary. I have suggested to him that he might allow users to input also the sea level thrust and Isp to get more accurate estimates, but he chose not to change his calculator.To see how efficient an SSTO can be, youhaveto use altitude compensation. I was surprised myself how high the payload got for the F9 v1.1 when you assume the first stage engines got the same vacuum Isp as the Merlin Vacuum. But the point is methods of altitude compensation that can work have been known for decades.What would be needed is for these altitude compensating additions to the engines be lightweight.

The F\/A-18 pulls out of each dive at 5,000 feet (about 1,500 meters. Data collected by these flights will be used to finesse the Mars landing radar software, to help ensure that it is calibrated as accurately as possible.The testing is a collaboration of NASA's Dryden Flight Research Center, Edwards, Calif., with NASA's Jet Propulsion Laboratory, Pasadena, Calif. Earlier tests, with a helicopter carrying the test radar, simulated the lower-altitude portion of the spacecraft's descent to the surface of Mars. For more information about the F\/A-18 tests, seehttp:\/\/www.nasa.gov\/topics\/solarsystem\/features\/F-18_flying_msl_radar.html.The Mars Science Laboratory mission's rover, named Curiosity, will be shipped this month from JPL to NASA's Kennedy Space Center in Florida to be readied for launch between Nov. 25 and Dec. 18, 2011. The spacecraft will arrive at Mars in August 2012. After Curiosity lands on Mars, researchers will use the rover's 10 science instruments during the following two years to investigate whether the landing area has ever offered environmental conditions favorable for microbial life.{...}Full article at NASAFull article at NASA Dryden", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.441784832Z", "author": "Urwumpe", "date": "2010-04-30T13:23:14+0100", "id": "ccea85bca35385dae09d71e27fbc6a51", "post_id": "post-219832", "text": "The good thing is, that the big differences between AMD and Intel are gone now.

Clarke's vision of 2001.Space Travel: The Path to Human Immortality?Space exploration might just be the key to human beings surviving mass genocide, ecocide or omnicide.July 24, 2009On December 31st, 1999, National Public Radio interviewed the futurist and science fiction genius Arthur C. Clarke. Since the author had forecast so many of the 20th Century's most fundamental developments, the NPR correspondent asked Clarke if anything had happened in the preceding 100 years that he never could have anticipated. \"Yes, absolutely,\" Clarke replied, without a moment's hesitation. \"The one thing I never would have expected is that, after centuries of wonder and imagination and aspiration, we would have gone to the moon ... and then stopped.\"http:\/\/www.alternet.org\/news\/141518\/space_travel:_the_path_to_human_immortality\/I remember thinking when I first saw 2001 as a teenager and could appreciate it more, I thought it was way too optimistic. We could never have huge rotating space stations and passenger flights to orbit and Moon bases and nuclear-powered interplanetary ships by then.That's what I thought and probably most people familiar with the space program thought that. And I think I recall Clarke saying once that the year 2001 was selected as more a rhetorical, artistic flourish rather than being a prediction, 2001 being the year of the turn of the millennium (no, it was NOT in the year 2000.)However, I've now come to the conclusion those could indeed have been possible by 2001. I don't mean the alien monolith or the intelligent computer, but the spaceflights shown in the film.It all comes down to SSTO's. As I argued above these could have led and WILL lead to the price to orbit coming down to the $100 per kilo range. The required lightweight stages existed since the 60's and 70's for kerosene with the Atlas and Delta stages, and for hydrogen with the Saturn V upper stages. And the high efficiency engines from sea level to vacuum have existed since the 70's with the NK-33 for kerosene, and with the SSME for hydrogen.The kerosene SSTO's could be smaller and cheaper and would make possible small orbital craft in the price range of business jets, at a few tens of millions of dollars. These would be able to carry a few number of passengers\/crew, say of the size of the Dragon capsule. But in analogy with history of aircraft these would soon be followed by large passenger craft.However, the NK-33 was of Russian design, while the required lightweight stages were of American design. But the 70's was the time of detente, with the Apollo-Soyuz mission. With both sides realizing that collaboration would lead to routine passenger spaceflight, it is conceivable that they could have come together to make possible commercial spaceflight.There is also the fact that for the hydrogen fueled SSTO's, the Americans had both the required lightweight stages and high efficiency engines, though these SSTO's would have been larger and more expensive. So it would have been advantageous for the Russians to share their engine if the American's shared their lightweight stages.For the space station, many have soured on the idea because of the ISS with the huge cost overruns. But Bigelow is planning on \"space hotels\" derived from NASA's [ame=\"http:\/\/en.wikipedia.org\/wiki\/TransHab\"]Transhab[\/ame] concept. These provide large living space at lightweight. At $100 per kilo launch costs we could form large space stations from the Transhabs linked together in modular fashion, financed purely from the tourism interests. Remember the low price to orbit allows many average citizens to pay for the cost to LEO.The Transhab was developed in the late 90's so it might be questionable that the space station could be built from them by 2001. But remember in the film the space station was in the process of being built. Also, with large numbers of passengers traveling to space it seems likely that inflatable modules would have been thought of earlier to house the large number of tourists who might want a longer stay.For the extensive Moon base, judging from the Apollo missions it might be thought any flight to the Moon would be hugely expensive. However, Robert Heinlein once said: once you get to LEO you're half way to anywhere in the Solar System. This is due to the delta-V requirements for getting out of the Earth's gravitational compared to reaching escape velocity.It is important to note then SSTO's have the capability once refueled in orbit to travel to the Moon, land, and return to Earth on that one fuel load. Because of this there would be a large market for passenger service to the Moon as well. So there would be a commercial justification forBigelow's Transhab motels to also be transported to the Moon.Initially the propellant for the fuel depots would have to be lofted from Earth. But we recently found there was water in thepermanently shadowed craters on the Moon. Use of this for propellant would reduce the cost to make the flights from LEO to the Moon since the delta-V needed to bring the propellant to LEO from the lunar surface is so much less than that needed to bring it from the Earth's surface to LEO.This lunar derived propellant could also be placed in depots in lunar orbit and at the Lagrange points. This would make easier flights to the asteroids and the planets. The flights to the asteroids would be especially important for commercial purposes because it is estimated even a small sized asteroid could havetrillions of dollars worth of valuable minerals. The availability of such resources would make it financially profitable to develop large bases on the Moon for the sake of the propellant.Another possible resource was recentlydiscovered on the Moon: uranium. Though further analysis showed the surface abundance to be much less than in Earth mines, it may be that there are localized concentrations just as there are on Earth. Indeed this appears to be the case withsome heavy metals such as silver and possibly goldthat appear to be concentrated in some polar craters on the Moon.So even if the uranium is not as abundant as in Earth mines, it may be sufficient to be used for nuclear-powered spacecraft. Then we wouldn't have the problem of large amounts of nuclear material being lofted on rockets on Earth. The physics and engineering of [ame=\"http:\/\/en.wikipedia.org\/wiki\/NERVA\"]nuclear powered rockets have been understood since the 60's[\/ame]. The main impediment has been the opposition to launching large amounts of radioactive material from Earth into orbit above Earth. Then we very well could have had nuclear-powered spacecraft launching from the Moon for interplanetary missions, especially when you consider the financial incentive provided by minerals in the asteroids of the asteroid belt.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.65111552Z", "author": "gattispilot", "date": "2010-09-03T13:25:26+0100", "id": "8578d16281529bc96bfbfdb5a89d097b", "post_id": "post-253083", "text": "I am using anim8or.Any suggestions on making a crater?

A special wider \/ shorter core could be implemented (for a single RD-180, it is shown in the evolution picture) but the main plan would be really to field a new common core, with two RD-180: this provides engine out for crewed vehicles for the first stage (and upper stage could have that engine out feature too) and keeps using a known hardware component (the Rd-180) for such new cores (instead of requiring extra propulsion considerations).Of course that some variation of a single RD-17X could do the same job (at least in terms of performance) but that would mean yet a new contract, etc: under current reality, there are already many RD-180 in storage and\/or ordered and there was also some information exchanged that, in theory, could allow the \u2018domestic\u2019 (United States of America) production of the RD-180 (such domestic production capability seems to have been originally a requirement for all EELV but only Delta met that goal, with the development of the RS-68)\u2026 Although it is also true that there are several opinions about the true verification of such capability for the RD-180 (would the resulting RD-180 be really equal to the original version in terms of mass and performance? and how about the price?)\u2026 There are also opinions that mention that would probably be better to have a fresh start, with a more powerful engine \u2013 with thrust then at ~F1-A or RD-17X levels - as long as (and this is kind of important) there is money to pay for such 100% new development (instead of continuing to pay or trying to replicate the RD-180).Regarding bringing such plans into Orbiter:I\u2019m planning to implement some of the AtlasV Evolution stuff into an eventual future release (whenever that happens) of NASA VSE SC addon although will probably use the older ~5.5m diameter plans (current real life iterations assume the cores \/ upper stages at ~5m diameter). In fact, have played a little with that but will probably stop at the single core of Phase2 (and leave heavier lift for a SDLV with a later kerolox booster upgrade).

Boeing is well aware of the weight savings that can be accomplished using composites because of their experience with the Dreamliner 787 and the X-37B.It's not a coincidence that Boeing is the one investigating this.\n\nDon't let me get started on this one. Well, too late.The Dreamliner is actually heavier when empty than the old Boeing 767 it is meant to replace. It just carries a tiny bit more fuel per dry mass, but when looking at the engineering inside an aircraft, this isn't because there is more volume for fuel in the Dreamliner, but because the Dreamliner has much more effective wings as the obsolete 767.Effective weight-savings by Boeing when using composite structures? extremely little. The A330 of Airbus, that has only a conservative use of composite structures, has almost the same mass properties as the 787, but a slightly shorter range (but Airbus has much longer experience in that field than Boeing, especially since Europe did already do research for civilian use when Boeing left composite structures to military projects with high maintenance requirements)Again: Composite materials are alone no guarantee for lower mass. They can be lighter, no question, especially in places with low dynamic loads, but overall, their impact is very low.Engineering is a science, and every science has its paradoxes, because not everything follows a simple linear model.

STS throttles down to 3Gs for astronaut comfort (the Orbiter Vehicle, at least, is rated for something like 5Gs), and it doesn't seem to have too many problems with gravity losses.\n\nGravity losses are problem in the begining of flight when you have to quickly clear dense parts of atmosphere and gain tangential speed.It isn't a problem for the shuttle (SRBs at lift-off) but for SSTO it will be a problem of efficiency. Remember that ~70% of lift-off thrust of STS is from boosters.My point is that designing an engine for SSTO that will be efficent (high ISP) on 100% throttle and 20% and will provide enough thrust to minimize gravity losses (high thrust) is very difficult.Probably I haven't written that very well.Also I've used ETS as reference because I'm quite familiar with this rocket and it's capabilities:p(over 100 test launches during dev process)T.Neo said:But another issue is, if you throttle down enough, or even shut down an engine(s), you are suddenly finding yourself flying a vehicle with a good deal of parasitic mass onboard...\n\nExactly - throttled down engines work usually below theirs maximum efficiency.PS - I'll try to do the same for umanned boosters\/stages and post results here.---------- Post added at 11:02 PM ---------- Previous post was at 10:56 PM ----------BTW my most with ETS calculations was intended to show that doing numbers for orbiter isn't that hard.

Maybe together with another satellite in that weight class that he will launch for $6000 per kg on a bigger launcher (\"The first one is for free\"). But economically, I doubt he could even get the aluminum for building his rockets for that launch price.\n\nKeep in mind the $100 to $200 per kg number is not arbitrary but is based on estimates by the SpaceX engineers of, for example, their understanding of the reusability of their engines, the most costly part of a rocket. Elon has said the Merlin should be reusable ten's of times.About your example I think you meant $600,000 to $1,200,000 for that 6,000 kg satellite. But the low cost reusable vehicle does not yet exist. However, I think he would accept that paymentnowif that launch only had to be within the next 10 to 20 years.:)Speaking of economic \"bets\". Consider this scenario. There have been many cases of people who got in early on an initial public offering and made out big when those companies became successful, such as with Apple, Google, etc.Let's suppose thatifSpaceX succeeded they would patent their reusable $100 per kg design so that no one else could use it or would have to pay license fees to SpaceX to use it, and no other company got in on the reusability paradigm to be able to field their own design for another say 5 years while SpaceX is fielding theirs. But let's say we still don't know whether or not SpaceX will succeed. We just know they said they'll patent their design when they get it and since no company is working on it, it would take a few years to catch up.Under those conditions, clearlyifthey succeeded they would get a huge market share. Now let's say tomorrow SpaceX offered an IPO.Would you buy their stock? Note this is asking a question on how you view the likelihood of them succeeding at this idea. I would, because I consider it likely they will succeed. Also, the other orbital launch companies have shown no dedication to achieving it.

So an altitude-compensating engine is a very good idea if you're trying to build an SSTO... so long as the added complexity doesn't cost more than you gain.If I remember correctly, the shuttle's SRBs make up about half the launch mass and that's all burned to get the shuttle above most of the atmosphere.

Every component has a bath tub plot of its own. And there are quite many components in the system, that are reused even in expendable rockets: The ground segment.Then, you also have a background noise of failures in your operations. A procedure can be failure prone, without appearing like it initially. You can get more failures in a part initially appearing safe, when you get higher flight rates.Also, it can become harder to produce components, when their parts become obsolete - what happens quickly today. Then you will get again an increased number of failures, even if your parts are produced new for every flight - this usually happens at the end of the life time of a ELV again.Usually, you freeze the requirements of the new product generation not before your current one has entered the low and stable part of the bath tub. Then you know enough about the hardware and get ideas about the wetware. When the new product is entering test operations, you have enough experience in the wetware from the previous product to improve the operations.

Most of us simply doubt that:- You can get the dry mass low enough for building a real expendable one with expendable low-performance engines or- You can get the engine performance high enough to build a real reusable one with reuseable high-performance engines.That is the part that RGClark simply ignores. The logic in his argumentation is pretty much like these two alternative paths:Rocket equation says a certain SSTO configuration is possible \u25ba Something magical happens here \u25ba Launch costs are down to $100 per kgOr:Rocket equation says a certain SSTO configuration is possible \u25ba Launch costs are down to $100 per kg because Elon Musk says so.If I would give Elon Musk the paperwork for a 6000 kg satellite and $60,000 for launching it, do you think he will take the contract and launch it for that price? Maybe together with another satellite in that weight class that he will launch for $6000 per kg on a bigger launcher (\"The first one is for free\"). But economically, I doubt he could even get the aluminum for building his rockets for that launch price.Contrary to paper rockets, real rockets are made of real materials, that cost money and need employees and tools that also cost money. all that money goes into the launch costs, together with the R&D effort to get from paper rockets to blueprints. Plus the money for the 200-300 employees that you need for managing your company and keeping contact to your customers and suppliers (You can Kanban rocket production, but you can't rely on standardized supplier networks like car companies already have).$1000 per kg would already be a major achievement in that economic situation. You would need a pretty cheap launcher with lots of payload, so the overhead does not harm that much.Just for some fun, I know that the argumentation is really weak and more absurd than realistic economics: if you would try to send your payload with the needed SSTO rocket (An idea less than 1% payload mass fraction) from USA to Europe the cheapest way (in small parts or rolls of sheet metal, container ship, assuming $2000 per TEU), you would already be close to fail if you want to do that with $100 per kg payload (You could transport a scout rocket and its tiny payload actually with that rate, but without any transport tools, like making sure the rocket survives rough seas)Of course it makes no sense (why should you do that?), but it shows well how cheap $100 per kg for a space transportation service actually is in the real world.RGClark has done nothing that you don't already get presented in your first semester of aerospace engineering - The case of a SSTO based on the rocket equation and how light it would have to be for having positive payload mass fraction with realistic engines.You are right, that alone is no reason for 17 pages of arguments.What annoys me is his Velcro Rocket attitude (Without even bothering using Velcro), of taking existing stages and then do some obscure modifications to them to say: See, it can be done. It is still cheap paper rocketry, but presented like other engineers are just ideologically disoriented, SSTOs censored from engineering or incompetent.It is like doing just the first 2 hours feasibility study for a new rocket, that will eventually take 5,000,000 man hours to develop (about $1,000,000,000 development costs, that is actually cheap), and claim you did all the important work there.Maybe this is a bit negative. But the optimistic interpretation of the situation would be: Such launch costs can only be achieved with a revolution in rocketry and in the economics on the ground.", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.521577728Z", "author": "TheMineGamer32", "date": "2014-11-19T22:22:04+0000", "id": "cb4d0698cb26747750b26ff53e5294ec", "post_id": "post-252784", "text": "Oh man, I need more DGIV training and less addon repairing.", "thread_id": 16326 }, { "@timestamp": "2023-09-14T07:13:05.661697792Z", "author": "Pablo49", "date": "2010-05-04T05:17:17+0100", "id": "591c762646494da2569e5731a455a848", "post_id": "post-220619", "text": "Could we use something like Vessel Stack to make the interplanetary stack\/MSS?

The Air Force favors this since this may also be used to tow inactive satellites out the way of operable satellites, thus reducing the problem of space debris:Article:World's First Space Gas Station for Satellites to Launch in 2015.by Clara Moskowitz, SPACE.com Senior WriterDate: 15 March 2011 Time: 06:03 PM ET\"Until now, satellites orbiting around Earth have been limited by how much fuel they carry onboard. Once those tanks run dry, the satellites die, sometimes languishing in space as uncontrollable debris that then poses the risk of colliding with other spacecraft.\"The new plan offers the potential not just to extend the lives of working satellites, but to help combat the growing space junk problem. The satellite, called the Space Infrastructure Servicing (SIS) vehicle, is designed not just to transfer more fuel into existing satellites, but to inspect, tow, reposition and make minor repairs to them.\"In addition to its tank of fuel, the refueling satellite will carry a robotic arm that can be used to grab onto satellites and tug at stuck solar array panels, for example, or attempt other minor fixes to broken parts.'This is a first-time-ever, huge, huge, huge event,' said Andrew Palowitch, director of the Space Protection Program, a joint project of U.S. Air Force Space Command and the National Reconnaissance Office, speaking at a National Research Council workshop on orbital debrislast week.\"Palowitch stressed that the ability to tow or refuel dead satellites in order to steer them out of the way would have a big impact on the growing problem of dangerous space debris clogging the crowded corridors of Earth orbit. [Worst Space Debris Events of All Time]'In the context of debris removal, this is the absolute best and absolute most fantastic new venture for the entire space community,' he said.\"The refueling satellite will be able to move dead spacecraft to what's called the 'graveyard orbit,' where they are high enough that they should not pose a risk to working satellites, or maneuver them low enough that they break apart in Earth's atmosphere.\"http:\/\/www.space.com\/11135-satellite-refueling-mission-space-debris.htmlThen the Air Force recognizes the usefulness of reusable vehicles, when they are in-space. However, the importance of reusable SSTO's is that they could also return these satellites to Earth for repair or salvage.Remember the old science fiction series Salvage 1:Salvage 1.[ame=\"http:\/\/en.wikipedia.org\/wiki\/Salvage_1\"]Salvage 1 - Wikipedia, the free encyclopedia[\/ame]The theme of the show was a small \"home made\" spaceship was used to return space junk to Earth. I used to think the show was quite implausible because the spaceship went all the way to the Moon and everybody \"knows\" it takes huge Saturn V sized rockets to do that.However, as I discussed in post#136small, low cost SSTO's are indeed possible. And it is a known fact that if you have refueling in LEO then an SSTO can go all the way to the Moon, land, take off, and return to Earth on that one single refueling. So in fact the idea of salvaging spacecraft or satellites from the Moon and\/or from GEO is feasible with SSTO's and on-orbit propellant depots.Then this provides another financial benefit for SSTO's for private developers and for the Air Force. Imagine being able to retrieve satellites, the largest of which can cost upwards of a billion dollars, for reuse or possibly for sale. This does though raise the question of what would be the salvage laws for space.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.54570368Z", "author": "Moach", "date": "2010-09-02T17:17:00+0100", "id": "3e8853843c2987b50369417c4fd8e637", "post_id": "post-252877", "text": "i got a BSOD on lvl5... that was on my work rig, GeForce9500... :shrug:", "thread_id": 16332 }, { "@timestamp": "2023-09-14T07:13:05.635216128Z", "author": "Pablo49", "date": "2010-05-02T21:20:20+0100", "id": "209db7db9b8558021b8cd70bb8cb240f", "post_id": "post-220561", "text": "I definitely want in on this.I also like Urwumpe's idea for the UMMU.:)", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:05.6135552Z", "author": "Izack", "date": "2010-05-07T00:43:49+0100", "id": "2ab705e82883c43f0e50762ab9d0009b", "post_id": "post-220727", "text": "Wolfer said:It's the Nerva-2 without it's external tanks.\n\nDerp.:pI should have known that.I'm not sure how we're going to go about constructing an underground base.

A third scoop sample was collected on Oct. 15, or Sol 69, and deposited into the Chemistry and Mineralogy (CheMin) instrument on Oct. 17, or Sol 71.Image credit: NASA\/JPL-Caltech\/MSSS\u200bUnannotated version\u200b|||Wind-Blown Martian Sand\u200bThis pair of images from the Mast Camera on NASA's Curiosity rover shows the upper portion of a wind-blown deposit dubbed \"Rocknest.\" The rover team recently commanded Curiosity to take a scoop of soil from a region located out of frame, below this view. The soil was then analyzed with the Chemistry and Mineralogy instrument, or CheMin.Image credit: NASA\/JPL-Caltech\/MSSS\u200b|The identification of minerals in rocks and soil is crucial for the mission's goal to assess past environmental conditions. Each mineral records the conditions under which it formed. The chemical composition of a rock provides only ambiguous mineralogical information, as in the textbook example of the minerals diamond and graphite, which have the same chemical composition, but strikingly different structures and properties.CheMin uses X-ray diffraction, the standard practice for geologists on Earth using much larger laboratory instruments. This method provides more accurate identifications of minerals than any method previously used on Mars. X-ray diffraction reads minerals' internal structure by recording how their crystals distinctively interact with X-rays. Innovations from Ames led to an X-ray diffraction instrument compact enough to fit inside the rover.These NASA technological advances have resulted in other applications on Earth, including compact and portable X-ray diffraction equipment for oil and gas exploration, analysis of archaeological objects and screening of counterfeit pharmaceuticals, among other uses.\"Our team is elated with these first results from our instrument,\" said Blake. \"They heighten our anticipation for future CheMin analyses in the months and miles ahead for Curiosity.\"The specific sample for CheMin's first analysis was soil Curiosity scooped up at a patch of dust and sand that the team named Rocknest. The sample was processed through a sieve to exclude particles larger than 0.006 inch (150 micrometers), roughly the width of a human hair. The sample has at least two components: dust distributed globally in dust storms and fine sand originating more locally. Unlike conglomerate rocks Curiosity investigated a few weeks ago, which are several billion years old and indicative of flowing water, the soil material CheMin has analyzed is more representative of modern processes on Mars.\"Much of Mars is covered with dust, and we had an incomplete understanding of its mineralogy,\" said David Bish, CheMin co-investigator with Indiana University in Bloomington. \"We now know it is mineralogically similar to basaltic material, with significant amounts of feldspar, pyroxene and olivine, which was not unexpected. Roughly half the soil is non-crystalline material, such as volcanic glass or products from weathering of the glass. \"Bish said, \"So far, the materials Curiosity has analyzed are consistent with our initial ideas of the deposits in Gale Crater recording a transition through time from a wet to dry environment. The ancient rocks, such as the conglomerates, suggest flowing water, while the minerals in the younger soil are consistent with limited interaction with water.\"{...}NASA News Release:RELEASE : 12-383 - NASA Rover's First Soil Studies Help Fingerprint Martian MineralsScience Daily:Mars Like Hawaii?

From a fourth scoopful, samples will be delivered to both CheMin and to the sample analysis at Mars (SAM) instrument, which identifies chemical ingredients.\"We're going to take a close look at the particle size distribution in the soil here to be sure it's what we want,\" said Daniel Limonadi of JPL, lead systems engineer for Curiosity's surface sampling and science system. \"We are being very careful with this first time using the scoop on Mars.\"The rinse-and-discard cycles serve a quality-assurance purpose similar to a common practice in geochemical laboratory analysis on Earth.\"It is standard to run a split of your sample through first and dump it out, to clean out any residue from a previous sample,\" said JPL's Joel Hurowitz, a sampling system scientist on the Curiosity team. \"We want to be sure the first sample we analyze is unambiguously Martian, so we take these steps to remove any residual material from Earth that might be on the walls of our sample handling system.\"Rocknest is the name of the area of soil Curiosity will test and analyze. The rover pulled up to the windblown, sandy and dusty location Oct. 2. The Rocknest patch is about 8 feet by 16 feet (2.5 meters by 5 meters). The area provides plenty of area for scooping several times. Diverse rocks nearby provide targets for investigation with the instruments on Curiosity's mast during the weeks the rover is stationed at Rocknest for this first scooping campaign.Curiosity's motorized, clamshell-shaped scoop is 1.8 inches (4.5 centimeters) wide, 2.8 inches (7 centimeters) long, and can sample to a depth of about 1.4 inches (3.5 centimeters). It is part of the collection and handling Martian rock analysis (CHIMRA) device on a turret of tools at the end of the rover's arm. CHIMRA also includes a series of chambers and labyrinths for sorting, sieving and portioning samples collected by the scoop or by the arm's percussive drill.Following the work at Rocknest, the rover team plans to drive Curiosity about 100 yards (about 100 meters) eastward into the Glenelg area and select a rock as the first target for use of its drill.{...}NASA News Release:RELEASE : 12-348 - NASA Mars Curiosity Rover Prepares to Study Martian SoilSpaceRef:Curiosity Prepares to Study Martian SoilSPACE.com:Curiosity Rover to Scoop Up 1st Mars Samples This WeekendThe Planetary Society Blog:Curiosity Update, sol 57: Digging in at RocknestCBS News Space:Curiosity gets the scoop on MarsScience Daily:NASA Mars Curiosity Rover Prepares to Study Martian SoilDiscovery News:Mars Rover Ready to Scoop Sand: Big PicUniverse Today:Curiosity Set for 1st Martian Scooping at \u2018Rocknest\u2019 Ripple", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.48205824Z", "author": "Pilot7893", "date": "2010-04-30T13:16:50+0100", "id": "541bede28e60176f77145c797ae38fd7", "post_id": "post-219968", "text": "Because kids these days don't take video games seriously enough already.*points at MW2 and CS:S*", "thread_id": 14067 }, { "@timestamp": "2023-09-14T07:13:05.52857728Z", "author": "IronRain", "date": "2010-05-02T20:40:47+0100", "id": "2c6218f8a7ae4bc6a0554cd171035eea", "post_id": "post-220067", "text": "in fact, Soyuz was kind of build to be automated, right?", "thread_id": 14076 }, { "@timestamp": "2023-09-14T07:13:36.130331648Z", "author": "Jarvit\u00e4", "date": "2010-08-29T22:34:17+0100", "id": "ec19ca29917c3ae184fca17674038a48", "post_id": "post-252271", "text": "Just saw this on slashdot a few days ago, a pretty awesome visualisation to be sure.

MAHLI's close-up inspections of Martian rocks and soil will show details so tiny, the calibration target includes reference lines finer than a human hair.

The spacecraft, launched Nov. 26, 2011, will deliver Curiosity to a landing site inside Mars' Gale Crater in August to begin a two-year investigation of whether that area has ever offered an environment favorable for microbial life.The \"hand lens\" in MAHLI's name refers to field geologists' practice of carrying a hand lens for close inspection of rocks they find. When shooting photos in the field, geologists use various calibration methods.\"When a geologist takes pictures of rock outcrops she is studying, she wants an object of known scale in the photographs,\" said MAHLI Principal Investigator Ken Edgett, of Malin Space Science Systems, San Diego. \"If it is a whole cliff face, she'll ask a person to stand in the shot. If it is a view from a meter or so away, she might use a rock hammer. If it is a close-up, as the MAHLI can take, she might pull something small out of her pocket. Like a penny.\"Edgett bought the special penny that's aboard Curiosity with funds from his own pocket. It is a 1909 \"VDB\" cent, from the first year Lincoln pennies were minted, the centennial of Abraham Lincoln's birth, with the VDB initials of the coin's designer - Victor David Brenner -- on the reverse.\"The penny is on the MAHLI calibration target as a tip of the hat to geologists' informal practice of placing a coin or other object of known scale in their photographs. A more formal practice is to use an object with scale marked in millimeters, centimeters or meters,\" Edgett said. \"Of course, this penny can't be moved around and placed in MAHLI images; it stays affixed to the rover.\"The middle of the target offers a marked scale of black bars in a range of labeled sizes. While the scale will not appear in photos MAHLI takes of Martian rocks, knowing the distance from the camera to a rock target will allow scientists to correlate calibration images to each investigation image.Another part of MAHLI's calibration target displays six patches of pigmented silicone as aids for interpreting color and brightness in images. Five of them -- red, green, blue, 40-percent gray and 60-percent gray -- are spares from targets on NASA Mars rovers Spirit and Opportunity. The sixth, with a fluorescent pigment that glows red when exposed to ultraviolet light, allows checking of an ultraviolet light source on MAHLI. The fluorescent material was donated to the MAHLI team by Spectra Systems, Inc., Providence, R.I.A stair-stepped area at the bottom of the target, plus the penny, help with three-dimensional calibration using known surface shapes.Curiosity also carries calibration materials for other science instruments on the rover. \"The importance of calibration is to allow data acquired on Mars to be compared reliably to data acquired on Earth,\" said Mars Science Laboratory Project Scientist John Grotzinger, of the California Institute of Technology, Pasadena.The MAHLI calibration target, with its penny and a miniscule cartoon of a character named \"Joe the Martian,\" serves an additional function: public engagement.\"Everyone in the United States can recognize the penny and immediately know how big it is, and can compare that with the rover hardware and Mars materials in the same image,\" Edgett said. \"The public can watch for changes in the penny over the long term on Mars. Will it change color? Will it corrode? Will it get pitted by windblown sand?\"The Joe the Martian character appeared regularly in a children's science periodical, \"Red Planet Connection,\" when Edgett directed the Mars outreach program at Arizona State University, Tempe, in the 1990s. Joe was created earlier, as part of Edgett's schoolwork when he was 9 years old and NASA's Mars Viking missions, launched in 1975, were inspiring him to dream of becoming a Mars researcher.Edgett said, \"The Joe the Martian on Curiosity really is a 'thank you' from the MAHLI team to the folks who have provided us with the opportunity to study Mars, the U.S. taxpayers. He is also there to encourage children around the world to set goals that will help them achieve their dreams in whatever interests they pursue.\"{...}", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.669161216Z", "author": "Pablo49", "date": "2010-05-05T21:15:29+0100", "id": "db53af2876f2d3855509016b25ab3541", "post_id": "post-220684", "text": "I support the name Pegasus.

You could make the vehicle a good deal smaller if you used something like methane, but you would of course take a performance hit...\n\nStill, it's lift-off mass is in one league with the 747. Despite Hydrogen being the lightest variant. A kerosene based version would be heavier than a A380 - if it could fly and reach orbit at all.T.Neo said:Do you really have to slash your performance by half to get 'more user-friendly hardware'?\n\nApproximately yes, maybe even more. A small drop in ISP means a big change in vehicle mass for the same trajectory.T.Neo said:What is the cutoff point for 'user-friendly'? How user friendly do you have to be? Is it absolutely guaranteed that an SSTO would not be 'user-friendly'?\n\nLets define \"user-friendly\" as such: The pilot\/owner\/whoever can do the preflight and post-flight checks himself, and only needs specialist knowledge for dealing with the big problems. if you permit some additional mass penalty for example, you could make it possible for a skilled technician to swap a turbopump assembly, without you needing to hire a specialist team, like for example if you would need for replacing a turbopump rotor or bearing.Current situation in spaceflight is as such: For everything, you need experts, usually in the price class of engineers. You can already do some small maintenance as IVA and EVA, which is about on the skill level for skilled technicians, but it is impossible to fly without. And the problem is not the staging system, but such mundane things like the engines or the propellant utilization system.Calibrating a IMU isn't that complex, you could do that with adequate accuracy without studying physics. But the subsystem has to be designed for this task.Swapping a LRU or installing new software would be fairly easy, providing automated test equipment isn't a problem. But could you for example replace a damaged heavy-duty valve? Not that easy without the valve helping you.Replacing a worn-out bearing on a engine turbopump is really rocket science - not only do you need to deal with complex pneumatics and extreme accuracies, but you also need to do tasks like being able to balance a turbopump shaft afterwards again to prevent destructive vibrations. A high-performance turbopump runs at 250,000 RPM. If you want to be at least effective, you run at 100,000 RPM. if you want it cheap, but bulky, you use just 50,000 RPM and pay a hefty fuel efficiency price. Even for the 50,000 RPM turbopump, you will need to balance the rotor carefully. At 250,000 RPM, you balance in the range of a few hundred nanogram. Special engineers can do that, with special expensive machines. They cost you a few million per rotor then (alone about 400,000 USD for the wages). And you can't make it automatic. You will always need specialists to make sure the machines are not optimizing the rotor away into tiny chips of metal waste. The local optimum for the balance is not always the global optimum that you want.If a spacecraft owner would need to send his spacecraft to a special company every every flight to check for such expensive problems and do the overhaul because even small checks mean disassembling sensitive parts, it is not user-friendly, the user who paid for it will spend less time with his investment as the technicians to maintain it.Even if you want to just attract major companies, you need a low-cost approach to maintenance. Especially since you will have to assume that you are not alone in the world and your design might be the first, but not the last to appear.

And since it is much lighter than the SSTO for the same payload, it will fly with much cheaper engines anyway. Also the TSTO will be able to use better optimized engines - regardless which technology you use on the SSTO for making the engines less sensible to ambient pressure, the TSTO can also use it for its advantage.And the indigenous modular construction of a TSTO also makes it much cheaper to construct it: The main parts are smaller, while a SSTO has to be pretty monolithic.", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.633330432Z", "author": "Urwumpe", "date": "2010-05-02T20:14:16+0100", "id": "2af43e3e3f945cf0267e7d3701c5d7ad", "post_id": "post-220546", "text": "supersonic said:True, but if we launch every two-three days it's a different story.

Clarke. Since the author had forecast so many of the 20th Century's most fundamental developments, the NPR correspondent asked Clarke if anything had happened in the preceding 100 years that he never could have anticipated. \"Yes, absolutely,\" Clarke replied, without a moment's hesitation. \"The one thing I never would have expected is that, after centuries of wonder and imagination and aspiration, we would have gone to the moon ... and then stopped.\"http:\/\/www.alternet.org\/news\/141518\/space_travel:_the_path_to_human_immortality\/I remember thinking when I first saw 2001 as a teenager and could appreciate it more, I thought it was way too optimistic. We could never have huge rotating space stations and passenger flights to orbit and Moon bases and nuclear-powered interplanetary ships by then.That's what I thought and probably most people familiar with the space program thought that. And I think I recall Clarke saying once that the year 2001 was selected as more a rhetorical, artistic flourish rather than being a prediction, 2001 being the year of the turn of the millennium (no, it was NOT in the year 2000.)However, I've now come to the conclusion those could indeed have been possible by 2001. I don't mean the alien monolith or the intelligent computer, but the spaceflights shown in the film.It all comes down to SSTO's. As I argued above these could have led and WILL lead to the price to orbit coming down to the $100 per kilo range. The required lightweight stages existed since the 60's and 70's for kerosene with the Atlas and Delta stages, and for hydrogen with the Saturn V upper stages. And the high efficiency engines from sea level to vacuum have existed since the 70's with the NK-33 for kerosene, and with the SSME for hydrogen.The kerosene SSTO's could be smaller and cheaper and would make possible small orbital craft in the price range of business jets, at a few tens of millions of dollars. These would be able to carry a few number of passengers\/crew, say of the size of the Dragon capsule. But in analogy with history of aircraft these would soon be followed by large passenger craft.However, the NK-33 was of Russian design, while the required lightweight stages were of American design. But the 70's was the time of detente, with the Apollo-Soyuz mission. With both sides realizing that collaboration would lead to routine passenger spaceflight, it is conceivable that they could have come together to make possible commercial spaceflight.There is also the fact that for the hydrogen fueled SSTO's, the Americans had both the required lightweight stages and high efficiency engines, though these SSTO's would have been larger and more expensive. So it would have been advantageous for the Russians to share their engine if the American's shared their lightweight stages.For the space station, many have soured on the idea because of the ISS with the huge cost overruns. But Bigelow is planning on \"space hotels\" derived from NASA'sTranshabconcept. These provide large living space at lightweight. At $100 per kilo launch costs we could form large space stations from the Transhabs linked together in modular fashion, financed purely from the tourism interests. Remember the low price to orbit allows many average citizens to pay for the cost to LEO.The Transhab was developed in the late 90's so it might be questionable that the space station could be built from them by 2001. But remember in the film the space station was in the process of being built. Also, with large numbers of passengers traveling to space it seems likely that inflatable modules would have been thought of earlier to house the large number of tourists who might want a longer stay.For the extensive Moon base, judging from the Apollo missions it might be thought any flight to the Moon would be hugely expensive. However, Robert Heinlein once said: once you get to LEO you're half way to anywhere in the Solar System. This is due to the delta-V requirements for getting out of the Earth's gravitational compared to reaching escape velocity.It is important to note then SSTO's have the capability once refueled in orbit to travel to the Moon, land, and return to Earth on that one fuel load. Because of this there would be a large market for passenger service to the Moon as well. So there would be a commercial justification forBigelow's Transhab motels to also be transported to the Moon.Initially the propellant for the fuel depots would have to be lofted from Earth. But we recently found there was water in thepermanently shadowed craters on the Moon. Use of this for propellant would reduce the cost to make the flights from LEO to the Moon since the delta-V needed to bring the propellant to LEO from the lunar surface is so much less than that needed to bring it from the Earth's surface to LEO.This lunar derived propellant could also be placed in depots in lunar orbit and at the Lagrange points. This would make easier flights to the asteroids and the planets. The flights to the asteroids would be especially important for commercial purposes because it is estimated even a small sized asteroid could havetrillions of dollars worth of valuable minerals. The availability of such resources would make it financially profitable to develop large bases on the Moon for the sake of the propellant.Another possible resource was recentlydiscovered on the Moon: uranium. Though further analysis showed the surface abundance to be much less than in Earth mines, it may be that there are localized concentrations just as there are on Earth. Indeed this appears to be the case withsome heavy metals such as silver and possibly goldthat appear to be concentrated in some polar craters on the Moon.So even if the uranium is not as abundant as in Earth mines, it may be sufficient to be used for nuclear-powered spacecraft. Then we wouldn't have the problem of large amounts of nuclear material being lofted on rockets on Earth. The physics and engineering ofnuclear powered rockets have been understood since the 60's. The main impediment has been the opposition to launching large amounts of radioactive material from Earth into orbit above Earth. Then we very well could have had nuclear-powered spacecraft launching from the Moon for interplanetary missions, especially when you consider the financial incentive provided by minerals in the asteroids of the asteroid belt.Bob Clark\n\n---------- Post added at 08:00 PM ---------- Previous post was at 07:19 PM ----------It would be a truly watershed moment just creating a SSTO even if it doesn't carry much payload.

While the miner can produce smaller drums that can be used for packing fuel to orbit.Now I am starting to think that for the 'smaller drums' we can actually use the fuel cargo supplied with UCGO. Since like ~9 of them will fill up the fuel tanks of DGIV, they should be enough. Anyway, if we had to haul them, we would have to make them fit in cargo bays and well, more hassle then I think its worth and redesigning the wheel I think.Summary: the miner should produce UCGO fuel cargo for simplicity sake.The larger drums (since I am assuming, alteration of Arrows hover engines to permit landing) should fill up 800,750kg of fuel with say, 5 drums.Assuming 1.25:1 ratio for width\/high large drum size and 160,150 kg for drum,(don't mind my scribbles)[MATH]\\pi hr^2 = [\/MATH](volume of container)[MATH]2r=1.25(h)[\/MATH][MATH]\\pi h(0.625h)^2 = .39\\pi h^3[\/MATH][MATH]~.39\\pi h^3 = ~446.49[\/MATH] ( = (1\/5)\/358.69 of 800,750kg)So the large drum should be;h = ~7.14r = ~4.46Now then, I think either we can do 2 things, be realistic and set the miner (or other vessel) to have fuel containers fill as a function of time, or we can just have the oil drums set to act as UCGO fuel stations.\n\nYeah, probably best for the miner to make normal fuel cargos as I remembered at work that DanSteph has said that UCGO cargos must be able to fit in a 1.3m^3 box.So for the fuel cargo to hold more fuel it would have to stay the same size and just hold a super dense fuel.My main worry with a bigger fuel container was how to get it to orbit but if we're having the Arrow com eto us then that problem is solved.I'll have a go at whipping up a big fuel tank mesh then, don't mind either way whether we have it fill over time or act as a fuel station, it's easy enough to canabalise the miner code.Though wouldn't be able to directly fill the Arrow from a miner-derived tank, would have to produce many UCGO fuel containers but they take zero time to make so wouldn't be too much of a problem.", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:36.003972352Z", "author": "orb", "date": "2012-10-01T12:47:47+0100", "id": "0387e9edaee74e1e7e50ff769218246a", "post_id": "post-251946", "text": "SPACE.com:Weather On Mars Surprisingly Warm, Curiosity Rover FindsDiscovery News:Weather On Mars Surprisingly Warm, Rover Finds", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.663358976Z", "author": "Urwumpe", "date": "2010-05-04T15:44:02+0100", "id": "3df35fdb46eb711a861589c8e655d0a1", "post_id": "post-220631", "text": "Bj said:So what about a list of modules needed for this station?\n\nAt least a few of the inflatables from UCGO... never a bad choice.Otherwise we modules that contain functions like:Green housesMed BayPower supply, power storageHabitatTool storageRover garageFuel storageIn-situ fuel plantWater plantCommunicationBase command\/AdministrationMeteological officeWorkshopGalleyRecreationUMMU respawning :lol:Arnold Schwarzenegger for the terraforming project - With the sound \"look, sa reacter is melting sa ice\".", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:05.64704768Z", "author": "Urwumpe", "date": "2010-06-08T18:30:02+0100", "id": "11e9a005dbb548399c61ab2f0ee5a8c4", "post_id": "post-221006", "text": "Voyager said:By the way, what meshes do we need.

What must be there is a power distribution system, so power from the ISS can be routed to the rest of the early vessel for the construction process.Now, the next missions would be early outfitting - the first part of the truss gets installed, together with a SSRMS like robot arm for assisting the future assembly. The next step would be habitats, which would get installed on the first part of the truss, together with power storage (batteries) and ECLSS tanks (O2, N2) inside the truss. The next part would be the main truss, which would get the propellant tanks and the propulsion system eventually... Once the propulsion system arrives, which would in case of nuclear propulsion also supply electrical power, the long spacecraft could be undocked from the ISS (for stability, since it would overload the stabilization system), and the final outfitting take place some true anomaly away from the ISS. Radiators would get installed, Propellant tanks are launched and installed. Next the shuttles for the way to mars would be installed, and the first consumables are loaded.Finally, the spacecraft would get the Earth-return capsule docked, ideally in a enclosed hangar, and the crew...If nuclear propulsion is not possible, chemical and launching it as Aldrin Cycler might be a good alternative.", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:36.143134464Z", "author": "george7378", "date": "2010-08-29T23:04:02+0100", "id": "fa4785ceaedccec188548f9bdd05ae94", "post_id": "post-252284", "text": "Hi,I am having trouble converting Quicktime (.MOV) files to WMV for use in Windows Movie Maker.

If there actually IS an issue with using later dates (actually STARTING at a later date, not simply time warping there) then it was a bad idea on my part and I will circular file the later date idea in a heartbeat.\n\nI agree the Earth\/Mars relationship changes between years, though I think we are technologically incapable of simulating the proper year.

Such a vehicle might have comparable liftoff thrust to F9, along with higher ISP in a vacuum, and fewer engines (lower cost, less risk of catastrophic engine failure).\n\nAnother advantage of the aerospike is that you don't need that long, wide, nozzle to get the high vacuum Isp.

It would increase the complexity of things, sure, but surely the disconnect\/separation system can't mass over a quarter the mass of the entire vehicle!Also the Atlas had an unusual method to save weight on the propellant tanks. It used what are called \"balloon tanks\". It's based on the idea that inflating a structure can increase its compressional and bending strength. Consider an inflated tire or basketball for example. Then this fact was used to reduce the thickness of the walls of the Atlas tanks. The reduced strength of the walls was made up for by the increased strength due to the internal pressure.In fact for the Atlas its walls are so thin the structure can not stand on its own when empty. When in storage its propellant tanks are filled with nitrogen. Otherwise it would collapse under its own weight:\n\nIt is not a bad thing, it served Atlas well for decades and continues to be used with the Centaur stage. And the SpaceX Falcon tanks use a similar concept (but are beefed up to be self-supporting, they only require pressurisation to withstand flight loads).The fact that Centaur needs to be pressurised to support itself is not problematic, with modern technology the process is automated and alerts are sent to engineers via email.Considering your crusade for the reduction in tank mass, I would have thought you'd have a more positive impression of pressure supported structures.Note the propellant tanks for this hydrogen fueled SSTO weigh more than the engines. This problem of weight is especially true for hydrogen fueled vehicles because the tanks for hydrogen have to be so heavy because of its low density.\n\nI have not read that pdf very closely (looks very interesting though- thank you), butthis pagegives the mass of the STS ET LH2 tank as 29 000 \"pounds\" (approximately 13 200 kilograms) empty. The mass of three SSME is 9531 kilograms (going by figures on Wikipedia) and that is not including thrust structure.And the DIRECT J-130 core stage dry mass figure, with three SSMEs removed, is still roughly two times more massive than the shuttle ET (the tank is supposedly reinforced to withstand the loads of a heavy upper stage, but still thrust structure mass has to be in there somewhere).But think of it like this:Let's say engines make up 25% of a launch vehicle (as shown by the few examples that I gave a page or two back). Let's say that the thrust structure masses the same as the engines, and is also 25% of the dry mass. Let's allocate a further 5% to \"other stuff\", and leave the remaining 45% for the propellant tank mass.If we reduce the tank mass by a whole 50%, the vehicle mass is only reduced by 22.5%.The less the tanks mass as a percentage of dry weight, the less impact lightening them will have. If tanks are only 30% of the vehicle mass, halving the mass of the tanks will only shave 15% of the dry mass off.Ok, so maybe that is still advantageous enough to warrant its existence.

The formatting of your post has greatly improved, however, the quality of its content is still the same.RGClark, I suggest (and not out of jest or sarcasm) that you do a simple cost comparison between a reusable TSTO and reusable SSTO. The conditions are that you have to show your work, and cite proper sources (i.e. NASA studies and technical papers, AIAA studies, etc) and not just things like space news websites. You cannot make baseless, referenceless and dubious claims (i.e. 'with modern materials, this can be reduced by half'). You have to show the reasoning behind the methods you use and your assumptions.Good luck. And have fun!:cheers:\n\nThe cost comparisons to currently existing vehicles come on two fronts. (There is little debate that a reusable SSTO would have lower operational costs than a TSTO oneif it exists. The debate is whether its lower payload would make it worthwhile.)First, a key problem for reducing the cost of spaceflight is that it can only come from reusability. But, the argument goes, reusable spacecraft are more expensive to develop and you need many launches to make that expense worthwhile. Where's the market for that?As I argued before for small SSTO's a large market would be for small privately owned manned SSTO's. In the examples in the post copied at the bottom of the prevous post, both the engines and the lightweight stage already existed. It is only required to marry them together. The cost? How much do you estimate to develop a launcher the size of a small business jet when the rocket engines and the primary structure already exists? How much do you estimate it cost to develop Falcon1?Furthermore for any estimates of rocket launchers it has to be kept in mind such estimates are based on the costs of government financed vehicles in the past.The most important accomplishment of SpaceX may turn out to be they showed in stark terms that a privately developed spacecraft can be developed for 1\/10th the cost of government financed ones.The importance of this can not be overemphasized. So if you estimate a manned launcher may take $3 billion to develop, divide this by 10 to get an idea what it really should cost if privately financed.Secondly, as mentioned in this thread a large portion of launch costs are because of operational costs due to the large labor costs as run as a government program. For the space shuttle this is literally thousands of people to run it. This has been recognized for a while. A key part of the proposal to cut launch costs for the VentureStar reusable launcher was to cut majorly this required labor force:Lockheed Secret Projects: Inside the Skunk Works.By Dennis R. JenkinsOne of the conclusions from the DC-X demonstration program was that it should not take a standing army to operate a launch vehicle. Almost 18,000 workers are employed to maintain and operate the space shuttle fleet, and it takes 60 to 70 days to prepare a shuttle for a new mission. By contrast, the X-33 will require only about 50 and have a 48-hour turnaround, and the VentureStar will require under 300 people and have a turnaround of less than one week. NASA and industry estimate the cost for each flight of a full-scale RLV will be about one-tenth as much as the space shuttle, or roughly $50 million each.\n\nhttp:\/\/books.google.com\/books?id=DU... venturestar&lr=&pg=PA106#v=onepage&q=&f=trueElon Musk also recognized the need to cut the size of the ground crew:The Rocketeers. How a Visionary Band of Business Leaders, Engineers, and Pilots is Boldly Privatizing Space.by Michael BelfioreHarperColins, 2007Musk had identified five major drivers of launch vehicle costs and had set about bringing each one of those down. The first, and perhaps the biggest, was overhead. Looking around the Main Building I could see for myself that Musk ran a tight ship. He had fewer than a hundred employees, including all the engineers, machinists and associated support staff like the receptionists, administrative assistants, and a public relations officer.\"We are an extremely low-overhead company,\" said Musk. \"If we simply handed our blueprints to a Boeing or Lockheed, I think the price would at least double if not more.\"\"There was the rocket itself, with three major components contributing to its cost: engines, structures (the actual body of the rocket as well as fuel and oxidizer tanks), and avionics - the sophisticated computers and software that controlled the other components to guide the rocket through the air to space and into orbit.\"And then there was the launch operation. Musk laughed as he told me how a Lockheed Martin representative boasted to him of his company's \"lean\" launch crew: only three hundred people. \"Now what are those people doing? I can't tell you.\" Falcon 1's launch crew?

If we launch one stack at a time (or otherwise not within the same month or so), we would have to wait for the next launch window to open, which could be a while.About the Moon base; I think that would be rather difficult since the Moon has such a slow spin, it would mean 1 month of continuous LOS, then 1 month of nothing. Unless you where on the pole then it might work out properly depending on the tilt and whatever.So we are going to push each individual module past LEO into a Lunar orbit and construct around the Moon? What about all the launchers?if you look at Ares V - 160,000kg to LEO, or 71,100-60,000kg to TLI. Much less weigh carried per launch meaning more Ares launches, meaning more (virtual) money (each engine, vehicle construction, ext).... a lot of dead weight and fuel to break into LEO. Better, I think to launch to LEO, then with a reusable engine push all the joined modules to Mars.So is anything wrong with Huston? Why do we need to try to make a mission control on the Moon? This would become one really ambitious project:)I agree there, the Arrow, DGIV\/XR2 is a little more past our technological capabilities now. We even have yet to make a true SSTO rocket. Thing is, unless we get some good modeler volunteering right now, and willing to make 2 ships at XR2 quality (both code and mesh) it would be rather difficult to simulate this in Orbiter. *(hint hint)* The best lander would look like Uwumpe's drawing a few posts back.Hey can you make some good satellite meshes? That would be nice.Good idea, a plaque would be easy, just really an indented box. Its just a matter of what to what to write for them.Best they can? :hmm: I'm not sure we would get anything out of it, actually I am not sure of the goal at all. Really its not that hard to get a unrealistic vessel anywhere, (ie Arrow, DGIV\/XR2 with alternate settings) so I think the greater challenge would to actually make our own vessels that would actually have more realistic Mars landings.\n\nI like how you think.Really the concept behind the MBC is to give us a lower gravity to launch our ship from. And Frankly. Something to do. See once the Ship leaves earth its gonna be 7 months before much else needs to be done. With a moon base it gives the project a new series of things to keep interest in the project. MBC resupply. Station building. Lunar exploration missions.As for the Thing of building the Mars ship in orbit and launching it to the moon. The ting is much of the fueling requirements for the ship would be set up on the moon.Still you bring up a great point about the weight issues. So I propose a sort of compromise. The is Launching modules into LEO. Say first four are launched. Put together in orbit. A temporary modular engine is attached the the front five sections are launched to the moon. Center section. Engine launch aft section constructed and launched. So Were not launching the whole thing at once nor going bit by bit.

This past weekend, that effort produced the first drilled sample on Mars in more than a year.Curiosity tested percussive drilling this past weekend, penetrating about 2 inches (50 millimeters) into a target called \"Duluth.\"NASA's Jet Propulsion Laboratory in Pasadena, California, has been testing this drilling technique since a mechanical problem took Curiosity's drill offline in December of 2016. This technique, called Feed Extended Drilling, keeps the drill's bit extended out past two stabilizer posts that were originally used to steady the drill against Martian rocks. It lets Curiosity drill using the force of its robotic arm, a little more like the way a human would drill into a wall at home.\"The team used tremendous ingenuity to devise a new drilling technique and implement it on another planet,\" said Curiosity Deputy Project Manager Steve Lee of JPL. \"Those are two vital inches of innovation from 60 million miles away. We\u2019re thrilled that the result was so successful.\"\n\nNASA's Curiosity rover successfully drilled a 2-inch-deep hole in a target called \"Duluth\" on May 20. It was the first rock sample captured by the drill since October 2016.This image was taken by Curiosity's Mast Camera (Mastcam) on Sol 2057. It has been white balanced and contrast-enhanced.Credits: NASA\/JPL-Caltech\/MSSS\u200bDrilling is a vitally important part of Curiosity's capabilities to study Mars. Inside the rover are two laboratories that are able to conduct chemical and mineralogical analyses of rock and soil samples. The samples are acquired from Gale Crater, which the rover has been exploring since 2012.Curiosity's science team has been eager to get the drill working before the rover leaves its current location near Vera Rubin Ridge. Fortunately, it was near enough to drill targets like Duluth to drive back down the ridge. Sunday's drill sample represents a quick taste of the region before Curiosity moves on.\n\nA close-up image of a 2-inch-deep hole produced using a new drilling technique for NASA's Curiosity rover.

Having captured enough powder inside the drill, engineers will now use the rover's cameras to estimate how much trickles out while running the drill backwards. The drill\u2019s percussion mechanism is also used to tap out powder.As soon as this Friday, the Curiosity team will test a new process for delivering samples into the rover's laboratories.\n\nSource:NASA", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.472431616Z", "author": "Izack", "date": "2010-04-30T02:55:19+0100", "id": "42a566b32e066f1165be04033a4fcc4c", "post_id": "post-219922", "text": "Ark said:I dunno, I'd look at it and think \"Damn, we suck now.\"\n\nAh, so true.Except for me it's \"Damn,yousuck now.\"Err, on second thought I can't really complain about that. :lol:", "thread_id": 14063 }, { "@timestamp": "2023-09-14T07:13:05.660014848Z", "author": "Urwumpe", "date": "2010-05-03T18:57:30+0100", "id": "04cc1cf739eadc6567ff1d8c9e06ee15", "post_id": "post-220599", "text": "Would a blimp work in the low density atmosphere of Mars?", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:36.064250112Z", "author": "N_Molson", "date": "2011-11-26T15:53:52+0000", "id": "647bb7820750e39be50ba398bf11727b", "post_id": "post-251277", "text": "What's that?\n\nRotation of 12 degrees\/second on the Z-axis, to avoid that one side of the spacecraft is overheated by the Sun while the other freezes in the dark.", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.548700928Z", "author": "RGClark", "date": "2010-05-01T15:22:06+0100", "id": "42de997af822d180d464fc5a4ccaa908", "post_id": "post-220075", "text": "The SpaceLaunchReport.com site operated by Ed Kyle provides thespecifications of some launch vehicles. Here's the page for the Falcon1:Space Launch Report: SpaceX Falcon Data Sheet.http:\/\/www.spacelaunchreport.com\/falcon.htmlQuite interesting is that the total mass and dry mass values for theFalcon 1 first stage with Merlin 1C engine give a mass ratio of about20 to 1. This is notable because a 20 to 1 mass ratio is the valueusually given for a kerosene-fueled vehicle to be SSTO. However, thisis for the engine having high vacuum Isp ca. 350 s. The Merlin 1C witha vacuum Isp of 304 s probably wouldn't work.However, there are some high performance Russian kerosene engines thatcould work. Some possibilities:Engine Model: RD-120M.http:\/\/www.astronautix.com\/engines\/rd120.htm#RD-120MRD-0124.http:\/\/www.astronautix.com\/engines\/rd0124.htmEngine Model: RD-0234-HC.http:\/\/www.astronautix.com\/engines\/rd0234.htmHowever, I don't know if this third one was actually built, being amodification of another engine that burned aerozine.Some other possibilities can be found on the Astronautix site:Lox\/Kerosene.http:\/\/www.astronautix.com\/props\/loxosene.htmAnd on this list of Russian rocket engines:Russian\/Ukrainian space-rocket and missile liquid-propellant engines.http:\/\/www.b14643.de\/Spacerockets_1\/Diverse\/Russian%2520engines\/engines.htmThe problem is the engine has to have good Isp as well as a good T\/Wratio for this SSTO application. There are some engines listed thateven have a vacuum Isp above 360 s. However, these generally are thesmall engines used for example as reaction control thrusters in orbitand usually have poor T\/W ratios.For the required delta-V I'll use the fact that a dense propellantvehicle may only require a delta-V of 8,900 m\/s, compared to ahydrogen-fueled vehicle which may require in the range of 9,100 to9,200 m\/s. The reason for this is explained here:Hydrogen delta-V.http:\/\/yarchive.net\/space\/rocket\/fuels\/hydrogen_deltav.htmlThen when you add on the fact that launching near the equator givesyou 462 m\/s for free from the Earth's rotation, we can take therequired delta-V that has to be supplied by the kerosene-fueledvehicle as 8,500 m\/s.I'll focus on the RD-0124 because of its high Isp, 359 s vacuum and331 s sea level. On the \"Russian\/Ukrainian space-rocket and missileliquid-propellant engines\" page its sea level thrust is given as253,200 N, 25,840 kgf. However, the Falcon 1 first stage weighs 28,553kg. So we'll need two of them. Each weighs 480 kg, so two would be 960kg. This is 300 kg more than the single Merlin 1C. So the dry mass ofthe Falcon 1 first stage is raised to 1,751 kg. There is a RD-0124Mlisted on the Astronautix page that only weighs 360 kg, but its sealevel Isp and thrust are not given, so we'll use the RD-0124 untilfurther info on the RD-0124M is available.Taking the midpoint value of the Isp as 345 s we get a delta-V of345*9.8ln(1 + 27102\/1751) = 9,474 m\/s (!) Note also the achieved delta-V would actually be higher than this because the trajectory averagedIsp is closer to the vacuum value since the rocket spends most of thetime at altitude.This calculation did not include the nose cone fairing weight of 136kg. However, the dry mass for the first stage probably includes theinterstage weight, which is not listed, since this remains behind withthe first stage when the second stage fires. Note then that theinterstage would be removed for the SSTO application. From looking atthe images of the Falcon 1, the size of the cylindrical interstage incomparison to the conical nose cone fairing suggests the interstageshould weigh more. So I'll keep the dry mass as 1,751 kg.Now considering that we only need 8,500 m\/s delta-V we can add 636 kgof payload. But this is even higher than the payload capacity of thetwo stage Falcon 1!We saw that the thrust value of the RD-0124 is not much smaller thanthe gross weight of the Falcon 1 first stage. So we can get a vehiclecapable of being lifted by a single RD-0124 by reducing the propellantsomewhat, say by 25%. This reduces the dry weight now since oneRD-0124 weighs less than a Merlin 1C and the tank mass would also bereduced 25%. Using an analogous calculation as before, the payloadcapacity of this SSTO would be in the range of 500 kg.We can perform a similar analysis on the Falcon 1e first stage thatuses the upgraded Merlin 1C+ engine. Assuming the T\/W ratio of theMerlin 1C+ is the same as that of the Merlin 1C, the mass of the twoof the RD-124's would now be only 100 kg more than the Merlin 1C+.The dry mass and total mass numbers on the SpaceLaunchReport page forthe Falcon 1e are estimated. But accepting these values we would beable to get a payload in the range of 1,800 kg. This is again higherthan the payload capacity of the original two stage Falcon 1e. In factit could place into orbit the 1-man Mercury capsule.The launch cost of the Falcon 1, Falcon 1e is only about $8 million -$9 million. So we could have the first stage for that amount orperhaps less since we don't need the engines which make up the bulk ofthe cost. How much could we buy the Russian engines for? This articlesays the much higher thrust RD-180 cost $10 million:From Russia, With 1 Million Pounds of Thrust.Why the workhorse RD-180 may be the future of US rocketry.Issue 9.12 | Dec 2001\"This engine cost $10 million and produces almost 1 million pounds ofthrust.

RP-LOX Aerojet AJ26-60, which is the formerRussian NK-43 engine. Thrust to weight of 122 to1 compares to the Space Shuttle Main Engine\u2019s(SSME) 67 to 1 and specific impulse (Isp = 348.3seconds vacuum) is 50 to 60 seconds better thanthe Atlas II, Delta II, or Delta III RP-LOX engines.A total of 831 engines have been tested for194,000 seconds. These engines are available for$4 million each, which is about 10% the cost of aSSME.\"http:\/\/mae.ucdavis.edu\/faculty\/sarigul\/aiaa2001-4619.pdfThen the much lower thrust RD-0124 could quite likely be purchasedfor less than $4 million. So the single RD-0124 powered SSTO could bepurchased for less than $12 million.Even though the mathematics says it should be possible, and has beenfor decades, it is still commonly believed that SSTO performance withchemical propulsion is not possible even among experts in the spaceindustry:Space Tourism is a HoaxBy Fredrick Engstrom and Heinz Pfeffer11\/16\/09 09:02 AM ET\"In 1903, the Russian scientist Konstantin Tsiolkovsky established theso-called rocket equation, which calculates the initial mass of arocket needed to put a certain payload into orbit, given that theorbital speed is fixed at 28,000 kilometers per hour, and that themaximum speed of the gas exhausted from the rocket that propels itforward is also fixed.\"You quickly find that the structure and the tanks needed to containthe fuel are so heavy that you will never be able to orbit asignificant payload with a single-stage rocket. Thus, it is necessaryto use several rocket stages that are dumped on the way up to get anynet mass, i.e. payload, into orbit.\"Let us look at the most successful rocket on the market \u2014 theEuropean Ariane 5. Its start weight is 750 tons, of which 650 tons arefuel, 80 tons are structure and around 20 tons are left for low Earthorbit payload.\"You can have a different number of stages, and you can look for minorimprovements, but you can never get around the fact that you need bigmachines that are staged to reach orbital speed. Not much has happenedin propulsion in a fundamental sense since Wernher von Braun\u2019s Saturnrocket. And there is nothing on the horizon, if you discountcontrolling gravity or some exotic technology like that.

This is in the salary range of many just upper class individuals. Then such orbital rockets with financing will be in the cost range of many such individuals.A combination of factors suggest this is possible. First, with mass production the cost of the rocket structure and of the engines will drop significantly. Also, though the Falcon 1 is priced at about $8 million, remember a large proportion of this is to cover development cost. The large majority of this cost was for the development of the engines. But neither of these two SpaceX engines would be used for the SSTO purpose. Instead would be used the much cheaper for their size Russian engines.We can estimate how much they would cost based on their size and the costs for much larger, i.e., more powerful, Russian engines. The 1,000,000 lbs. thrust RD-180 costs $10 million. The 400,000 lbs. thrust NK-33 costs $4 million. Based on this we can estimate the cost of the 60,000 lbs. thrust RD-0124 I was recommending for the SSTO purpose as $600,000.Another reason for why such SSTO's will be lower cost than the $8 million Falcon 1 is that the manufacturing cost is actually only a fraction of the launch cost. See for example the estimates in Tables 3 and 4 here:When Physics, Economics, and Reality Collide. The Challenge of Cheap Orbital Access.by John M. Jurist, M.D., Sam Dinkin, Ph.D, David Livingston, DBAhttp:\/\/www.colonyfund.com\/Reading\/papers\/phys_econ_leo.html#elvNote then the methods for achieving such high mass ratios as with the Falcon 1 first stage don't appear to be especially hard. See for example the description of the Falcon 1 propellant tanks given here:Falcon 1 Overview.http:\/\/www.spacex.com\/falcon1.php#first_stageThey appear to use a combination of methods known for decades such as a common bulkhead and an isogrid design. So using these methods, similar high mass ratios could easily be achieved by other aerospace companies. Actually little in research and development costs would be required for the structures.There is another key cost that figures into launch costs mentioned in the \"When Physics, Economics, and Reality Collide: The Challenge of Cheap Orbital Access\" article. That is the cost of range access, usually provided by governments. With wide numbers of privately owned rockets launching daily this cost could be reduced significantly.A big component of the research and development costs however would be the actual flight tests. This would be significantly reduced with reusable systems.For this to have a high demand you would need for it to be manned-flight capable. The Falcon 1e sized SSTO would require two RD-0124 engines for a 1,800 kg payload capacity, but would be able to loft a Project Mercury-sized capsule:Mercury.http:\/\/www.braeunig.us\/space\/specs\/mercury.htmYou would also need a lightweight reentry system. Inflatable heat shields may fit the bill:NASA Launches New Technology: An Inflatable Heat Shield.08.17.09http:\/\/www.nasa.gov\/topics\/aeronautics\/features\/irve.htmlPod People.They're the ones thinking outside the space capsule.* By James Oberg* Air & Space Magazine, November 01, 2003\"IN 1964, MOST VIEWERS OF TELEVISED SPACE \"SHOTS,\" AS THEY WERE CALLED THEN, knew what it took to protect a spacecraft from the fire of reentry. It took big, heavy shields bolted to pressurized metal vessels. One of the most nerve-racking moments of the early space program had been the final minutes of John Glenn\u2019s 1962 Mercury flight, when Mission Control waited to learn whether his shield had remained attached to the Friendship 7 capsule during the violent return.\"Two years later, on June 10, 1964, another, much lighter vehicle entered the atmosphere with no one on board. In engineering terms it was nearly as daring as the Mercury flights had been. Launched on a sounding rocket to an altitude of 96 miles over New Mexico, the craft dove back toward Earth at a speed of more than 5,000 mph. Being so light, it didn\u2019t generate as much heat from atmospheric friction as Glenn\u2019s capsule had, so it had only a thin coating of thermal protection\u2014no shield. Odder still, it was inflated like a balloon in a Thanksgiving day parade.\"http:\/\/www.airspacemag.com\/space-exploration\/cit-oberg.htmlThis second, which involves a lifting body inflatable heat shield, would result in significant reduction in reentry heating by making use of shapes optimized for high lift\/drag ratio at hypersonic speed.Bob Clark---------- Post added at 02:22 PM ---------- Previous post was at 02:20 PM ----------I'm looking for a numerical trajectory integration program.These are the conditions under which I want to estimate the required delta-V to orbit:1.)use a dense propellant such as kerosene\/LOX; dense propellants are known to reduce gravity losses.2.)use a moderate to high liftoff thrust\/weight ratio, say, 1.4 and above; high liftoff T\/W also reduces gravity losses.3.)launch near equator to get the ca. 460 m\/s tangential boost.4.)only get to 100 km, the altitude considered space, to just launch satellites or make orbital transfers, not for long term orbits.Anyone know if the Orbiter sim could do this?Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.082902528Z", "author": "Andy44", "date": "2010-08-13T00:35:48+0100", "id": "8c1d8251332ea18ecbcc9bbadba87ef8", "post_id": "post-219539", "text": "Shooting out of jetliner windows is always tough.

And there the \"lower structural mass for smaller tanks\" fallacy will also tumble, since the structural mass reduction for the smaller tank volume will not be as high as the fluffy assumption makes it sound, since you have to deal with higher forces acting on the structure. In reality, you will get punished by the heaviest parts of any LV: The engines. The lower performance fuels will mean you will have surplus engines quickly in flight, that you can't use effectively.

ChemCam then observes the flash through a telescope and analyzes the spectrum of light to identify the chemical elements in the target.Click on image for hi-res \/ details\u200bResearchers prepare for a test of the Chemistry and Camera (ChemCam) instrument that will fly on NASA's Mars Science Laboratory mission. Image credit NASA\/JPL-Caltech\/LANLThat information about rocks or patches of soil up to about 7 meters (23 feet) away will help the rover team survey the rover's surroundings and choose which targets to drill into, or scoop up, for additional analysis by other instruments on Curiosity. With the 10 science instruments on the rover, the team will assess whether any environments in the landing area have been favorable for microbial life and for preserving evidence about whether life existed. In late 2011, NASA will launch Curiosity and the other parts of the flight system, delivering the rover to the surface of Mars in August 2012.Wiens, a geochemist with the U.S. Department of Energy's Los Alamos National Laboratory, serves as ChemCam's principal investigator. An American and French team that he leads proposed the instrument during NASA's 2004 open competition for participation in the Mars Science Laboratory project, whose rover has since been named Curiosity.In 1997, while working on an idea for using lasers to investigate the moon, Wiens visited a chemistry laboratory building where a colleague, Dave Cremers, had been experimenting with a different laser technique. Cremers set up a cigar-size laser powered by a little 9-volt radio battery and pointed at a rock across the room.\"The room was well used. Every flat surface was covered with instruments, lenses or optical mounts,\" Wiens recalls. \"The filing cabinets looked like they had a bad case of acne. I found out later that they were used for laser target practice.\"Cremers pressed a button. An invisible beam from the laser set off a flash on a rock across the room. The flash was ionized gas, or plasma, generated by the energy from the laser exciting atoms in the rock. A spectrometer pointed at the glowing plasma recorded the intensity of light at different wavelengths for determining the rock's atomic ingredients.Researchers have used lasers for inducing plasmas for decades. What impressed Wiens in this demonstration was the capability to do it with such a low-voltage power source and compact hardware. Using this technology for a robot on another planet seemed feasible. From that point, more than a decade of international development and testing resulted in ChemCam being installed on Curiosity in September 2010.The international collaboration came about in 2001 when Wiens introduced a former Los Alamos post-doctoral researcher, Sylvestre Maurice, to the project. The core technology of ChemCam, laser-induced breakdown spectroscopy, had been used for years in France as well as in America, but it was still unknown to space scientists there. \"The technique is both flashy and very compelling scientifically, and the reviewers in France really liked that combination,\" Maurice said. A French team was formed, and work on a new laser began.\"The trick is very short bursts of the laser,\" Wiens said. \"You really dump a lot of energy onto a small spot -- megawatts per square millimeter -- but just for a few nanoseconds.\"The pinhead-size spot hit by ChemCam's laser gets as much power focused on it as a million light bulbs, for five one-billionths of a second. Light from the resulting flash comes back to ChemCam through the instrument's telescope, mounted beside the laser high on the rover's camera mast. The telescope directs the light down an optical fiber to three spectrometers inside the rover. The spectrometers record intensity at 6,144 different wavelengths of ultraviolet, visible and infrared light. Different chemical elements in the target emit light at different wavelengths.If the rock has a coating of dust or a weathered rind, multiple shots from the laser can remove those layers to provide a clear shot to the rock's interior composition. \"We can see what the progression of composition looks like as we get a little bit deeper with each shot,\" Wiens said.Earlier Mars rover missions have lacked a way to identify some of the lighter elements, such as carbon, oxygen, hydrogen, lithium and boron, which can be clues to past environmental conditions in which the rock was formed or altered. After NASA's Mars Exploration Rover Spirit examined an outcrop called \"Comanche\" in 2005, it took years of analyzing indirect evidence before the team could confidently infer the presence of carbon in the rock. A single observation with ChemCam could detect carbon directly.ChemCam will be able to interrogate multiple targets the same day, gaining information for the rover team's careful selection of where to drill or scoop samples for laboratory investigations that will take multiple days per target. It can also check the composition of targets inaccessible to the rover's other instruments, such as rock faces beyond the reach of Curiosity's arm.The instrument's telescope doubles as the optics for the camera part of ChemCam, which records images on a one-megapixel detector. The telescopic camera will show context of the spots hit with the laser and can also be used independently of the laser.The French half of the ChemCam team, headed by Maurice and funded by France's national space agency, provided the instrument's laser and telescope. Maurice is a spectroscopy expert with the Centre d'\u00c9tude Spatiale des Rayonnements, in Toulouse, France. Los Alamos National Laboratory supplied the spectrometers and data processor inside the rover. The optical design of the spectrometers came from Ocean Optics, Dunedin, Fla.The ChemCam team includes experts in mineralogy, geology, astrobiology and other fields, with some members also on other Curiosity instrument teams.With the instrument now installed on Curiosity, testing continues at NASA's Jet Propulsion Laboratory, Pasadena, Calif.

I had forgotten though that the Falcon 1e, which SpaceX wants to move to for small launches anyway, has about twice the propellant load of the Falcon so it could form the SSTO.Aerospike nozzles.So how to get the altitude compensation? The aerospike[1],[2] is the most extensively studied method of altitude compensation so to get to this quickly it would be nice if this could be used. However, the aerospike (or plug nozzle for the shortened version) requires a toroidal combustion chamber. This would require significant modification of the engine.However, one concept for getting an aerospike engine uses multiple small chambers arranged around a central spike. This was the idea for the X-33\/VentureStar[3]. It was also used earlier on the Beta SSTO concept of Koelle[4],[5]. This could be conveniently used on the Falcon 9 first stage because of its multiple engines. The idea would be to greatly shorten the nozzles on the Merlins and arrange them around a central spike.We need an estimate of the mass of the Falcon 9 first stage. This environmental assess- ment report on the SpaceX Grasshopper VTVL test vehicle[6] gives on p. 7 (page 17 according to the numbering as a PDF file) the Falcon 9 first stage kerosene load as 24,900 gallons and 38,900 gallons of LOX. Using a density of .820 gm\/cc for keroseneand 1.14 gm\/cc for LOX, this amounts to about 245,000 kg propellant for the first stage.Falcon 9 with aerospike nozzle becomes SSTO.SpaceX has said the Falcon 9 first stage has a better than 20 to 1 mass ratio. This would give it a first stage dry mass of 13,000 kg. But this is using the Merlin 1C engine. From the thrust level and thrust\/weight ratio[7] for this engine we can estimate its mass as about 650 kg. The Merlin 1D is supposed to be lighter, estimated as 440 kg. Using these brings the dry mass down to 11,000 kg.The question is what would be the weight with the truncated nozzles and aerospike? A complaint against the aerospike used on the X-33 is that it had a worse T\/W ratio than other LH2\/LOX engines. However it had been planned for the full VentureStar version to use lightweight ceramics for the aerospike, expected to double the T\/W ratio to about 80 to 1, better than the SSME's. With the advances in ceramics necessitated by the research and test flights with the hypersonic vehicles such high temperature lightweight ceramics should be further along now than they were with the VentureStar. For instance, the method of transpiration cooling using ceramics should make rocket engine combustion chambers and nozzles lighter and more reusable[8]. So I'll assume the total engine weight remains the same with the aerospike.As before I'll use the Merlin Vacuum Isp in calculating the delta-V and take the required delta-V to orbit as 9,150 m\/s for kerosene engines. Then we can get 6,000 kg payload:342*9.8ln(1 + 245\/(11 + 6)) = 9,167 m\/s.An SSTO is best utilized as a reusable though. Estimates of the added weight of reentry\/landing systems are in the range of 28% [9]. However, with modern materials this probably can be cut to half that. Then the payload will be reduced to about 4.5 metric tons.\"An increase of 10% in Isp corresponds to an increase in 100% in payload.\"This example illustrates well the importance of altitude compensation. Using it we are able to increase our engine Isp by 10% or more, to the extent we can achieve an SSTO with significant payload. Note that because of the rocket equation just being able to increase the Isp by 10% is no trivial feat. A rule of thumb among propulsion engineers is that \"an increase of 10% in Isp corresponds to an increase in 100% in payload\"[10]. I'll illustrate this with a single stage vehicle. A common estimate is that a kerosene-fueled SSTO needs a mass ratio of 20 to carry significant payload. Let's say a Falcon 9 sized rocket had instead high efficiency engines such as the NK-33[11] with an Isp of 331 s. You would need three of these. These have better thrust\/weight than the Merlin 1C. So the dry weight is reduced to about 11 mT. Then it could carry a payload of 4.5 mT:331*9.8ln(1 + 245\/(11 + 4.5)) = 9,150 m\/s.With vacuum optimized nozzles high efficiency engines such as the NK-33 can get an Isp at 360+ s. Ten percent higher Isp than 331 s is at 364 s. Using this as the Isp allows a payload of 9.4 mT: 364*9.8ln(1 + 245\/(11 + 9.4)) = 9,150 m\/s.Falcon Heavy with aerospike matches phase 1 SLS a hundred times cheaper.Interestingly an improvement in payload using altitude compensation also applies to staged vehicles. A preliminary calculation showed that with a two-stage vehicle you can increase your payload in the range of 25% to 30%. The improvement can be even better if the vehicle uses parallel staging, perhaps up to 50%. This is because with parallel staging the second stage still has to use the same nozzles as a lower stage because they still fire from the ground.I'll illustrate this with the Falcon Heavy. SpaceX has said its side boosters will achieve a 30 to 1 mass ratio[12]. Reportedly the lower stages also will be stretched to hold more propellant. A posting on the NASASpaceFlight forum suggests a stretched version of the Falcon 9 will have 480,000 kg gross mass[13]. I'll estimate the stretched Falcon 9 based boosters as having a 435 mT propellant load and 15 mt dry mass. The central core stage has to be stronger since it holds the upper stage as well as the heavy payload. I'll take the dry mass for this lower core stage as 20 mT with the same 435 mT propellant load.For the upper stage, I'll take the propellant load as 30 mT and the dry mass + fairing as 6 mT. For the vacuum Isp of the Merlin 1D I'll take the announced 310 s, and for the Isp of the upper stage, that of the Merlin Vacuum, 342 s. Then we can lift a payload of 51 mT:310*9.8ln(1 + 2*435\/(2*15 + 435 + 20 + 36 + 51)) + 310*9.8ln(1 + 435\/(20 + 36 + 51)) + 342*9.8ln(1 + 30\/(6 + 51)) = 9,155 m\/s.Now suppose we use altitude compensation to be able to get 342 s vacuum Isp for all the engines. Then we could lift 70 mT:342*9.8ln(1 + 2*435\/(2*15 + 435 + 20 + 36 + 70)) + 342*9.8ln(1 + 435\/(20 + 36 + 70)) + 342*9.8ln(1 + 30\/(6 + 70)) = 9,150 m\/sThis means we could get a 70 mT launcher from essentially the same vehicle as the Falcon Heavy by using altitude compensation on the engines. SpaceX has said they intend to sell the Falcon Heavy for the range of $80 to $125 million per launch. The modifications to the aerospike nozzle should be relatively low cost compared to designing a whole new engine so the price should still be in this range.Compare this to the estimates of the costs of the SLS program:Space Launch System.\"Program costs.During the joint Senate-NASA presentation in September 2011, it wasstated that the SLS program has a projected development cost of $18billion through 2017, with $10B for the SLS rocket, $6B for the OrionMulti-Purpose Crew Vehicle and $2B for upgrades to the launch pad andother facilities at Kennedy Space Center. An unofficial NASAdocument estimates the cost of the program through 2025 will total atleast $41B for four 70 metric ton launches (1 unmanned in 2017, 3manned starting in 2021). The 130 metric ton version should not beready earlier than 2030.\"http:\/\/en.wikipedia.org\/wiki\/Space_Launch_System#Program_costsIf that estimate for the total costs of the SLS is correct then that's $10 billion per launch for the interim 70 mT payload vehicle. That's two orders of magnitude higher than the Falcon Heavy with altitude compensation.Reusable first stage Falcon 9 with aerospike also serves as a reusable booster.This is for the expendable version of the Falcon stages. However, another benefit of the reusable version is that it could serve as the first stage of the reusable booster program (RBS) of the Air Force[14].Reusable Falcon 9 with aerospike also as next-generation shuttle.Another interesting possibility is suggested by the recent report of investigations of bringing back the shuttle as a commercial satellite launcher[15],[16]. My view is that the shuttle orbiter is too heavy for that role, ca. 80 mT in dry mass. This cuts greatly into the payload capacity. According to the reports the investigations also considered building their own shuttle but using the advancements made since the shuttle was designed. Then the reusable Falcon SSTO could be used to launch small payloads or even crew capsules. It could be modeled on the aerodynamic design of the shuttle since the aerodynamics for that are so well studied. Since kerolox has an overall density about 1,000 kg\/m^3, the propellant could fit within the 300 m^3 shuttle-sized payload bay[17]with 55 m^3 left over. For a cargo only version we could also use the 75 m^3 sized volume of the crew cabin, for a total of 130 m^3.The stretched version of the Falcon 9 first stage to be used for the side boosters of the Falcon Heavy are expected by SpaceX to have 30 to 1 mass ratio. The improved mass ratio over the current Falcon 9 first stage is probably coming from the fact that making your rocket larger in general improves your mass ratio, the fact that the new Merlin 1D is lighter, and also the fact the boosters do not have to support the weight of the upper stage and payload of the full vehicle. Using a 435 mT propellant load and a 15 mT dry mass, this could launch 15.3 mT: 342*9.8ln(1 + 435\/(15 + 15.3)) = 9,155 m\/s. If you take the reentry\/landing systems mass with modern materials as 14% of the dry mass this takes up 2.1 mT from the payload, so to 13.2 mT. To scale up the space shuttle design for a 435 mT propellant tank compared to a 245 mT tank, the linear dimensions would only have to be scaled up by 20%.Bob Clark1.)Aerospike Engine.http:\/\/www.aerospaceweb.org\/design\/aerospike\/main.shtml2.)Nozzle Design.by R.A.

The reason was the lower Isp of theMerlin was made up for by its lower weight:SpaceX Propulsion.http:\/\/images.spaceref.com\/news\/2010\/SpaceX_Propulsion.pdfNow note that the biggest single contributor to the vacuum Isp of anengine is not the chamber pressure, but the nozzle length. Forexample, the Merlin Vacuum raises its vacuum Isp to 342 s from the 304s Isp of the Merlin 1C by having a longer nozzle, even though thechamber pressure remains the same, ca. 100 bar.So I'll redo the calculation for the SSTO using the SpaceX Falcon 1first stage but using Merlin engines this time. We'll assume thatusing altitude compensation we are able to get an engine with the samevacuum Isp as the Merlin Vacuum but able to launch from ground.We'll use the soon to be introduced Merlin 1D:SpaceX Plans To Be Top World Rocket Maker.Aug 11, 2011By Guy NorrisSan Diegohttp:\/\/www.aviationweek.com\/aw\/generic\/story.jsp?id=news\/awst\/2011\/08\/08\/AW_08_08_2011_p27-354586.xml&headline=SpaceX%20Plans%20To%20Be%20Top%20World%20Rocket%20Maker&channel=defenseUsing the 160 to 1 thrust\/weight ratio and 155,000 lbs. vacuum thrustgiven, it has a mass of 970 lbs., 440 kg. However, this would make itoverpowered for the Falcon 1 first stage only. So we'll use two copiesof this stage powered by a single Merlin 1D.The original Falcon 1 first stage with the Merlin 1C engine has a dry massof 1,360 kg. I estimated the mass of the Merlin 1C in the prior post tobe 650 kg. So without the engine, the stage weighs 710 kg. So two ofthem will be 1,420 kg without engines, and adding on the Merlin 1Dengine gives this a mass of 1,860 kg.The propellant mass of the two copies of the first stage is 43,080kg. Then to calculate the payload that can be carried I'll again justuse the vacuum Isp and take the required delta-V as 9,150 m\/s. Weconclude a payload of 1,140 kg can be lofted:342*9.8ln(1 + 43,080\/(1,860 + 1,140)) = 9,160.Now we'll estimate how much the payload can be if we use a higherenergy density fuel such as methylacetylene and use lightweightcomposites for the stage. I'll get a rough idea how high the Isp canbe for this case by assuming it is increased proportionally to thesame degree as for the high efficiency engine case. That is, usingmethylacetylene in the high efficiency case resulted in increasing thevacuum Isp to 384 s from the 360 s vacuum Isp for the kerosene.Assuming the vacuum Isp will be increased to the same proportion heregives us a vacuum Isp of 365 s for methylacetylene and the Merlin 1Dengine.For the reduced stage weight using composites, assume again it willbe reduced by 40% aside from the engines. Then the stage weight withthe Merlin 1D engine will be .6*1,420 + 440 kg = 1,290 kg. Then willbe able to loft a payload of 2,320 kg:365*9.8ln(1 + 43,080\/(1,290 + 2,320)) = 9,160 m\/s.Also, quite likely SpaceX could make a half-size version of theMerlin 1D engine. So you could use a single copy of the Falcon 1 firststage. Then the payload would be approximately cut in half, 570 kg forthe kerosene\/standard stage version and 1,160 kg for themethylacetylene\/composite stage version.Note that low chamber pressure, low performance engines can also beused to power the SSTO's is extremely important. Such engines haveless complicated combustion cycles and have to withstand much lessstrenuous operating regimes. This makes them cheaper, simpler, easierto maintain, and easier to make reusable. So the most costly componentof any rocket, the engines, become markedly cheaper for the proposedSSTO.What is key though is to come up with ways to get the needed altitudecompensation without adding on too much to the engine weight. In afollowing post I'll discuss some methods this might be accomplished.Bob Clark\n\n", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:35.937295616Z", "author": "Suzy", "date": "2012-08-06T21:22:33+0100", "id": "4c49b467f49f0c931d5f75fb327553df", "post_id": "post-251727", "text": "Ripley said:Have you seen this?\n\nNASA page with caption", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.085929984Z", "author": "Andy44", "date": "2011-04-04T02:09:50+0100", "id": "843877e5ccca326ba179a04e46f3b5b9", "post_id": "post-219555", "text": "Still alive", "thread_id": 14022 }, { "@timestamp": "2023-09-14T07:13:05.643346176Z", "author": "Izack", "date": "2010-05-26T05:30:01+0100", "id": "4d53558bc61e5732ee993b70b8918e58", "post_id": "post-220971", "text": "Bj said:So far SSTO ships don't exist yet. --I thought we scratched those off? :shrug:\n\nI must have missed the memo. :uhh:I suppose 'superhero' is an exaggeration.

Simply because a parachute will alone weight 4% of the landing mass, a heat shield around 20% of the landing mass. Landing gear adds around 8% of the landing mass, alternative landing systems are between 2% (crushable structure, no reuse possible) and 5% (airbags, no powered landing possible). So at landing, even if you avoid using a parachute: More than 28% of your landing mass will be reserved. And you can't just make the rocket bigger for compensating this, like you could do on expendable rockets. The whole system has to grow to a point that the numbers work out again - and might never work out for some missions.If it would be easy to build an SSTO we would already have one.\n\nThe masses for the extra structures needed for reusability are far less than those. And SpaceX has already shown reusability of the engines with the Grasshopper. I admit though this has to be shown with rapid reuse.A key reason SSTO has not been used is lack of altitude compensating engines. Techniques for doing this however have been tested for decades, such as the aerospike. IF altitude compensation is used on a SSTO the payload increases dramatically.Bob Clark---------- Post added at 10:45 AM ---------- Previous post was at 10:40 AM ----------Hlynkacg said:What leads you to conclude that the F9 first stage is SSTO capable.

In addition to the gravity loss term, drag loss term, and steering loss term, there should be a fourth term for back pressure losses.Most trajectory codes, and in particular the industry-standard POST and OTIS codes, add this fourth term because it accounts for the difference between vacuum thrust and thrust at any given altitude as a delta-V loss rather than a specific impulse loss. When calculations are performed in this fashion, \"Trajectory averaged Isp\" isn't a helpful number. The difference between thrust at a given altitude and vacuum thrust is accounted for on the delta-V part of the budget rather than the Isp. It's a bookkeeping expedient - keeping all the deviations from ideal on one side of the equation.RGClark's understanding of Mitchell Burnside Clapp's argument in post 136 is incomplete. Using the vacuum Isp is industry practice, as explained above, but all that the linked post really claims is that a variety of stages have in excess of 30,000 ft\/s of delta-V, that 30,000 ft\/s is \"SSTO-class\" delta-V, and that many of them use dense propellants. Indeed, the ones using dense propellants are generally smaller than the ones using hydrogen, and while the mass ratios of such stages need to be higher for lower Isp propellants, the increase in propellant density that typically accompanies lower Isp makes that easier to achieve.Burnside Clapp does NOT argue that one should \"Just use 30,000 ft\/s.\" That's the whole point of argument linked in post 106 of this thread. Lower Isp propellants need somewhat less delta-V to orbit because of the reduction in gravity losses. It's about a 1000 ft\/sec advantage. It's nothing to do with density (except for perhaps a modest benefit in reduced drag losses), but just a \"accelerates faster earlier in the trajectory\" effect, which causes the reduction in gravity loss. But lower Isp fuels are generally also denser ones, so you can see how the two concepts get linked together.The conclusion of this line of reasoning is that while a hydrogen-based SSTO might be possible, a clear understanding of the engineering challenges of working with hydrogen and developing a vehicle that uses it might lead a designer to conclude that a dense-propellant, lower-Isp-based SSTO might be an easier engineering challenge, and have other operational advantages.Whether an SSTO is itself a good idea is an entirely separate matter. TSTO's have advantages in gross weight and payload fraction, but the upper stage has to support stage 1 burnout g fully loaded, and the lower stage has to support all that weight at burnout g as well. These conditions impose non-trivial structural penalties. A dispositive answer is design, market, and technology dependent, and while not yet definitive, the evidence at the moment seems to favor a TSTO approach.\n\nYou are correct that the origin of the reduction in gravity loss for \"dense\" propellants is due, counterintuitively, to their lower Isp and that the delta-V to orbit for all dense propellants is not 30,000 fps for all of them. The difference though between the Isp's of the hydrocarbon fuels being considered is relatively small compared to the large difference between hydrogen and kerosene, so 30,000 fps is being taken as a catch all delta-V for all the hydrocarbon fuels. For hydrogen though, the delta-V to orbit being in the range of 31,000 fps is significantly larger and this should be taken into account.BTW, if you want to see a mathematical argument for this reduction in gravity drag due to lower Isp see:A Flexible Reusable Space Transportation System.Steven S.

Let's swap these out for the high efficiencyNK-33. The sustainer engine used was theLR89-5at 720 kg. At 1,220 kg the NK-33 weighs 500 kg more. So removing both the sustainer and booster engines to be replaced by the NK-33 our loaded mass becomes 117,526 kg and the dry mass 2,826 kg, and the mass ratio 41.6 (!).For the trajectory-averaged Isp, notice this is not just the midpoint between the sea level and vacuum value, since most of the flight to orbit is at high altitude at near vacuum conditions. A problem with doing these payload to orbit estimates is the lack of a simple method for getting the average Isp over the flight for an engine, which inhibits people from doing the calculations to realize SSTO is possible and really isn't that hard. I'll use a guesstimate Ed Kyle uses, who is a frequent contributor to NasaSpaceFlight.com and the operator of the Spacelauncereport.com site. Kyle takes theaverage Isp as lying 2\/3rds of the way upfrom the sea level value to the vacuum value. The sea level value of the Isp for the NK-33 is 297 s, and the vacuum value 331 s. Then from this guesstimate the average Isp is 297 + (2\/3)(331 - 297) = 319.667, which I'll round to 320 s.Using this average Isp and a 8,900 m\/s delta-V for a flight to orbit, we can lift 4,200 kg to orbit:320*9.8ln((117,526+4,200)\/(2,826+4,200)) = 8,944 m\/s.

However, recently I found it even gives an answer for an SSTO vehicle.This is the answer I got when I used the numbers of the above example:-------------------------------------------------------------Mission Performance:Launch Vehicle: User-Defined Launch VehicleLaunch Site: Cape Canaveral \/ KSCDestination Orbit: 200 x 200 km, 28 degEstimated Payload: 4319 kg95% Confidence Interval: 3077 - 5820 kg\"Payload\" refers to complete payload system weight, including any necessary payload attachment fittings or multiple payload adaptersThis is an estimate based on the best publicly-available engineering and performance data, and should not be used for detailed mission planning. Operational constraints may reduce performance or preclude this mission.--------------------------------------------------------------The estimator requires you to input an Isp and thrust for the engines. This is meant the vacuum Isp and thrust. The program takes into account the losses due to reduced exhaust velocity at sea level and low altitude.For this case I used the 331 s vacuum Isp and 1,636 kN vacuum thrust of the NK-33.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.517891072Z", "author": "Notebook", "date": "2010-05-01T08:09:36+0100", "id": "61dc853487f9706c197d98bcaf880240", "post_id": "post-220043", "text": "Having actualy sat in one, I can't recommend it.

But I see differently. For me a traffic jam is like having the whole road posing for you, it's an entire scene in which slow motion you can capture many emotions. In this picture, which I composed purely by instinct (that's what 4 years of oil painting did to me) I managed to discard all the anxiety that is usually invoked by the activity of having to wait for your turn to move, instead I centered upon the direction boards and an outdoor ad, which have this particularly fitting portrait of a woman who seems to be waiting, but in an expression that is so serene. A very unique thing that I have managed to found out about traffic jams as I have 23 years of experiencing it is that, when the jam moves, the whole world moves with you, and so it gives the illusion that as you are changing, the world follows you with it, or the other way around. So this picture, at least for me, invoked a feeling that rather than rushing all the things around and being impatient, we can just be happily waiting, for the world to change.In LineThe separator line, which here is very long like a snake, in a rare moment before one of those cars would try to slip into any space that they can find, which would have ruined this kind of composition, but luckily I captured it right in that moment, and with the motorcycle in the edge acting as if it's the head of the snake. And of course, the wet asphalt and the diffracting red light of the lamps from the windscreen adds a particularly beautiful ambiance.InfiltrationSome people just can't wait, in this particular situation, the whole gap which purpose is for a safety net is being used by impatient drivers to go their way, and the effort to drive in one of those is like climbing up the mountains of troubles that is in front of you, a stark contrast to my previous photo which captures the sereneness of traffic jams, this one, just 15 minutes later, captured the hurrying folks who just can't wait.In anticipationI captured this particular frame in what is near the end of the jam, there's a crossroad ahead of this picture, an exit from the torturous hell of a journey for many, leaving them in anticipation of what's ahead, and this particular composition left me a little bit of the feeling.Three's A CompanyI was aiming for shooting the ambiance created by afternoon lights peeking through the clouds and along came these three motorcyclists. I was walking and they were moving through, and luckily my hands were fast enough to half-click the shutter and expect them to come in this formation before they all exit the junction, and their movement, and regularity were thus frozen forever in time.And my favorite amongst them allThe Daily ConfrontationI have always liked to capture the life of everyday working people, whenever I'm on the shuttlebus or just in the commuter cars seen in this picture, I've always been imagining myself capturing the moment, to spill it out later when I have the time (and the urge) to work it on my canvas. 5 years later, when my brush is all dry and I still can't bring myself to take all those toxic paints into my small habitat, I finally got myself a camera, and when I brought it to this trip here, I was blessed with my favorite lighting. The contrast and bluish hue brought in by the foggy sky and the reflecting surfaces made by rain water just after a rain is just beautiful and within this perfect environment, I found this gem.all except for the \"Three's A Company\" were shot from inside a shuttlebus, and I was lucky enough to have the front seat available and yes the distortions which came from the wet windscreen are particularly pleasing for me. I tried to as much as possible to shoot at aperture wide open and minimal zoom, to maximize my camera's potential, since it doesn't have a fancy APS-C sized sensor.

More than 4 modules per mars transfer would be painful.Dilemma:I would like the technology to be closer to todays reality, but I can see that this would also prevent many less than advanced players from taking part. So, I would suggest that a DG-Tech Mars vehicle would be better. A NERVA looks good, but is maybe already too hard for some.A program patch would be nice, but is currently the most useless thing in the queue. We need to get things started so the program is running, and then, when all the dangerous decisions are behind us, we can talk again about the decorations.Instead of many people talking endlessly against each other, there should be a direction. So, let me suggest a very simple method of making sure work gets done, instead of just talking about it: Delegate responsibility. We have heard enough opinions now, and I think we all agree that this is a great forum project. Now, the talking can cease, and the metal has to be cut.Before we decide on which vehicle we use, we should know what the vehicle(s) will transport. Thus, I think the task for the weekend should be: \"Plan how the first Mars expedition should look like, how many consumables they need to survive there, and how it can get transported\". This includes making suggestions how the mars base will look like in the first 18 months or how it evolves in that time.Remember: There will be a few weeks of an open launch window on Mars, that permits us to transport material there and let spacecraft directly fly back to Earth before the return window closes for 18 months. After it closes, the permanent expedition crew that is left on Mars will have to survive on what is on Mars, no resupplies possible. And I am sure, we want to call such a thing a base and not a tent city for some days before all go away for months.I am also sure, we don't want to fast forward until the Earth-Mars window opens again. So, we need so meaningful missions on Earth and Mars that fill the gap.We also need to decide first, how the crew gets to Mars and how they leave it: On the same vehicle as they used for landing (Apollo like) or use a Earth Return Vehicle (Like Mars Direct)? Swap spacecraft or not? Mars Orbit Rendezvous?For not loosing the paperwork in Forum&Social Groups, let me suggest (like always) to use OrbiterWiki for gathering the important information.

How do you get a fueled SRB into orbit?2. SRB has a way low Isp, 269 -means it burns through a ton of fuel much faster than a higher Isp engine would, which in this case Nerva has is ~1800.

Yes, I say that as role-playing game fanatic. What would be needed one day would be a fuel station in Mars orbit, that is right (Unless in-situ fails). But if you plan to assemble this one first and then from time to time do flags and footprints, you are on the road to hell. A Mars space station will need water, food and fuel, and the best place to get this would be the surface of Mars.\n\nThing is, we were going to build it in LEO, so we could move it to Mars without sucking up all of our launch window. I never implied that we would sit up on orbit and every now and again go and plant some flags. I have always seen it has having the MSS in addition to all of our ground operations. I have not seen it stated otherwise.Urwumpe said:I won't do flags and footprints, I want the full package. And I also won't do a OFSS in Mars orbit only for pleasing under-performers. I can already see Space station modules being lost in space, because people suddenly realize that they failed the Mars orbit insertion and can't correct the orbit plane. It sounds all easy if it is not you who has to do it. A mars surface base has the tiny advantage that you need to wait maximal 12 hours before you get the next chance for landing nearby.\n\nI agree, I don't want to just do flags and footprints either. Personally, I'm excited for us to go out find resources, gather them, handle the logistics and such, definitely the best part. As for missing an orbit insertion and you gave as an example: that would also include getting any ship into Mars orbit, be it MSS modules or not. Obviously people who couldn't get into the proper orbit wouldn't fly those missions. We have plenty of people wanting to fly missions, and I am sure we will find people who can fly the more advanced flights.Urwumpe said:I disagree strongly. And if you have been to Mars, did you ever try landing precisely? Or why are you talking like building a *garble* space station in Mars orbit is the best of the world? A space station can also be done ourselves individually... how impressive. Doing five Mars transfer missions in one window, while you also do surface operations, that needs workforce, because juggling five balls alone is already hard enough, than to also do this while vacuum cleaning your kitchen floor.\n\nI have been to Mars, and yes I did precision landings. I don't see why you have to doubt me without cause, I have no reason to say it if it wasnt true. I also know we can do stations individually too, and I know it is not particularly impressive.

The results were published today in Science as one article in a five-paper special section on the Curiosity mission.\"One of the most exciting results from this very first solid sample ingested by Curiosity is the high percentage of water in the soil,\" said Laurie Leshin, lead author of one paper and dean of the School Science at Rensselaer Polytechnic Institute. \"About 2 percent of the soil on the surface of Mars is made up of water, which is a great resource, and interesting scientifically.\" The sample also released significant carbon dioxide, oxygen and sulfur compounds when heated.Curiosity landed in Gale Crater on the surface of Mars on Aug. 6, 2012, charged with answering the question: \"Could Mars have once harbored life?\" To do that, Curiosity is the first rover on Mars to carry equipment for gathering and processing samples of rock and soil. One of those instruments was employed in the current research: the Sample Analysis at Mars (SAM) instrument suite, which includes a gas chromatograph, a mass spectrometer and a tunable laser spectrometer. These tools enable SAM to identify a wide range of chemical compounds and determine the ratios of different isotopes of key elements.\"This work not only demonstrates that SAM is working beautifully on Mars, but also shows how SAM fits into Curiosity's powerful and comprehensive suite of scientific instruments,\" said Paul Mahaffy, principal investigator for SAM at NASA's Goddard Space Flight Center in Greenbelt, Md. \"By combining analyses of water and other volatiles from SAM with mineralogical, chemical and geological data from Curiosity's other instruments, we have the most comprehensive information ever obtained on Martian surface fines. These data greatly advance our understanding surface processes and the action of water on Mars.\"Thirty-four researchers, all members of the Mars Science Laboratory Science Team, contributed to the paper.In this study, scientists used the rover's scoop to collect dust, dirt and finely grained soil from a sandy patch known as Rocknest. Researchers fed portions of the fifth scoop into SAM. Inside SAM, the \"fines\"\u2014the dust, dirt and fine soil\u2014were heated to 1,535 degrees F (835 C).Baking the sample also revealed a compound containing chlorine and oxygen, likely chlorate or perchlorate, previously found near the north pole on Mars. Finding such compounds at Curiosity's equatorial site suggests they could be distributed more globally. The analysis also suggests the presence of carbonate materials, which form in the presence of water.In addition to determining the amount of the major gases released, SAM also analyzed ratios of isotopes of hydrogen and carbon in the released water and carbon dioxide. Isotopes are variants of the same chemical element with different numbers of neutrons, and therefore different atomic weights. SAM found that the ratio of some isotopes in the soil is similar to the ratio found in atmospheric samples analyzed earlier, indicating that the surface soil has interacted heavily with the atmosphere.\"The isotopic ratios, including hydrogen-to-deuterium ratios and carbon isotopes, tend to support the idea that as the dust is moving around the planet, it's reacting with some of the gases from the atmosphere,\" Leshin said.{colsp=2}Click on images for details\u200b|The Sample Analysis at Mars instrument suite, prior to its installation on the Curiosity rover.Image Credit: NASA Goddard\u200b|The Sample Analysis at Mars instrument suite found water in the dust, dirt and fine soil from the Rocknest site on Mars. (This file photo shows trenches Curiosity dug in October 2012.)Image Credit: NASA\/JPL-Caltech\/MSSS\u200bSAM can also search for trace levels of organic compounds. Although several simple organic compounds were detected in the experiments at Rocknest, they aren't clearly Martian in origin. Instead, it is likely that they formed during the high-temperature experiments, when the heat decomposed perchlorates in the Rocknest samples, releasing oxygen and chlorine that then reacted with terrestrial organics already present in the SAM instrument.A related paper, published in the Journal of Geophysical Research-Planets, details the findings of perchlorates and other chlorine-bearing compounds in the Rocknest sample. This paper is led by Daniel Glavin, a Mars Science Laboratory Science Team member at Goddard.Glavin notes that SAM has the ability to perform another kind of experiment to address the question of whether organic molecules are present in the Martian samples. The SAM suite includes nine fluid-filled cups which hold chemicals that can react with organic molecules if present in the soil samples. \"Because these reactions occur at low temperatures, the presence of perchlorates will not inhibit the detection of Martian organic compounds,\" said Glavin.The combined results shed light on the composition of the planet's surface, while offering direction for future research.\"Mars has kind of a global layer, a layer of surface soil that has been mixed and distributed by frequent dust storms. So a scoop of this stuff is basically a microscopic Mars rock collection,\" said Leshin. \"If you mix many grains of it together, you probably have an accurate picture of typical Martian crust. By learning about it in any one place you're learning about the entire planet.\"{...}NASA JPL\/ NASA:Science Gains From Diverse Landing Area of CuriositySept 26, 2013PASADENA, Calif. -- NASA's Curiosity rover is revealing a great deal about Mars, from long-ago processes in its interior to the current interaction between the Martian surface and atmosphere.Examination of loose rocks, sand and dust has provided new understanding of the local and global processes on Mars. Analysis of observations and measurements by the rover's science instruments during the first four months after the August 2012 landing are detailed in five reports in the Sept. 27 edition of the journal Science.A key finding is that water molecules are bound to fine-grained soil particles, accounting for about 2 percent of the particles' weight at Gale Crater where Curiosity landed. This result has global implications, because these materials are likely distributed around the Red Planet.Curiosity also has completed the first comprehensive mineralogical analysis on another planet using a standard laboratory method for identifying minerals on Earth. The findings about both crystalline and non-crystalline components in soil provide clues to the planet's volcanic history.Information about the evolution of the Martian crust and deeper regions within the planet comes from Curiosity's mineralogical analysis of a football-size igneous rock called \"Jake M.\" Igneous rocks form by cooling molten material that originated well beneath the crust. The chemical compositions of the rocks can be used to infer the thermal, pressure and chemical conditions under which they crystallized.\"No other Martian rock is so similar to terrestrial igneous rocks,\" said Edward Stolper of the California Institute of Technology, lead author of a report about this analysis. \"This is surprising because previously studied igneous rocks from Mars differ substantially from terrestrial rocks and from Jake M.\"The other four reports include analysis of the composition and formation process of a windblown drift of sand and dust, by David Blake of NASA's Ames Research Center at Moffett Field, Calif., and co-authors.Curiosity examined this drift, called Rocknest, with five instruments, preforming an onboard laboratory analysis of samples scooped up from the Martian surface. The drift has a complex history and includes sand particles with local origins, as well as finer particles that sample windblown Martian dust distributed regionally or even globally.{colsp=3}Click on images for details\u200b||Target: Jake Matijevic Rock\u200bThis image shows where NASA's Curiosity rover aimed two different instruments to study a rock known as \"Jake Matijevic.\"Image Credit: NASA\/JPL-Caltech\/MSSS\u200b|Curiosity's First Scoop of Mars, in Vibration Movie\u200bThis video clip shows the first Martian material collected by the scoop on the robotic arm of NASA's Mars rover Curiosity, being vibrated inside the scoop after it was lifted from the ground.Image Credit: NASA\/JPL-Caltech\/MSSS\u200b|Curiosity's Location During First Scooping\u200bThis 360-degree scene shows the surroundings of the location where NASA's Mars rover Curiosity arrived on the 59th Martian day, or sol, of the rover's mission on Mars (Oct. 5, 2012).Image Credit: NASA\/JPL-Caltech\u200bThe rover is equipped with a laser instrument to determine material compositions from some distance away. This instrument found that the fine-particle component in the Rocknest drift matches the composition of windblown dust and contains water molecules. The rover tested 139 soil targets at Rocknest and elsewhere during the mission's first three months and detected hydrogen -- which scientists interpret as water -- every time the laser hit fine-particle material.\"The fine-grain component of the soil has a similar composition to the dust distributed all around Mars, and now we know more about its hydration and composition than ever before,\" said Pierre-Yves Meslin of the Institut de Recherche en Astrophysique et Plan\u00e9tologie in Toulouse, France, lead author of a report about the laser instrument results.A laboratory inside Curiosity used X-rays to determine the composition of Rocknest samples. This technique, discovered in 1912, is a laboratory standard for mineral identification on Earth. The equipment was miniaturized to fit on the spacecraft that carried Curiosity to Mars, and this has yielded spinoff benefits for similar portable devices used on Earth. David Bish of Indiana University in Bloomington co-authored a report about how this technique was used and its results at Rocknest.X-ray analysis not only identified 10 distinct minerals, but also found an unexpectedly large portion of the Rocknest composition is amorphous ingredients, rather than crystalline minerals. Amorphous materials, similar to glassy substances, are a component of some volcanic deposits on Earth.Another laboratory instrument identified chemicals and isotopes in gases released by heating the Rocknest soil in a tiny oven. Isotopes are variants of the same element with different atomic weights. These tests found water makes up about 2 percent of the soil, and the water molecules are bound to the amorphous materials in the soil.\"The ratio of hydrogen isotopes in water released from baked samples of Rocknest soil indicates the water molecules attached to soil particles come from interaction with the modern atmosphere,\" said Laurie Leshin of Rensselaer Polytechnic Institute in Troy, N.Y., lead author of a report about analysis with the baking instrument.Baking and analyzing the Rocknest sample also revealed a compound with chlorine and oxygen, likely chlorate or perchlorate, which previously was known to exist on Mars only at one high-latitude site. This finding at Curiosity's equatorial site suggests more global distribution.Data obtained from Curiosity since the first four months of the rover's mission on Mars are still being analyzed. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, Calif., manages the mission for NASA's Science Mission Directorate in Washington. The mission draws upon international collaboration, including key instrument contributions from Canada, Spain, Russia and France.{...}Discovery News:This Scoop of Mars Soil is Two Percent WaterWater Discovery Is Good News for Mars ColonistsPhys.org:'Jake_M': Unusual Mars rock describedMars rover Curiosity finds water in first sample of planet surfaceMartian chemical complicates hunt for life's cluesScience benefits from diverse landing area of NASA mars roverWater for future Mars astronauts?

Just remember that you don't want to kill your project before it has started - keep the initial project goals simple and easy to achieve. Once you build up something with a bit of momentum, then start with the more ambitious tasks of making your own modules and whatnot. I worry that if it takes too long to get off the ground in Orbiter, the project will never get off the ground at all....Good luck!\n\nIf we where really to go to Mars we would need to bring the necessary stuff, otherwise that 18 month for a round trip from Arrows resupply is a long wait. Besides, I don't think its really that much work to make these few objects we need. Thankfully with the help of UCGO and SC3, this should be up and running fairly quickly. We just need a few meshes and some config's made.Izack said:Arrowstar has a point...Why just do the reskinning for the XR\/DGs and then start construction right away? As we build we can plan the actual flight. Also, just browsing through Orbithangar I've found that we already have enough stuff for a pretty interesting Mars mission.As for texturing, Orbiter uses DDS format for its vessels, right? I'm sure there's a GIMP plugin for that, if it can't do it already. I'll seeNow to bring up a little idea...I've been looking around this site for a while now, and I keep finding these old threads about a multiplayer aspect of Orbiter. If anyone remembers how to do this, is it possible to set up a dedicated realtime server? This is probablywaytoo ambitious looking at what's being said now, and perhaps also impractical for a lot of people here.\n\nOMPOMP works, though a little buggy last I knew, but the only times I can see where it would be really useful, is while loading and unloading cargo. Otherwise, its really only the pilots running at their times. In that instance, it would be extremely useful. Though I rather lack knowledge in using OMP.Wolfer said:Well I was thinking more about something likethis.\n\nMy thought exactly. Would look great for the Martian cargo lander.

For example, if one were to use the exact same technological requirements (for propulsion, structure, TPS, etc) for a TSTO as one were an SSTO, then a higher operating and development costs for the former could indeed make sense.The key is that a TSTO, not having the same physical requirements as an SSTO, does not need to have the same technological requirements as well. By having more physical leeway in a TSTO design, you can use methods and techniques that are cheaper. And yes, you will have extra recovery\/integration costs, and costs for the development of seperate stages... but the less demanding technology overall makes up for it.And a TSTO need not have as much dissimilarity between the stages as you might imagine. There are lots of solutions that can potentially be employed- including near-identical stages (think shades of bimese\/triamese).In this respect, a TSTO is far more related to a \"designing for cost\" approach than anything you are suggesting.

First of all, it assumes that Kardashev II technology would make those that possess it more intellegent. This is by no means a given. For all our wonderful technology, we aren't any smarter than we were one or two or ten thousand years ago.Secondly, if we take the assumption that they are smarter, it also assumes that just because these hypothetical Kardashev II aliens are to us as we are to ants, they will be as aware of us as we are of ants. There are two problems here:1) That the Kardashev II civ will have historical records of having been a civilization on our level (we have no historical records of being ants), and will thus have more first-hand experience of how things are for civs on our level than we have for \"ant civilization\".2) That the greater intelligence of the Kardashev II civilization might just make them more aware of ants than we are, and correspondingly more aware of us. We might not care about running over an anthill, they might. (Now this does not necessarily mean that their treatment of anthills, or of us, would be benevolent, just that there would be more thought put into it.

Your creative ideas are all but worthless in the face of vastly superior intelligence.\n\nHere again is the assumption that superior technology means superior intellect. It does not.

However, SpaceX wants to transition to reusables. Elon has stated this will result in a surprisingly high loss of payload of 40% for the fully reusable case. A big part of this is due to the need to return the first stage, which doesn't reach orbit, to the launch site.This doesn't hold for the single stage case, resulting in a much smaller loss of payload. The result is the increase in payload of a fully reusable two stage is not nearly as large over a reusable single stage.

I hate incompetence.Second, your \"authorities\" are:Henry Spencer: Famous computer programmer, newsgroup activist and space enthusiast. He has NEVER worked for a spaceflight company, but is active in the Canadian Space Society. He is no professional however, just a very good amateur - we have dozens of those in the Orbiter community.Mitchell B Clapp: Inventor, book author, former USAF captain, military scientist\/engineer - holds two patents on rocket planes, space enthusiast, had been supporting the failed Rocketplane Limited in 1997. Was employed at the Phillips Laboratory, before he joined Rocketplane Limited, today the Phillips Laboratory is split into the Space Vehicles and Directed Energy Directorates of the Airforce Research Laboratory. Was last employed the at the VT-X, the Launch Vehicle Technology Office. Nothing known about his life since 1999.Notice something?Also, if I remember the newsgroup discussion between the two, that you treat here like a scientific publication, correctly, Clapp did actually correct Spencer a few times, but also based his findings on the Trident 2 missile, which is having a too high acceleration for any kind of payload that isn't a warhead.PS: For all those people that never heard of the ascent equation and are maybe feeling as surprised as Spencer:[math]\\Delta v = \\Delta v^{\\ast} - \\mu \\int_0^{t_b} \\frac{\\cos {\\alpha}}{r^2} \\mathrm{d}t - \\int_0^{t_b}\\frac{D}{m} \\mathrm{d}t - \\int_0^{t_b} \\frac{F}{m} \\left ( 1 - \\cos{\\delta} \\right ) \\mathrm{d}t[\/math][math]\\Delta v[\/math] is the velocity change between ground velocity and orbital velocity[math]\\Delta v^{\\ast}[\/math] is the total velocity change as produced by the engines and calculated by the rocket equation[math]t_b[\/math] is the burn out time, the moment you reach orbit[math]\\alpha[\/math] is the flight path angle (0\u00b0 = straight up)D is the drag forcem is massF is the engine thrust[math]\\delta[\/math] is the steering angle, the angle between total thrust vector and velocity vector.Thus, the first integral are the gravity losses, the second the aerodynamic losses and the third the control losses.As you can easily see - the smaller the [math]t_b[\/math], the lower the losses.(Yes, I finally had the time to hack this into Latex form)", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.580619776Z", "author": "RGClark", "date": "2011-07-05T22:17:36+0100", "id": "7451f85d515b5b9766cd19379bcb8ea9", "post_id": "post-220180", "text": "Urwumpe said:...The SSTO will reach the following payload mass ratio at a structural mass fraction of 0.05 and an specific impulse of 3300 m\/s:[math]\\lambda_{SSTO} = \\frac{e^{\\frac{-9200 \\frac{m}{s}}{3300 \\frac{m}{s}}} - 0.05} {1 - 0.05} = 0.0122[\/math]Just 1.22% of the mass will be available for payload (and any advanced recovery and landing systems, if desired)The TSTO will at equal parameters and approximately optimized stage ratio get:[math]\\lambda_{TSTO} = \\left (\\frac{e^{\\frac{-4600 \\frac{m}{s}}{3300 \\frac{m}{s}}} - 0.05} {1 - 0.05} \\right ) ^2 = 0.0435[\/math]That means 4.35% of the lift off mass will be available for payload. The SSTO will weight 3.57 times more for the same payload as the TSTO. That is about the difference between Soyuz and Space Shuttle.\n\nThanks for the calculation.It is averyimportant point to keep in mind that dense propellant SSTO's actually require less delta-V to orbit than hydrogen fueled SSTO's. This is trueeven whenthe two cases have the same liftoff T\/W ratio.See the discussion here:Hydrogen delta-V (Henry Spencer; Mitchell Burnside Clapp).The bottom line, when all this converges -- including a small gain fromlower drag on a more compact vehicle, and a very small bonus from lowerdrag making the acceleration still higher -- is that a standard orthodoxNASA LOX\/LH2 SSTO needs 31000ft\/s to reach the space-station orbit, and an H2O2\/kerosene SSTO needs only 29050ft\/s.(In fact, the explanation came after the numbers -- when good trajectorysimulations kept coming out with lower delta-Vs for H2O2\/kerosene, Mitchdecided he had to understand what was going on.)Now, consider. The H2O2\/kerosene SSTO is operating in a very steep partof the mass-ratio curve. A 6% saving in delta-V is *not* trivial. Forengines with a vacuum Isp of 320, the required mass ratio drops from 20 to16. Given the aforementioned sophisticated scaling models, at this massratio, the H2O2\/kerosene SSTO's payload at the same GLOM is now equal to that of the LOX\/LH2 design.So the dense-fuel SSTO has lower dry mass, smaller vehicle size, cheaperand easier-to-handle propellants, and now suffers no GLOM penalty... Justwhat was the advantage of LOX\/LH2 supposed to be again?http:\/\/yarchive.net\/space\/rocket\/fuels\/hydrogen_deltav.htmlFor a kerosene fueled SSTO the delta-V to orbit is often taken as 8,900 m\/s. To do a simple calculation, I'll use some estimated numbers for the Falcon 9 first stage: a dry mass of 15,000 kg and a propellant mass of 285,000 kg, to give a mass ratio of 20 to 1. Let's suppose we swapped out the low efficiency Merlin engines for an engine with an Isp of 3,300 m\/s. Then we could get 5,600 kg payload:3,300ln(1+285\/(15+5.6)) = 8,900 m\/s.This is a payload fraction of 5.6\/(300+5.6) = .0183, or 1.8%. It is indeed true though that SSTO's are best used as reusable. I gave an estimate before that perhaps 28% of the landed mass has to be set aside for reentry\/landing systems. However, with modern materials such as composites quite likely less than half this would be required. So .14*15,000 kg = 2,100 kg for the R\/L systems. This gives us 3,500 kg left over for payload.Since this is to be a reusable system we would need the maintenance costs to be kept minimal. The big focus of X-33\/VentureStar program was to cut support staff by two orders of magnitude over that of the shuttle, from literally ten's of thousands to a few hundred. Also, the engines and thermal protection system were designed to require minimal maintenance between flights. If you suppose then the reusable kerosene engines used could manage 100 flights, then this could indeed cut the costs to orbit significantly.Another factor to keep in mind though is that payload fraction really is not a good measure, figure of merit, to use to measure the efficiency of a launch system. The reason is that the cost of the propellant is a trivial component to the cost of the launch but makes up the great majority of the mass you're comparing the payload to in calculating the payload fraction.Many in the industry now say a much better measure would be to compare the payload to the dry mass, as this much better tracks the cost of the vehicle. The dry mass remember is the stuff that actually has to be constructed and tested.For this SSTO, this payload to dry mass ratio, for the expendable case to make an apple to apples comparison, is 5.6\/15 = 0.37, 37%.What is it for the TSTO case you are considering?Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.613547008Z", "author": "Sky Captain", "date": "2010-09-18T09:46:03+0100", "id": "e25ba64e15b51849da6bd54513da2070", "post_id": "post-252996", "text": "That is behind my idea to create a ghost vessel with very strong RCS to have 2 RCS modes one strong and one weak.

There is more to a DSLR than its mirror and viewfinder. While smaller cameras have to rely on a contrast detection system for autofocus, DSLRs have a more accurate and faster phase detection system. There's an explanationhere.The performance of ILCs are improving and closing the gap, but they also fall behind DSLRs in burst shooting, weather sealing, and battery life. It's also easier to fit a larger sensor into a bigger SLR body, which results in better image quality. DSLRs have a bigger lens selection, and the bigger lenses are superior because they can hold more elements, have longer focal lengths and wider apertures.There is definitely a place for DSLRs, but most people don't require that kind of performance.In comparison, iPhones and other smartphones have miniscule sensors which cannot come near to matching the light sensitivity and image quality of a simply larger piece of silicon. It's also very difficult to generate a thin depth of field with a smaller light collecting area, and impossible with the tiny lenses on smartphones unless the subject is very close.Point-and-shoots (or compact cameras) have made giant gains in sensor size recently because camera companies have to compete with smartphones. So the performance of some compact cameras are far better than smartphones, but they still don't match cameras with changeable lenses. However, compacts areapproacingthat kind ofperformance.Most photographs I take now are with the original Sony RX100, one of the first cameras to fit a large sensor into a tiny body. The image quality from that little compact is close to a DSLR, but it lacks the lenses, battery life, depth of field control, and performance.Smartphone:http:\/\/fav.me\/d7zlkug2008 point-and-shoot:http:\/\/fav.me\/d6oz6fz2012 point-and-shoot:http:\/\/fav.me\/d85jzpjDSLR (shallow DoF):http:\/\/fav.me\/d4u0yn0DSLR (wide DoF):http:\/\/fav.me\/d6eadg2", "thread_id": 14022 }, { "@timestamp": "2023-09-14T07:13:36.441302528Z", "author": "bpops", "date": "2010-09-14T22:27:39+0100", "id": "b2b46d74b02b7dc8e1f10498d27d4029", "post_id": "post-252570", "text": "I'm a little late to this party, but thanks Martin on the latest update.:thumbup:", "thread_id": 16306 }, { "@timestamp": "2023-09-14T07:13:05.615726592Z", "author": "Pablo49", "date": "2010-05-08T04:57:12+0100", "id": "9fa3d76ef3d444e7f314fad2f3c008e0", "post_id": "post-220745", "text": "supersonic said:I would like to fly assembly flights, after thats done dock to the main ship and put my ship in the hands of the person flying the stack until we get to Mars.

We have been to the Cosmodrome togther and when we were inspecting the launch sites, she explained that to me very simply: when we, the humans think about what is going to happen to Earth in the near future, we can't wave off the problems like asteroids flying in our direction, meteorite showers and other factors that influence our civilization.\"\"From my standpoint, I shall note that the threat of an asteroid coming down on us is real. There are several programs developed by space agencies and offered to the international community on how we can avoid the real threat of obliterating our civilization on Earth. Also there are certain plans on settlement on the Moon by making there livable clusters, and even plans for manned flights to Mars.\"\"These topics are of great interest for Anna Vasilyevna. She is researching them for a long time. In particular, her project is connected with finding a way to compensate for that worrying asteroid situation with minimal losses and how humanity can develop if we have to use Earth's orbit for resisting these phenomenae. That's also about how we can use international space stations and international collaboration. In her work she models different situations.\"Rep: \"How long ago Anna took this up?\"CEO: \"In depth, no less than a year ago, as I can judge by her project\"Rep: \"It sounds like a science fiction, doesn't it?\"CEO: \"Every situational modeling is fictional by nature. But this is a fiction based on a precise calculation and pragmatic analysis of the situation.\"Rep: \"And how about PR plugging activity?\"CEO: \"I find it ridiculous to plug an asteroid that's on collision course with Earth. But if you regard PR a system to inform society, then we probably do just that.\"\n\nAnd finally, some guys impressed by the startling news about Anna's new activities, decided to promote her bursting into blossom career with a littleflash game called SuperAnna:http:\/\/marker.ru\/interactive\/superannaAs it is not localized to English, I'll explain few things.To begin playing, click on \u0421\u041f\u0410\u0421\u0422\u0418 \u041f\u041b\u0410\u041d\u0415\u0422\u0423 flashing title.Your goal is to earn as much\u20b1's for Anna as possible.To do that, you must shoot down unfriendly objects and avoid shooting friendly ones.

The car-sized rover will arrive closer to its ultimate destination for science operations, but also closer to the foot of a mountain slope that poses a landing hazard.\"We're trimming the distance we'll have to drive after landing by almost half,\" said Pete Theisinger, Mars Science Laboratory project manager at NASA's Jet Propulsion Laboratory in Pasadena, Calif. \"That could get us to the mountain months earlier.\"It was possible to adjust landing plans because of increased confidence in precision landing technology aboard the Mars Science Laboratory spacecraft, which is carrying the Curiosity rover. That spacecraft can aim closer without hitting Mount Sharp at the center of Gale crater. Rock layers located in the mountain are the prime location for research with the rover.{colsp=3}Click on images for details\u200b||This image shows changes in the target landing area for Curiosity, the rover of NASA's Mars Science Laboratory project.

Following checkout operations, Curiosity will begin a two-year study of whether the landing vicinity ever offered an environment favorable for microbial life.Theisinger and other mission leaders described the target adjustment during an update to reporters on Monday, June 11, about preparations for landing and for operating Curiosity on Mars.The landing target ellipse had been approximately 12 miles wide and 16 miles long (20 kilometers by 25 kilometers). Continuing analysis of the new landing system's capabilities has allowed mission planners to shrink the area to approximately 4 miles wide and 12 miles long (7 kilometers by 20 kilometers), assuming winds and other atmospheric conditions are as predicted.Even with the smaller ellipse, Curiosity will be able to touch down at a safe distance from steep slopes at the edge of Mount Sharp.\"We have been preparing for years for a successful landing by Curiosity, and all signs are good,\" said Dave Lavery, Mars Science Laboratory program executive at NASA. \"However, landing on Mars always carries risks, so success is not guaranteed. Once on the ground we'll proceed carefully. We have plenty of time since Curiosity is not as life-limited as the approximate 90-day missions like NASA's Mars Exploration Rovers and the Phoenix lander.\"Since the spacecraft was launched in November 2011, engineers have continued testing and improving its landing software. Mars Science Laboratory will use an upgraded version of flight software installed on its computers during the past two weeks. Additional upgrades for Mars surface operations will be sent to the rover about a week after landing.Other preparations include upgrades to the rover's software and understanding effects of debris coming from the drill the rover will use to collect samples from rocks on Mars. Experiments at JPL indicate that Teflon from the drill could mix with the powdered samples. Testing will continue past landing with copies of the drill. The rover will deliver the samples to onboard instruments that can identify mineral and chemical ingredients.\"The material from the drill could complicate, but will not prevent analysis of carbon content in rocks by one of the rover's 10 instruments. There are workarounds,\" said John Grotzinger, the mission's project scientist at the California Institute of Technology in Pasadena. \"Organic carbon compounds in an environment are one prerequisite for life. We know meteorites deliver non-biological organic carbon to Mars, but not whether it persists near the surface. We will be checking for that and for other chemical and mineral clues about habitability.\"Curiosity will be in good company as it nears landing. Two NASA Mars orbiters, along with a European Space Agency orbiter, will be in position to listen to radio transmissions as Mars Science Laboratory descends through Mars' atmosphere.{...}NASA Press Release:RELEASE : 12-192 - NASA Mars Rover Team Aims for Landing Closer to Prime Science SiteSPACE.com:Huge Mars Rover Faces Contamination Issue Ahead of August LandingCBS News Space:Mars Science Lab rover on track for August descent to red planetUniverse Today:Engineers Able to Narrow Landing Ellipse for Curiosity RoverDiscovery News:Mars Rover Now Aiming for Sweet SpotFlorida Today:NASA's Curiosity rover eyes closer landing to targetNASA's Discovery rover zeroing in on Mars crater landing", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:04.958134272Z", "author": "Andy44", "date": "2010-05-17T20:39:59+0100", "id": "21e06ef893d1c58539e78d73c407c022", "post_id": "post-219499", "text": "Anybody here ever try using or making your own pinhole camera?

I guess I should not have been surprised by this. The thesis I have been arguing repeatedly via email with individuals in NASA and the industry and on space forums such as this one is that if you use BOTH the most weight optimized designs AND the highest efficiency engines available, then what you will wind up with will be SSTO capable whether you intend it to or not.By highest efficiency engines I don't mean just an engine optimized to have a high vacuum Isp only. I mean an engine of highest efficiency over the entire flight range to orbit. For hydrogen engines that is the SSME, and the Russian analogue RD-0120...\n\nAnother highly weight optimized stage was the S-II second stage on the Saturn V. According to this Wikipedia page it was even better optimized than the S-IVB stage :Saturn V.S-II second stage.http:\/\/en.wikipedia.org\/wiki\/Saturn_V#S-II_second_stageThe 5J-2 enginesused had a mass of 1,580 kg each, for a total mass of 7,900 kg. You'll need 3 of the SSME'soperating at 109% thrustto lift the mass. So the 7,900 kg mass of the engines is replaced with 9,300 kg. And the 36,000 kg S-II dry mass is raised to 37,400 kg and the gross mass is raised to 481,400 kg.Now usingGary Hudson's 425s trajectory averaged Isp for the SSME engines, and the 9,200 m\/s required delta-V to orbit. We get a 17,000 kg payload:425*9.8ln((481400 + 17000)\/(37400 + 17000)) = 9,225 m\/sHowever, again we can get 10% greater total mass to orbit by propellant densification. This brings the payload to 22,440 kg. Also perhaps 10% off the structural mass can be saved by using aluminum-lithium alloy. And an additional 10% mass can be saved by the new weight saving methods. These weight savings can go to extra payload to bring the payload mass up to 28,000 kg.

Elon has said the Merlin should be reusable ten's of times.\n\nEstimates of Elon Musk impress me not at all - when he did so, I am impressed. Until that day, I have to assume that all he does is cooking with water like all the others. And is using cheaper, low technology gas generator cycle engines that can have a pretty long run time, but are no magic at all. They still run very hot, need expensive checks after each burn if you for example test them on the ground and can still explode if you mistreat them. Actually all photo and video evidence of the launches, which is the most solid evidence you have from SpaceX, since they keep most of the technical data of their launchers secret (for a reason), show no especially advanced launcher, just a company that applies Russian quality assurance on western technology (which is in case of SpaceX, using the worst of both worlds, since Russian rocket engines are much more advanced as the stuff they build).Also, if you can reuse your rocket engines 20 times, this does not make the rocket 20 times cheaper. And especially not the launch.The figure for NASA is like that: They pay 1.6 billion USD for 12 Falcon 9\/Dragon flights. That means 133 million per flight. That is in the same range as you pay for a Ariane 5 flight and 50% cheaper than an EELV flight. Worlds apart from the $100 per kg that you advocate by faith.Each Falcon 9 can haul 9,500 kg into space, this means every flight like that costs $14000 per kg - not even the $6000 that are accepted as low technological risk today. There is no number known about the launch costs without a dragon, and especially no number that is really business as usual.The estimates by SpaceX for the Falcon 9 without Dragon (not confirmed by any customer contract yet) are 35 million USD. That is $3600\/kg - a great number, right in the Russian price range. But not especially cheap.The lowest estimate by Spacex for the Falcon 9\/Heavy is 78 million with 24500 kg payload: $3200 kg. Conservative optimistic estimates from real engineers go to 120 million which is 50% higher, but more realistic, making the Falcon 9\/Heavy a whole lot cheaper as the current Ariane 5, with better performance, but that is still a number that has to be achieved first.Notice something?What SpaceX promises in their marketing mode, and what they really charge as price, are not the same at all.If you assume, SpaceX manages to (magically) reduce the costs by 5% every year (a pretty good value, it means it gets cheaper despite inflation), SpaceX would need 137 years to get that low.

So it's not just a matter of density of the propellant since you actually have more volume to hold the propellant.Bob Clark\n\nI just saw this on Hobbyspace.com:Boeing proposes SSTO system for AF RBS program.The new issue of Aviation Week has a brief blurb about a Boeing proposal for the Air Force's Reusable Booster System (RBS) program: Boeing Offers AFRL Reusable Booster Proposal - AvWeek - June.13.11 (subscription required).Darryl Davis, who leads Boeing's Phantom Works, tells AvWeek that they are proposing a 3-4 year technology readiness assessment that would lead up to a demonstration of a X-37B type of systembut would be smaller. Wind tunnel tests have been completed. Davis says the system would be a single stage capable of reaching low Earth orbit and, with a booster, higher orbits. The system would return to Earth as a glider.Davis says \"that advances in lightweight composites warrant another look\" at single-stage-to-orbit launchers.http:\/\/www.hobbyspace.com\/nucleus\/index.php?itemid=30110I don't have a subscription to AV Week.

Despite all attempts of the younger engineers and technicians, nothing worked, and the alternative started to become buying a new machine for a few million Euro. The owner of the company saw the proposed solution and was not willed to get deeply in debts without fighting, so he called the retired engineer, if he couldn't do anything there.The engineer arrived, looked a few minutes at everything, measured a few things, pushed against some parts and then marked a part of the machine with chalk and said \"Replace this axle and all will be fine again\". The technicians did as told, and suddenly, the machine was running as good as a new one.The engineer went to his former employer, and produced a bill over 10,000 Euro for his work. The company owner was surprised, after all, he didn't do anything except making a chalk mark. The engineer explained the bill in detail:Chalk - 1\u20acKnowing where to put the mark - 9,999\u20acNow the company owner was enlightened and paid the bill.Experience and skills together are extremely rare and extremely valuable. And they define their price.Also, you have to look at the physical aspects there: The more performance you want, the less tolerances for errors you get. Performance is not just brute force alone, but also effectivity. The more effective your spacecraft should get, the more effective have its parts to get. The whole is maybe more than just the sum of all parts, but still you can't use junk parts alone with only junk skills of your engineers.The math is pretty simple there: The less chamber pressure you have available, the less effective your rocket will be because the exhaust has less energy per kg. At the same time, a higher pressure means a lighter rocket engine for the same thrust. without pumps, you can't get very high chamber pressures, you are limited by the tank pressure and the structural mass.For anything worth talking as SSTO or TSTO, you will need pumps, simply because the limitations of pressure-fed will be ugly. for pumps, you have the same downsizing: the higher your rotor speed, the smaller and lighter a pump can get for the same pressure change and mass flow. Also, for turbo-pumps, a higher rotor speed means the turbine can run faster and be more effective.So, you are pretty soon getting in hells kitchen: If you want less good parts, the parts will get heavier or the performance of your spacecraft has to drop. When the parts get heavier, you need more performance from the other parts to compensate or the spacecraft performance will drop.Now the annoying part starts as well: For a TSTO, you can compensate a performance drop of your second stage by making the first stage better (or the other way around). But there are limits. A SSTO has no such option, it can only try finding a better planet to launch from.Thus, a first stage, that could for example haul a single low-performance second stage into its launch window, could also maybe carry two higher-performance vehicles with the same payload each. Or you could grow an existing first stage for something obsolete and low-performing into something that can launch two modern second stages. or shrink to become more effective itself.", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.617122048Z", "author": "Linguofreak", "date": "2010-05-09T03:06:01+0100", "id": "69df44c9ac5edbfb960bbd3ee69221b7", "post_id": "post-220758", "text": "Urwumpe said:(Also, I think it is far too soon for that question.

The expendable parts of STS weren't the problem here, it was rather how the reusable parts needed to be treated.To have any benefit from reusability, you need to do it correctly. There are many ways you can fail and many ways you could succeed. This is what makes your \"the cut of two orders of magnitude comes from reusability\" claim even more annoying.This is why I ask you time, and time, and time again, for the calculation(s) that you performed that led to the \"two orders of magnitude\" statement. \"It comes from reusability\" is no calculation, it is just an empty claim. The more extraordinary something is, the more extraordinary evidence it needs behind it.The low cost, expendable test version is important because it will show not only that SSTO's are possible\n\nThe expendable test version would be a total waste of time, better to test out subscale models\/construction techniques to verify predictive calculations and estimations of mass.in fact they can be done at high payload fraction.\n\nThis is your claim, and as I understand it, a pretty dubious one.you had so much payload that you could add reentry\/landing systems and still have significant payload left over.\n\nAgain, your claim, and one that I have trouble believing. Have you ever calculated the mass of these systems?Conservatively, and not with \"modern materials magically cut this mass in half\"?I think it's been shown that reusability (in present form of the words) is still somewhat mythological.\n\nIt isn't mythological just because it hasn't been done right before (unless you ask Mike Griffin). The SSME took a high performance, bleeding-edge-of-technology engine and tried to make it reusable. And on top of that, they increased the throttle rating to increase payload.So there's no wonder the engine required such intense refurbishment. It doesn't necessarily have to correlate with other engines, but it can correlate with high performance ones, which is generally why you don't want to stick to those.There are other options: for example, you could run the SSME at a 70% throttle setting throughout the flight. This will reduce T\/W and ISP (a bit), and make the engine grossly overdesigned for this role, but this could help both with reusability and reliability.TheCommon Evolved Cryogenic Engine(CECE, an RL-10 derivative) is listed on the PWR website as having a service life of 10 000 seconds, and 50 in-space starts.This is enough for perhaps 20 flights, including a two-burn trajectory.Inthis threadon the NSF forums, it is said that the RS-68 has a flight rating of 1200 seconds, a maximum burn time certification of 1800 seconds, and has been tested to a maximum of 2400 seconds and 8 starts (unfortunately the link provided as a source no longer seems available). The limiting factor in the RS-68's maximum burn time is most probably the ablative nozzle, and even at a maximum of 1200 seconds, you can fit in four whole 250 second burns.The limiting factor in actually making the RS-68 reusable is probably a lack of access panels, etc.So if you have a $10-30 million engine (and RL-10s are relatively cheap), that you could reuse 20 times or more for only a bit of inspection between each flight, you could achieve pretty significant cost savings. Still not down to two orders of magnitude less- for that, you'd probably have to amortise the cost of the hardware over perhaps something like 1000 flights.I'm not saying that is impossible- maybe an enginecouldexist someday that could be robust enough and with good enough monitoring systems to withstand and that have a low refurbishment cost, but if you look at the RL-10, it is a pretty low performance engine- in terms of ISP it is quite good, but it has a far lower chamber pressure than say the SSME (640 psi on the RL-10-B2, compared to 3280 psi on the SSME), and makes up for it with a high expansion ratio (the RL-10 is a vacuum engine so this doesn't matter, the flip side is that it cannot be used from takeoff and is thus unsuitable for an SSTO unless it has athrust augmented nozzle).RGClark keeps saying that with the highest performance engines around, SSTO can be created and costs can be reduced by two orders of magnitude. But \"highest performance\" and \"cost reduction\" just don't jive. You don't want to have to select for the highest performance around, but rather the most reliable, practical system.The thing is, SSTO only makes economic sense for reusability, and the reason it is attractive for reusability is because it simplifies the recovery and re-launch process. However, if you have to deal with the burden of extra costs from the propulsion side for example, this advantage could quickly diminish and won't be worth it at all.", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.552586752Z", "author": "flytandem", "date": "2011-01-10T21:25:43+0000", "id": "0978bebc80a6393ba4d7fde306e3d9e3", "post_id": "post-252909", "text": "2399! wow.

It wouldn't have to be anything extensive like perhaps what Boeing is planning with their X-37B derivedSSTO.A small one could be demonstrated by amateur science or technical organizations, for instance by the British Interplanetary Society, or the Planetary Society.The Planetary Society is spending about $5.8 million total on their two attempts at solar sail demonstators:Cosmos 1.Cosmos 1 - Wikipedia, the free encyclopediaLightSail-1.http:\/\/en.wikipedia.org\/wiki\/LightSail-1#CreationA small SSTO demonstrator that could carry a few hundred pound payload could be developed for less than this amount and would be far more important for it would show that low cost SSTO's are possible.In fact the organization developing it could even make money on it because they could use it to launch small scientific payloads.\n\nFor the purpose of just making the demonstration it might work to make the vehicle half the size of the one I described here:http:\/\/www.orbiter-forum.com\/showthread.php?p=292116&postcount=136So it would use one RD-0242 engine, have a propellant load about 10,000 kg, and, perhaps, have a dry weight of 475 kg. However, vehicle dry weights don't scale linearly. Scaling a vehicle up actually improves your mass ratio. So by making the vehicle half-scale we probably would not get as good a mass ratio, i.e., the dry mass would likely be more than just half that of the full sized vehicle.In addition to the amateur science organization funded test SSTO's, it might be funded as an X-prize competition. This might have the same effect as the Ansari X-Prize had in spurring commercial suborbital ventures. It would spur manned commercial orbital ventures.However, these would need high performance turbopump fed engines. This is an entire level of difficulty above that of the suborbital rockets which just use pressure-fed engines. In fact the complexity of turbopump fed engines have led rocket engineers to opine \"orbital launchers are turbopump developments with rockets attached\".I recommend teams attempting the venture engage in partnerships with Aerojet or Pratt & Whitney who have experience with high chamber pressure, turbopump-fed engines, especially of the Russian type. They both also have experience in converting an engine from one fuel to another, Aerojet with the conversion of the Titan II engines from kerosene to hypergolics, and Pratt & Whitney more recently with the conversion of the Apollo lunar lander engines from hypergolics to methane.Their costs would be partially defrayed by the amount of the X-prize. This prize amount should at least be that of the $30 million total prize money offered for the Google Lunar X-Prize competition, since its importance greatly exceeds it. Note too for such prize competitions the amount spent by the teams often exceeds that offered by the prize. They could also be offered a portion of the profits that would come from development of the vehicles as small payload orbital launchers.For this prototype test vehicle you probably would not need to use the SpaceX weight optimized Falcon 1 first stage since you just want to get positive payload to orbit. Interestingly I found that Armadillo Aerospace has successfully used common bulkhead design which saves significantly on tank weight for their suborbital test rockets. They would be a good choice for a low cost stage.However, Armadillo has not been successful in their last two suborbital test flights, apparently due to failures in guidance and control. Though Armadillo apparently has solved this for hovering vehicles, it is a significantly more difficult problem for a vehicle traveling at high speed. I recommend a partnership with the MIT Draper labs. They did the G & C for the Apollo missions. More recently they are engaged in partnerships to win the Google Lunar X-Prize.Bob Clark---------- Post added at 07:02 PM ---------- Previous post was at 01:40 AM ----------A common estimate is that orbital flight is an order of magnitude more difficult than suborbital flight, as measured for example by the energy requirements. On that basis a prize for a commercial manned flight to orbit might be 10 times that of the suborbital X-Prize, so to $100 million. This is actually probably doable considering that the required engines and stages already exist to do it as an SSTO.Another source for funding might be Bigelow Aerospace. Bigelow had offered a prize in 2004 of $50 million for a commercial reusable manned launcher to orbit. The prize though expired in January 2010 with no takers:America's Space Prize.http:\/\/en.wikipedia.org\/wiki\/America's_Space_PrizeHowever, the original Orteig Prize for a non-stop cross Atlantic flight also expired with no takers. It was the second offer of the prize for an additional 5 year period which was won by Lindbergh.Then Bigelow could offer the manned space flight prize for an additional 5 year period. But the original conditions for the prize were probably too ambitious. Bigelow appeared to want manned transport craft to his Bigelow space hotels to be fully developed from the winner of the prize in his requiring a 5 man vehicle. However, following the example of the suborbital X-Prize, just accomplishing a small 1 man test flight would be sufficient to serve as an impetus for commercial ventures to invest in developing such launchers aside from the prize.Then I suggest Bigelow lower the requirement to only needing a single crew member. This would allow multiple test flights before a manned flight is attempted.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:35.868063232Z", "author": "Unstung", "date": "2012-08-06T06:26:50+0100", "id": "acf9cf660bc53e0fa2fd2129f0ef1ed2", "post_id": "post-251569", "text": "That was the end of peak heating and acceleration.

However, discussions on other forums have said it would only have 3 engines. That would make sense since on stage return, you are using at most 3 engines, and moreover this way, you would not be risking an expensive loss of 9 copies of the Merlins during these Grasshopper test flights.Still, in point of fact there would be an advantage of using all 9 engines on this first stage Grasshopper, and with a full propellant load. In November, 2012 Elon Musk gave a lecture in London at the Royal Aeronautical Society.Elon Musk lecture at the Royal Aeronautical Society - YouTubeAbout 30 minutes in, he gave the propellant fraction of the new Falcon 9 v1.1 as around 96%, or perhaps 95.5%. The 96% propellant fraction number gives a 25 to 1 mass ratio. But at an Isp of 311 s for the Merlin 1D, the rocket equation gives a delta-v of 311*9.81ln(25) = 9,800 m\/s. Since the delta-v to orbit is only about 9,100 m\/s, this would allow a significant amount of payload.Then using the 9 engines and the full propellant load on the F9 first stage would allow in fact not just a VTVL test vehicle, but in fact a fully reusable and fullyorbitalvehicle.Amusingly, about 36 minutes into Elon's lecture someone asks a question about what he sees as the next big breakthrough in rockets after full reusability. Elon thinks for awhile and can't come up with an answer. He finally jokes maybe warp drive. Ironically, he already has the next big advance: a reusable SSTO.\n\nSpaceX has given the propellant amounts for both the first and second stages in the required Environmental Impact report for the Falcon 9 v1.1. These propellant amounts have been much speculated about on the internet. The amount for the first stage is about what has been estimated. However, the propellant load for the second stage is about 50% higher than the estimates.Given this and the propellant fraction for the first stage given by Elon in the Royal Aeronautical Society lecture, you can calculate the dry mass at least for the first stage. Plugging these values into the rocket equation you see it can carry quite a significant amount of payload as an SSTO.However, an SSTO achieves its best performance when altitude compensation such as aerospike is used. Then the payload in fact becomes surprisingly high. So high in fact that the cost per kilo of the expendable SSTO F9 is better than that of the standard expendable two stage without altitude compensation.In other words by investing in altitude compensation, the F9 first stage SSTO is a more efficient launcher than the standard two stage F9 if you don't invest in altitude compensation. Surprisingly, this superiority of the SSTO on the cost per kilo metric, is still true for the reusable launcher case, even when you make an apples-to-apples comparison of also giving the two stage an altitude compensating first stage.Discussion here:The Coming SSTO's: Falcon 9 v1.1 first stage as SSTO, Page 2.http:\/\/exoscientist.blogspot.com\/2013\/11\/the-coming-sstos-falcon-9-v11-first.htmlBob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:35.974788096Z", "author": "mojoey", "date": "2012-08-07T07:24:58+0100", "id": "38e01b7414351e79812c1b6260feabac", "post_id": "post-251742", "text": "fraxudemspas said:\n\nThis guy looks like this guy...Also this.Aannd now presenting: Condescending Voyager!", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.6221632Z", "author": "gaidheal", "date": "2010-05-10T21:43:20+0100", "id": "88ec306cd5498d93c92b05da5a3f4ba4", "post_id": "post-220800", "text": "HelloPerhaps, after a colony is established on Mars, an exploratory mission to Europa (moon of Jupiter) could be considered.I've been using Orbiter for less than a week, and love it already.

It carries cameras, a robotic arm, drill and even a laser to vaporize bits of rock at a distance.That's too much work for solar panels to power, so NASA is fueling the rover with a plutonium-powered battery of sorts called a multi-mission radioisotope thermal generator, or MMRTG. Loaded with 10 pounds of the material, the power source is expected to generate electricity for a mission lasting at least two Earth years.\"It requires a fancy power supply in order to do the job,\" said Dr. Pam Conrad, deputy principal investigator for MSL. \"This enables us to make measurements all day, every day, at night, in the winter.\"Before researchers get a taste of groundbreaking research about Mars, the launch team at NASA's Kennedy Space Center in Florida is focusing on its responsibility to safely launch the spacecraft and its power source.Even if there were an accident and a release of plutonium, something officials put at a 3-tenths of one percent chance of happening, the material would most likely remain on federal property either at Kennedy or Cape Canaveral Air Force Station, the mission's launch site.However, preparation has been the foremost thought for NASA officials and the launch team will be beefed up with officials from the Lawrence Livermore National Laboratory in Calif., specifically the National Atmospheric Release Advisory Center, or NARAC, a team that models plumes to predict radiation hazards.Ron Baskett, an atmospheric scientist for NARAC, said a network will be in place on launch day to feed critical information to the Livermore lab to generate the models if there is a release of radioactive material.Even the network to collect that data will be strengthened a bit over the usual launch day measures. The National Weather Service's Melbourne office will focus some of its instruments on Cape Canaveral Air Force Station on the day of launch, now targeted for Nov. 25.For its part, NASA and the Air Force's 45th Space Wing have 46 towers to collect wind data and two more detailed instruments that collect information about conditions more than 20 miles above Earth.\"We believe we have the right team put together, with the right people and all the control and functions that you might expect for this type of launch,\" Brisbin said.Officials expect a normal launch day, culminating in an Atlas V lifting Curiosity off the Earth and on a path to Mars.\"If you see a plume, it does not mean there's been an accident,\" said Dr. Frank Merceret, director of research for Kennedy's weather office. Most launches produce a plume of some sort, he said, and even accident would not necessarily indicate any radiation has leaked from the spacecraft.NASA has used the power units 26 times in the past, including the Apollo moon landings and the Viking landers on Mars. Also, they've been used to power the Pioneer and Voyager spacecraft, along with the Galileo mission to Jupiter. More recently, the Cassini mission to Saturn and New Horizons mission to Pluto both run on RTGs. All were launched safely.{...}NewScientist:Mega-rover ready to hunt for life signs on Mars", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.644113664Z", "author": "fireballs619", "date": "2010-06-01T16:17:40+0100", "id": "92e7a1cf0494023543a50a6ec945056f", "post_id": "post-220980", "text": "After reading all 31 pages of posts, I've decided I want in on this.

NASA is in a quandary right now about what to do about their manned flight capability. Congress wants this reinstituted quickly but NASA says they can't do it with the money being provided by Congress.In regards to this proposal it is notable McDonnell Douglas, now a subsidiary of Boeing, was also the contractor on the DC-X, legendary for its low development cost, quick turnaround time, and small ground crew.In this report Boeing proposes heavy lift launchers using existing components:Heavy Lift Launch Vehicles with Existing Propulsion Systems.Benjamin Donahue, Lee Brady, Mike Farkas, Shelley LeRoy, Neal GrahamBoeing Phantom Works,Huntsville, AL 35824Doug BlueBoeing Space Exploration,Huntington Beach, CA 92605http:\/\/www.launchcomplexmodels.com\/Direct\/documents\/AIAA-2010-2370-650.pdfOne of the proposals is of a manned launcher with the Orion capsule using a shuttle ET propellant tank and four RS-68 engines. This does not use an upper stage but is not a single-stage-to-orbit vehicle because the final push to orbit is made by the onboard thrusters on the Orion spacecraft.However, it is interesting in this report comparison is made to theS-IVBupper stage on the Apollo rocket. I was reminded of a suggestion of Gary Hudson that the S-IVB would be single-stage-to-orbit with significant payload if it used the high efficiency SSME rather than the J-2 engine:A Single-Stage-to-Orbit Thought Experiment.Gary C Hudsonhttp:\/\/www.spacefuture.com\/archive\/a_single_stage_to_orbit_thought_experiment.shtmlIn Hudson's proposal the vehicle could lift 10,360 lbs, 4,710 kg. This would be just enough to carry the crewed version of theDragon spacecraftwithout cargo. Boeing's proposal for a manned capsule the CST-100 might be launchable by this also since it is of comparable size and design to the Dragon:Boeing space capsule could be operational by 2015.BY STEPHEN CLARKSPACEFLIGHT NOWPosted: July 21, 2010http:\/\/www.spaceflightnow.com\/news\/n1007\/21boeing\/NASA has shown in their crewed spacecraft versions to want to hearken back to Apollo in their use of capsules. This SSTO idea of Hudson would have the advantage of using a proven Apollo component that is already manrated. The SSME's are also already manrated rather than the RS-68 of the Boeing proposal.Because of its small small size compared to the shuttle ET propellant tank it would also be relatively low cost as well as only needing one SSME engine. In fact it would even be smaller than the Falcon 9, Delta IV, and Atlas V expendable launchers. Note as well NASA is leaning now to using SSME's or their expendable versions rather than the RS-68 for their shuttle derived manned launchers.Hudson in his article stated the S-IVB was designed by the Douglas Aircraft Company, which merged with McDonnell Aircraft to form McDonnell Douglas. McDonnell Douglas is now a division of Boeing, so Boeing should have access to the design documents of the S-IVB.NASA in their shuttle-derived launcher studies have focused on getting a cheaper version of the SSME by making an expendable version. However, the greatest advantage of a SSTO is in being reusable. Then I suggest studies be made on the SSME going the opposite direction: how can it be made to be reusable at much reduced maintenance cost?Now the SSME's have to be overhauled after every flight costing ten's of millions of dollars. However, Henry Spencer a highly regarded expert on the history of space flight has said Rocketdyne studies show that with a lot of work to upgrade it, maintenance could be reduced to $750K per flight:Engine reusability (Henry Spencer)http:\/\/yarchive.net\/space\/rocket\/engine_reusability.htmlSpencer here said this would not be satisfactory for really large reductions in space costs. But this would be a reduction in SSME maintenance costs by 1 to 2 orders of magnitude, a major reduction in the costs for using the engine.

I guess I should not have been surprised by this. The thesis I have been arguing repeatedly via email with individuals in NASA and the industry and on space forums such as this one is that if you use BOTH the most weight optimized designs AND the highest efficiency engines available, then what you will wind up with will be SSTO capable whether you intend it to or not....We'll take the liftoff thrust\/weight ratio to be 1.2. This will bring the gross mass down to 170,000 kg. Then the propellant mass has to be reduced by 34,000 kg. This brings the propellant mass down to 156,850 kg. Note this results in a mass ratio close to 13, well sufficient for SSTO with a hydrogen-fueled engine....Then using Hudson's 425s average Isp for the SSME and the 9,200 m\/s required delta-V value for orbit, this stage as an SSTO could loft 6,200 kg to orbit:425*9.8ln(1 + 156,850\/(13,150 + 6,200)) = 9,200 m\/s.Again, we might be able to loft 10% greater total mass to orbit withpropellant densificationby subcooling and also shave 10% off the structural mass of the stage with therecent weight saving research. This will bring the payload mass up to about 9,000 kg...\n\nThere might still be some resistance to using the upper stage as a SSTO. However, the point of the matter is even if you use these upper stages as part of a multistage system you are still better off usingbothhighly weight optimized structuresandengines of highest surface-to-orbit-efficiency (not just vacuum optimized engines)at the same time.We'll use in this case parallel staging of the same sized stages, abimeseversion, but using cross-feed fueling. This is a fueling method that has both stages firing, as with parallel staging, but all the propellant is coming from only a single stage at a time. Then when that stage exhausts its propellant, it is jettisoned, and the remaining stage proceeds on with its own full tank of propellant still remaining.Let's see how much payload we can carry in this case. Again assume the 425s trajectory averaged Isp of Hudson, and the 9,200 m\/s required delta-V for orbit.Estimate the possible payload as 29,000 kg. For the first segment of the flight the achieved delta-V would be: 425*9.8ln(1+156,850\/(2*13,150 + 156,850 +29,000)) = 2,305 m\/s.For the second segment, use the 455s vacuum Isp of the SSME's:455*9.8ln(1 + 156,850\/(13,150 + 29,000)) =6,921. And the total delta-V is 9,226 m\/s, sufficient for orbit with a 29,000 kg payload.Note that a 29,000 kg payload is sufficient to even carry a Orion capsule, at least in an expendable version of the staged vehicle without reentry and landing systems.Then you have different options for the vehicle. As a single stage it could carry a small capsule such as the SpaceX Dragon, or the Boeing CST-100. But using twinned copies of it, it would be able to loft the heavier Orion spacecraft.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.632763392Z", "author": "Bj", "date": "2010-05-19T01:48:40+0100", "id": "93e089b0490bcf03bea945c7fdfc0338", "post_id": "post-220900", "text": "Columbia42 said:I'll start doing some preliminary models of the surface base including (hopefully) the CM.

First, the good news: the landing ellipse has shrunk. What does that mean? When you try to land something on Mars, you aim at a specific location, but nature has a way of throwing unexpected things at you. The Curiosity team has built extremely sophisticated computer models of their spacecraft and of the Martian atmosphere and then threw a jillion different sets of starting conditions at the simulated rover on landing day. Those simulations result in a scatter plot of sorts of likely actual landing sites for the rover. Draw an oval around those, and you have what's called a landing ellipse. {...}Anyway, getting back to Curiosity, the landing ellipse used to be 25 kilometers long by 20 kilometers wide, but now it's much smaller: 20 by 7. This is actually not a surprise -- throughout the site selection process it was mentioned that the final ellipse would likely shrink -- but I am pleasantly surprised by how small they got it.{...}The bad news: there's a lurking problem with the drilling system, in that there are materials including Teflon and molybdenum disulfide (if I understood John Grotzinger correctly) that wind up getting mixed with the sampled rock and delivered to the science instruments.

Strickland, Jr.September, 2011\"What amazes people is that SpaceX has broken the long-sought 1,000dollars a pound to orbit price barrier with a rocket which is stillexpendable. 'How can he (SpaceX CEO Elon Musk) possibly do this?' theyask. The Chinese have said flatly that there is no way they cancompete with such a low price. It is important to remember that thiswas not done in a single step. The Falcon 9 already has a large priceadvantage over other boosters, even though it does not have thepayload capacity of some of the largest ones. The 'Heavy' will eventhis score and then some. At last count, SpaceX had a launch manifestof over 40 payloads, far exceeding any current government contracts,with more being added every month. These are divided between theFalcon 9 and the Falcon Heavy.\"http:\/\/www.nss.org\/articles\/falconheavy.htmlI think the most important accomplishment of SpaceX might turn outto be that they showed in stark terms that privately financed spacecraft,both launchers and crew capsules, can be accomplished at 1\/10th thedevelopmental cost of government financed ones. Imagine a manned,reusable orbital launcher, for example, instead of costing, say, $3 billion,only costing $300 million to develop.As I argue, the key variable that made this reduction possible is thatthe launcher was privately financed. That is, it was the launchcompany's own money that was financing its development. In that caseit makes sense the company would be more fiscally responsible indeveloping it.Then the first step in reducing the price to orbit is making thevehicles be privately financed. But if the launch companies are goingto spend their own money, they have to be convinced they can make aprofit on them. This will come if there is a significant market.My view is that there would be a significant market for small,privately owned, SSTO's. When you consider that with orbital refuelingsuch craft can also make lunar missions, the market becomes even moreapparent.An additional finance stream of such vehicles that would make themmarketable I argue could be salvage of satellites in LEO or GEO:Space junk at 'tipping point', now getting worse on its own.More collisions generate more debris, so more collisions.By Gavin ClarkePosted in Space, 2nd September 2011 11:18 GMThttp:\/\/www.theregister.co.uk\/2011\/09\/02\/space_junk_danger\/Article:World's First Space Gas Station for Satellites to Launch in 2015.by Clara Moskowitz, SPACE.com Senior WriterDate: 15 March 2011 Time: 06:03 PM ET\"Until now, satellites orbiting around Earth have been limited by howmuch fuel they carry onboard.

Some pyrotechnics will be as small as the energy released by a box of matches. One packs the same oomph as a stick of TNT. Whether they be large or small, on the evening of August 5th (Pacific time), all 76 must work on cue as NASA's next Mars rover, Curiosity, carried by the Mars Science Laboratory, streaks through the Red Planet's atmosphere on its way to a landing at Gale Crater.Click on image to enlarge\u200bOne month and a day after America celebrates its independence with fireworks, a series of meticulously-engineered fireworks must operate for the Curiosity rover to safely reach the surface of the Red Planet as shown in this artist's concept.Image credit: NASA\/JPL-Caltech\u200b\"We are definitely coming in with a bang - or a series of them,\" said Pete Theisinger, Mars Science Laboratory project manager at NASA's Jet Propulsion Laboratory in Pasadena, Calif. \"You only get one shot at a Mars landing, and the pyrotechnic charges we are using are great for reliably providing instantaneous, irreversible actions like deploying a parachute or opening a fuel valve.\"Explosive pyrotechnic devices predate the space age by about a thousand years. Around 750 A.D., people in China began stuffing an early form of gunpowder into bamboo shoots and throwing them into a fire. At some point, someone interested in taking this new discovery to the next level (probably also from that region), decided aerial explosions would be even cooler, and the \"aerial salute\" was born. Fireworks were also part of America's very first Independence Day in 1777.Pyrotechnics, or pyromechanical devices, are a natural but highly-engineered extension of these early fireworks. Instead of a rocket's red glare and bombs bursting in air, the energy from these explosions is contained within a mechanism, where it is used to move, cut, pull or separate something. Controlled explosions are a valuable tool to those who explore beyond Earth's atmosphere because they are quick and reliable.\"When we need valves to open, or things to move or come apart, we want to be confident they will do so within milliseconds of the time we plan for them to do so,\" said Rich Webster, a pyromechanical engineer at JPL. \"With pyros, no electrical motors need to move. No latches need to be unlatched. We blow things apart -- scientifically.\"Seventeen minutes before landing, the first 10 of 76 pyros will fire within five milliseconds of each other, releasing the cruise stage that provided the entry capsule (and its cocooned descent vehicle and the Curiosity rover) with power, communications and thermal control support during its 254-day journey to Mars.\"We have essentially three miniature guillotines onboard that, when the pyros fire, cut cabling and metal tubing that run between the cruise stage and the entry capsule,\" said Luke Dubord, avionics engineer for Mars Science Laboratory at JPL. \"Then a retraction pyro pulls them out of the way. Along with that, we've got six pyrotechnic separation nuts, which when fired, will actually accomplish the separation.\"One hundred and twenty-five milliseconds later, two more pyros fire, releasing compressed springs that jettison two 165-pounds(75-kilogram) solid tungsten weights. These weights allow the entry capsule to perform history's first planetary lifting body entry (seehttp:\/\/mars.jpl.nasa.gov\/msl\/mission\/technology\/insituexploration\/edl\/guidedentry\/). A dozen minutes and one fiery, lifting-body atmospheric reentry later, another smaller set of tungsten weights is ejected by pyros to re-adjust the lander's center of mass for the final approach to the surface. A few seconds after that, the largest bang since the spacecraft separated from its Atlas rocket 254 days before is scheduled to occur.\"The Mars Science Lab parachute is the largest used on a planetary mission,\" said Dubord. \"When folded up and in its canister, it's still as big as a trashcan. We have to get that folded-up chute out of its canister and unfolding in a hurry. The best way to do that is get it quickly away from spacecraft and out into the freestream using a mortar.\"The best way to do that, the engineers at JPL decided, was to include a pyrotechnic charge equivalent to a stick of TNT.\"When something like this goes off, it makes a lot of noise\" said Dubord. \"Of course, at 8.7 miles [14 kilometers] up and a little over Mach 1, over Mars, I doubt anybody will be there to hear it.\"While the ejection of the parachute is the biggest pyrotechnic display during the crucial entry, descent and landing, it is certainly not the last. The landing system needs to be released from the backshell that helped protect it during entry. The sky crane's descent engines need to be pressurized, and the rover itself needs to be released from the sky crane, where it is lowered on tethers toward the surface. All told, there are another 44 controlled explosions that need to happen at exactly the right time and at absolutely no other time for Curiosity to touch down safely at Gale Crater.\"Excluding the parachute mortar, the total 'explosive' material in all the pyrotechnics aboard the spacecraft is only about 50 to 60 grams,\" said Webster. \"That is about the same amount of combustible material in the air bag in your car's steering wheel. When you do the math, the amount of explosive material in each pyrotechnic is only about what you would get out of a pack of matches.\"The thing is, a pack of matches won't help you land on Mars....pyrotechnics will,\" Webster added.The Mars Science Laboratory mission is managed by JPL for NASA's Science Mission Directorate in Washington.

The Merlin 1D has a 147,000 lb sea level thrust:Modified Merlin engine completes full duration firing.BY STEPHEN CLARKSPACEFLIGHT NOWPosted: June 25, 2012http:\/\/www.spaceflightnow.com\/news\/n1206\/25merlin1d\/The gross mass of the Falcon 9 first stage with the Merlin 1D's and a 1.2 mT payload would be 250 + 11.8 + 1.2 = 263 mT, 578,600 lbs. This could be lofted by just 4 of the Merlin 1D's. But the thrust would be just a little over the gross mass resulting in high gravity loss. So let's use 5 Merlins. Subtracting off 4 Merlins makes the dry mass 11,800 - 4*450 = 10,000 kg.The number of 30,000 fps delta-v for LEO is assuming a T\/W ratio common for liquid fueled rockets, in the range 1.1 to 1.2. With all 9 Merlins the T\/W ratio would above 2.2. This would result in a much reduced gravity loss. So the required delta-v would be less than the 30,000 fps number, and so actually higher than 1.2 mT could be sent to LEO even in that case.But let's look at the case of using 5 Merlins. SpaceX has given a vacuum Isp of the Merlin 1D as actually 311 s. Then we could send 3.1 mT to LEO:311*9.81ln(1 + 250\/(10 + 3.1)) = 9,152 m\/s.SpaceX has said though they want to move to a larger version of the Falcon 9 called the Falcon 9 v1.1, in accordance with the Merlin 1D's larger thrust. The Falcon Heavy will use this version's first stage for its core stage and side boosters. SpaceX expects the Falcon 9 v1.1 to be ready by the end of the year.Elon Musk has said the version 1.1 will be about 50% longer:Q&A with SpaceX founder and chief designer Elon Musk.BY STEPHEN CLARKSPACEFLIGHT NOWPosted: May 18, 2012http:\/\/www.spaceflightnow.com\/falcon9\/003\/120518musk\/I'll assume this is coming from 50% larger tanks. This puts the propellant load now at 375,000 kg. Interestingly SpaceX says the side boosters on the Falcon Heavy will have a 30 to 1 mass ratio. This improvement is probably coming from the fact it is using the lighter Merlin 1D engines, and because scaling up a rocket actually improves your mass ratio, and also not having to support the weight of an upper stage and heavy payload means it can be made lighter.So I'll assume for this SSTO version of the Falcon 9 v1.1 the mass ratio is 30 to 1, which makes the dry mass 13 mT. Then this version can lift 6.7 mT to LEO:311*9.81ln(1 + 375\/(13 + 6.7))Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.49628672Z", "author": "Suzy", "date": "2010-09-02T07:17:56+0100", "id": "3fc3a1ff28cc62e811ccc243a48d3b1c", "post_id": "post-252695", "text": "And some women wonder why they aren't taken seriously...what a bimbo!:rolleyes:(She also looks like she's had some \"chest enhancement\")", "thread_id": 16320 }, { "@timestamp": "2023-09-14T07:13:05.296233472Z", "author": "dbeachy1", "date": "2010-04-27T23:07:01+0100", "id": "bb55cdc876d2011b3911e1d8745d3e0a", "post_id": "post-219760", "text": "Have you verified that your video mode is set to \"Direct3D T&L HAL\"?

It's based on the idea that inflating a structure can increase its compressional and bending strength. Consider an inflated tire or basketball for example. Then this fact was used to reduce the thickness of the walls of the Atlas tanks. The reduced strength of the walls was made up for by the increased strength due to the internal pressure.In fact for the Atlas its walls are so thin the structure can not stand on its own when empty. When in storage its propellant tanks are filled with nitrogen. Otherwise it would collapse under its own weight:Atlas.http:\/\/www.astronautix.com\/lvs\/atlas.htmAs for a weight breakdown for the propellant tanks of a proposed SSTO, see the the estimates at the end here:Mass Estimating Relations\u2022 Review of iterative design approach\u2022 Mass Estimating Relations (MERs)\u2022 Sample vehicle design analysishttp:\/\/spacecraft.ssl.umd.edu\/academics\/483F09\/483F09L13.mass_est\/483F09L13.MER.pdfNote the propellant tanks for this hydrogen fueled SSTO weigh more than the engines. This problem of tank weight is especially true for hydrogen fueled vehicles because the tanks for hydrogen have to be so large, therefore heavy, because of hydrogen's low density.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.403212288Z", "author": "Urwumpe", "date": "2010-04-28T12:06:22+0100", "id": "17b75af7471acb66e06287b357f2cb9c", "post_id": "post-219797", "text": "Would be easier of you say which scenario you downloaded and what add-on it is part of.", "thread_id": 14045 }, { "@timestamp": "2023-09-14T07:13:05.553340416Z", "author": "RGClark", "date": "2011-12-08T10:00:13+0000", "id": "43b805e3fb1ee8a774146a3c76a4d0c5", "post_id": "post-220285", "text": "RGClark said:Space Travel: The Path to Human Immortality?Space exploration might just be the key to human beings surviving mass genocide, ecocide or omnicide.July 24, 2009On December 31st, 1999, National Public Radio interviewed the futurist and science fiction genius Arthur C. Clarke. Since the author had forecast so many of the 20th Century's most fundamental developments, the NPR correspondent asked Clarke if anything had happened in the preceding 100 years that he never could have anticipated. \"Yes, absolutely,\" Clarke replied, without a moment's hesitation. \"The one thing I never would have expected is that, after centuries of wonder and imagination and aspiration, we would have gone to the moon ... and then stopped.\"http:\/\/www.alternet.org\/news\/141518\/space_travel:_the_path_to_human_immortality\/I remember thinking when I first saw 2001 as a teenager and could appreciate it more, I thought it was way too optimistic. We could never have huge rotating space stations and passenger flights to orbit and Moon bases and nuclear-powered interplanetary ships by then.That's what I thought and probably most people familiar with the space program thought that. And I think I recall Clarke saying once that the year 2001 was selected as more a rhetorical, artistic flourish rather than being a prediction, 2001 being the year of the turn of the millennium (no, it was NOT in the year 2000.)However, I've now come to the conclusion those could indeed have been possible by 2001. I don't mean the alien monolith or the intelligent computer, but the spaceflights shown in the film.It all comes down to SSTO's. As I argued above these could have led and WILL lead to the price to orbit coming down to the $100 per kilo range. The required lightweight stages existed since the 60's and 70's for kerosene with the Atlas and Delta stages, and for hydrogen with the Saturn V upper stages. And the high efficiency engines from sea level to vacuum have existed since the 70's with the NK-33 for kerosene, and with the SSME for hydrogen.The kerosene SSTO's could be smaller and cheaper and would make possible small orbital craft in the price range of business jets, at a few tens of millions of dollars. These would be able to carry a few number of passengers\/crew, say of the size of the Dragon capsule. But in analogy with history of aircraft these would soon be followed by large passenger craft.However, the NK-33 was of Russian design, while the required lightweight stages were of American design. But the 70's was the time of detente, with the Apollo-Soyuz mission. With both sides realizing that collaboration would lead to routine passenger spaceflight, it is conceivable that they could have come together to make possible commercial spaceflight.There is also the fact that for the hydrogen fueled SSTO's, the Americans had both the required lightweight stages and high efficiency engines, though these SSTO's would have been larger and more expensive. So it would have been advantageous for the Russians to share their engine if the American's shared their lightweight stages.For the space station, many have soured on the idea because of the ISS with the huge cost overruns. But Bigelow is planning on \"space hotels\" derived from NASA'sTranshabconcept. These provide large living space at lightweight. At $100 per kilo launch costs we could form large space stations from the Transhabs linked together in modular fashion, financed purely from the tourism interests. Remember the low price to orbit allows many average citizens to pay for the cost to LEO.The Transhab was developed in the late 90's so it might be questionable that the space station could be built from them by 2001. But remember in the film the space station was in the process of being built. Also, with large numbers of passengers traveling to space it seems likely that inflatable modules would have been thought of earlier to house the large number of tourists who might want a longer stay.For the extensive Moon base, judging from the Apollo missions it might be thought any flight to the Moon would be hugely expensive. However, Robert Heinlein once said: once you get to LEO you're half way to anywhere in the Solar System. This is due to the delta-V requirements for getting out of the Earth's gravitational compared to reaching escape velocity.It is important to note then SSTO's have the capability once refueled in orbit to travel to the Moon, land, and return to Earth on that one fuel load. Because of this there would be a large market for passenger service to the Moon as well. So there would be a commercial justification forBigelow's Transhab motels to also be transported to the Moon.Initially the propellant for the fuel depots would have to be lofted from Earth. But we recently found there was water in thepermanently shadowed craters on the Moon. Use of this for propellant would reduce the cost to make the flights from LEO to the Moon since the delta-V needed to bring the propellant to LEO from the lunar surface is so much less than that needed to bring it from the Earth's surface to LEO.This lunar derived propellant could also be placed in depots in lunar orbit and at the Lagrange points. This would make easier flights to the asteroids and the planets. The flights to the asteroids would be especially important for commercial purposes because it is estimated even a small sized asteroid could havetrillions of dollars worth of valuable minerals. The availability of such resources would make it financially profitable to develop large bases on the Moon for the sake of the propellant.Another possible resource was recentlydiscovered on the Moon: uranium. Though further analysis showed the surface abundance to be much less than in Earth mines, it may be that there are localized concentrations just as there are on Earth. Indeed this appears to be the case withsome heavy metals such as silver and possibly goldthat appear to be concentrated in some polar craters on the Moon.So even if the uranium is not as abundant as in Earth mines, it may be sufficient to be used for nuclear-powered spacecraft. Then we wouldn't have the problem of large amounts of nuclear material being lofted on rockets on Earth. The physics and engineering ofnuclear powered rockets have been understood since the 60's. The main impediment has been the opposition to launching large amounts of radioactive material from Earth into orbit above Earth. Then we very well could have had nuclear-powered spacecraft launching from the Moon for interplanetary missions, especially when you consider the financial incentive provided by minerals in the asteroids of the asteroid belt.Bob Clark\n\nJust saw this article onThe Space Reviewdiscussing a recently discovered copy of a 1963 TV interview with Arthur C. Clarke:The perils of spaceflight prediction.by Jeff FoustMonday, December 5, 2011http:\/\/thespacereview.com\/article\/1981\/1In the interview Clarke gives some predictions of the future of space exploration. From the standpoint of the beginnings of human spaceflight, he suggests a manned Mars mission within 25 years, which would have been by 1988, and Moon bases by the end of the 20th century.This turned out to be too optimistic. But as I argued above, this could indeed have been technically and even financially feasible: if it had been recognized that reusable SSTO's are possible and in fact aren't even really hard, we would have had routine, private spaceflight by the 1970s.Such wide spread, frequent launches using reusable spacecraft would have cut the costs to space by two orders of magnitude, at least. This would then have made the costs of lunar bases and manned Mars missions well within the affordability range.The important point is that the required high efficiency engines and lightweight stages for SSTO's already exist and have for decades. All that is required is to marry the two together. An expendable test SSTO could be produced, like, tomorrow. Just this one simple, cheap test would finally make clear the fact that routine spaceflight is already doable.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.445366272Z", "author": "DanM", "date": "2010-09-01T02:03:18+0100", "id": "805daca472d00fc8aa6b1bddd8985880", "post_id": "post-252574", "text": "I'm attempting a more proper rendezvous (DG-IV to Arrow Freighter).

This way, less mass needs to be hauled around unused. Landing should be first by an inflatable heat shield (along the design of the IRDT, instead of the ballute), then by a skycrane module (just landing engines + enough fuel for flying back to Mars orbit again), that can be reused.The landing areas don't need a special texture, they are just for telling on the map, where to put landing beacons and where to land.A nuclear reactor does not need to be large, there had been one in the Mars Direct project, which had about the same power output as the ISS solar arrays. didn't need large cooling towers, because of the small power output.\n\nOh I see what your saying, the Hab module will stay in its current configuration throughout the entire mission, so it willnot be deploy-able, merely shift positions a lot.So this IRDT, I guess it will be super sized for the hab modules and whatever.

This is a fallacy. Only because most rockets with high propellant density also have a short burn time (solids!), this can backfire for SSTOs. Assuming 8900 m\/s as first-order estimate for designing an SSTO is exactly the wrong direction. First of all, because the value is way off reality, it is calculated by assuming an SLBM ascent profile (no acceleration restraints, extremely high thrust), which needs only little over two minutes for reaching MECO - yes, there you have really low gravity losses.If you also want to reduce acceleration loads on the payload and limit to 3G, you will quickly approach 300 seconds burn time as practical minimum. There is no engineering law cast in silicon carbide, that says that cryogen rocket engines can't provide 3G acceleration for most of the flight.Also, you need to include aerodynamic loads on the rocket - you CAN use brute force for getting through a high max-Q, but this increases your structural mass, resulting in mass that you will have to carry with you until landing. So, unless you can afford the higher structural mass, you will want to have net acceleration down to 1.2 g or even less during the Max-Q phase, and less than 2g on lift-off, because you otherwise have max-Q at too low altitude and too high air density.There is a reason why we still have no SSTO - TANSTAAFL. On the paper, it is simple, if you can choose your first-order estimates to make things work out. But once you get into further iterations of the design, you will be forced to correct your optimistic first-order estimates, making your SSTO quickly unrealistic. And that way is standard for all SSTOs, likely because the first order estimate makes you select a design, that is optimal for your optimistic estimates, but not surviving in reality.", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.618507008Z", "author": "Bloodworth", "date": "2010-05-09T23:09:57+0100", "id": "23d4cbd29a9d50786f5383d400ed2dc1", "post_id": "post-220772", "text": "For goals while on mars, one thing I think we should do is to locate and ascertain the conditions of the Viking landers as well as Spirit and Opportunity rovers (as well as any other spacecraft currently on mars).

The hab\/Command module contains no abort option of its own, instead it is meant to land close to a ERV. During reentry it should be protected by a inflatable heatshield, that is large enough to also protect the skycrane during reentry.If no abort of the mission is needed, the next crew lands on Mars with the next rigid module. This way, the core modules of the mars base are rigid, and the inflatable modules can be used for storage or green houses.The connection to the earth-Mars spacecraft is at the top of the Hab\/Command module and design as such, that during transfer, the spacecraft could spin in yaw direction for providing artificial gravity. When the spacecraft reaches Mars, the hab command modules is detached and the skycrane maneuvers itself for docking with the HC automatically. The rest of the spacecraft remains in (medium) Mars orbit, acting as communication relay and is used again for return from Mars, but this time docking the ERV at its end.Since the Skycrane is separate, the Earth-Mars ship could also contain cargo modules at it, that are delivered to the ground. For the first mission, the Skycrane would get refueled in Orbit, with fuel transported to Mars, so the payload would be reduced, but later missions could refuel on the surface of Mars, if in-situ fuel production is possible.This concept doesn't contain any special assumptions on the technology, it should work with reduced performance with realistic technology as well as being still an economic option with \"DG-Tech\" fictional technology.", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:35.982260992Z", "author": "fsci123", "date": "2012-08-09T15:03:49+0100", "id": "33cbbddad9536dc10a5b3048592d94b9", "post_id": "post-251793", "text": "Just out of curiosity...Do these hi res cameras take video?:shrug:", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:04.90275328Z", "author": "Richy", "date": "2010-04-29T15:12:20+0100", "id": "632b5bf1a8e21c6c0b2122d12ec7164b", "post_id": "post-219477", "text": "That's right, additionally, both engines have to point some degrees outwards, so the exhaust jet doesn't hit the cargo linked behind.edit: too late... ^^May the pulling cable is designed relatively long, so the angle of the engine exhaust gives a remarkable distance between cargo and jet.

It's not a linear progress towards divinity.\n\nHumans are not entirely brutal. Humans are actually a good example of what happens to animals which become intelligent and self-aware. Our social progresses have caused a lot of primitive instincts to almost disappear. We can take decisions rationally and consciously rather than just driven by a feeling of hunger and what genes tell us to do. We decide to have sex consciously because we want to enjoy it, not just to beget children and do self-preservation, but even consciously try to be without children (which is in some regions a problem).Scientific (and its technological) progress actually goes not along with brutality. Brutality is what is caused politically. We don't go into space to be brutal. We go into space because we are curious and because we want to explore places we have never seen before. I expect the same for other intelligent species because we live in the same universe and certainly consist of the same elements under almost equal laws. And if those species are able to travel light years of distances, I think it is for sure that they have reached a state of intelligence and rationalism that is ahead of ours.But the fact that it took quite a while until there was the proper conditions for intelligent life on our earth, and this compared with the age of the universe, drastically shrinks the chances that there are other comparable forms of life anyway I think.

Evaluating ceramic matrix composites for radiation coolednozzles.The goal is to develop and demonstrate these new technologiesso that they may be incorporated into future rocketengines.Using lightweight ceramics has the potential to reducethe weight of the combustion devices by up to 50%....Table 1 lists the materials and type of construction ofnumerous combustion devices, both historical and current. Asthe table shows, the materials of choice (for all the engine manufacturers)for combustion devices in large liquid fueled rocketengines have historically been stainless steels, nickel-basedsuperalloys, and copper alloys. These materials are selected fortheir high strength and high thermal conductivity in orderto cope with the stresses and extreme thermal environmentsof rocket engines. Since these alloys also have high densities(8-9 g\/cm3), widespread reliance on them has traditionallyresulted in heavy engines.Designers would like to reduce the weight of rocketengines. A key performance criterion for engines is thrust-to-weightratio. Lighter engines and launch vehicles would allowheavier payloads to be placed into orbit at a lower cost. Onepath to lighter weight engines is replacement of conventionalhigh-density engine alloys with lightweight, high specificstrength ceramic composites. Two attractive candidates forthis application are carbon fiber reinforced silicon carbide(C\/SiC) and silicon carbide fiber reinforced silicon carbide(SiC\/SiC). These materials have low densities (2.0-2.4 g\/cm3)and high strengths that they maintain to relatively high temperatures(2400-3000\u00b0F).\n\nhttp:\/\/ammtiac.alionscience.com\/pdf\/AMPQ8_1ART06.pdfReportedly such lightweight, high temperature ceramics have already been used on hypersonic, scramjet test vehicles. Keep in mind also that for this application while you are adding on the weight of the aerospike you are also removing much of the weight of the nozzles.For the size of the engines fitting within the Falcon 9 diameter around a central spike, remember most of the nozzles will be removed. As it is now, 8 engines are in a square pattern with the ninth engine in the center. So there are 4 corner engines with 1 engine between any pair of these corner engines. Then these engines between the corner engines can be moved outside instead to the circumscribed circle around the square. Taking into account the extra space without much of the nozzle width the ninth engines should fit in this space as well.Furthermore, I realized that you don't need all 9 engines now. With the upper stage removed and with the smaller payload, and with the higher thrust and lighter weight of the Merlin 1D, you would need only 5 to 6 of the engines for liftoff. This makes the dry mass even lighter, which can go to further payload.The engines combustion chamber and turbopumps will not have to be changed, only the nozzle. From images of the Merlin 1C it looks like the nozzle is bolted on. So you would bolt on a shorter nozzle, like you bolt on a longer addition when you producing the Merlin Vacuum.2.)Weight of added reentry\/landing systems.a.)Thermal protection.Robert Zubrin has given an estimate of 15% of the landed weight for the weight of thermal protection systems(TPS):Reusable launch system.http:\/\/en.wikipedia.org\/wiki\/Reusable_launch_system#Reentry_heat_shieldsHowever, I gather this was in relation to the older capsules, Mercury, Gemini, Apollo, etc. Indeed the weight of the ablative heat shield on the Apollo capsule was about 15%:Apollo Command\/Service Module.2.7 Specificationshttp:\/\/en.wikipedia.org\/wiki\/Apollo_Command\/Service_Module#SpecificationsHowever, the space shuttle with its mostly silica tiles was able to reduce the TPS weight to about 8% of the maximum landing weight of 104,000 kg:Space Shuttle thermal protection system.3.3 Weight considerations.http:\/\/en.wikipedia.org\/wiki\/Space_shuttle_thermal_protection_system#Weight_considerationsAlso, for the X-37b the TUFROC leading edge material instead of the shuttles RCC and the TUFI AETB material instead of the shuttles silica tiles are either of equal or lower weight than the shuttles TPS materials while being tougher and requiring less maintenance:X-37B Orbital Test Vehicle.http:\/\/www.boeing.com\/defense-space\/ic\/sis\/x37b_otv\/x37b_otv.htmlFor ablative TPS, the PICA-X material used on the Dragon capsule weights about half the weight of the AVCOAT material used on the Apollo heat shield:Re: Dragon v\/s Orion.http:\/\/forum.nasaspaceflight.com\/index.php?topic=23522.msg754168#msg754168while being able to survive lunar and even Martian reentry speeds.SpaceX has found that at least for LEO reentry speed judging from the minimal degradation on the Falcon 9\/Dragon test flight, the PICA-X heat shield could be reused hundreds of times.Also, for vertical powered landings a la the DC-X, you might not even need an extra heat shield for base first landings. One proposal for a VTVL SSTO uses low thrust during the descent as well as the high temperature-resistant aerospike to serve as the reentry thermal protection. You would need to retain more mass in propellant or some inert gas for this purpose though.b.)Weight of the wings and the landing gear.A common estimate is that the weight of wings is 10% of the landed weight. This comes from aircraft examples though where the wings have to carry the weight of the fuel which can be as much as the dry weight of the aircraft itself or more.An example where the propellant will not be carried in the wings and lightweight composites will be used is the Skylon. According to their released specifications the wing weight will be less than 2% of the take-off weight, which is the appropriate weight to compare to for a horizontal take-off vehicle:The SKYLON Spaceplane.by Richard Varvill and Alan BondJournal of the British Interplanetary Society, Vol. 57. pp. 22\u201332, 2004p. 32.http:\/\/www.reactionengines.co.uk\/downloads\/JBIS_v57_22-32.pdfOn that same page the landing gear weight is the only 1.5% of the take-off weight.For a vertical take-off vehicle these low weight proportions should apply to the dry weight.3.)Increasing Isp with altitude compensation.The most important characteristic for having a high vacuum Isp for an engine is having a long nozzle, i.e., area ratio, much more so than the chamber pressure. For instance the RL-10B2 while having a combustion chamber pressure of only 40 bar, has a vacuum Isp ca. 465 s. This comes from its very long vacuum optimized nozzle. And the Merlin Vacuum increases its vacuum Isp to 342 s from the 304 s of the Merlin 1C just by having a long nozzle extension attached.The problem with this for a SSTO is that long nozzles give poor performance at sea level. In fact it's even worse then this. A vacuum optimized nozzle used at sea level can cause instabilities in the exhaust that can damage or destroy the engine. So the purpose of the altitude compensating nozzle is they can give this high performance of vacuum optimized nozzles, yet still work efficiently as well at sea level.4.)Saving weight and increasing payload with a next-gen shuttle.My comment about the shuttle orbiter being too heavy for high payload delivery was only in regards to the fact that every extra pound you take to LEO has to be subtracted from your payload capacity. The shuttle orbiter at ca. 80,000 kg subtracts majorly from the payload capacity of such a large launcher. With the lightweight composites now available we can cut significantly into that orbiter dry mass and therefore increase our payload.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.07024512Z", "author": "MJR", "date": "2010-08-29T02:11:13+0100", "id": "00f9d38aea0279c26036d36b5f277d1e", "post_id": "post-252219", "text": "Since we managed to have picture threads about astronomy, 'COOL' photography, and Orbiter screenies, why not have a random one?

Now the team behind that successful mission proposes a sequel that could pave the way for astronauts to explore an asteroid for the first time.Engineers and scientists from the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., have teamed up with NASA's Goddard and Johnson Space Flight centers to devise \"Next Gen NEAR,\" a concept of a robotic precursor for a human visit to a near-Earth asteroid.In April, President Barack Obama announced a new direction for the nation's space program, including plans for NASA to send the first human mission to an asteroid by 2025. This requires building a capability to live and work in deep space, beyond the Earth-Moon system. Beyond our Moon, asteroids near Earth (called near-Earth objects, or \"NEOs\") are our closest and most accessible planetary neighbors, making them a practical stepping-stone for expanded human space exploration.Only two missions \u2013 NEAR, and Japan's Hayabusa \u2013 have ever visited and touched the surface of a NEO, and scientists say we need more insight into these objects before we can safely send humans.\"We've learned a lot about NEOs using telescopes, Earth-based radar and two robotic missions, but we'd have to get up close and personal with a specific asteroid again, and learn much more about its environment, before we could send human explorers,\" says Dr. James Garvin, chief scientist at Goddard Space Flight Center, Greenbelt, Md. \"But there is nothing intuitive about operating at an asteroid; in fact, sending humans to an asteroid would be one of the most challenging space missions ever. So to make sure we really understand that challenge, we've paired NASA experts in small-body robotic and human spaceflight with the only team in the U.S. to design, build and operate an asteroid-orbiter mission.\"Planners say the mission could launch as soon as 2014 and begin to return data from a target asteroid the following year. The mission's goal is to collect data on the asteroid\u2019s surface and interior, and to scope out potential resources as well as hazards to human visitors. \"We can't make these measurements by telescopic remote sensing from Earth or even by spacecraft flyby encounters or distant rendezvous,\" says Dr. Andrew Cheng, chief scientist in APL's Space Department, who also served as NEAR's lead scientist and is on the Hayabusa team.Experts say landing on a small body, without an atmosphere or gravity, is completely different than landing on a planet like Mars. \"We've worked together to design the Next Gen NEAR concept of operations to parallel, to the extent possible, operations of a future human mission,\" says Rob Landis, a NASA mission operations specialist.\"A mission like this requires extensive science operations from close-in orbit, including contact with the surface.\" says Dr. Paul Abell, of Johnson Space Center, Houston, and also a member of the NEAR and Hayabusa science teams.The Next Gen NEAR spacecraft would run on commercially available subsystems and carry lightweight scientific instruments (such as a camera, composition-measuring spectrometers and even a surface-interaction experiment) with flight heritage. It would be fitted with solar power, propulsion and communications systems that are compatible with launch on a medium-class rocket toward any one of several targets. It would also have payload capacity to spare for a co-manifested mission, as was done with NASA's Lunar Reconnaissance Orbiter\/LCROSS spacecraft.\"This is a simple, straightforward workhorse of a mission that can launch quickly in 2014, stay within tight cost and schedule constraints and return the necessary data, for less than the cost of a low-risk Discovery-class mission,\" Cheng says. \"It can provide the critical capability NASA needs for the Exploration Systems Mission Directorate\u2019s new robotic-precursor exploration program even when budgets for such missions are being severely cut.\"The project has also captured the spirit of NASA's Summer of Innovation, with interns at APL playing a key role in the Next Gen NEAR study. Challenged to design an asteroid mission on a capped budget and tight schedule, 15 college interns worked with senior engineers and scientists from APL, GSFC and JSC in the APL concurrent engineering design center. Their innovative mission and spacecraft concepts contributed to Next Gen NEAR. \"The experience and results of this study are a win-win for all stakeholders,\" says Dr. Robert Gold, APL Space Department chief technologist and NEAR mission payload manager.\"Everybody was fired up to work on this project,\" adds Daniel Kelly, the systems engineer on the student team and an aerospace engineering graduate student at the University of Michigan. \"This joint team really clicked.\"NEAR Retrospective: NEAR was the first mission to orbit an asteroid and \u2013 after a comprehensive year-long study that yielded more than 160,000 images and measurements of the geology, composition and geophysics of asteroid 433 Eros \u2013 the first mission to land on an asteroid surface.

If the hab module was covered first in radiation tiles then with heat tiles (reentrys) then there wouldn't be any point in 'evacuating' to another module for safety reasons.Which brings me to point 1;The hab module (for effective use of resources) will both be a hab module in space, and on Mars. So it will have to be able to carry itself to Mars surface surviving reentry. ( Like Urwumpe's post a while back, Apollo style, though with heat shield and\/or para-shoot of some sort) will also have to come back to Earth for another reentry. Because of Earths higher gravity, a powered descent stage is unlikely, so a splashdown is best.Which brings me to the point, the hab module is going to make a powered landing on Mars, and reenter to Earth. Unlikly that it will be able to carry the food for astronautics for the duration of the stay and be able to land safely after reentry on Earth with so much cargo weight ( of whatever rock we bring back) so I think separate reentry are needed. Perhaps use our own HCV (modify requirements of vessel)?That also brings me to point 2;Food. -Or are we going that far in details?Trying to find some stats on average consumption (in weight) I found about 400 kg\/person\/year.

If you can refuel the SSTO and go to the moon, why not develop a TSTO that can be refueled in orbit and also go to the moon. Surely it would have the advantage of being a smaller mass being sent to the moon?Which then begs another question, how would you get the fuel up there in the first place?\n\nGood question, which reminded me of another interesting fact. The explanation involves the concept ofdelta-v, which is the increase in velocity a rocket stage can impart. Note: a related but not quite the same use of the term is how much of a velocity change is required to complete a certain mission. For instance you'll see a phrase like the \"delta-v to orbit is about 9,200 m\/s.\"Now for a two stage to orbit vehicle typically the largest delta-v is imparted by the upper stage at around 6,000 m\/s, with the lower stage giving a smaller amount, around 3,000 m\/s. Now, take a look at this diagram that give the delta-v requirements for getting to and from the Moon:Delta-v budget.Earth\u2013Moon space \u2014 high thrusthttp:\/\/en.wikipedia.org\/wiki\/Delta-v_budget#Earth.E2.80.93Moon_space_.E2.80.94_high_thrustIf you add up the delta-v required to get from LEO to the Moon and back again it's around 8,700 m\/s. Note this is less than the delta-v needed to get to LEO.However, it is true that the delta-v a stage can impart is dependent on how much payload it is carrying. So for instance aCentaur upper stagecan be used on an Atlas V rocket or Delta IV rocket to carry a 10mT or 20mT payload to orbit. But it would not have enough delta-v if refueled in orbit to carry the same size payload to the Moon and back according to the amount of delta-v required for such a mission.But if you wanted it to do this for a much smaller payload, it could. You can calculate that it could carry a bit more than 1 mT to the Moon and back if refueled in LEO. This would be useful for robotic missions to carry a robotic lander to the Moon to pick up samples to return to Earth. This would be useful for prospector missions. Note also since the delta-v to some near Earth asteroids is even less than that to the Moon, this could also be useful for prospector missions to some NEO's.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.651175936Z", "author": "Columbia42", "date": "2010-06-11T16:04:57+0100", "id": "e35f8a3ee91f0aff7d4e97c91fa09cc4", "post_id": "post-221040", "text": "Bloodworth said:The problem with the Apollo LM is that the engines are nowhere near powerful enough to keep the vehicle from becoming a small smoking hole on the surface of mars.

The target crater spans 96 miles (154 kilometers) in diameter and holds a mountain rising higher from the crater floor than Mount Rainier rises above Seattle. Gale is about the combined area of Connecticut and Rhode Island. Layering in the mound suggests it is the surviving remnant of an extensive sequence of deposits. The crater is named for Australian astronomer Walter F. Gale.\"Mars is firmly in our sights,\" said NASA Administrator Charles Bolden. \"Curiosity not only will return a wealth of important science data, but it will serve as a precursor mission for human exploration to the Red Planet.\"During a prime mission lasting one Martian year -- nearly two Earth years -- researchers will use the rover's tools to study whether the landing region had favorable environmental conditions for supporting microbial life and for preserving clues about whether life ever existed.\"Scientists identified Gale as their top choice to pursue the ambitious goals of this new rover mission,\" said Jim Green, director for the Planetary Science Division at NASA Headquarters in Washington. \"The site offers a visually dramatic landscape and also great potential for significant science findings.\"In 2006, more than 100 scientists began to consider about 30 potential landing sites during worldwide workshops. Four candidates were selected in 2008. An abundance of targeted images enabled thorough analysis of the safety concerns and scientific attractions of each site. A team of senior NASA science officials then conducted a detailed review and unanimously agreed to move forward with the MSL Science Team's recommendation.

It turns out you don't even need the engines to be of particularly high efficiency.SpaceX is moving rapidly towards testing its Grasshopper scaled-down version of a reusable Falcon 9 first stage:Reusable rocket prototype almost ready for first liftoff.BY STEPHEN CLARKSPACEFLIGHT NOWPosted: July 9, 2012http:\/\/www.spaceflightnow.com\/news\/n1207\/10grasshopper\/SpaceX deserves kudos for achieving a highly weight optimized Falcon 9 first stage at a 20 to 1 mass ratio. However, the Merlin 1C engine has an Isp no better than the engines we had in the early sixties at 304 s, and the Merlin 1D is only slightly better on the Isp scale at 310 s. This is well below the highest efficiency kerosene engines (Russian) we have now whose Isp's are in the 330's. So I thought that closed the door on the Falcon 9 first stage being SSTO.However, I was surprised when I did the calculation that because of the Merlin 1D's lower weight the Falcon 9 first stage could indeed be SSTO. I'll use the Falcon 9 specifications estimated by GW Johnson, a former rocket engineer, now math professor:WEDNESDAY, DECEMBER 14, 2011Reusability in Launch Rockets.http:\/\/exrocketman.blogspot.com\/2011\/12\/reusability-in-launch-rockets.htmlThe first stage propellant load is given as 553,000 lbs, 250,000 kg, and the dry weight as 30,000 lbs, 13,600 kg. The Merlin 1C mass hasn't been released, but I'll estimate it as 650 kg, from its reported thrust and thrust\/weight ratio. The Merlin 1D mass has been estimated to be 450 kg. Then on replacing the 1C with the 1D we save 9*200 = 1,800kg from the dry weight to bring it to 11,800 kg.The required delta v to orbit is frequently estimated as 30,000 feet per second for kerosene-fueled vehicles, 9,144 m\/s. When calculating the delta v your rocket can achieve, you can just use your engines vacuum Isp since the loss of Isp at sea level is taken into account in the 30,000 fps number. Then this version of the Falcon 9 first stage could lift 1,200 kg to orbit:310*9.81ln(1 + 250\/(11.8 + 1.2)) = 9,145 m\/s.Then the Falcon 9 first stage could serve as a proof of principle SSTO on the switch to the Merlin 1D engine.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.67857536Z", "author": "Urwumpe", "date": "2008-11-04T23:09:17+0000", "id": "b2e547439772bfabce405bf08b7dd6e4", "post_id": "post-69146", "text": "DaveS said:I remember reading about it.

Instead of serious calculations, people need to discuss the most basic form of the rocket equation, without any of the really needed extensions to it. What goes on here? If the thread is about pushing the ISS into Mars orbit, we can be done in 25 seconds, write the scenario and be done with it. Sorry, I feel the focus of landing on Mars is completely lost to making screen shots and naming contests of a spacecraft, of which we still don't know, what we expect of it. I can't believe that a week had to pass, without any progress towards Mars, but with a lot of red tape being handed around. I can already see NASA landing on Mars before we have decided if we should paint the floor grass-green or mars-red. That is *garble*, absolutely *garble*.\n\nIs that my fault? Urwumpe, look at who is exactly on this little project here. How many of them are addon devs? Counting from the social group, 2 good quality devs, + me(at about average skill dev)...NASA = 100% engineers at 40 hours a week + budget = progressOF = less than 1% can code like Artlav or you (counting the 700 some odd people that actually have 10 posts or more, not the 3,213 people that are < 10)There is a fuzzy line between realistic and unrealisticThere is a fuzzy line between work and fun.There is a thick hard line between possible and impossible.What some might consider realistic is pure bogus for others. Some developing might be considered fun for some, would be a job for others.For this project, the question becomes how to balance realistic and possible and being fun while using Orbiter for the simulator? Keep in mind the number of engineers and addon dev volunteers for this project...:rolleyes:Right now, for this project anyway, it would be impossible to create a realistic vessel using this crowd within any feasible timeframe. Given a year maybe I could pull together something worth anything, but till then.I think the MSS was created only for the reason of having something to do because, 1. no feasible realistic lander:)cough: arrow, :cough:), 2. sending a few modules into space, ship to Mars, deorbit some vessels, walk around a bit, return.... I think some of us have been there, done that. I have by myself already did that in a few hours. At least trying to send a larger mass to Mars would provide some pseudo-complexity.Wanna scrap the MSS? OK great, now then the mission boils down to, moving Arrow to mars, deorbit, walk around a bit..... :dry:Dont like the Arrow? OK great, now the mission boils down to making something that will work, any volunteers? :tumbleweed:(I hope I am one of those 1%...)Urwumpe said:Especially, even considering to your advantage that most people here have no university education on manned space mission design, I still feel that we have one day of discussion for just 5 minutes of using a pocket calculator.

I left away an airlock from the current \"sketch\" of them, because it might make sense to not have one, but instead either have a tent-like airlock that gets installed additionally, and later connect the green houses to nodes and tunnels that permit entering the green houses without EVA.Since the greenhouses would be \"pretty\" light it would be possible to relocate them by astronaut power. I calculate with 2 greenhouses per astronaut.The hab\/command would be between 4 and 6 levels high, with the lowest full level containing airlocks and rover garage. The lowest level below the rover garage would contain support gear, like waste tanks, batteries, etc. and is only partially pressurized. the next levels would contain workshops, laboratories, crew quarters and the base command center\/communication on the top level, including astronomical gear, that could be used during Mars transit for navigation.Later extensions would be either using the same hull as the Hab\/Command module, or be cylindrical modules of smaller diameter, that will be dug below mars soil.The idea is to make the base slowly look more and more like Olympus is in Orbiter already.", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:05.528957696Z", "author": "dre120v", "date": "2010-05-03T05:15:12+0100", "id": "002550d10b2628460fa914f868142df2", "post_id": "post-220069", "text": "Also:http:\/\/www.nasa.gov\/mission_pages\/station\/expeditions\/expedition23\/p37_launch.html", "thread_id": 14076 }, { "@timestamp": "2023-09-14T07:13:36.049635072Z", "author": "Codz", "date": "2011-11-26T12:31:44+0000", "id": "fc30cf5f718f8c23ae246ebc33303ce3", "post_id": "post-251240", "text": "Coverage started.", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.555678464Z", "author": "RGClark", "date": "2012-01-03T11:00:57+0000", "id": "8370a943c5fb4b0d04c42b65be889d35", "post_id": "post-220313", "text": "Hlynkacg said:Annecdote does not equal data.SpaceX was able to cut developement and launch costs by designing thier program by desinging their prgram to minimize overhead.

I hope you can get somewhere with it.Wishbone said:EDIT #2: Whatever the PMIs are, paddles have to be continuously controlled to achieve desired torque (to end the roll and then to maintain a given attitude). By the way, my attempt to steer it from the Lua console ended in a CTD... pretty sure I got the arguments wrong.\n\nI'm totally ignorant of how Lua interfaces with vessel .dll's, but I tried not to change any of Martin's original code, so if Lua works with the original SolarSail, it should work with SolarSailEx.Wishbone said:Think that having to control paddles is slightly inconvenient. Currently I use Sceneditor to vary attitude to get the most Prograde and outward force. Maybe the process can be automated (with conjugate gradient maximization of the rate of growth of SMa), and only after that can we think of using paddles to get to that attitude. Just my 2 cents.\n\nWould be very cool to have some kind of attitude autopilot.Like low-thrust ion drive spacecraft, solar-sail missions to other planets can be quite long duration. So, I was thinking of implementing a \"high time acceleration attitude-hold\" function (for use with time accel >100x), similar to those I did for Smart-1 or Dawn add-ons (required attitude is calculated and set mathematically). I reckoned a \"maintain sun-angle\" function, together with \"maintain maximum prograde\/retrograde thrust angle\" functions, would be useful.A more sophisticated\/elegant\/realistic solution would be most welcome!Wishbone said:Wonder if a GaAs solar panel and a CMG would be better for attitude control...

Even Antares lifts more payload, at roughly half the takeoff mass.It really puts the advantages of staging in perspective; for only about 20% increase in mass, you get an overfive-foldincrease in payload. And if the first stage truly is the majority of the launch cost, you won't get much of an increase in cost either.If SSTO were as advantageous, and as possible to make happen with SpaceX hardware, as you make it out to be, then SpaceX would be actively pursuing SSTO vehicles. All indications are that they aren't. It doesn't make sense.And being able to recover a stage from F9 staging velocity and from orbit are two very,verydifferent things. If you tried that with the F9 first stage, you would end up adding a lot of mass to the stage- obliterating your payload and probably the ability to make orbit altogether.You also wouldn't be able to deliver payloads to higher orbits, which is a big part of the launch market.", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.495863552Z", "author": "orb", "date": "2010-09-01T14:45:56+0100", "id": "ecdf97cf61f4c2af8a626e883d5954da", "post_id": "post-252692", "text": "O-F Staff Note: Moved to Off-topic.", "thread_id": 16320 }, { "@timestamp": "2023-09-14T07:13:05.6559936Z", "author": "Tex", "date": "2010-06-14T22:47:55+0100", "id": "b2284ce908ab0d0914a0c74c3cf96e76", "post_id": "post-221088", "text": "Good work mate:cheers:", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:05.618071296Z", "author": "Columbia42", "date": "2010-05-09T21:53:57+0100", "id": "487f8ce76fdcf65622d7053d0f82bd1e", "post_id": "post-220768", "text": "Awesome ship!

Proper pinhole camera photography is eventually going to go away.\n\nNot so fast. Film is not the big consumer item it once was, but it's going strong among the art photography crowd and companies are even releasing new products. The Agfa brand name has been ressurected, new printing papers are being introduced. Even as Kodak filed for bankruptcy they announced that despite discontintuing lots of stuff, Tri-X film and chemicals are still making money. Go look athttp:\/\/freestylephoto.biz\/for an example of the cool new stuff coming out.Now the down side is that it's a lot harder to find someone to process your film and make prints since photo labs are closing. Drugstores still process C-41 film in their machines, though. If you're a serious film user you'll have to have a home dark room, which is nothing new.It's also a little harder to find new film cameras. Canon and Nikon still make student model 35mm SLRs, but the raft of fancy consumer gear we used to see is no more. Toy cameras like Holgas and Dianas are popular, and if you got money and want to go medium format, you can still buy a Leica M7 or a Hasselblad, and Fujifilm recently released two really nice new 120-film cameras. Large format film cameras are still selling and probably will as they have always been niche items. And Fujifilm makes Polaroid-style instant film in large format. In fact, the Impossible Project is a company run by former Polaroid employees who are recreating Polaroid film for sale to the art photo world.And if all else fails, you can build your own stuff and mix your own chemicals.

Instead of serious calculations, people need to discuss the most basic form of the rocket equation, without any of the really needed extensions to it. What goes on here? If the thread is about pushing the ISS into Mars orbit, we can be done in 25 seconds, write the scenario and be done with it.

I can already see NASA landing on Mars before we have decided if we should paint the floor grass-green or mars-red.

Aerobraking has the benefit of allowing more payload mass, so long as the heat shield isn't larger than the fuel required to stop, as well.:)\n\nYes think of it this way, if we have 98,900kg absolute maximum, with only a single tank load, that is much less than a single payload from the Ares V. So what is that, like 4 modules space shuttle sized?Note: after a quick check, if we load a AresV full of fuel (160,000kg) onto the MSS, we can jump our payload up to 484,474kg.Which makes me think, how long of a burn would it take for so much fuel?Reversing Specific impulse equation:[math]1500000\/9.18 = 1797.38 * \\frac{42000+160000}{\\bigtriangleup t} [\/math][math] ~90.91 = \\frac{202000}{\\bigtriangleup t} [\/math]which turns to ~2221.98 seconds or 37.03 minutes.

Programming will originate from Mission Control at NASA's Jet Propulsion Laboratory's (JPL) in Pasadena, Calif. The rover is on a precise course for a landing beside a Martian mountain to begin 2 years of unprecedented scientific detective work.\"In the city that never sleeps, the historic Times Square will be the place for New Yorkers to participate in this historic landing,\" said John Grunsfeld, associate administrator for NASA's Science Mission Directorate. \"When you think of all the big news events in history, you think of Times Square, and I can think of no better venue to celebrate this news-making event on Mars.\"Getting Curiosity to the surface of Mars will not be easy. During a critical period lasting only about 7 minutes, the MSL spacecraft carrying Curiosity must slow down from about 13,200 mph (about 5,900 meters per second) to allow the rover to land on the surface at about 1.7 mph (three-fourths of a meter per second). For the landing to succeed, hundreds of events will need to go right, many with split-second timing. All are controlled autonomously by the spacecraft.Prominently positioned below the world-famous New Year's Eve ball in Times Square, the Toshiba Vision dual LED screens will allow viewers to see the action from Mission Control, including receipt of the first signal from Mars following a successful landing. \"We're pleased the Toshiba Vision screens will offer a unique view of this great scientific achievement, the landing of the rover Curiosity on Mars,\" says Eddie Temistokle, senior manager of corporate communications and corporate social responsibility for Toshiba America Inc.Visitors to Times Square can hear the audio portion of NASA's coverage along with other listeners around the world by tuning in to the online radio station Third Rock Radio. This is the first time Third Rock Radio will provide live coverage of a NASA event. Third Rock Radio can be streamed from the NASA homepage at and on smart phones and tablets through the Tuneln mobile app.In the first several weeks after landing, JPL mission controllers will put the rover through a series of checkouts and activities to characterize its performance on Mars while gradually ramping up scientific investigations. Curiosity then will begin investigating whether an area with a wet history inside Mars' Gale Crater ever has offered an environment favorable for microbial life.{...}SPACE.com:NASA to Broadcast Mars Rover Landing From NYC's Times Square Sunday NightDiscovery News:Mars Rover Curiosity Makes it to Times SquareUniverse Today:What Will Curiosity\u2019s \u201cView\u201d Be as it Approaches the Red Planet?Join Universe Today\u2019s Live Webcast of the Curiosity Rover Landing", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:04.82222336Z", "author": "Ghostrider", "date": "2010-04-28T20:55:25+0100", "id": "b4c60036886fd080d96873f6df8e648f", "post_id": "post-219409", "text": "I for one welcome our new redhead, Catholic skeptic gun-toting pathologist black lace lingerie-wearing overladies.", "thread_id": 14015 }, { "@timestamp": "2023-09-14T07:13:05.664653056Z", "author": "Pablo49", "date": "2010-05-04T22:08:17+0100", "id": "18bf86827a6a12e6f38f9741a4420f9a", "post_id": "post-220644", "text": "I think we should go the miner route, where we produce fuel cargo.", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:35.989692928Z", "author": "RGClark", "date": "2012-08-22T03:43:46+0100", "id": "f5d14b21c8343aa33bdc35826753a6d5", "post_id": "post-251851", "text": "Screamer7 said:Now that is very interesting.Is that data what they expected?\n\nI believe also Spirit and Opportunity showed above freezing daytime surface temperatures and above triple point (6.1 millibars) pressure readings.Bob Clark", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.089855232Z", "author": "Izack", "date": "2013-12-17T02:34:03+0000", "id": "64cae077be84181bd011550de2e1da5f", "post_id": "post-219587", "text": "What exactly is this effect, other than the underexposure?", "thread_id": 14022 }, { "@timestamp": "2023-09-14T07:13:05.14169344Z", "author": "AtlantisOnline", "date": "2010-04-30T00:14:55+0100", "id": "e0f408d0093eabea0bf55cf3d90ae66f", "post_id": "post-219639", "text": "Version 4.3 doesn't have them.

This should provide enough thrust at liftoff to adequately lift the vehicle.Assuming an engine mass of 6600 kilograms for the RS-68 engines, this is a total mass of 19 800 kg for the RS-68 engines, and a total mass of 3177 kilograms for the SSME. We will suggest that 50% of the engine mounting structure is jettisoned with the RS-68 engine cluster, and 50% remains fixed to the vehicle. We will not consider staging systems or disconnectable fluid transfer systems, as the original mass of the ET already includes these (for the Orbiter Vehicle).This leads to a dry mass of 53 077 kilograms.We will break launch into three phases:1. 2000 m\/s of dV, all engines, sea-level ISP figures.2. 1000 m\/s of dV, all engines, vacuum ISP figures.3. 7000 m\/s of dV, SSME only, vacuum ISP figures.With these figures, it seems like the vehicle could make it to orbit using under 345 tons of its propellant only. It must be noted, however, that for phases 1 and 2 the exhaust velocity was based on the individual exhaust velocity of all engines, averaged together, and did not take into account any relationship with mass flow. Any wisdom regarding calculating the effective average exhaust velocity of different engines operating together would be much appreciated.For 20 tons, the vehicle would use around 570 tons of its propellant to get to orbit.For a payload of 30 tons, under 650 tons of the propellant would be used to get to orbit; 30 250 kilograms or so seems to be the total limit.With a 10 ton fairing, a 3 ton payload interface and a 23 ton payload, it seems as if the vehicle could reach orbit using only around 595 tons of its propellant. The upper limit for payload at these figures is presumably slightly higher than 23 tons.Assuming that the RS-68 engines each have a cost of $15 million, the SSME has a cost of $50 million, the rest of the hardware has the same cost of $60 million, and the additional hardware (fairings, etc) add $10 million, then the vehicle would have a cost to LEO of under $7200\/kg, based onhardware cost aloneand not including other factors. While this is not magic-$100-low, and isn't even exceptionally-realistic low, it is perhaps approaching modern US launchers, and is at least on a par with the lowest cost estimates of STS.As for acceleration, with the RS-68 engines still attached and working off lowest throttle settings at vacuum thrust, the vehicle will reach 4G when it masses in total around 190 tons. The minimum acceleration that the vehicle would experience just before MECO, would be just under 2 G at minimum thrust from the SSME; at maximum thrust, it would be under 3G.Obviously you would want to dump the engine package as soon as it is not needed. Of course, this is just one arrangement, you could maybe have two engines staying with the vehicle, for example.Another option might be to change the type of engine- using the RS-68B as a compromise between the RS-68 and the SSME, still costing far less than the SSME.This is all just hot air, of course; a far better experiment would be to try this concept out in Orbiter.It is important to note that engines account for roughly 30% of of the dry mass of the vehicle at launch, minus payload, and would comprise an even larger amount of the mass of the vehicle with optimised propellant tanks.Parachuting, recovering, shipping, refurbishing, and stacking an engine module could be easier and cheaper than doing the same with a flimsy propellant tank.

It will do so on the surface of Mars, where there has never before been such an instrument, as well as during the trip between Mars and Earth.Radiation Assessment Detector for Mars Science Laboratory\u200bRAD's measurements on Mars will help fulfill the mission's key goals of assessing whether Curiosity's landing region on Mars has had conditions favorable for life and for preserving evidence about life. This instrument also will do an additional job. Unlike any of the nine others in this robotic mission's science payload, RAD has a special task and funding from the part of NASA that is planning human exploration beyond Earth orbit. It will aid design of human missions by reducing uncertainty about how much shielding from radiation future astronauts will need. The measurements between Earth and Mars, as well as the measurements on Mars, will serve that purpose.\"No one has fully characterized the radiation environment on the surface of another planet. If we want to send humans there, we need to do that,\" said RAD Principal Investigator Don Hassler of the Boulder, Colo., branch of the Southwest Research Institute.Whether the first destination for human exploration beyond the moon is an asteroid or Mars, the travelers will need protection from the radiation environment in interplanetary space. Hassler said, \"The measurements we get during the cruise from Earth to Mars will help map the distribution of radiation throughout the solar system and be useful in mission design for wherever we send astronauts.\"RAD will monitor high-energy atomic and subatomic particles coming from the sun, from distant supernovas and from other sources. These particles constitute the radiation that could be harmful to any microbes near the surface of Mars or to astronauts on a Mars mission. Galactic cosmic rays, coming from supernova explosions and other events extremely far from our own solar system, are a variable shower of charged particles. In addition, the sun itself spews electrons, protons and heavier ions in \"solar particle events\" fed by solar flares and ejections of matter from the sun's corona. Astronauts might need to move into havens with extra shielding on an interplanetary spacecraft or on Mars during solar particle events.Earth's magnetic field and atmosphere provide effective shielding for our home planet against the possible deadly effects of galactic cosmic rays and solar particle events. Mars, though, lacks a global magnetic field and has only about one percent as much atmosphere as Earth. Just to find high-enough radiation levels on Earth for checking and calibrating RAD, the instrument team needed to put it inside major particle-accelerator research facilities in the United States, Europe, Japan and South Africa.An instrument on NASA's Mars Odyssey orbiter, which reached Mars in 2001, assessed radiation levels above the Martian atmosphere. Current estimates of the radiation environment at the planet's surface rely on modeling of how the thin atmosphere affects the energetic particles, but uncertainty in the modeling remains large. \"A single energetic particle hitting the top of the atmosphere can break up into many particles -- a cascade of lower-energy particles that might be more damaging to life than a single high-energy particle,\" Hassler noted.The 1.7-kilogram (3.8-pound) RAD instrument has an upward-pointing, wide-angle telescope with detectors for charged particles with masses up to that of iron. It can also detect secondary neutrons coming from both the Mars atmosphere above and Mars surface material below. Hassler's international RAD team includes experts in instrument design, astronaut safety, atmospheric science, geology and other fields.Southwest Research Institute, in Boulder and in San Antonio, Texas, and Christian Albrechts University, in Kiel, Germany, built RAD with funding from the NASA Exploration Systems Mission Directorate and Germany's national aerospace research center: Deutschen Zentrum f\u00fcr Luft- und Raumfahrt. The team assembling and testing the Mars Science Laboratory spacecraft at NASA's Jet Propulsion Laboratory in Pasadena, Calif., installed RAD onto Curiosity last month for the late-2011 launch.RAD measurements during the trip from Earth to Mars will enable correlations with instruments on other spacecraft that monitor solar particle events and galactic cosmic rays in Earth's neighborhood, then will yield data about the radiation environment farther from Earth.Once on Mars, the rover's prime mission will last a full Martian year -- nearly two Earth years. A one-time set of measurements by RAD would not suffice for determining the radiation environment on the surface, because radiation levels vary on time frames both longer than a year and shorter than an hour. Operational planning for Curiosity anticipates that RAD will record measurements for 15 minutes of every hour throughout the prime mission.Radiation levels probably make the surface of modern Mars inhospitable for microbial life. The measurements from RAD will feed calculations of how deeply a possible future robot on a life-detection mission might need to dig or drill to reach a microbial safe zone. For assessing whether the surface radiation environment could have been hospitable for microbes in Mars' distant past, researchers will combine RAD's measurements with estimates of how the activity of the sun and the atmosphere of Mars have changed in the past few billion years.\"The primary science goal of Curiosity is to determine whether its landing site is, or ever was, a habitable environment, a place friendly to life,\" said JPL's Ashwin Vasavada, deputy project scientist for the Mars Science Laboratory. \"That involves looking both for conditions that would support life as well as for those that would be hazardous to life or its chemical predecessors. Natural, high-energy radiation is just such a hazard, and RAD will give us the first look at the present level of this radiation and help us to better estimate radiation levels throughout Mars' history.\"JPL, a division of the California Institute of Technology in Pasadena, manages the Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington.

That is not the case. In fact it is easy, IF you do it in the right way. The right way is summarized in thatonesimple sentence at the end of my sig file.We all know that to get a good payload to space you want a high efficiency engine. And we all know we want to use lightweight structures so the weight savings can go to increased payload. So you would think it would be obvious to use both these ideas to maximize the payload to orbit, right?And indeed both have been used together -for upper stages. Yet this fundamentally obvious concept still has not been used forfirst stages. It is my thesis that if you do this, then what you wind up with will automatically be SSTO capable. This is true for either kerosene fueled or hydrogen fueled stages.Part of the misinformation that has been promulgated is that the mass ratio for SSTO's is some impossible number. This is false. We've had rocket stages with the required mass ratio's since the 60's, nearly 50 years, both for kerosene and hydrogen fueled. Another part of the misinformation is that it would require some unknown high energy fuel and engine to accomplish. This is false. The required engines have existed since the 70's, nearly 40 years, both for kerosene and hydrogen fueled.What has NOT been done is to marry the two concepts together forfirst stages. All you need to do is swap out the low efficiency engines that have been used for the high mass ratio stages and replace them with the high efficiency engines. It really is that simple.This makes possible small, low cost orbital vehicles that could transport the same number of passengers as the space shuttle, about 7, but would have a comparable cost to a mid-sized business jet, a few tens of millions of dollars.Then once you have the SSTO's they make your staged vehicleseven betterbecause you can carry greater payload when they are used for the individual stages of the multi-staged vehicle.In disseminating the false dogma that SSTO's are not possible it is sometimes said instead that they are not practical because the payload fraction is so small. Even this is false. And indeed this is just as damaging as making the false statement they are not possible because the statements are often conflated into meaning the same thing. So when those in the industry make the statement they are not \"practical\", meaning actually they are doable but not economical, this becomes interpreted among many space enthusiasts and even many in the industry as meaning it would require some revolutionary advance to make them possible.The fact that you can carry significant payload to orbit using SSTO's can be easily confirmed by anyone familiar with the rocket equation. To get a SSTO with significant payload using efficient kerosene engines you need a mass ratio of about 20 to 1. And to get a SSTO with significant payload using efficient hydrogen engines you need a mass ratio of about 10 to 1. Both of these the high mass ratio stages and the high efficiency engines for both kerosene and hydrogen have existed for decades now.See this list of rocket stages:Stages Index.http:\/\/www.astronautix.com\/stages\/index.htmAmong the kerosene-fueled stages you see that several among the Atlas and Delta family have the required mass ratio. However, for the early Atlas stages you have to be aware of the type of staging system they used. They had drop-off booster engines and a main central engine, called the sustainer that continued all the way to orbit. But even when you take this into account you see these highly weight optimized stages had surprisingly high mass ratios.See for instance the Atlas Agena SLV-3:Atlas Agena SLV-3Lox\/Kerosene propellant rocket stage.Loaded\/empty mass 117,026\/2,326 kg. Thrust 386.30 kN. Vacuum specific impulse 316 seconds.Cost $ : 14.500 million. Semistage: LR89-5. Semistage Thrust (vac): 1,644.960 kN (369,802 lbf). Semistage Thrust (vac): 167,740 kgf.

But that is only including the sustainer engine. The more relevant ratio would be when you add in the mass of the booster engines to the dry mass since they are required to lift the vehicle off the pad. These are listed as the jettisonable mass at 3,174 kg. This makes the loaded mass now 117,026 + 3,174 = 120,200 and the dry mass 2,326 + 3,174 = 5,500 kg, for a mass ratio of 21.85.But this was using the low efficiency engines available in the early 60's. Let's swap these out for the high efficiencyNK-33. The sustainer engine used was theLR89-5at 720 kg. At 1,220 kg the NK-33 weighs 500 kg more. So removing both the sustainer and booster engines to be replaced by the NK-33 our loaded mass becomes 117,526 kg and the dry mass 2,826 kg, and the mass ratio 41.6 (!).For the trajectory-averaged Isp, notice this is not just the midpoint between the sea level and vacuum value, since most of the flight to orbit is at high altitude at near vacuum conditions. A problem with doing these payload to orbit estimates is the lack of a simple method for getting the average Isp over the flight for an engine, which inhibits people from doing the calculations to realize SSTO is possible and really isn't that hard. I'll use a guesstimate Ed Kyle uses, who is a frequent contributor to NasaSpaceFlight.com and the operator of the Spacelauncereport.com site. Kyle takes theaverage Isp as lying 2\/3rds of the way upfrom the sea level value to the vacuum value. The sea level value of the Isp for the NK-33 is 297 s, and the vacuum value 331 s. Then from this guesstimate the average Isp is 297 + (2\/3)(331 - 297) = 319.667, which I'll round to 320 s.Using this average Isp and a 8,900 m\/s delta-V for a flight to orbit, we can lift 4,200 kg to orbit:320*9.8ln((117,526+4,200)\/(2,826+4,200)) = 8,944 m\/s. This is a payload fraction of 3.5%, comparable to that of many multi-stage rockets.This is just using the engine in its standard configuration, no altitude compensation. However, for a SSTO you definitely would want to use altitude compensation. Dr. Bruce Dunn in his report \"Alternate Propellants for SSTO Launchers\" estimates an average Isp of 338.3 s for high performance kerosene engines when using altitude compensation. Then we could lift 5,500 kg to orbit:338.3*9.8ln((117,526+5,500)\/(2,826+5,500)) = 8,928 m\/s.But kerosene is not the most energetic hydrocarbon fuel you could use. Dunn in his report estimates an average Isp of 352 s for methylacetyene using altitude compensation. This would allow a payload of 6,500 kg : 352*9.8ln((117,526+6,500)\/(2,826+6,500)) = 8,926 m\/s.Bob Clark---------- Post added 06-26-11 at 01:40 PM ---------- Previous post was 06-25-11 at 04:34 PM ----------Because SSTO's are controversial I should make the disclaimer that citing the references in the prior post should not be construed as the cited authors endorsing the viewpoint I expressed in that post.Note also in fact that this SSTO has a very good value for a ratio that I believe should be regarded as a better measure, i.e., figure of merit, than the payload ratio for the efficiency of a orbital vehicle. This is the ratio of the payload to the total dry mass of the vehicle. The reason why this is a good measure is because actually the cost of the propellant is a minor component for the cost of an orbital rocket. The cost is more accurately tracked by the dry mass and the vehicle complexity. Note that SSTO's in not having the complexity of staging are also good on the complexity scale.For the ratio of the payload to dry mass you see this is greater than 1 for this SSTO. This is important because for every orbital vehicle I looked at, and possibly for every one that has existed, this ratio is going in the other direction: the vehicle dry mass is greater than the payload carried. Often it is much greater. For instance for the space shuttle system, the vehicle dry mass is more than 12 times that of the payload.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:35.787218176Z", "author": "Der Zeitgeist", "date": "2012-08-05T20:19:53+0100", "id": "a55b44f2825882ef3b326b6937c87fd4", "post_id": "post-251485", "text": "This \"Eyes on the Solar System\" application from JPL is just amazing.

For a reusable Falcon 9, it is around Mach 6, depending on the mission.\" For the reusable version, the rocket must be traveling at a slower speed at separation because the burn must end early, preserving enough propellant to let the rocket fly back and land vertically. This also makes recovery easier because entry velocities are slower.However, the slower speed also means that the upper stage of the Falcon rocket must supply more of the velocity needed to get to orbit, and that significantly reduces how much payload the rocket can lift into orbit. \"The payload penalty for full and fast reusability versus an expendable version is roughly 40 percent,\" Musk says. \"[But] propellant cost is less than 0.4 percent of the total flight cost. Even taking into account the payload reduction for reusability, the improvement is therefore theoretically over a hundred times.\"\n\nhttp:\/\/www.popularmechanics.com\/sci...musk-on-spacexs-reusable-rocket-plans-6653023Then for the Falcon 9, the payload would be reduced from 10 mT to 6 mT. If the reduction in payload really is this high, then maybe it would be better to recover the first stage at sea. The loss in payload is coming from the reduction in the speed of staging as well as the need to retain a portion of the fuel for the return to base. Recovering at sea would not have these disadvantages because you could let the first stage make its usual trajectory at returning to the sea but use just small amount of propellant for the final slowdown before the sea impact.In this article Musk does mention that returning back to the launch point allows the turnaround time at least for the first stage to be just hours. But will we really need that short a turnaround time at this stage of the game? A turnaround time of a few days would seem to be sufficient.Perhaps the idea that retrieval at sea would be so expensive comes from the experience of the shuttle with the SRB's. But these were quite large and heavy at ca. 90 mT dry compared to that of the Falcon 9 first stage at less than 15 mT. Also, it is well known the labor costs for the shuttle were greatly inflated compared to a privately funded program.The only additional requirement is that you would need a cover that could be extended to cover the engine section and would be watertight.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:35.975452928Z", "author": "Unstung", "date": "2012-08-07T11:03:08+0100", "id": "df2c51ac32ad1cd3eb425858c4102781", "post_id": "post-251745", "text": "N_Molson said:And the first color image from Mars (well, from MSL on Mars) :Weather seems to be a bit dusty today in Hale Crater.:)\n\nThedust coveris still on.Where Curiosity landed:", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.352598272Z", "author": "shangding", "date": "2010-04-28T04:23:29+0100", "id": "52ca060d20697523d3317c8fcfaa0eab", "post_id": "post-219773", "text": "i don't know,may you said the chinese characters isn't chinese.:)like the characters in my picture is just not chinese,i don't know what's that.", "thread_id": 14040 }, { "@timestamp": "2023-09-14T07:13:04.753147904Z", "author": "ex-orbinaut", "date": "2010-04-26T03:22:47+0100", "id": "41fcc0617a3d8922bc11c6e9fa7d14a8", "post_id": "post-219307", "text": "Hi all,A question for those who know about the subject, could you please recommend a reasonable digital camera that films video (with audio) for the price range between 200 - 300 USD?To be more specific, it is the best possible video picture quality for the price that I am after, audio second, and I place no special no emphasis on weather or shock proofing whatsoever.Thanks in advance.Edit:Ah, yes.

For example landing bigger modules on Mars (since we can't inflate it all), would require something along the XR5 from the available vehicles. but the XR5 is already over-sized for all the rest. We have hundreds of station building in LEO vessels or long-range cruisers, but no simple Mars lander.If we use a XR5 in the project, we don't need anything else, this big beast can transport tons to Mars, land large modules and could also be overloaded with UCGO cargo. We would just fly once...and then have nothing to do in space anymore - simply because a XR5 could carry enough cargo to build the first mars base in one, maximal two landings.I would rather have something more specialized for such tasks, for the fun of it.Bj said:About mission windows, while I get they are limiting, what if we dont really go for the 'most fuel efficient manner.' If the stack or any other ship has enough Delta V supply to get to a planet at the most direct, fastest and least efficient possible methods, why not cut out the months of wait and launch imminently? -so long as you have it in the delta V budget of course.\n\nYes, that is why it is called window. The limit of the window is your dV budget, but the required dV approaches the speed of light between the windows.I already calculated it into my statement, when I said that there is a phase for some weeks, where we can haul cargo to Mars or back.

Despite Hydrogen being the lightest variant. A kerosene based version would be heavier than a A380 - if it could fly and reach orbit at all.\n\nWell yes, but what do you expect? It is a space launch vehicle after all, even if it is an SSTO one, you can't expect it to be the size of a fighter jet.Even if you built a TSTO vehicle with a similar payload, it would probably end up being quite big as well.Even the DeltaGlider would need to be larger, if it actually had to carry its propellant mass in liquid hydrogen.Approximately yes, maybe even more. A small drop in ISP means a big change in vehicle mass for the same trajectory.\n\nThat is very understandable, but ISP also does not correlate directly with a certain degree of user-friendliness (though obviously it makes a big difference- the difference between cost of the SSME and RS-68 are an example).Lets define \"user-friendly\" as such: The pilot\/owner\/whoever can do the preflight and post-flight checks himself, and only needs specialist knowledge for dealing with the big problems. if you permit some additional mass penalty for example, you could make it possible for a skilled technician to swap a turbopump assembly, without you needing to hire a specialist team, like for example if you would need for replacing a turbopump rotor or bearing.Current situation in spaceflight is as such: For everything, you need experts, usually in the price class of engineers. You can already do some small maintenance as IVA and EVA, which is about on the skill level for skilled technicians, but it is impossible to fly without. And the problem is not the staging system, but such mundane things like the engines or the propellant utilization system.Calibrating a IMU isn't that complex, you could do that with adequate accuracy without studying physics. But the subsystem has to be designed for this task.Swapping a LRU or installing new software would be fairly easy, providing automated test equipment isn't a problem. But could you for example replace a damaged heavy-duty valve? Not that easy without the valve helping you.Replacing a worn-out bearing on a engine turbopump is really rocket science - not only do you need to deal with complex pneumatics and extreme accuracies, but you also need to do tasks like being able to balance a turbopump shaft afterwards again to prevent destructive vibrations. A high-performance turbopump runs at 250,000 RPM. If you want to be at least effective, you run at 100,000 RPM. if you want it cheap, but bulky, you use just 50,000 RPM and pay a hefty fuel efficiency price. Even for the 50,000 RPM turbopump, you will need to balance the rotor carefully. At 250,000 RPM, you balance in the range of a few hundred nanogram. Special engineers can do that, with special expensive machines. They cost you a few million per rotor then (alone about 400,000 USD for the wages). And you can't make it automatic. You will always need specialists to make sure the machines are not optimizing the rotor away into tiny chips of metal waste. The local optimum for the balance is not always the global optimum that you want.If a spacecraft owner would need to send his spacecraft to a special company every every flight to check for such expensive problems and do the overhaul because even small checks mean disassembling sensitive parts, it is not user-friendly, the user who paid for it will spend less time with his investment as the technicians to maintain it.Even if you want to just attract major companies, you need a low-cost approach to maintenance. Especially since you will have to assume that you are not alone in the world and your design might be the first, but not the last to appear. The first in a market is not always the one who makes the biggest profits.\n\nDo we really need to operate spacecraft as amateurs though? This is what RGClark has stated (or is at least implying), but I can imagine many levels of operation that are not nearly as simple as a very small-scale private operation, that are still much better than the current state(s) of where spaceflight is at.That said, your super-expensive hyper-intensive maintainance operations and accidental metal-chip production machines will come down in price with time... of course there will always be limits and more intensive systems will always cost more, but the more experience is gained, the better things will become.", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.503693568Z", "author": "Urwumpe", "date": "2010-04-30T11:10:21+0100", "id": "00a8a077db8f5f23f97765983f694a39", "post_id": "post-220018", "text": "Has less functions than the German Army Standard hand excavator. this one comes with built in lock-picking, tree-chopping and works also as jack and fire place... and is also a very valuable tool for peace negotiations.", "thread_id": 14073 }, { "@timestamp": "2023-09-14T07:13:36.002306816Z", "author": "orb", "date": "2012-09-19T23:21:29+0100", "id": "fa401da0d935e7975075fe2225dfa419", "post_id": "post-251931", "text": "CBS News Space:Curiosity poised for first 'hands-on' geologyFlorida Today:Curiosity aims to interrogate first Martian rockThe Planetary Society Blog:Curiosity sol 43 update: First science stopDiscovery News:Mars Rover Curiosity Has First Target in Sight", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.600147712Z", "author": "Wally", "date": "2010-05-01T21:35:09+0100", "id": "f71c660307e9911464e3320287a4d294", "post_id": "post-220516", "text": "I've noticed that RCS behavior for Shuttle Ultra mimics the RCS for the real shuttle, meaning a pulse mode for RCS burns (as seen and heard [nomedia=\"http:\/\/www.youtube.com\/watch?v=v4uZeeUWrU0\"]YouTube- STS-125 Atlantis Hubble SM4 - Hubble Release [HD][\/nomedia]).

There is ABSOLUTELY no reason why a single piece ultrawidescreen monitor should cost more than that. It would be a normal flat panel LCD in every way, except the screen would be long. And if there there was one for $700 I would buy it at once. There is NO reason why these things should cost $6,500. A 70 inch plasma screen doesn't cost that much...\n\nBecause manufacturing curved screens is a whole lot more expensive than manufacturing flat ones, and it's a lot higher pixel pitch than the 70\" screen you point out. The more pixels you're manufacturing on a single panel, the more likely you are to run into manufacturing defects, and the more expensive it gets.Keatah said:I still have to disagree, if I look left then I see perhaps a wall or the hallway or bookcase. I am certainly not looking at a monitor. So if trackIR shows me something and I'm not looking that way, what's the point. I ain't gonna see it!\n\nHave you actuallyuseda TrackIR? Judging by your comments, I suspect not.Are your eyes glued straight forward in your sockets?The TrackIR will amplify the angle of your head movement quite a bit (and you can configure by how much. For me, I have it set so that turning my head to point at the edge of my monitor--5-10 degrees--causes about a 90 degree change in the view on screen. Only a few more degrees takes the view all the way to 180). Again, I wear glasses, which restricts my usable forward field of view, but I have absolutely no trouble keeping my eyes focused on the center of the screen while I turn my head a few degrees.Sure, it lets you get a bouncy view with a slightly different perspective. But that's about it.\n\nThis comment alone makes be pretty sure that you've never used one. It gives you far more than \"a bouncy view with a slightly different perspective.\" It gives you the ability to look around your cockpit in a very natural way, directly controlling where you look by the direction you turn your head, without needing to fiddle with the hat switch.It is a concept product, that, when refined, may be useful and fun.. Meantime to all you beta-testers out there! Let's get purchasing the next version and keep it up!!\n\nIt already is useful and fun. If you haven't used one, I strongly recommend finding someone who has one and getting them to let you borrow it and try it out. Now that I've used one, I can't live without it when simming--it very quickly becomes second nature. And, like I said--I had the conscious choice between using multiple monitors and using a TrackIR, and I picked the TrackIR, and would repeat that choice any day. The TrackIR allows you to look inanydirection, which is amazing for flying anything that isn't an airliner.With three monitors, your field of view is still limited to a narrow band in front of and slightly to the sides, with no ability to look \"up\" during aerobatic maneuvers to see where you're going without resorting to the unnatural and clunky hat switch.River Crab said:Also, I think TrackIR is an incredible ripoff as well. Such a thing is possible for, at most, $50 USD, using free software (FreeTrack), a Wii remote, cheap DIY tracking clip, and Bluetooth adapter. I'm actually very surprised that this guy built that whole thing, and yet, just bought a TrackIR.I think he either didn't know about it, or ran out of Coffee.:coffee:\n\nI'd guess you haven't used one either? TrackIR has overall higher quality, more options, and is better supported than FreeTrack. When it comes to how much he's saving, saving tens of thousands of dollars on a DIY motion rig in exchange for lots of time building makes perfect sense. Saving a mere $100 isn't worth the added work and reduced quality.It's also possible that he already owned the TrackIR (wouldn't surprise me to learn that someone who would go to this much trouble for a simpit already owned one), so it didn't cost him anything for this project. This is also suggested by the fact that he's using the older passive hat-tracking device and not the newer active one which is more accurate (and doesn't cost much at all).", "thread_id": 16280 }, { "@timestamp": "2023-09-14T07:13:05.651374592Z", "author": "Voyager", "date": "2010-06-11T16:16:11+0100", "id": "7c301aac3d10ba5f8a4c9d2d2949ca6b", "post_id": "post-221042", "text": "Perhaps, we could launch a scouting mission to find where we are going to set up the base.

But then you also have to add on the thrust structure which transmits the thrust evenly to the propellant tanks, the wiring, and the hydraulics for the engine gimbaling. You also have to add on the avionics but you would have to add this also to the S-II, and with modern miniaturization this should be a small component of the empty weight.These extra weight considerations are why I prefer to do this swapping out of engines with already existing stages, such as the S-II.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.555039232Z", "author": "T.Neo", "date": "2012-01-02T18:32:09+0000", "id": "53d4463fe635d8203d72b47b49dce877", "post_id": "post-220303", "text": "Good.

There is also the fact this would not be for making a profit on the power production as with uranium mines but just for producing propellant.\n\nExcept, if you're aiming for a profit, you have to make that profit somehow. If you just add uranium production for nuclear rockets to the chain, it doesn't help- it makes it worse.It isn't a viable operation. Not nearly. Not even with $100\/kg. If you had $100\/kg, you'd be better off educating people and just shipping a reactor to the Moon instead!I'll show in an upcoming post you can make a small SSTO using currently existing engines and stages about the size of the smallest of the very light or personal jets:\n\nErOne thing I've learnt is that you can't just ascribe maths to everything. Well, technically you can, but you always have to realise the engineering limitations, for example.And the other thing is that you need to add mass to create a spacecraft. You need seperate power generation systems. You need an RCS. You need thermal control and a TPS for reentry!You would add literally tons to your vehicle.You can't have a fighter-jet sized SSTO, even with nuclear propulsion. I realised this when I did ROCS. I knew it was going to be large potentially larger than STS- but I didn't exactly know how large. If I used LH2 as propellant, it would have been absolutely huge.This is for a spacecraft supposed to carry six people and 4 tons of cargo to LEO. I believe it was somewhere around 70 meters long by the end of it.In your calculations, you would need a very large vehicle (Think of Skylon, which isn't small at all), with very complex and maintenance heavy engines.\n\nSkylon is large just in dimensional terms because it uses LH2 as fuel. You could make the vehicle a good deal smaller if you used something like methane, but you would of course take a performance hit...you could either haul two second stages with a vehicle of the size of the Skylon (and very expensive technology) or a single second stage with more user-friendly hardware\n\nDo you really have to slash your performance by half to get 'more user-friendly hardware'?What is the cutoff point for 'user-friendly'? How user friendly do you have to be?

This is not true of TSTO's where the upper stage might only get, say, a delta-v of 6,000 m\/s.So if one did have his own private, SSTO vehicle, then with propellant depots he would also have his own private lunar vehicle.See discussion here:SSTO's would have made possible Arthur C.

Careful inspection of the tracks reveals a unique, repeating pattern, which the rover can use as a visual reference to drive more accurately in barren terrain. The pattern is Morse code for JPL, the abbreviation for NASA's Jet Propulsion Laboratory in Pasadena, Calif., where the rover was designed and built, and the mission is managed.\"The purpose of the pattern is to create features in the terrain that can be used to visually measure the precise distance between drives,\" said Matt Heverly, the lead rover driver for Curiosity at JPL.{colsp=3}Click on images for details\u200b||Curiosity Leaves Its Mark\u200bThis image shows a close-up of track marks from the first test drive of NASA's Curiosity rover.Image credit: NASA\/JPL-Caltech\u200b|Reading the Rover's Tracks\u200bThe straight lines in Curiosity's zigzag track marks are Morse code for JPL, which is short for NASA's Jet Propulsion Laboratory in Pasadena, Calif., where the rover was built and the mission is managed.|Curiosity Tracks Its Tracks\u200bThis image shows a close-up of track marks left by NASA's Curiosity rover. Holes in the rover's wheels, seen here in this view, leave imprints in the tracks that can be used to help the rover drive more accurately.Image credit: NASA\/JPL-Caltech\u200bThis driving tool, called visual odometry, allows the rover to use images of landscape features to determine if it has traveled as far as predicted, or if its wheels have slipped. For example, when the rover drives on high slopes or across loose soil, it will routinely stop to check its progress. By measuring its distance relative to dozens of prominent features like pebbles or shadows on rocks -- or patterns in its tracks -- the rover can check how much its wheels may have slipped. If Curiosity has not slipped too much, it can then re-plan the next leg of its drive, taking its actual position into account.\"Visual odometry will enable Curiosity to drive more accurately even in high-slip terrains, aiding its science mission by reaching interesting targets in fewer sols, running slip checks to stop before getting too stuck, and enabling precise driving,\" said rover driver Mark Maimone, who led the development of the rover's autonomous driving software.The Morse code imprinted on all six wheels will be particularly handy when the terrain is barren. Curiosity won't be able to read the Morse code symbols in the track marks directly, but it will note that the pattern is a high-contrast feature. This will give the rover the anchor it needs in an otherwise featureless terrain.\"Imagine standing in front of a picket fence, and then closing your eyes and shifting to the side. When you open your eyes, you wouldn't be able to tell how many pickets you passed. If you had one picket that was a different shape though, you could always use that picket as your reference,\" said Heverly. \"With Curiosity, it's a similar problem in featureless terrain like sand dunes. The hole pattern in the wheels gives us one 'big picket' to look at.\"NASA's Mars Exploration rovers Spirit and Opportunity also used visual odometry to ensure accurate driving in difficult terrains. Their wheels had been bolted to their landing platform, leaving holes that left distinguishing marks in their tracks. Those marks proved critical for the visual odometry system on Opportunity when it traversed the relatively featureless terrain at Meridian Planum. Opportunity is still trekking on Mars more than eight years after setting down on the Red Planet.Curiosity likewise has holes in its wheels, only in the shape of Morse code letters.\"Even though Curiosity didn't need to be bolted down, we wanted to have the holes anyway. The mechanical team suggested multiple smaller holes rather than one large one like the Mars Exploration Rovers had, and one earlier design had spelled out letters in a cleat pattern, so I proposed using a Morse code version,\" said Maimone. \"And the rest is history.\"{...}NASA\/ NASA JPL:NASA Curiosity Rover Begins Eastbound Trek on Martian SurfaceAugust 29, 2012PASADENA, Calif. -- NASA's Mars rover Curiosity has set off from its landing vicinity on a trek to a science destination about a quarter mile (400 meters) away, where it may begin using its drill.The rover drove eastward about 52 feet (16 meters) on Tuesday, its 22nd Martian day after landing. This third drive was longer than Curiosity's first two drives combined. The previous drives tested the mobility system and positioned the rover to examine an area scoured by exhaust from one of the Mars Science Laboratory spacecraft engines that placed the rover on the ground.\"This drive really begins our journey toward the first major driving destination, Glenelg, and it's nice to see some Martian soil on our wheels,\" said mission manager Arthur Amador of NASA's Jet Propulsion Laboratory in Pasadena, Calif. \"The drive went beautifully, just as our rover planners designed it.\"{colsp=2}Click on images for details\u200b|Soil clinging to the right middle and rear wheels of NASA's Mars rover Curiosity can be seen in this image taken by the Curiosity's Navigation Camera after the rover's third drive on Mars.Image credit: NASA\/JPL-Caltech\u200b|On Aug. 28, 2012, during the 22nd Martian day, or sol, after landing on Mars, NASA's Curiosity rover drove about 52 feet (16 meters) eastward, the longest drive of the mission so far.Image credit: NASA\/JPL-Caltech\u200bGlenelg is a location where three types of terrain intersect. Curiosity's science team chose it as a likely place to find a first rock target for drilling and analysis.\"We are on our way, though Glenelg is still many weeks away,\" said Curiosity Project Scientist John Grotzinger of the California Institute of Technology in Pasadena. \"We plan to stop for just a day at the location we just reached, but in the next week or so we will make a longer stop.\"During the longer stop at a site still to be determined, Curiosity will test its robotic arm and the contact instruments at the end of the arm. At the location reached Tuesday, Curiosity's Mast Camera (Mastcam) will collect a set of images toward the mission's ultimate driving destination, the lower slope of nearby Mount Sharp. A mosaic of images from the current location will be used along with the Mastcam images of the mountain taken at the spot where Curiosity touched down, Bradbury Landing.

In the example in my prior postifyou had the aerospike nozzle on the Falcon 9 first stage then you could lift a Dragon size capsule.The payload capacity of this reusable SSTO version of the Falcon 9 would be less than a reusable two stage Falcon 9 but you don't want it for lifting large cargo anyway. Both cases would have the operational costs of reusability, but the SSTO version would not have the added purchase costs of the second stage nor its added operational costs.An extensive discussion of the economic benefits of reusable SSTO's is presented in the book:Halfway to Anywhere: Achieving America's Destiny In Space.by G.

The paper describes the basic definition and application of \u2018Cost Engineering\u2019 which means to design a vehicle system for minimum development cost and\/or for minimum operations cost. This is important now and for the future since space transportation has become primarily a commercial business in contrast to the past where it has been mainly a subject of military power and national prestige. Several examples are presented for minimum-cost space launch vehicle configurations, such as increasing vehicle size and\/or the use of less efficient rocket engines in order to reduce development and operations cost.Further a cost comparison is presented on single-stage (SSTO)-vehicles vs. two-stage launchers which shows that SSTOs have lower development and operations cost although they are larger, respectively have a higher lift-off mass than two-stage vehicles with the same performance.The design of a space tourism-dedicated launch vehicle is an extreme challenge for a cost-engineered vehicle design in order to achieve cost per seat not higher than $50 000. Finally an outlook is presented on the different options for manned Earth-to-Moon transportation modes and vehicles \u2013 another most important application of \u2018cost engineering\u2019, taking into account the large cost of such a future venture.http:\/\/faculty.kfupm.edu.sa\/AE\/hmomar\/Air_Launcher_Project\/Cost_Engineering.pdfBob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.49212928Z", "author": "thomasantony", "date": "2008-05-27T14:19:29+0100", "id": "e750f500555dd0f4f1f68375d68a8896", "post_id": "post-69062", "text": "Dr. Ernst Stuhlinger, the German rocket scientist, passed away on May 25, at the age of 94.

Such is the cost of raising an army of 100,000 men.When you engage in actual fighting, if victory is long in coming, then men's weapons will grow dull and their ardor will be damped. If you lay siege to a town, you will exhaust your strength.Again, if the campaign is protracted, the resources of the State will not be equal to the strain.Now, when your weapons are dulled, your ardor damped, your strength exhausted and your treasure spent, other chieftains will spring up to take advantage of your extremity. Then no man, however wise, will be able to avert the consequences that must ensue.Thus, though we have heard of stupid haste in war, cleverness has never been seen associated with long delays.There is no instance of a country having benefited from prolonged warfare.It is only one who is thoroughly acquainted with the evils of war that can thoroughly understand the profitable way of carrying it on.The skillful soldier does not raise a second levy, neither are his supply-wagons loaded more than twice.Bring war material with you from home, but forage on the enemy. Thus the army will have food enough for its needs.Poverty of the State exchequer causes an army to be maintained by contributions from a distance. Contributing to maintain an army at a distance causes the people to be impoverished.On the other hand, the proximity of an army causes prices to go up; and high prices cause the people's substance to be drained away.When their substance is drained away, the peasantry will be afflicted by heavy exactions.With this loss of substance and exhaustion of strength, the homes of the people will be stripped bare, and three-tenths of their income will be dissipated;While government expenses for broken chariots, worn-out horses, breast-plates and helmets, bows and arrows, spears and shields, protective mantles, draught-oxen and heavy wagons, will amount to four-tenths of its total revenue.Hence a wise general makes a point of foraging on the enemy. One cartload of the enemy's provisions is equivalent to twenty of one's own, and likewise a single picul of his provender is equivalent to twenty from one's own store.Now in order to kill the enemy, our men must be roused to anger; that there may be advantage from defeating the enemy, they must have their rewards.Therefore in chariot fighting, when ten or more chariots have been taken, those should be rewarded who took the first. Our own flags should be substituted for those of the enemy, and the chariots mingled and used in conjunction with ours. The captured soldiers should be kindly treated and kept.This is called, using the conquered foe to augment one's own strength.In war, then, let your great object be victory, not lengthy campaigns.Thus it may be known that the leader of armies is the arbiter of the people's fate, the man on whom it depends whether the nation shall be in peace or in peril.", "thread_id": 14015 }, { "@timestamp": "2023-09-14T07:13:36.63470208Z", "author": "4throck", "date": "2010-09-07T10:27:06+0100", "id": "417f85bf0c2888a0af7a160b5d4570ff", "post_id": "post-253035", "text": "River Crab said:...Wow.

Not even for those rockets that start with it as design constraint.\n\nThat eq. 1 is on page 3 in this version of the paper downloadable from the authors site.

This is a common way of writing the rocket equation for doing calculations because you can plug in different values for the payload in only one position to see how high you can make it and still reach the delta-v for orbit.The author reaches the conclusion that LH2\/LOX is theworstpropellant combination because of its low density despite its high Isp, and gives some examples that would work better:A Flexible Reusable Space Transportation System.Steven S. Pietrobon, Member, BIS.Some comment needs to be made as to why O2\/H2 has been traditionally chosen for SSTO vehicles, whereas we have come to the opposite conclusion, that O2\/H2 is the worst combination (atleast for VTHL). We believe this is due to historical reasons where it was initially recognised thatthe high exhaust speed of O2\/H2 gave significant payload increases when used in the second stage.It could have easily been thought that this advantage could flow into the first stage as has been demonstrated by the many single and two stage vehicles designed using O2\/H2.As we have shown, this is not true. For the first stage of a multistage vehicle, the propellant impulse density is the most important factor. O2\/H2 has a poor impulse density and thus makes a poor18first stage propellant. For NSTO or SSTO, high impulse density propellants are still desirable, although the highest impulse density propellants may not give the best performance.\n\np. 17The equation that shows the acceleration is increased with smaller Isp, and so smaller time required for the period where gravity drag is operating, is equation 4 on page 14.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.667104512Z", "author": "Izack", "date": "2010-05-05T05:03:07+0100", "id": "5e50d7dc9112e7a24b88852bbf245538", "post_id": "post-220665", "text": "Aries...Ares...I'm not sure which one's correct.

The Ariane 5 core stage is another weight optimized structure using common bulkhead design for its propellant tanks. The Ariane 5 core stage will also become SSTO if using high efficiency SSME's instead of the Vulcain engines.The specifications of the Ariane 5 are given here:Ariane 5 Data Sheet.http:\/\/www.spacelaunchreport.com\/ariane5.htmlThe Ariane 5 generic \"G\" version could be lofted by a single SSME. It's gross mass is listed as 170 mT, and the propellant mass as 158 mT, for a dry mass of 12 mT. The Vulcain engine is listed on this page as weighing 1,700 kg:Vulcain - Specifications.http:\/\/www.spaceandtech.com\/spacedata\/engines\/vulcain_specs.shtmlSwitching to a heavier SSME engine would add 1.4 mT to the vehicle dry mass, so to 13.4 mT for the dry mass. Using a 425s average Isp again for the SSME, this would allow a 6,000 kg payload:425*9.8ln(1 + 158\/(13.4+6)) = 9,218 m\/s.We wish to use this for a man-rated vehicle though. The Ariane 5 was originally intended to be man-rated using the Hermes spaceplane to carry crew. However, it's not certain the degree this was followed-through when the Hermes was canceled.As with the Ares I upper stage, there are means to increase the payload capacity. Subcooled densification allows 10% greater propellant to be carried, so then 10% greater mass can be lofted to orbit. This brings the total lofted weight from 19.4 mT to 21.3 mT. This extra weight can go to extra payload, so from 6 mT to about 8 mT in payload.The Ariane 5 uses an aluminum alloy, but not the aluminum-lithium alloy being used now for the lightest weight designs. Switching to aluminum-lithium allows approx. 10% weight saving over the previous aluminum alloy. The structural mass sans the SSME engine is 10.3 mT, so about 1 mT would be saved that could go to extra payload.I also mentioned before thenew research that suggests 10% to 20% can be saved in structural massbecause of overly conservative design now used. This would be another 1 mT that could be saved off the dry weight. These weight savings could go to extra payload, bringing the payload capacity to 10 mT.ESA appears to be amenable to adapting the Ariane 5 core stage for other uses, considering its agreement with ATK to use it for an upper stage. So NASA or a private company should be able to make an agreement with the ESA to use it for this purpose, based on getting sufficient financing. In this regard, to get a prototype done at low cost I suggest using the RD-0120 russian analogue of the SSME's. These are in mothballs and probably can be obtained at greatly reduced price. As a point of comparison the NK-33 was mothballed by the russians and Aerojet was able to buy 36 of them for only $1.1 million each(!) Aerojets version of the NK-33 is now on track to be used by Orbital Sciences on their Taurus II launcher.Then the Ariane 5 core version of this SSTO has the advantage over the Ares I upper stage and S-IVB versions in being already built and in current use. It also has now the capability when powered by an SSME or RD-0120 to launch a SpaceX Dragon sized spacecraft to orbit without having to use special fuel densifying or lightweighting methods.NASA has said they want to support commercial space. Support for this launcher would allow for a small, relatively low cost launcher that would permit independent private companies to launch their own manned, or cargo flights to space.\n\nHere's how you can get an all European manned SSTO using the Ariane 5 core stage and Vulcain engines this time. Note that this is one that can be produced from currently existing components, aside from the capsule, so at least an unmanned prototype vehicle can be manufactured and tested in the short term and at lowered development cost.We'll use three Vulcain 2's instead of the 1 normally used with the Ariane 5 core stage. There are varying specifications given on the Vulcain 2 depending on the source. I'll use the Astronautix site:Vulcain 2.http:\/\/www.astronautix.com\/engines\/vulcain2.htmFrom the sea level thrust given there, using three Vulcain 2's will give us one engine out capability. The weight is given as 1,800 kg. So adding on two will take the dry mass from 12 mT to 15.6 mT.To calculate the delta-V achieved I'll use the idea again to just use the vacuum Isp, but adding the loss due to back pressure onto the delta-V required for orbit, as I explained in post#136. However, here for hydrogen fuel which has higher gravity loss, I'll use a higher required delta-V of 9,400 m\/s when you add on the back pressure loss. With the vacuum Isp given for the Vulcain 2 of 434 s, we get an payload of 3.8 mT:434*9.8ln(1+158\/(15.6+3.8)) = 9,412 m\/s.Note this is just using the standard nozzle Isp for the Vulcain, no altitude compensation. So this could be tested, like, tomorrow.However, for a SSTO you definitely want to use altitude compensation. Using those engine performance programs such as ProPEP we can calculate that using long nozzles, you can get a vacuum Isp of 470 s for this engine. This means if you use altitude compensation you can get a comparable Isp. This allows us to get payload of 8 mT:470*9.8ln(1+158\/(15.6+8) = 9,400 m\/s.This will allow us to add a Dragon-sized capsule and also the reentry and landing systems to make it reusable.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.672781312Z", "author": "GLS", "date": "2008-06-11T16:17:01+0100", "id": "8879e9b24c975b8a3a9312426900459d", "post_id": "post-69089", "text": "Yes, I'll mantain it!

In addition to the gravity loss term, drag loss term, and steering loss term, there should be a fourth term for back pressure losses.Most trajectory codes, and in particular the industry-standard POST and OTIS codes, add this fourth term because it accounts for the difference between vacuum thrust and thrust at any given altitude as a delta-V loss rather than a specific impulse loss. When calculations are performed in this fashion, \"Trajectory averaged Isp\" isn't a helpful number. The difference between thrust at a given altitude and vacuum thrust is accounted for on the delta-V part of the budget rather than the Isp. It's a bookkeeping expedient - keeping all the deviations from ideal on one side of the equation.RGClark's understanding of Mitchell Burnside Clapp's argument in post 136 is incomplete. Using the vacuum Isp is industry practice, as explained above, but all that the linked post really claims is that a variety of stages have in excess of 30,000 ft\/s of delta-V, that 30,000 ft\/s is \"SSTO-class\" delta-V, and that many of them use dense propellants. Indeed, the ones using dense propellants are generally smaller than the ones using hydrogen, and while the mass ratios of such stages need to be higher for lower Isp propellants, the increase in propellant density that typically accompanies lower Isp makes that easier to achieve.Burnside Clapp does NOT argue that one should \"Just use 30,000 ft\/s.\" That's the whole point of argument linked in post 106 of this thread. Lower Isp propellants need somewhat less delta-V to orbit because of the reduction in gravity losses. It's about a 1000 ft\/sec advantage. It's nothing to do with density (except for perhaps a modest benefit in reduced drag losses), but just a \"accelerates faster earlier in the trajectory\" effect, which causes the reduction in gravity loss. But lower Isp fuels are generally also denser ones, so you can see how the two concepts get linked together.The conclusion of this line of reasoning is that while a hydrogen-based SSTO might be possible, a clear understanding of the engineering challenges of working with hydrogen and developing a vehicle that uses it might lead a designer to conclude that a dense-propellant, lower-Isp-based SSTO might be an easier engineering challenge, and have other operational advantages.Whether an SSTO is itself a good idea is an entirely separate matter. TSTO's have advantages in gross weight and payload fraction, but the upper stage has to support stage 1 burnout g fully loaded, and the lower stage has to support all that weight at burnout g as well. These conditions impose non-trivial structural penalties.

GM tells the LM when ships will be ready for transfers.The LM will have to find ways to comply with the requests from the ground and cargo managers.People can multi-task (ie they can perform multiple roles, like ground manager, then one of the guys on the ground actually doing the work.This takes care of; 1. what is the point, and 2. what we are going to do on Mars during the long launch windows.This also shows that station assembly\/dissassembly will never cease, also quite a lot of ground operations for production and what have you.---------------(dev caps)---------------Now for the grand finale: since we have a miner that can be placed anywhere and start producing cargo it is a little unrealistic and boring after a while. Especially since the ground explorers can drive in any direction and say, 'eh dig here'. So lets turn it up a bit.There are several systems we need to make;UCGO sample drill vehicle that will drive around and pickup samples and analyze them for traces of material.This will not be a function of time or something where you can be in the same place, and just keep sampling until you hit something. This will be a function oflocation. Meaning that you actually have to find deposits on the planet to drill for.When you find a deposit, and start mining for it, there will be a limited amount of resources before you have emptied that deposit. Then you have to move on.Resources will depend on your location so the ground crew will have to hunt for them.This helps us a little bit. (being it gives us more jobs and it is not dependent scenario to scenario.) This means that someones UMMU can start driving E while another drives N, at the same time. The manager has to figure roughts for the drivers to take... As long as they park in the same spot as they started, then many scenario swapping will be avoided.This sample drill vehicle and other adjustments will have to be collectively integrated together, without the ability for users to just open a config file and 'find' resource deposits (makes it fun this way).We will also need the UCGO cargo textures and possibly meshes made for the various types of materials found on the periodic table.Big project but I think its doable and will be fun too. :thumbup:Thoughts?", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:36.01012224Z", "author": "Izack", "date": "2012-11-21T16:27:56+0000", "id": "23c3bda578c9078eb6a0e339ef9253c0", "post_id": "post-252013", "text": "Keatah said:Pffaggh..

Congress wants this reinstituted quickly but NASA says they can't do it with the money being provided by Congress.In regards to this proposal it is notable McDonnell Douglas, now a subsidiary of Boeing, was also the contractor on the DC-X, legendary for its low development cost, quick turnaround time, and small ground crew.In this report Boeing proposes heavy lift launchers using existing components:Heavy Lift Launch Vehicles with Existing Propulsion Systems.Benjamin Donahue, Lee Brady, Mike Farkas, Shelley LeRoy, Neal GrahamBoeing Phantom Works,Huntsville, AL 35824Doug BlueBoeing Space Exploration,Huntington Beach, CA 92605http:\/\/www.launchcomplexmodels.com\/D...0-2370-650.pdfOne of the proposals is of a manned launcher with the Orion capsule using a shuttle ET propellant tank and four RS-68 engines. This does not use an upper stage but is not a single-stage-to-orbit vehicle because the final push to orbit is made by the onboard thrusters on the Orion spacecraft.However, it is interesting in this report comparison is made to theS-IVBupper stage on the Apollo rocket. I was reminded of a suggestion of Gary Hudson that the S-IVB would be single-stage-to-orbit with significant payload if it used the high efficiency SSME rather than the J-2 engine:A Single-Stage-to-Orbit Thought Experiment.Gary C Hudsonhttp:\/\/www.spacefuture.com\/archive\/a...periment.shtmlIn Hudson's proposal the vehicle could lift 10,360 lbs, 4,710 kg. This would be just enough to carry the crewed version of theDragon spacecraftwithout cargo.\n\nThe point of the matter is that if you use highly weight optimized structures and high efficiency engines at the same time then what you wind up with will be a SSTO capable stage. The Ariane 5 core stage is another weight optimized structure using common bulkhead design for its propellant tanks. The Ariane 5 core stage will also become SSTO if using high efficiency SSME's instead of the Vulcain engines.The specifications of the Ariane 5 are given here:Ariane 5 Data Sheet.http:\/\/www.spacelaunchreport.com\/ariane5.htmlThe Ariane 5 generic \"G\" version could be lofted by a single SSME. It's gross mass is listed as 170 mT, and the propellant mass as 158 mT, for a dry mass of 12 mT. The Vulcain engine is listed on this page as weighing 1,700 kg:Vulcain - Specifications.http:\/\/www.spaceandtech.com\/spacedata\/engines\/vulcain_specs.shtmlSwitching to a heavier SSME engine would add 1.4 mT to the vehicle dry mass, so to 13.4 mT for the dry mass. Using a 425s average Isp again for the SSME, this would allow a 6,000 kg payload:425*9.8ln(1 + 158\/(13.4+6)) = 9,218 m\/s.We wish to use this for a man-rated vehicle though. The Ariane 5 was originally intended to be man-rated using the Hermes spaceplane to carry crew. However, it's not certain the degree this was followed-through when the Hermes was canceled.As with the Ares I upper stage, there are means to increase the payload capacity. Subcooled densification allows 10% greater propellant to be carried, so then 10% greater mass can be lofted to orbit. This brings the total lofted weight from 19.4 mT to 21.3 mT. This extra weight can go to extra payload, so from 6 mT to about 8 mT in payload.The Ariane 5 uses an aluminum alloy, but not the aluminum-lithium alloy being used now for the lightest weight designs. Switching to aluminum-lithium allows approx. 10% weight saving over the previous aluminum alloy. The structural mass sans the SSME engine is 10.3 mT, so about 1 mT would be saved that could go to extra payload.I also mentioned before thenew research that suggests 10% to 20% can be saved in structural massbecause of overly conservative design now used. This would be another 1 mT that could be saved off the dry weight. These weight savings could go to extra payload, bringing the payload capacity to 10 mT.ESA appears to be amenable to adapting the Ariane 5 core stage for other uses, considering its agreement with ATK to use it for an upper stage. So NASA or a private company should be able to make an agreement with the ESA to use it for this purpose, based on getting sufficient financing. In this regard, to get a prototype done at low cost I suggest using the RD-0120 russian analogue of the SSME's. These are in mothballs and probably can be obtained at greatly reduced price. As a point of comparison the NK-33 was mothballed by the russians and Aerojet was able to buy 36 of them for only $1.1 million each(!) Aerojets version of the NK-33 is now on track to be used by Orbital Sciences on their Taurus II launcher.Then the Ariane 5 core version of this SSTO has the advantage over the Ares I upper stage and S-IVB versions in being already built and in current use. It also has now the capability when powered by an SSME or RD-0120 to launch a SpaceX Dragon sized spacecraft to orbit without having to use special fuel densifying or lightweighting methods.NASA has said they want to support commercial space.

It's 3 steps away from Star Wars.I was originally inclined to support the Arrow, but after giving some hard thought to the matter I believe an interplanetary stack with equipment to build the MSS is the way to go, at least for the first phase of the operation. Perhaps once it has built the station, the Arrow can be launched.I really have to support the James Cook for this job. It can carry two landers, as well as the station building supplies and tugs to build it without being too enormous (like the Deepstar or Descartes.)I'd say two journeys to establish a foothold: one for the MSS and two initial landings (At Juventae Chasma and Olympus Mons, perhaps?), and one to bring two heavy landers and parts for a permanent base.The second voyage could be where the Arrow comes in (it's a base in its own right and can land on the surface by itself, no landers needed.)For the initial historic landings, we'd obviously use XR-2s or DG-IVs (Not quite unrealistic if we use realistic settings.) Since both of these craft can take off themselves, after a few days on the surface they can head back up for rendezvous at the MSS and await the arrival of Expedition Two in whatever form it takes. If the Arrow is used for the second, then we have a spaceworthy vessel already at Mars doing nothing, so why not send it to Phobos while we wait? It can also act as the emergency return vehicle in case of, well, and emergency.Now that I've said that, the Arrow looks like the ideal way to go for the second voyage.

Both size and mass -wise. Not sure what our lifting capacity from Mar to orbit will be.\n\nUsing the ET as a rough estimation of LOX\/LH2 mass\/volume ratio, it has 358.69kg of propellant per cubic meter.Alright, this is what I'm envisioning; containers likethis(for ground fuel containers) would be good as semi-permanent structures. While the miner can produce smaller drums that can be used for packing fuel to orbit.Now I am starting to think that for the 'smaller drums' we can actually use the fuel cargo supplied with UCGO. Since like ~9 of them will fill up the fuel tanks of DGIV, they should be enough. Anyway, if we had to haul them, we would have to make them fit in cargo bays and well, more hassle then I think its worth and redesigning the wheel I think.Summary: the miner should produce UCGO fuel cargo for simplicity sake.The larger drums (since I am assuming, alteration of Arrows hover engines to permit landing) should fill up 800,750kg of fuel with say, 5 drums.Assuming 1.25:1 ratio for width\/high large drum size and 160,150 kg for drum,(don't mind my scribbles)[MATH]\\pi hr^2 = [\/MATH](volume of container)[MATH]2r=1.25(h)[\/MATH][MATH]\\pi h(0.625h)^2 = .39\\pi h^3[\/MATH][MATH]~.39\\pi h^3 = ~446.49[\/MATH] ( = (1\/5)\/358.69 of 800,750kg)So the large drum should be;h = ~7.14r = ~4.46Now then, I think either we can do 2 things, be realistic and set the miner (or other vessel) to have fuel containers fill as a function of time, or we can just have the oil drums set to act as UCGO fuel stations.Urwumpe said:The mars spacecraft should be modular, but should not require at the same time excessive LEO assembly phases. More than 4 modules per mars transfer would be painful.Dilemma:I would like the technology to be closer to todays reality, but I can see that this would also prevent many less than advanced players from taking part. So, I would suggest that a DG-Tech Mars vehicle would be better. A NERVA looks good, but is maybe already too hard for some.\n\nThis would assume that we are developing a new realistic multistage Apollo like vessel capable of Mars landings and returns. I am all for it, but I think it would take more time then most is willing to wait... unless I am wrong. :shrug:Urwumpe said:A program patch would be nice, but is currently the most useless thing in the queue. We need to get things started so the program is running, and then, when all the dangerous decisions are behind us, we can talk again about the decorations.\n\n:hesaid:Urwumpe said:Before we decide on which vehicle we use, we should know what the vehicle(s) will transport. Thus, I think the task for the weekend should be: \"Plan how the first Mars expedition should look like, how many consumables they need to survive there, and how it can get transported\". This includes making suggestions how the mars base will look like in the first 18 months or how it evolves in that time.Remember: There will be a few weeks of an open launch window on Mars, that permits us to transport material there and let spacecraft directly fly back to Earth before the return window closes for 18 months. After it closes, the permanent expedition crew that is left on Mars will have to survive on what is on Mars, no resupplies possible. And I am sure, we want to call such a thing a base and not a tent city for some days before all go away for months.I am also sure, we don't want to fast forward until the Earth-Mars window opens again. So, we need so meaningful missions on Earth and Mars that fill the gap.\n\nI thought we kind-of already got an idea of whats coming along?post141Its just a matter of writing up something that the UMMU have to be doing during the stay there.About mission windows, while I get they are limiting, what if we dont really go for the 'most fuel efficient manner.' If the stack or any other ship has enough Delta V supply to get to a planet at the most direct, fastest and least efficient possible methods, why not cut out the months of wait and launch imminently? -so long as you have it in the delta V budget of course.Urwumpe said:We also need to decide first, how the crew gets to Mars and how they leave it: On the same vehicle as they used for landing (Apollo like) or use a Earth Return Vehicle (Like Mars Direct)? Swap spacecraft or not? Mars Orbit Rendezvous?\n\nAFAIK, so far we have 2 vessels, the stack which is doubling as the station and the Arrow(with smaller craft included)Just checking around OH, we really don't have any 'realistic' vehicle capable of a Mars journey.

Yet, right now, the mini-Cooper-sized rover is playing the role of stunt double for NASA astronauts.\"Curiosity is riding to Mars in the belly of a spacecraft, where an astronaut would be,\" explains Don Hassler of the Southwest Research Institute in Boulder, Colorado. \"This means the rover experiences deep-space radiation storms in the same way that a real astronaut would.\"Indeed, on Jan. 27th, 2012, Curiosity's spacecraft was hit by the most intense solar radiation storm since 2005. The event began when sunspot AR1402 produced an X2-class solar flare. (On the \"Richter Scale of Solar Flares,\" X-flares are the most powerful kind.) The explosion accelerated a fusillade of protons and electrons to nearly light speed; these subatomic bullets were guided by the sun's magnetic field almost directly toward Curiosity.When the particles hit the outer walls of the spacecraft, they shattered other atoms and molecules in their path, producing a secondary spray of radiation that Curiosity both absorbed and measured.\"Curiosity was in no danger,\" says Hassler. \"In fact, we intended all along for the rover to experience these storms en route to Mars.\"Unlike previous Mars rovers, Curiosity is equipped with a Radiation Assessment Detector. The instrument, nicknamed \"RAD,\" counts cosmic rays, neutrons, protons and other particles over a wide range of biologically-interesting energies. RAD's prime mission is to investigate the radiation environment on the surface of Mars, but researchers have turned it on early so that it can also probe the radiation environment on the way to Mars as well.Curiosity's location inside the spacecraft is key to the experiment.\"We have a pretty good idea what the radiation environment is like outside,\" says Hassler, who is the principal investigator for RAD. \"Inside the spacecraft, however, is still a mystery.\"Even supercomputers have trouble calculating exactly what happens when high-energy cosmic rays and solar energetic particles hit the walls of a spacecraft. One particle hits another; fragments fly; the fragments themselves crash into other molecules.\"It's very complicated. Curiosity is giving us a chance to actually measure what happens.\"Even when the sun is quiet, Curiosity is bombarded by a slow drizzle of cosmic rays\u2014high-energy particles accelerated by distant black holes and supernova explosions.

Strickland, Jr.September, 2011\"What amazes people is that SpaceX has broken the long-sought 1,000dollars a pound to orbit price barrier with a rocket which is stillexpendable. 'How can he (SpaceX CEO Elon Musk) possibly do this?' theyask. The Chinese have said flatly that there is no way they cancompete with such a low price. It is important to remember that thiswas not done in a single step. The Falcon 9 already has a large priceadvantage over other boosters, even though it does not have thepayload capacity of some of the largest ones. The 'Heavy' will eventhis score and then some. At last count, SpaceX had a launch manifestof over 40 payloads, far exceeding any current government contracts,with more being added every month. These are divided between theFalcon 9 and the Falcon Heavy.\"http:\/\/www.nss.org\/articles\/falconheavy.htmlI think the most important accomplishment of SpaceX might turn out to be that they showed in stark terms that privately financed spacecraft, both launchers and crew capsules, can be accomplished at 1\/10th thedevelopmental cost of government financed ones. Imagine a manned, reusable orbital launcher, for example, instead of costing, say, $3 billion, only costing $300 million to develop.As I argue, the key variable that made this reduction possible is that the launcher was privately financed. That is, it was the launch company's own money that was financing its development. In that case it makes sense the company would be more fiscally responsible in developing it.Then the first step in reducing the price to orbit is making the vehicles be privately financed. But if the launch companies are going to spend their own money, they have to be convinced they can make a profit on them. This will come if there is a significant market.My view is that there would be a significant market for small, privately owned, SSTO's. When you consider that with orbital refueling such craft can also make lunar missions, the market becomes even more apparent....\n\nSpace vehicle launches could be routine if they could take off horizontally from airliner runways as a single stage, like aircraft. It was thought that wings would just be dead weight on ascent but in fact following a lifting trajectory can cut in the range of 40% off the propellant requirements from a SSTO if it is at high lift\/drag ratio. So wings can \"carry their own weight\", so to speak even on ascent.Here's a heuristic argument that an SSTO making a lifting trajectory at high L\/D ratio can save on propellant requirements. I'll regard the straight-line path as my X-axis and the perpendicular to this as the Y-axis. Note this means my axes look like they are at an angle to the usual horizontal and vertical axes, but it makes the calculation easier. Call the thrust T, and the mass, M. Then the force component along the straight-line path, our X-axis, is Fx = T - gMsin(\u03b8) - D and the forcecomponent along the Y-axis is Fy = L - gMcos(\u03b8).We'll set L = gMcos(\u03b8), since the vehicle is traveling along the straight-line, our X-axis, so the force component in the Y-direction is zero. Then the force along the straight-line is Fx = T -gMsin(\u03b8) - gMcos(\u03b8)\/(L\/D). As with the calculation for the usual rocket equation, divide this by M to get the acceleration along this line, and integrate to get the velocity. The result is V(t) = Ve*ln(M0\/Mf) - g*tsin(\u03b8) - g*tcos(\u03b8)\/(L\/D), with M0 the initial mass, and Mf, the mass at time t, a la the rocket equation. If you make the angle \u03b8 (theta) be shallow, the g*tsin(\u03b8) term will be smaller than the usual gravity drag loss of g*t and the (L\/D) divisor will make the cosine term smaller as well.Now note that the equation includes *both* the gravity and air drag. Secondly, note that though using aerodynamic lift generates additional, large, induced drag, this is covered by the fact that the L\/D ratio includes this induced drag, since it involves the *total* drag.Some preliminary calculations I did suggest you could save in the range of 40% off your propellant requirements by reducing the gravity loss in this fashion if indeed your L\/D ratio is 7+, at the speed range up to the high supersonic to low hypersonic.A reduction in the propellant requirements this high means you could carry significant payload to orbit even with standard wing weight, estimated as 10% of the vehicle weight, which would be the gross takeoff weight for a horizontally launched vehicle.However, we can cut this weight even further. First, even for standard wings you could cut this wing weight by half with modern materials. But a key fact is that you don't even need wings for a horizontal liftoff. Lifting bodies can perform horizontal takeoffs without additional wings. Lifting bodies have long been investigated for use as reentry vehicles, but it seems to have been overlooked to use them also for horizontal takeoff.The problem though would be to get mass efficient propellant tanks for the vehicle. The propellant tanks are frequently the heaviest component of the dry weight of the vehicle, even more than the engines.But the lifting body would have non-cylindrical shape. What killed the X-33\/VentureStar program was the inability to get light-weight tanks for the X-33's conformally shaped tanks. Even using composite materials the non-circular cross sections would have resulted in tanks twice as heavy as aluminum tanks of usual cylindrical shape [1].It turns out the determining factor for the heavy weight of rocket propellant tanks is they have to be pressurized. This is because of the requirements for proper operation of the turbopumps on rocket engines [2]. Pressurized tanks have to have a certain thickness to safely hold the contents.However, quite key is the fact that this is a requirement of turbopumps but not other types of pumps [3]. XCOR because it's using wing tanks for its Lynx suborbital vehicle plans to use reciprocating (piston) pumps [4]. These require reduced pressurization in the tanks, if any. And the tanks in the wings on aircraft commonly are also not pressurized. XCOR had to develop these since they intend to carry the propellant in wing tanks which being non-circular would have been very heavy if they had to be pressurized.Another possibility would be to use inflatable wings. These can also save weight over standard wings [5].Bob Clark1.)Space Access Update #91 2\/7\/00.The Last Five Years: NASA Gets Handed The Ball, And Drops It.\"...part of L-M X-33's weight growth was the \"multi-lobed\" propellant tanks growing considerably heavier than promised.Neither Rockwell nor McDonnell-Douglas bid these; both used provencircular-section tanks. X-33's graphite-epoxy \"multi-lobed\" liquidhydrogen tanks have ended up over twice as heavy relative to theweight of propellant carried as the Shuttle's 70's vintage aluminumcircular-section tanks - yet an X-33 tank still split open in testlast fall. Going over to aluminum will make the problem worse; X-33's aluminum multi-lobed liquid oxygen tank is nearly four times asheavy relative to the weight of propellant carried as Shuttle'saluminum circular-section equivalent.\"http:\/\/www.space-access.org\/updates\/sau91.html2.)Fuel tank scaling laws (Henry Spencer).http:\/\/yarchive.net\/space\/launchers\/fuel_tank_scaling_laws.html3.)[ame=\"http:\/\/en.wikipedia.org\/wiki\/NPSH\"]NPSH - Wikipedia, the free encyclopedia[\/ame]4.)XCOR Aerospace and United Launch Alliance.Announce Successful Hydrogen Piston Pump Tests.http:\/\/www.xcor.com\/press-releases\/...nounce_successful_hydrogen_pumping_tests.html5.)An inflatable wing using the principle of Tensairity.http:\/\/www.empa.ch\/plugin\/template\/empa\/*\/107170", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.005735168Z", "author": "N_Molson", "date": "2012-10-10T12:25:50+0100", "id": "50cd8fd09639ea420b9cdb4dd0cf92a5", "post_id": "post-251961", "text": "As the Sun set on sol 49 (September 25, 2012), Curiosity used its Navigation Camera to take a panoramic view of the dramatically lit landscape.\n\nSo beautiful... :blink:", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:04.738582784Z", "author": "Arrowstar", "date": "2010-04-26T17:36:41+0100", "id": "725a2ebdc0841e6eb10bb2422687f063", "post_id": "post-219299", "text": "Salun said:must......resist.....can't.....Mustn't.......RESISTANCE IS FUTILE!http:\/\/www.southparkstudios.com\/clips\/155142\/?searchterm=Free+Willzyx\n\nGah, beaten to the punch!:)", "thread_id": 14012 }, { "@timestamp": "2023-09-14T07:13:05.646063872Z", "author": "fireballs619", "date": "2010-06-08T17:20:10+0100", "id": "5a1fc5e905aa1534bf4b6ee45d165db5", "post_id": "post-220997", "text": "I personally think we should switch to Orbiter 2010, because of cleaner HUDs, not to mention graphics.

In fact the payload will be so high you can add reentry and landing systems and still carry significant payload.

With the xr-2's (or DG's for that matter) docked in that manner I'm afraid that once the stack is under thrust it would stress the docking collar to the point of failure. While I don't think that that particular effect is modeled in orbiter, I still think that they should be docked parallel to the stack instead of perpendicular to it.\n\nThat should be fairly easy to fix. At first I had them docked to the port and starboard hab modules instead of the core block, but they were misaligned and overlapped the stack. It's probably just a matter of rotating the two habs 90 degrees so the Ravens' will be parallel with the stack. I'll get right on it. Would you prefer them pointing toward the front or the back?", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:05.661176832Z", "author": "Bj", "date": "2010-05-04T03:32:22+0100", "id": "9acc0c1c048b0fc4b33fb4bbdd16a30a", "post_id": "post-220612", "text": "Alright alterations colored;Vessels;Cargo vessel - ArrowMSS station platform (engines to push MSS to Mars) - James CookMini landers - (XR2||DGIV)Ares launchersSome fabricated (ISS like) vessel that will be transport\/crew type ship (MSS)Other LaunchersGoal of Project;Establish colony forScience ExperimentsMiningGeneral mission line;Start construction of Mars space station (MSS)Develop modules so that Arrow can dock with station.

This is a fallacy. Only because most rockets with high propellant density also have a short burn time (solids!), this can backfire for SSTOs...\n\nI agree this is counter intuitive. And the reason behind it is even more counter intuitive: it's because the gravity loss isreducedby using a lower Isp propellant. Since dense fuels have a lower Isp than hydrogen, their gravity loss will be reduced.Here's one explanation of this effect:Hydrogen delta-V (Henry Spencer; Mitchell Burnside Clapp).http:\/\/yarchive.net\/space\/rocket\/fuels\/hydrogen_deltav.htmlHere's a simplified case that makes it believable. The gravity loss occurs when the vehicle is traveling vertically to achieve the necessary altitude for orbit. This is done with orbital rockets by getting to some particular vertical velocity component so that the rocket's momentum will allow it to coast in the vertical direction to reach that altitude. The rest of the trip after the vertical portion is used to make the horizontal thrust needed to get to the necessary tangential velocity for orbit.So in this simplified case I'll just look at the case where your rocket only needs to get to the needed vertical speed for the altitude for orbit, say 1,400 m\/s, not to achieve orbital velocity. Suppose now you have two vehicles one hydrogen-fueled the other kerosene or other dense propellant fueled. Let them both have the same liftoff thrust\/weight ratio, say, 1.4. Note that because the dense propellant has a lower Isp its mass ratio will be higher than the hydrogen to get to the same velocity, so it will have a higher propellant load.Then near the end of the trip when most of the propellant is burned off, note that the dense propellant vehicle will have a higher thrust\/weight ratio than the hydrogen one because its thrust needed to be several times higher compared to its dry mass because of the higher initial propellant load. This turns out to be the case through out the trip after the initial liftoff: the acceleration will be greater for the dense propellant vehicle. Therefore its gravity loss will be reduced because the time of the vertical trip is reduced.Here's another way of seeing the needed burn time will be smaller for the dense propellant case. Recall that the thrust of a rocket is (thrust) = (propellant flow rate)x(exhaust velocity). We know there will be a greater amount of propellant for the dense case compared to the hydrogen case. So the thrust will have to be proportionally larger as well, and so the propellant flow rate will also need to be greater.Now since the flow rate for the dense propellant will also be higher does that mean they will both burn up all their fuel in the same length of time? The key point is they won't. The dense propellant vehicle will burn up all its fuel in a shorter period of time (we're still looking at the simplified case of only looking at a vertical trip to 1,400 m\/s.)The reason for this is because of that exhaust velocity term in the equation for thrust. If the propellant load is some multiple times that of the hydrogen case the thrust will have to be similarly multiply times higher. But the increased propellant flow rate that gives that multiple times greater thrust will have to behigherthan the multiple of the amount of greater propellantbecause that exhaust velocity term is smaller. For instance if the dense fuel thrust has to be, say, twice that of the hydrogen case, then the propellant flow rate will have to bemore than twice as greatto make up for the lower exhaust velocity term.This means the length of time for the dense case to burn up its fuel will be shorter, resulting in a reduced gravity loss. The actual scenario for an orbital flight where there is also a horizontal thrust portion is only slightly more complicated but it also leads to the conclusion the gravity drag is reduced for the dense propellant case.If you want to see an equation that expresses the idea the acceleration is greater for the dense propellant case, even with the same initial T\/W ratio, see equation 4 on page 14 here:A flexible reusable space transportation system.by Dr. Steven PietrobonJournal of the British Interplanetary Society.vol. 53, pp. 276-288, May\/June 2000http:\/\/www.sworld.com.au\/steven\/pub\/nsto.pdfBob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:36.139149312Z", "author": "Orbinaut Pete", "date": "2010-08-31T17:04:51+0100", "id": "732664179436bab357d17ae7e97d551a", "post_id": "post-252283", "text": "NASA TV Video: \"Shuttle Astronaut Bill Lenoir Dies\".\u200b", "thread_id": 16277 }, { "@timestamp": "2023-09-14T07:13:05.652445184Z", "author": "Urwumpe", "date": "2010-06-12T14:06:15+0100", "id": "329e47ecc9c0439c69c679130a496a03", "post_id": "post-221053", "text": "Ashaman42 said:As for engines I've been pottering at a cargo lander\/lifter and am leaning towards a methane\/Lox engine.

I really wish I am taking physics now,:)Alright, I was going to ask about if we really needed artificial gravity, but now looking at the consequences of not having artificial gravity, I changed my mind:)The article says;Indeed, the physiologic responses to continuous exposure to anything other than 1 G are unknown.\n\nI wish they never canceled the CAM...The article goes on to 'Continuous Artificial Gravity Questions.' Maybe this could be a goal of our 'scientific research' on Mars;)...So just making sure I understand Coriolis right, if the astronaut stands\/shifts\/moves, it alters the feeling of gravity or force dependent on distances from the center, direction of the movement and velocity of the movement.This is obviously undesirable since the feeling of gravity will change because of the small(er) distances we have to work with, and will cause space sickness.Urwumpe said:For the MSS - The maximum long-term spin-rate for producing artificial gravity without critical Coriolis force is 6 rpm, and since I assumed in the hab design that it gets such artificial gravity during Mars-Earth transfer (only short phases of micro-gravity), this means the minimum distance from rotation axis to Hab bottom is 12.6 meters. If we use a longer radius, the differences in artificial gravity become less, and we can use even smaller rotation rates.Thus a long boom like structure would be optimal in the MSS design. If we want only 10% variance in artificial gravity between top and bottom of the hab, the length would have to be 126 meters...it scales linear.\n\nI am assuming your meaning a station design like on page 14, and I take it you don't think a simple small module where the astronaut can lay in, (say when sleeping for 8 hours a day) so the astronaut will not move and more or less sit in a mummy bag and be mostly immobilized will be suitable for long duration trips, let alone Mars journeys.The only problems I can foresee, is;1.

The Air Force favors this since this may also be used to tow inactive satellites out the way of operable satellites, thus reducing the problem of space debris:Article:World's First Space Gas Station for Satellites to Launch in 2015.by Clara Moskowitz, SPACE.com Senior WriterDate: 15 March 2011 Time: 06:03 PM ET\"Until now, satellites orbiting around Earth have been limited by how much fuel they carry onboard. Once those tanks run dry, the satellites die, sometimes languishing in space as uncontrollable debris that then poses the risk of colliding with other spacecraft.\"The new plan offers the potential not just to extend the lives of working satellites, but to help combat the growing space junk problem. The satellite, called the Space Infrastructure Servicing (SIS) vehicle, is designed not just to transfer more fuel into existing satellites, but to inspect, tow, reposition and make minor repairs to them.\"In addition to its tank of fuel, the refueling satellite will carry a robotic arm that can be used to grab onto satellites and tug at stuck solar array panels, for example, or attempt other minor fixes to broken parts.'This is a first-time-ever, huge, huge, huge event,' said Andrew Palowitch, director of the Space Protection Program, a joint project of U.S. Air Force Space Command and the National Reconnaissance Office, speaking at a National Research Council workshop on orbital debrislast week.\"Palowitch stressed that the ability to tow or refuel dead satellites in order to steer them out of the way would have a big impact on the growing problem of dangerous space debris clogging the crowded corridors of Earth orbit. [Worst Space Debris Events of All Time]'In the context of debris removal, this is the absolute best and absolute most fantastic new venture for the entire space community,' he said.\"The refueling satellite will be able to move dead spacecraft to what's called the 'graveyard orbit,' where they are high enough that they should not pose a risk to working satellites, or maneuver them low enough that they break apart in Earth's atmosphere.\"http:\/\/www.space.com\/11135-satellite-refueling-mission-space-debris.htmlThen the Air Force recognizes the usefulness of reusable vehicles, when they are in-space. However, the importance of reusable SSTO's is that they could also return these satellites to Earth for repair or salvage.Remember the old science fiction series Salvage 1:Salvage 1.Salvage 1 - Wikipedia, the free encyclopediaThe theme of the show was a small \"home made\" spaceship was used to return space junk to Earth. I used to think the show was quite implausible because the spaceship went all the way to the Moon and everybody \"knows\" it takes huge Saturn V sized rockets to do that.However, as I discussed in post#136small, low cost SSTO's are indeed possible. And it is a known fact that if you have refueling in LEO then an SSTO can go all the way to the Moon, land, take off, and return to Earth on that one single refueling. So in fact the idea of salvaging spacecraft or satellites from the Moon and\/or from GEO is feasible with SSTO's and on-orbit propellant depots.Then this provides another financial benefit for SSTO's for private developers and for the Air Force. Imagine being able to retrieve satellites, the largest of which can cost upwards of a billion dollars, for reuse or possibly for sale. This does though raise the question of what would be the salvage laws for space.\n\nHere's a link to the full pilot movie:A single stage vehicle that can travel to the Moon and back is possible now with standard chemical propulsion if you have orbital refueling:The Coming SSTO's.http:\/\/exoscientist.blogspot.com\/2012\/05\/coming-sstos.htmlBob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.611965696Z", "author": "Izack", "date": "2010-05-06T18:27:49+0100", "id": "8e31db0c04e7940df4110b92cd69109b", "post_id": "post-220713", "text": "Bloodworth said:While I agree with everything you've just said, part of simulating the tasks is the actual flights.

However,I was surprised to find after doing the calculation you don't even needthe high efficiency engines to get the SSTO. The low efficiency SpaceXMerlin engines would be sufficient for example, IF you have altitude compensation.The impetus for trying the calculation was from a report by SpaceXthat you could get the same performance from a planned heavy liftfirst stage using a lower performance Merlin 2 engine compared to thehigh performance RS-84 engine. The reason was the lower Isp of theMerlin was made up for by its lower weight:SpaceX Propulsion.http:\/\/images.spaceref.com\/news\/2010\/SpaceX_Propulsion.pdfNow note that the biggest single contributor to the vacuum Isp of anengine is not the chamber pressure, but the nozzle length. Forexample, the Merlin Vacuum raises its vacuum Isp to 342 s from the 304s Isp of the Merlin 1C by having a longer nozzle, even though thechamber pressure remains the same, ca. 100 bar.So I'll redo the calculation for the SSTO using the SpaceX Falcon 1first stage but using Merlin engines this time. We'll assume thatusing altitude compensation we are able to get an engine with the samevacuum Isp as the Merlin Vacuum but able to launch from ground.We'll use the soon to be introduced Merlin 1D:SpaceX Plans To Be Top World Rocket Maker.Aug 11, 2011By Guy NorrisSan Diegohttp:\/\/www.aviationweek.com\/aw\/generic\/story.jsp?id=news\/awst\/2011\/08\/08\/AW_08_08_2011_p27-354586.xml&headline=SpaceX%20Plans%20To%20Be%20Top%20World%20Rocket%20Maker&channel=defenseUsing the 160 to 1 thrust\/weight ratio and 155,000 lbs. vacuum thrustgiven, it has a mass of 970 lbs., 440 kg. However, this would make itoverpowered for the Falcon 1 first stage only. So we'll use two copiesof this stage powered by a single Merlin 1D.The original Falcon 1 first stage with the Merlin 1C engine has a dry massof 1,360 kg. I estimated the mass of the Merlin 1C in the prior post tobe 650 kg. So without the engine, the stage weighs 710 kg. So two ofthem will be 1,420 kg without engines, and adding on the Merlin 1Dengine gives this a mass of 1,860 kg.The propellant mass of the two copies of the first stage is 43,080kg. Then to calculate the payload that can be carried I'll again justuse the vacuum Isp and take the required delta-V as 9,150 m\/s. Weconclude a payload of 1,140 kg can be lofted:342*9.8ln(1 + 43,080\/(1,860 + 1,140)) = 9,160.Now we'll estimate how much the payload can be if we use a higherenergy density fuel such as methylacetylene and use lightweightcomposites for the stage. I'll get a rough idea how high the Isp canbe for this case by assuming it is increased proportionally to thesame degree as for the high efficiency engine case. That is, usingmethylacetylene in the high efficiency case resulted in increasing thevacuum Isp to 384 s from the 360 s vacuum Isp for the kerosene.Assuming the vacuum Isp will be increased to the same proportion heregives us a vacuum Isp of 365 s for methylacetylene and the Merlin 1Dengine.For the reduced stage weight using composites, assume again it willbe reduced by 40% aside from the engines. Then the stage weight withthe Merlin 1D engine will be .6*1,420 + 440 kg = 1,290 kg. Then willbe able to loft a payload of 2,320 kg:365*9.8ln(1 + 43,080\/(1,290 + 2,320)) = 9,160 m\/s.Also, quite likely SpaceX could make a half-size version of theMerlin 1D engine. So you could use a single copy of the Falcon 1 firststage. Then the payload would be approximately cut in half, 570 kg forthe kerosene\/standard stage version and 1,160 kg for themethylacetylene\/composite stage version.Note that low chamber pressure, low performance engines can also beused to power the SSTO's is extremely important. Such engines haveless complicated combustion cycles and have to withstand much lessstrenuous operating regimes. This makes them cheaper, simpler, easierto maintain, and easier to make reusable. So the most costly componentof any rocket, the engines, become markedly cheaper for the proposedSSTO.What is key though is to come up with ways to get the needed altitudecompensation without adding on too much to the engine weight. In afollowing post I'll discuss some methods this might be accomplished.Bob Clark", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.147453952Z", "author": "RisingFury", "date": "2010-04-28T13:14:19+0100", "id": "328bbb56c8616b40179057d59b2a25a1", "post_id": "post-219658", "text": "This telescope is actually a downsized version of the OLT - Overwhelmingly Large Telescope.

What about all the launchers?if you look at Ares V - 160,000kg to LEO, or 71,100-60,000kg to TLI. Much less weigh carried per launch meaning more Ares launches, meaning more (virtual) money (each engine, vehicle construction, ext).... a lot of dead weight and fuel to break into LEO. Better, I think to launch to LEO, then with a reusable engine push all the joined modules to Mars.Salun said:2. Moon Base Control(MBC)\n\nSo is anything wrong with Huston?

Such a vehicle might have comparable liftoff thrust to F9, along with higher ISP in a vacuum, and fewer engines (lower cost, less risk of catastrophic engine failure).", "thread_id": 14079 }, { "@timestamp": "2023-09-14T07:13:05.624738048Z", "author": "Bj", "date": "2010-05-12T01:58:04+0100", "id": "8958492c4f3e66a2c91d5e1256174a2b", "post_id": "post-220823", "text": "Continued discussion from community section:Pablo49 said:Ive seen it like that, and seen it as a stack that drops its MSS modules and picks up cargo and returns its engines back to earth.

It was accompanied by the rocket-powered descent stage that will fly the rover during the final moments before landing on Mars. The C-17 flight began at March Air Reserve Base in Riverside, Calif., where the boxed hardware had been trucked from NASA's Jet Propulsion Laboratory in Pasadena, Calif.Click on image for details\u200bCuriosity, the Mars Science Laboratory mission's rover, along with the mission's descent stage, arrived at NASA's Kennedy Space Center, Fla., on June 22, 2011, aboard a U.S. Air Force C-17 transport plane.\u200bImage credit: NASA\u200bThe rover's aeroshell -- the protective covering for the trip to the Red Planet -- and the cruise stage, which will guide it to Mars, arrived at Kennedy last month. The mission is targeted to launch from Cape Canaveral Air Force Station between Nov. 25 and Dec. 18. The car-size rover will land on Mars in August 2012.\"The design and building part of the mission is nearly behind us now,\" said JPL's David Gruel, who has managed Mars Science Laboratory assembly, test and launch operations since 2007. \"We're getting to final checkouts before sending the rover on its way to Mars.\"The rover and other spacecraft components will undergo more testing before mission staff stack them and fuel the onboard propulsion systems. Curiosity should be enclosed in its aeroshell for the final time in September and delivered to Kennedy's Launch Complex 41 in early November for integration with a United Launch Alliance Atlas V rocket.Curiosity is about twice as long and more than five times as heavy as any previous Mars rover. Its 10 science instruments include two for ingesting and analyzing samples of powdered rock delivered by the rover's robotic arm. During a prime mission lasting one Martian year -- nearly two Earth years -- researchers will use the rover's tools to study whether the landing region has had environmental conditions favorable for supporting microbial life and favorable for preserving clues about whether life existed.{...}NASA Press Release:RELEASE : 11-201 - NASA Mars Rover Arrives In Florida After Cross-Country Flight", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.657645824Z", "author": "Artlav", "date": "2010-05-02T21:42:03+0100", "id": "724daa9076034a5796035b66b5bc57a4", "post_id": "post-220572", "text": "Sounds like a great idea in general, but what i would have hoped to see from it is a nice, station-like modular, near-future tech interplanetary spaceship stack, a thing which is notoriously lacking in Orbiter for the moment.Thus, instead of Arrow, to build a Mars-bound vessel in MEO, using existing add-ons and maybe some glue meshes, and then launch it Mars-way.", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:05.088792832Z", "author": "Artlav", "date": "2013-05-14T15:13:39+0100", "id": "e5c3b05adda56f9259360206d2223199", "post_id": "post-219579", "text": "sitha241 said:Do you plan to put how you made 3d printer?:)\n\nNo point - it's mostly a typical RepRap job -http:\/\/reprap.org\/wiki\/Main_PageOnly unusual part is the electronics, which i made to be autonomous (this type of printer is usually working connected to a PC) -http:\/\/forums.reprap.org\/read.php?13,195726", "thread_id": 14022 }, { "@timestamp": "2023-09-14T07:13:35.982838528Z", "author": "Topper", "date": "2012-08-09T18:48:41+0100", "id": "b4d39accbb4533df3d7de7cdb9b1eb3f", "post_id": "post-251798", "text": "I think yes, because they are in both directions... maybe shiftet by 180 deg.But thats just what i belive :lol:", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.141989888Z", "author": "railfanatic844", "date": "2011-05-21T01:31:26+0100", "id": "3c924ffa8ff98a16e5f91e2587465586", "post_id": "post-219643", "text": "sorry, but i looked in the playback. i run shuttle fleet V4.5 in Orbiter 2010 P1 but i don't see the playback", "thread_id": 14024 }, { "@timestamp": "2023-09-14T07:13:05.08772096Z", "author": "Andy44", "date": "2012-05-02T02:38:39+0100", "id": "ae7f5f09c5b84c911632a6323a1680b4", "post_id": "post-219571", "text": "So you're getting chromatic aberration from your cheap lens trying to collect so many frequencies when it can only focus for a narrow band?---------- Post added at 09:38 PM ---------- Previous post was at 09:37 PM ----------And how come some photos appear monochrome (black and white) and others are in color?", "thread_id": 14022 }, { "@timestamp": "2023-09-14T07:13:36.047334656Z", "author": "IronRain", "date": "2011-11-18T09:56:38+0000", "id": "454292b2d41cae3bb51ad805a7bb59c9", "post_id": "post-251217", "text": "N_Molson said:The great advantage with the RTGs is that you don't have to worry with hardware power-on once in orbit, solar panels deployement & alignement, like it was the case with Phobos-Grunt.\n\nOr all the dust on the solar panels once the spacecraft is on the surface of mars, like with the MERs.", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:05.561535744Z", "author": "Matrix Aran", "date": "2012-06-04T07:55:09+0100", "id": "6876d26f0fb53446064f38a989d88f31", "post_id": "post-220388", "text": "RGClark said:Having personal vehicles to orbit is a pretty significant benefit in regards to making spaceflight routine.Bob Clark\n\nDoesn't space flight have to become routine before people will trust it enough to own personal vehicles to orbit?

That means, about 30 tons of mass. Since we are in the beginning of the development, I even increased the mass budget of it to 40 tons for calculating the propellant demands of the Sky crane.What needs research on my side is how much drag surfaces the Skycrane needs for which terminal velocity. This is an optimization problem: The less drag the Skycrane produces during late reentry and the less mass is allocated to such aerodynamic drag devices, the more fuel mass it needs for landing and lift-off.I already have a nice shape in my head for the skycrane to do such a mission, but this shape adds mission mass by requiring an expendable heat shield for covering the payload, for example an IRDT like inflatable heat shield.", "thread_id": 14083 }, { "@timestamp": "2023-09-14T07:13:05.551003648Z", "author": "RGClark", "date": "2011-09-21T18:50:07+0100", "id": "96828cbc725f65c4c3730a4c3c578173", "post_id": "post-220261", "text": "T.Neo said:...I really do wonder what figures you calculated for reusability that compel you to say things like \"reduce cost by 1 to 2 orders of magnitude\".

The DC-X program did demonstrate this within it's operability envelope, which was low altitude, rocket flight.

Simply because your choice of propellants also means:Different mass ratios and engine performances - while you need less DV (spacecraft independent, only result of the trajectory), your spacecraft will need much more fuel for following the trajectory.A TSTO using the same trajectory to orbit would still brutally outperform the SSTO, the general calculations remain the same.You can't increase the acceleration ad infinitum - throttle limits and wetware limits will make it impossible to get much shorter ascents.But that is an old answer, you used this typical example of American guessing what the simulation results mean pretty often already.

The debate is whether its lower payload would make it worthwhile.\n\nI would say there is much more than little debate. The disadvantages of SSTO- a larger vehicle and more intensive technology, will increase operating as well as development costs.First, a key problem for reducing the cost of spaceflight is that it can only come from reusability.\n\nThat is an extremely simplistic view. There are many ways that launch costs can be reduced, not all include reusability. For example, different schemes for using hardware, different methods of manufacturing, higher manufacturing rates and lower labour costs can all reduce launch costs.Granted, reusability is likely the only way to get a certain specific type of cost reduction, but it also won't work well in certain scenarios (for example, at a certain flight rate it may be more economic to produce large amounts of hardware and expend it rather than a much smaller amount of hardware and reuse it).In addition, reusability can backfire and actually increase costs. It has to be implemented correctly both technology wise and logistically.As I argued before for small SSTO's a large market would be for small privately owned manned SSTO's.\n\nRegardless of the size of this potential market, the disadvantages of SSTO are present for this application too. And perhaps make it particularly unsuited for it (for example, the more advanced engines and higher takeoff weight).Having seperate stages is not a game-ender. And it isn't limited to \"SSTO or TSTO\". There are plenty of ways of potentially doing things- for example, a pop-up first stage is one. An air-launched SSTO is another. Both could improve the physical demands to the point at which such a system could be both developmentally and economically viable.Jon Goff has a series ofvery interesting blog postson methodologies for orbital access.It is only required to marry them together.\n\nOne of the main criticisms, if not the primary criticism, of what you have been suggesting in this thread, is that this particular task is far easier said than done. Rocket development is not easy or cheap.You will have to develop anew a whole lot of components, tweak or re-qualify most if not all existing components... if it gets to the point where it presents only a minor or even negative cost saving, then it obviously doesn't make sense at all.And then to turn it into a reusable SSTO- for example, adding a TPS, landing and on-orbit hardware, as well as a cabin, is a whole other ballgame.The most important accomplishment of SpaceX may turn out to be they showed in stark terms that a privately developed spacecraft can be developed for 1\/10th the cost of government financed ones.\n\nYes, but you can assume either;1. This ~10-fold reduction is universal and applies to any launch vehicle\/spacecraft developed in this supposedly more efficient manner. This means that the cheaper solution remains cheaper regardless of whether it is developed by the government or NuSpace.2. The technology developed determines the cost of development. Arguably SpaceX has been helped in this regard by engine design, stage commonality, extensive testing and small scale experimentation (Falcon 1).In reality, it is a mix of both: a more efficient contracting structure and development culture, combined with technological decisions that reduce cost. It still puts SSTO at a disadvantage.Secondly, as mentioned in this thread a large portion of launch costs are because of operational costs due to the large labor costs as run as a government program. For the space shuttle this is literally thousands of people to run it. This has been recognized for a while. A key part of the proposal to cut launch costs for the VentureStar reusable launcher was to cut majorly this required labor force:\n\nA more technologically challenging vehicle can not only require a larger workforce (due to more work needed for turn-around) but a more highly trained workforce as well. Again something that puts SSTO at a disadvantage.Elon also believes he can cut the costs to space to the $100 to $200 per kg range by reusability. Based on his track record I'd say it's a good bet he's probably right.\n\nWhattrack record? SpaceX may have a good track record at some things, but a pretty poor (or even nonexistant) one at others.Cutting costs to space down to $200\/kg is something thatnobodyhas a track record at (certainly not at achieving such a goal, and I don't believe at attempting it either).

There is no cheaper way to reduce maintenance costs than by throwing everything away. Producing a new vehicle is often cheaper than first evaluating the damage and then repair it.RGClark said:Recall that one of the stated goals of the DC-X and the X-33 programs was to demonstrate this idea of low maintenance and quick turnaround time for space vehicles. The DC-X program did demonstrate this within it's operability envelope, which was low altitude, rocket flight. It would have been great to see for the X-33 if this is doable with vehicles that have to undergo reentry. Perhaps the X-37B will be able to demonstrate this.\n\nAFAIR, it didn't achieve it except on the press releases. It did not do what Armadillo Aerospace also achieves on a fraction of the budget. Launch, land, lift-off again, land. And then get rolled into a hangar and get fixed.The problem with this is, that it only gives the illusion of a quick overhaul. If you would measure the important metrics on 100 flights like that, you would quickly notice that the rocket again spends much more time on the ground than in the air, and the number of people involved repairing it in that time not being much lower than during the manufacture.The only way to extend the time of the \"little maintenance needed\" mission phases is to extend the mean time between failures of the components. And this requires first of all a reduction in the peak performance. You can't go to the short-term limits, because you have now long-term limits. A seal deep inside the engine that has to be replaced after 25 minutes of operation is no longer an option.And that is why I repeat myself again and again to explain you, that a SSTO is, while possible, just a PR stunt, something for the ivory tower, but no economic spacecraft. You can build one. Sure. Just go at the short-term limits of everything. It would not be reusable, but an SSTO that can carry really existing payloads. It would burn itself out during that flight and be on the brink of explosion seconds before MECO, but it would fly.Even just reducing the short-term performance by 5% means even an expendable SSTO can't work. Let alone one that should be reused after flight and needs EDL systems.But by just allowing two stages, you are already getting so much margin for your operations, that you could put more focus on economics and quality and less on performance (old classic engineering, for your SSTO, you would be at performance and quality or performance and economics)A FFSC engine would likely have a 5% lower specific impulse as a comparable staged combustion engine. But its life time would be about 60-100 times longer, and the components in the engine not be forced to be designed for extreme conditions. There are still many problems in the technology (mixing gas generator exhaust and propellant flow, control of such a device) but it is really promising.And thus I just can repeat again: you can dedicate your life building a SSTO. But somebody doing a simple TSTO would not just be done sooner, his second or third generation TSTO would already fly circles around your SSTO because of the faster development cycles.And could maybe one day be a small first with a large second stage, that already is very close to a SSTO. Who knows what technology we will have in 20 years. But if you design an SSTO now, you can't include every new technology. you wouldn't get even to Phase B then, because of your long development cycles. A simpler TSTO could include new technology about every 5 years, similar to civilian aircraft. And still build on flight experience, that you wouldn't have.I don't see much joy in SSTOs from the system engineering point of view. They are a fun challenge for bored engineers and aerospace students to make a Phase 0 study about them, but there is no practical way to design and build one without hell freezing over.---------- Post added at 08:22 PM ---------- Previous post was at 08:18 PM ----------T.Neo said:Even Skylon only gets down to under $200\/kg if it has a relatively high flight rate, which would not materialise without demand.\n\nand remember: The Skylon doesn't even fly yet. While the calculations and planning has been found solid and the company managed to meet their engineering milestones, it does not mean the final flight costs will really be automatically at $200\/kg.Skylon is just a first generation vehicle for Reaction engines. I will not be surprised if things turn out different to the plans today.

(1:31 a.m. on Aug. 6, EDT). After landing, the rover will spend a two-year prime mission studying whether the area has ever offered environmental conditions favorable for life.The spacecraft used two brief thruster firings totaling about 7 seconds to adjust its trajectory at about 10 p.m. PDT on July 28 (1 a.m. on July 29, EDT). This maneuver had been on the mission's schedule since before launch on Nov. 26, 2011. It altered the flight path less than any of the spacecraft's three previous trajectory correction maneuvers on the way from Earth to Mars.The Mars Science Laboratory spacecraft had been on a course in recent weeks that would have hit a point at the top of the Martian atmosphere about 13 miles (21 kilometers) east of the target entry point. On landing day, it can steer enough during its flight through the upper atmosphere to correct for missing the target entry point by a few miles and still land on the intended patch of Mars real estate. The mission's engineers and managers rated the projected 13-mile miss big enough to warrant a correction maneuver.\"The purpose of this maneuver is to move the point at which Curiosity enters the atmosphere by about 13 miles,\" said Tomas Martin-Mur of NASA's Jet Propulsion Laboratory, Pasadena, Calif., chief of the mission's navigation team. \"The first look at telemetry and tracking data afterwards indicates the maneuver succeeded as planned.\"The thruster firings altered the spacecraft's velocity by about one-fortieth of one mile per hour (one centimeter per second). Curiosity will enter Mars' atmosphere at a speed of about 13,200 mph (5,900 meters per second).Opportunities for two further course corrections are scheduled in the final 48 hours before landing, if needed.\"I will not be surprised if this was our last trajectory correction maneuver,\" Martin Mur said of Saturday's event. \"We will be monitoring the trajectory using the antennas of the Deep Space Network to be sure Curiosity is staying on the right path for a successful entry, descent and landing.\"Descent from the top of Mars' atmosphere to the surface will employ bold techniques enabling use of a smaller target area and heavier landed payload than were possible for any previous Mars mission. These innovations, if successful, will place a well-equipped mobile laboratory into a locale especially well-suited for its mission of discovery. The same innovations advance NASA toward capabilities needed for human missions to Mars.As of July 30, the Mars Science Laboratory spacecraft carrying the rover Curiosity will have traveled about 343 million miles (555 million kilometers) of its 352-million-mile (567-million-kilometer) flight to Mars.{...}Universe Today:Curiosity Completes Crucial Course Correction \u2013 1 Week from Mars !Florida Today:A lot hangs in the balance with tricky Mars landingSpaceflight Now:Mars Science Lab fine-tunes path for rover landingDiscovery News:Rover Curiosity Tweaks its Final Mars ApproachSPACE.com:Less Than a Week Remains Before NASA's Biggest Rover Yet Lands on MarsAviation Week:NASA Rover Closing In On Mars To Hunt For Life Clues", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:01.861230848Z", "author": "N_Molson", "date": "2010-04-18T19:15:17+0100", "id": "b9329895ab5a46ddb2d11e6bc9976934", "post_id": "post-217751", "text": "Good news, Voskhod was really the forgotten program of Orbiter !I agree on the fact that the \"Project R-7\" is excellent.

At current layout the truss that supports radiators and part of radiators would be exposed to radiation from reactors. To solve that it would recquire to increase the length of central truss and redesign the layout of radiator panels to have them all in a shadowed area. I also don't want to move main radiators too close to cargo and crew section because there would be multiple gigawats of heat coming from them which might cause some unwanted heating.The rotating crew section looks cool, but is a complex engineering task. If the vessel does not thrust during long cruise periods, it could alternatively go into a \"tumbling pigeon\" mode, rotating head over heels, to give the crew a continous aft acceleration.\n\nThe tumbling wouldn't work because it is envisioned that this vessel would spend most of the cruise time under continous thrust so some sort of centrufuge section is recquired.", "thread_id": 16338 }, { "@timestamp": "2023-09-14T07:13:01.89019264Z", "author": "Orbinaut Pete", "date": "2010-09-20T21:56:19+0100", "id": "b2af2c75b99f77525c80158fd91bc19f", "post_id": "post-217835", "text": "Launch has been pushed into 2011.The first Ariane 5 launch in 2011 \u2013 which will be the 200th Ariane mission \u2013 will boost into orbit the Johannes Kepler ATV (Automated Transfer Vehicle) cargo vessel on a date compatible with the docking slots for the International Space Station (ISS), to be decided by ISS partners.

The upper stage is flying faster, hence it is more difficult to recover.Also interesting is that the payload becomes reduced to about what you can get with an SSTO Falcon 9 first stage using Merlin 1D's with altitude compensation. This would also be cheaper in not having the upper stage and you would not have the problem of returning to the launch base for a lower stage.\n\nRGClark's fictional F9 first stage SSTO, with RGClark's fictional altitude-compensating Merlin engines.

A platinum coated titanium bullet with diamond heat shield tiles would sure also be possible, but for what?\n\nSounds silly to me. :uhh:Experience and skills together are extremely rare and extremely valuable. And they define their price.Also, you have to look at the physical aspects there: The more performance you want, the less tolerances for errors you get. Performance is not just brute force alone, but also effectivity. The more effective your spacecraft should get, the more effective have its parts to get. The whole is maybe more than just the sum of all parts, but still you can't use junk parts alone with only junk skills of your engineers.The math is pretty simple there: The less chamber pressure you have available, the less effective your rocket will be because the exhaust has less energy per kg. At the same time, a higher pressure means a lighter rocket engine for the same thrust. without pumps, you can't get very high chamber pressures, you are limited by the tank pressure and the structural mass.For anything worth talking as SSTO or TSTO, you will need pumps, simply because the limitations of pressure-fed will be ugly. for pumps, you have the same downsizing: the higher your rotor speed, the smaller and lighter a pump can get for the same pressure change and mass flow. Also, for turbo-pumps, a higher rotor speed means the turbine can run faster and be more effective.\n\nWell... yes. I'm not arguing with you there. But I mean, what if you tried to build a modern car engine 70 years ago? It would also be far more expensive than building a (perhaps) less demanding engine. And it would probably be more expensive than building a similar engine today.My point is, I guess, that while the problems never go away, collective technological knowledge, over time, makes it easier to cope with them.Now the annoying part starts as well: For a TSTO, you can compensate a performance drop of your second stage by making the first stage better (or the other way around). But there are limits. A SSTO has no such option, it can only try finding a better planet to launch from.\n\nBut re-engineering the first or second stage doesn't help if it defeats the purpose. If your second stage drops 200 m\/s of exhaust velocity so you can instead have cheaper pumps and you want a better first stage, then you would have to increase your performance and thus cost there.At least it's better juggling those two parts seperately than it is juggling one part at once. It's a pain.But still, which is ideal? Go for as much performance as possible and get higher costs? Or have a poorly-performing cheaper vehicle?If I bring my super-ugly, pressure-fed, steel-walled spacecraft onto the scene, that is just as reliable as the Delta IV but has half the price per kilogram, shouldn't it be adopted by any sane customer, over the Delta?Thus, a first stage, that could for example haul a single low-performance second stage into its launch window, could also maybe carry two higher-performance vehicles with the same payload each. Or you could grow an existing first stage for something obsolete and low-performing into something that can launch two modern second stages. or shrink to become more effective itself.\n\nYes, but you can't just build things like LEGO. Well, you can... but you could have problems.That said, if you want to do something different with your SSTO, you would just have to build a new type of SSTO... just like how people build new types of aircraft. Sure, you don't have the same sort of 'growth options' that you might have with another vehicle, but if cost and reliability are acceptable- and better than the competition- why bother?Though there is of course another path. Strapping a second stage to your SSTO, turning it into a TSTO, and greatly increasing performance.

As shown in Figure 8.2.3-1, combinations of these enhanced wide body booster cores with the evolved upper stage can produce a set of affordable heavy-lift solutions that deliver over 100 mT to LEO. Depending on customer requirements, one can either cluster five wide-body boosters to deliver 107 mT to LEO or, if even more performance is required, four wide body boosters can be clustered around an 8.4-m diameter core to deliver 140 mT to LEO. Both of these booster combinations are paired with the evolved upper stage and a new 8.4-m (27.6-ft) payload fairing.The 5-m diameter booster tank is derived from Delta IV\u2019s existing 5-m tank and is powered by a pair of RD-180 engines. The 8.4-m diameter core is derived from the Space Shuttle\u2019s external tank and powered by five RD-180 engines. Both the 5-m and 8.4-m diameter booster cores can fly either as a single core, with strap on Aerojet SRBs (1 to 6), or as multi-core combinations with the use of either two or four 5-m, wide-body liquid rocket boosters (LRBs). The single core configurations provide ideal, highly reliable launch vehicles capable of supporting launch of large crew capsules. These super-heavy Atlas derivatives allow Atlas to support a broad payload range (9mT to 140 mT to LEO) with a common vehicle family.\n\n", "thread_id": 14084 }, { "@timestamp": "2023-09-14T07:13:01.86502272Z", "author": "Columbia42", "date": "2010-06-17T00:41:49+0100", "id": "3dd02825e9a1217ffbe6279474857579", "post_id": "post-217769", "text": "Albatros said:I can pixel and programm in PASCAL, but don't knew anything about a mesh.

In one day, on July 28, data from Voyager 1's cosmic ray instrument showed the level of high-energy cosmic rays originating from outside our solar system jumped by five percent. During the last half of that same day, the level of lower-energy particles originating from inside our solar system dropped by half. However, in three days, the levels had recovered to near their previous levels.A third key sign is the direction of the magnetic field, and scientists are eagerly analyzing the data to see whether that has, indeed, changed direction. Scientists expect that all three of these signs will have changed when Voyager 1 has crossed into interstellar space. A preliminary analysis of the latest magnetic field data is expected to be available in the next month.\"These are thrilling times for the Voyager team as we try to understand the quickening pace of changes as Voyager 1 approaches the edge of interstellar space,\" said Edward Stone, the Voyager project scientist based at the California Institute of Technology, Pasadena, Calif. \"We are certainly in a new region at the edge of the solar system where things are changing rapidly.

Scientists expect that the lower-energy particles will drop close to zero when Voyager 1 finally crosses into interstellar space.\"The increase and the decrease are sharper than we've seen before, but that's also what we said about the May data,\" Stone said. \"The data are changing in ways that we didn't expect, but Voyager has always surprised us with new discoveries.\"Voyager 1, which launched on Sept. 5, 1977, is 11 billion miles (18 billion kilometers) from the sun.

This connection allows lower-energy charged particles that originate from inside our heliosphere -- or the bubble of charged particles the sun blows around itself -- to zoom out and allows higher-energy particles from outside to stream in.

The direction of these magnetic field lines is predicted to change when Voyager breaks through to interstellar space. The new results were described at the American Geophysical Union meeting in San Francisco on Monday.\"Although Voyager 1 still is inside the sun's environment, we now can taste what it's like on the outside because the particles are zipping in and out on this magnetic highway,\" said Edward Stone, Voyager project scientist based at the California Institute of Technology, Pasadena. \"We believe this is the last leg of our journey to interstellar space.

In this region, the stream of charged particles from the sun, known as the solar wind, abruptly slowed down from supersonic speeds and became turbulent. Voyager 1's environment was consistent for about five and a half years. The spacecraft then detected that the outward speed of the solar wind slowed to zero.{colsp=2}Click on images for details\u200b|Plasma Flow Near Voyager 1\u200bThis artist's concept shows plasma flows around NASA's Voyager 1 spacecraft as it approaches interstellar space.Image credit: NASA\/JPL-Caltech\/JHUAPL\u200b|Location of Low-Energy Charged Particle Instrument\u200bThis graphic shows the NASA's Voyager 1 spacecraft and the location of its low-energy charged particle instrument.

Who cares, it is fictional!

You're right saying speed limit is only for objects, but this is because space doesn't move: when you say space is moving at C around the black holes, this is not correct, space simply is bent very deeply. Inside the singularity, space do not move beyond C, it's simply bent at the infinity, it's something like \"void\", wich may get to a white hole, let's say. You can't escape from the singularity because you fall on that void, not because the space is travelling at a velocity greater then C.So the sentence of T.Neo it's correct: nothing can go beyond C.This is easier to understand if you don't think at C as a weird limit, but you understand why this limit exists. It is not properly a limit, it's simply a mathematical way to explain how stuff works in the space-time environment, wich if looked from the outside, it's a static 4-dimensional thing.Just imagine space has a sort of friction.In a certain sense you can say space is bending itself with a certain velocity, but relatively to what?

The research will aid in planning for future human missions to the Red Planet.Curiosity launched on Nov. 26 from Cape Canaveral, Fla., aboard the Mars Science Laboratory. The rover carries an instrument called the Radiation Assessment Detector (RAD) that monitors high-energy atomic and subatomic particles from the sun, distant supernovas and other sources.These particles constitute radiation that could be harmful to any microbes or astronauts in space or on Mars. The rover also will monitor radiation on the surface of Mars after its August 2012 landing.\"RAD is serving as a proxy for an astronaut inside a spacecraft on the way to Mars,\" said Don Hassler, RAD's principal investigator from the Southwest Research Institute in Boulder, Colo. \"The instrument is deep inside the spacecraft, the way an astronaut would be. Understanding the effects of the spacecraft on the radiation field will be valuable in designing craft for astronauts to travel to Mars.\"Click on image for details\u200bThis is an artist's concept of NASA's Mars Science Laboratory spacecraft during its cruise phase between launch and final approach to Mars. The spacecraft includes a disc-shaped cruise stage (on the left) attached to the aeroshell. The spacecraft's rover (Curiosity) and descent stage are tucked inside the aeroshell.\u200bImage credit: NASA\/JPL-Caltech\u200bRelated Video\u200bPrevious monitoring of energetic-particle radiation in space has used instruments at or near the surface of various spacecraft. The RAD instrument is on the rover inside the spacecraft and shielded by other components of Mars Science Laboratory, including the aeroshell that will protect the rover during descent through the upper atmosphere of Mars.Spacecraft structures, while providing shielding, also can contribute to secondary particles generated when high-energy particles strike the spacecraft. In some circumstances, secondary particles could be more hazardous than primary ones.These first measurements mark the start of the science return from a mission that will use 10 instruments on Curiosity to assess whether Mars' Gale Crater could be or has been favorable for microbial life.\"While Curiosity will not look for signs of life on Mars, what it might find could be a game-changer about the origin and evolution of life on Earth and elsewhere in the universe,\" said Doug McCuistion, director of the Mars Exploration Program at NASA Headquarters in Washington. \"One thing is certain: The rover's discoveries will provide critical data that will impact human and robotic planning and research for decades.\"As of 9 a.m. PST (noon EST) on Dec. 14, the spacecraft will have traveled 31.9 million miles (51.3 million kilometers) of its 352-million-mile (567-million-kilometer) flight to Mars. The first trajectory correction maneuver during the trip is being planned for mid-January.{...}NASA Press Release:RELEASE : 11-414 - NASA Mars-Bound Rover Begins Research in SpaceSpaceflight Now:Mars-bound rover previewing the experience for astronautsDiscovery News:Mars Rover Curiosity Begins Space Radiation Work", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:06.038837248Z", "author": "Artlav", "date": "2010-05-03T16:50:15+0100", "id": "d43d4c4e74db6b1da5cf165ebdbc72ed", "post_id": "post-221367", "text": "Andy44 said:The general is complaining because he can't find enough fit cannon fodder.\n\nCuriously, it's something like that here too.

Confirmation was received today that the spacecraft accepted the commands. The change will allow the 34-year-old spacecraft to reduce the amount of power it requires to operate and use previously unused thrusters as it continues its journey toward interstellar space, beyond our solar system.Launched in 1977, Voyager 1 and Voyager 2 are each equipped with six sets, or pairs, of thrusters to control their movement. These include three pairs of primary thrusters and three backup, or redundant, pairs. Voyager 2 is currently using the two pairs of backup thrusters that control the pitch and yaw motion of the spacecraft. Switching to the backup thruster pair that controls roll motion will allow engineers to turn off the heater that keeps the fuel line to the primary thruster warm. This will save about 12 watts of power. The spacecraft's power supply now provides about 270 watts of electricity. By reducing its power usage, the spacecraft can continue to operate for another decade even as its available power continues to decline.The thrusters involved in this switch have fired more than 318,000 times. The backup pair has not been used in flight. Voyager 1 changed to the backup for this same component after 353,000 pulses in 2004 and is now using all three sets of its backup thrusters.Voyager 2 will relay the results of the switch back to Earth on Nov. 13. The signal will arrive on Earth on Nov. 14. Voyager 2 is currently located about 9 billion miles (14 billion kilometers) from Earth in the \"heliosheath\" -- the outermost layer of the heliosphere where the solar wind, which streams out from the sun, is slowed by the pressure of interstellar gas.{...}", "thread_id": 14169 }, { "@timestamp": "2023-09-14T07:13:36.063967488Z", "author": "boogabooga", "date": "2011-11-26T15:50:29+0000", "id": "b086d4605e8d5583cd616f89479c0299", "post_id": "post-251275", "text": "N_Molson said:Passive Thermal Control.

The left-eye Mastcam provides broader context through a medium-angle lens. Each can acquire thousands of full-color images and store them in an eight-gigabyte flash memory. Both cameras are also capable of recording high-definition video at about eight frames per second. Combining information from the two eyes can yield 3-D views of the telephoto part of the scene.Motivation to put telephoto capability in Curiosity's main science imaging instrument grew from experience with NASA's Mars Exploration Rover Opportunity and its studies of an arena-size crater in 2004. The science camera on that rover's mast, which can see details comparably to what a human eye can see at the same distance, showed intriguing patterns in the layers of Burns Cliff inside Endurance Crater.\"We tried to get over and study it, but the rover could not negotiate the steep slope,\" recalled Mastcam Principal Investigator Michael Malin, of Malin Space Science Systems, San Diego. \"We all desperately coveted a telephoto lens.\" NASA selected his Mastcam proposal later that year for the Mars Science Laboratory rover.The telephoto Mastcam, called \"Mastcam 100\" for its 100-millimeter focal-length lens, provides enough resolution to distinguish a basketball from a football at a distance of seven football fields, or to read \"ONE CENT\" on a penny on the ground beside the rover. Its images cover an area about six degrees wide by five degrees tall.Click on image for details\u200bThe left eye of the two-camera Mast Camera (Mastcam) instrument on NASA's Mars rover Curiosity took the images combined into this mosaic of the rover's upper deck. Image credit: NASA\/JPL-Caltech\/Malin Space Science Systems\u200bIts left-eye partner, called \"Mastcam 34\" for its 34-millimeter lens, catches a scene three times wider -- about 18 degrees wide and 15 degrees tall -- with each exposure.Researchers will use the Mastcams and nine other science instruments on Curiosity to study past and present environments in a carefully chosen area of Mars. They will assess whether conditions have been favorable for life and favorable for preserving evidence about whether life has existed there. Mastcam imaging of the shapes and colors of landscapes, rocks and soils will provide clues about the history of environmental processes that have formed them and modified them over time. Images and videos of the sky will document contemporary processes, such as movement of clouds and dust.Previous color cameras on Mars have taken a sequence of exposures through different color filters to be combined on Earth into color views. The Mastcams record color the same way consumer digital cameras do: They have a grid of tiny red, green and blue squares (a \"Bayer pattern\" filter) fitted over the electronic light detector (the charge-coupled device, or CCD). This allows the Mastcams to get the three color components over the entire scene in a single exposure.Mastcam's color-calibration target on the rover deck includes magnets to keep the highly magnetic Martian dust from accumulating on portions of color chips and white-gray-balance reference chips. Natural lighting on Mars tends to be redder than on Earth due to dust in Mars' atmosphere. \"True color\" images can be produced that incorporate that lighting effect -- comparable to the greenish look of color-film images taken under fluorescent lights on Earth without a white-balancing adjustment. A white-balance calculation can yield a more natural look by adjusting for the tint of the lighting, as the human eye tends to do and digital cameras can do. The Mastcams are capable of producing both true-color and white-balanced images.Besides the affixed red-green-blue filter grid, the Mastcams have wheels of other filters that can be rotated into place between the lens and the CCD. These include science spectral filters for examining the ground or sky in narrow bands of visible-light or near-infrared wavelengths. One filter on each camera allows it to look directly at the sun to measure the amount of dust in the atmosphere, a key part of Mars' weather.\"Something we're likely to do frequently is to look at rocks and features with the Mastcam 34 red-green-blue filter, and if we see something of interest, follow that up with the Mastcam 34 and Mastcam 100 science spectral filters,\" Malin said. \"We can use the red-green-blue data for quick reconnaissance and the science filters for target selection.\"When Curiosity drives to a new location, Mastcam 34 can record a full-color, full-circle panorama about 60 degrees tall by taking 150 images in about 25 minutes. Using Mastcam 100, the team will be able to broaden the swath of terrain evaluated on either side of the path Curiosity drives, compared to what has been possible with earlier Mars rovers. That will help with selection of the most interesting targets to approach for analysis by Curiosity's other instruments and will provide additional geological context for interpreting data about the chosen targets.The Mastcams will provide still images and video to study motions of the rover -- both for science, such as seeing how soils interact with wheels, and for engineering, such as aiding in use of the robotic arm. In other videos, the team may use cinematic techniques such as panning across a scene and using the rover's movement for \"dolly\" shots.Each of the two-megapixel Mastcams can take and store thousands of images, though the amount received on Earth each day will depend on how the science team chooses priorities for the day's available data-transmission volume. Malin anticipates frequent use of Mastcam \"thumbnail\" frames -- compressed roughly 150-by-150-pixel versions of each image -- as an index of the full-scale images held in the onboard memory.Malin Space Science Systems built the Mastcam instrument and will operate it. The company's founder, Michael Malin, participated in NASA's Viking missions to Mars in the 1970s, provided the Mars Orbiter Camera for NASA's Mars Global Surveyor mission, and is the principal investigator for both the Context Camera and the Mars Color Imager on NASA's Mars Reconnaissance Orbiter.The science team for Mastcam and two other instruments the same company provided for Curiosity includes the lead scientist for the mast-mounted science cameras on Mars rovers Spirit and Opportunity (James Bell of Arizona State University); the lead scientist for the mast camera on NASA's Phoenix Mars Lander (Mark Lemmon of Texas A&M University); James Cameron, director of such popular movies as \"Titanic\" and \"Avatar\"; and 17 others with expertise in geology, soils, frost, atmosphere, imaging and other topics.Mastcam 100 and Mastcam 34 were installed onto Curiosity in 2010. Until March 2011, a possibility remained open that they might be replaced with a different design: two identical zoom cameras. A zoom camera has adjustable focal length, to change from wider-angle to telephoto or vice-versa. That design had been Malin's original proposal. NASA changed the plan to two different fixed-focal-length cameras in 2007 as a cost-cutting measure that preserves the capability for meeting the science goals of the mission and the instrument. The agency funded a renewed possibility for using the zoom-camera design in 2010, but the zoom development presented challenges that could not be fully overcome with enough time for required testing on the rover.Mastcam 34 took images for a mosaic showing Curiosity's upper deck during tests in March 2011 inside a chamber simulating Mars surface temperature and air pressure. Testing of the rover at NASA's Jet Propulsion Laboratory, Pasadena, Calif., will wrap up in time for shipping the rover to NASA Kennedy Space Center in June. Testing and other launch preparations will continue there.

When extending just one panel, the vehicle pushes on the panel, so the panel pushes on the vehicle. The force of the panel on the vehicle causes a torque about the CoG of the vehicle. You can see this by taking the cross product of the force from the panel with the vector from the vehicle's CoG to the panel attachment point. Having said that, the subsequent deceleration should apply the opposite torque (or a lower torque for a longer time).Thinking about in terms of angular momentum, if the vehicle has zero angular momentum then that must be conserved.

The answer, scientists know, is blowing in the wind. It's just a matter of getting NASA's Voyager 1 spacecraft in the right orientation to detect it.To enable Voyager 1's Low Energy Charged Particle instrument to gather these data,the spacecraft performed a maneuver on March 7 that it hadn't done for 21 years, except in a preparatory test last month.At 9:10 a.m. PST (12:10 p.m. EST),humanity's most distant spacecraft rolled 70 degrees counterclockwise as seen from Earth from its normal orientation and held the position by spinning gyroscopes for two hours, 33 minutes. The last time either of the two Voyager spacecraft rolled and stopped in a gyro-controlled orientation was Feb. 14, 1990, when Voyager 1 snapped a family portrait of the planets strewn like tiny gems around our sun (http:\/\/photojournal.jpl.nasa.gov\/catalog\/PIA00451).\"Even though Voyager 1 has been traveling through the solar system for 33 years, it is still a limber enough gymnast to do acrobatics we haven't asked it to do in 21 years,\"said Suzanne Dodd, Voyager project manager, based at NASA's Jet Propulsion Laboratory in Pasadena, Calif.\"It executed the maneuver without a hitch, and we look forward to doing it a few more times to allow the scientists to gather the data they need.\"The two Voyager spacecraft are traveling through a turbulent area known as the heliosheath. The heliosheath is the outer shell of a bubble around our solar system created by the solar wind, a stream of ions blowing radially outward from the sun at a million miles per hour. The wind must turn as it approaches the outer edge of the bubble where it makes contact with the interstellar wind, which originates in the region between stars and blows by our solar bubble.In June 2010, when Voyager 1 was about 17 billion kilometers (about 11 billion miles) away from the sun, data from the Low Energy Charged Particle instrument began to show that the net outward flow of the solar wind was zero. That zero reading has continued since. The Voyager science team doesn't think the wind has disappeared in that area. It has likely just turned a corner. But does it go up, down or to the side?\"Because the direction of the solar wind has changed and its radial speed has dropped to zero, we have to change the orientation of Voyager 1 so the Low Energy Charged Particle instrument can act like a kind of weather vane to see which way the wind is now blowing,\"said Edward Stone, Voyager project manager, based at the California Institute of Technology, Pasadena.\"Knowing the strength and direction of the wind is critical to understanding the shape of our solar bubble and estimating how much farther it is to the edge of interstellar space.\"Voyager engineers performed a test roll and hold on Feb. 2 for two hours, 15 minutes. When data from Voyager 1 were received on Earth some 16 hours later, the mission team verified the test was successful and the spacecraft had no problem in reorienting itself and locking back onto its guide star, Alpha Centauri.The Low Energy Charged Particle instrument science team confirmed that the spacecraft had acquired the kind of information it needed, and mission planners gave Voyager 1 the green light to do more rolls and longer holds. There will be five more of these maneuvers over the next seven days, with the longest hold lasting three hours 50 minutes. The Voyager team plans to execute a series of weekly rolls for this purpose every three months.The success of the March 7 roll and hold was received at JPL at 1:21 a.m. PST (4:21 a.m. EST) on March 8. But it will take a few months longer for scientists to analyze the data.\"We do whatever we can to make sure the scientists get exactly the kinds of data they need, because only the Voyager spacecraft are still active in this exotic region of space,\"said Jefferson Hall, Voyager mission operations manager at JPL.\"We were delighted to see Voyager still has the capability to acquire unique science data in an area that won't likely be traveled by other spacecraft for decades to come.\"Voyager 2 was launched on Aug. 20, 1977. Voyager 1 was launched on Sept. 5, 1977. On March 7, Voyager 1 was 17.4 billion kilometers (10.8 billion miles) away from the sun. Voyager 2 was 14.2 billion kilometers (8.8 billion miles) away from the sun, on a different trajectory.The solar wind's outward flow has not yet diminished to zero where Voyager 2 is exploring, but that may happen as the spacecraft approaches the edge of the bubble in the years ahead.\n\nThis is very impressive.", "thread_id": 14169 }, { "@timestamp": "2023-09-14T07:13:36.022045952Z", "author": "orb", "date": "2011-11-02T16:36:19+0000", "id": "06979fb0339ede68f705fa6e022f3e13", "post_id": "post-251206", "text": "Florida Today - The Flame Trench:Wind delays rover's move to launch pad", "thread_id": 16265 }, { "@timestamp": "2023-09-14T07:13:02.24323456Z", "author": "mc_", "date": "2010-04-17T14:31:58+0100", "id": "a938c2c517c54bbf443dcd982bb37dc8", "post_id": "post-218037", "text": "You need to customize the craters around your bases.

I think older versions of DirectX also had a system where old APIs were emulated on top of the latest version. This really adds only alittlebit of extra work, and that isn't so important generally, because older games are designed for having less CPU time. The alternative would be to let each version of DirectX have its own driver, which would mean a lot more work for driver developers, which would make it less likely that a certain combination of DirectX version + hardware will be supported.Yes, the war between DirectX and OpenGL does hurt the industry, or, IMHO, DirectX hurts the industry.

Therefore, [math]u_1^0 = \\frac{1}{\\sqrt{g_{00}(r_1)}}[\/math] and [math]u_2^0 = \\frac{1}{\\sqrt{g_{00}(r_2)}}[\/math].So, [math]f = g_{\\mu\\nu}(r_1) u_1^\\mu f^\\nu(r_1) = g_{00}(r_1) u_1^0 f^0(r_1) = \\sqrt{g_{00}(r_1)}f^0(r_1)[\/math] and [math]f' = g_{\\mu\\nu}(r_2) u_2^\\mu f^\\nu = g_{00}(r_2) u_2^0 f^0(r_2) = \\sqrt{g_{00}(r_2)}f^0(r_2)[\/math], where f' is the frequency received by the second observer.Now, from what I said earlier, [math]g_{00}(r_1)f^0(r_1) = g_{00}(r_2)f^0(r_2)[\/math], because [math]g_{00}f^0 = g\\left( \\frac{\\partial}{\\partial t},f^\\mu\\right)[\/math]. Hence:[math]\\sqrt{g_{00}(r_1)}f = \\sqrt{g_{00}(r_2)}f'[\/math]This means I was wrong, and in reality the constant quantity is [math]\\sqrt{1-\\frac{2M}{r}}f[\/math].", "thread_id": 13925 }, { "@timestamp": "2023-09-14T07:13:06.30803968Z", "author": "TSPenguin", "date": "2010-05-05T13:35:53+0100", "id": "99a205cc4ffdcd57f12b0c5412492c51", "post_id": "post-221608", "text": "The big problem with tires that need to work on multiple bodies is the differing gravity.

Given that f(2) = 3, what is f(3)?\n\nHere is my solution:f'(x) = 2x [since the slope is twice the x value]f(x) = integral (2x dx)= x^2 + cUse the initial condition f(2) = 3 to solve for c:4+c=3c=-1so the function is f(x) = x^2 - 1You plug three in it: f(3) = 9-1 to get 8.\n\nI got the right answer.

Responders in the physics forum stated that generally speaking the method the class used doesn't hold, but it holds for quadratics. I have already tried proving this myself. I am not getting any good results. So I asked whether someone else can provide the proof.What I came up with makes no sense.

A change in the direction of the magnetic field is the last critical indicator of reaching interstellar space and that change of direction has not yet been observed.\"To learn more about the current status of the Voyager mission, visit:http:\/\/www.jpl.nasa.gov\/news\/news.php?release=2012-381{...}AGU:Voyager 1 has entered a new region of space, sudden changes in cosmic rays indicate20 March 2013AGU Release No. 13-11For Immediate ReleaseWASHINGTON \u2013 Thirty-five years after its launch, Voyager 1 appears to have travelled beyond the influence of the Sun and exited the heliosphere, according to a new study appearing online today.The heliosphere is a region of space dominated by the Sun and its wind of energetic particles, and which is thought to be enclosed, bubble-like, in the surrounding interstellar medium of gas and dust that pervades the Milky Way galaxy.On August 25, 2012, NASA's Voyager 1 spacecraft measured drastic changes in radiation levels, more than 11 billion miles from the Sun. Anomalous cosmic rays, which are cosmic rays trapped in the outer heliosphere, all but vanished, dropping to less than 1 percent of previous amounts. At the same time, galactic cosmic rays \u2013 cosmic radiation from outside of the solar system \u2013 spiked to levels not seen since Voyager's launch, with intensities as much as twice previous levels.The findings have been accepted for publication in Geophysical Research Letters, a journal of the American Geophysical Union.\"Within just a few days, the heliospheric intensity of trapped radiation decreased, and the cosmic ray intensity went up as you would expect if it exited the heliosphere,\" said Bill Webber, professor emeritus of astronomy at New Mexico State University in Las Cruces. He calls this transition boundary the \"heliocliff.\"In the GRL article, the authors state: \"It appears that [Voyager 1] has exited the main solar modulation region, revealing [hydrogen] and [helium] spectra characteristic of those to be expected in the local interstellar medium.\"However, Webber notes, scientists are continuing to debate whether Voyager 1 has reached interstellar space or entered a separate, undefined region beyond the solar system.\"It's outside the normal heliosphere, I would say that,\" Webber said. \"We're in a new region.

For 99% of the work, the Design Pattern cover it all good. The remaining 1% are the reason why good programmers are so rare.Also, being able to read the code has a higher priority than writing fast programs. If you don't know if you can find bugs in the best code, use a slightly worse one for the start and implement the better code as option once you have a reference for debugging.And: Don't worry if 99% of your code is bureaucracy to make the important 1% of the code look good. Smart ways to handle your data and get the data into action are critical. Such infrastructure is just normal. For example it is often harder and much more code to read information for a small game or part of a game from configuration files, instead of hard coding it. But the work pays out when you extend this part, and have a clean separation of data and code to work with.And the most important rule: Don't waste a single second thinking that you have now learned enough and can do it all. There is always unwritten code waiting for you, and especially games depend a lot on the programmer being able to find non-standard solutions for non-standard problems.

As far as disappointment goes, It's their fault if they do not properly research what the game is about and just assume it's a shoot 'em up Xwing game. There's a reason why it's called a \"sim\";)Although, maybe in my description blurb on my Xfire post I should be a little more clear on how complex it is.And I think now is as good a time as any to promote the game. OMP has a long,longway to go before it's even really worth playing beyond the beta test. And we have no idea when the new Orbiter client will be out, and it doesn't make the game any more accessible for newbies as the seperation between Orbiter and Orbiter no graphics makes it that much more complex. Beyond cripser textures, and the new graphics plug in system, we really don't know any strong facts about what the next version will include.Besides, it might take a while to get it supported.

Imagine that whenever you have the \"ChatMFD\" active, you are given a list of orbinauts\/ships and their distance (or light-time) from you. They don't have to be at the same MJD as you, just \"in the neighborhood\". You can hail one (or more) and exchange pleasantries, technical details, opinions on nearby watering holes, etc. Maybe you can show your face (especially if you have a costume or simpit), or speak in real-time (if not too time-lagged).This isn't quite multi-player, since there isn't any play, but it might add a social dimension currently lacking, for those who want it. Eliminating the time-sync requirement makes the implementation nearly as simple as an IRC chat. Of course, people might be talking about two planets near to themselves, when each is only near to one orbinaut, depending on their MJDs. That shouldn't adversely affect social interaction.Building on this capability, the ability to sync the MJD and other aspects of a scenario among two (or more) ships could enable orbinauts to fly cooperative (or competitive) missions in a common world, such as maneuvering near the ISS together.These two steps toward multi-player are a far cry from what some have proposed, but the \"real world\" (even in simulation) will always constrain what we can do.

Smart ways to handle your data and get the data into action are critical. Such infrastructure is just normal.

But the work pays out when you extend this part, and have a clean separation of data and code to work with.\n\n:goodposting: Well-said! Sometimes you necessarily end up with a lot of code in your framework (which is \"hidden\") just so that yourmaincode (which is not \"hidden\") is easy to extend and reuse. Like Urwumpe said, that often takes more work up front and results in more total lines of code, but it pays off big-time later because once your core framework is finished and debugged you don't have to mess with it just to extend yourmaincode. So don't feel bad about having to write a lot of \"hidden\" code just so your \"main\" code is easy to understand and extend. Complex programs require lots of code -- there is no way around that. And the cleaner you can make the \"non-hidden\" part of your code, the better -- even if that means a more complex \"hidden\" framework underneath it. :thumbup:", "thread_id": 14125 }, { "@timestamp": "2023-09-14T07:13:34.913684992Z", "author": "jinglesassy", "date": "2010-09-03T22:01:56+0100", "id": "61a2066634e5200b1b9d90bb78a96a81", "post_id": "post-249854", "text": "Lets check my list764 Ummus dead291 From burning up on reentry138 From hitting the ground304 From sending them on reentry without any heat shield in earths atmosphere31 From \"other\" reasons34 DG-IV's destroyed29 From failed reentry(Man i suck at reentry)5 Parachuting \"tests\"15 XR1 destroyed14 on reentry1 Burning engines for along time and ramming into the moon at 15 km\/s13 XR2 destroyed5 From reentry7 From aerobatics1 Docking on the ground with an XR5(dont ask how long it took to get it....)39 XR530 Reentry5 Aerobatics1 Docking on the ground4 Id rather not sayOver 400 shuttles toasty in the atmosphere or similar incidents208 AMSO Saturn V lost from manual control309 LEM made into a crater on the lunar surface54 Command modules lost in reentry97 Service modules from failuresAnd many more ships that i haven't tracked.", "thread_id": 16171 }, { "@timestamp": "2023-09-14T07:13:02.4855168Z", "author": "Graham2001", "date": "2010-04-19T13:21:40+0100", "id": "74780f3f936ca733d1f941912d3b8b4c", "post_id": "post-218409", "text": "KosmoKen said:Are you using an add-on that requires Hi-Res KCS?

Remember a trillion dollars is a thousand billion dollars. That is a lot of money.The cost estimates for the ISS are between 35 to 160 billion USD. A lot of that is on orbit operations, in the case of an ISV you'd deal with those seperately. A large percentage of theconstructioncosts are taken up by launch costs. Presumably the launch techology of the Avatar future world enables far lower surface\/orbit costs than with current technology, and indeed, far lower surface\/orbit costs than the ridiculously expensive STS.Also remember that while the vehicle is large, it would actually be quite light, as the average density is low. The rear shields are very thin and thus light, the truss is lightweight, and even the pressurised sections are made of inflatable modules (or at least, they seem to be). The engines and radiators would probably be pretty dense though, they'd easily be the heaviest part of the ship (and theylooklike the heaviest part of the ship...). It would be pretty funny, with low surface\/orbit costs you might actually have more money spent on constructing such a behemoth on-orbit than money spent getting the components there.\"The US has more\" makes no sense. It's a vehicle owned by a business, that exists to turn a profit. It isn't some science mission with no economic return. Besides, the US operates and owns a lot of vehicles, that are built by contractors anyway, and there are a lot of instances where corporations actually own facilities, that are utilized by the government.Maybe there is government, or international (more probable) funding for the start-up, but these ships are built to pay for themselves many times over. With the kind of revenue the RDA makes with the maguffinite Unobtanium, they should easily be able to afford such a vehicle.There are other problems though, mainly the fact that the antimatter and laser array needed to propel such a ship would be of utterly epic proportions, and would be highly unlikely to cost little enough for the operation to turn a profit.

My apologies, but this could easily delay the release by a week or two, or even more. Making the actual flight recordings isn't that time consuming, but annotating them takes far longer than flying them.Keep in mind that so far we've tried to keep things at a \"simple, yet effective\" level that can be applied to many situations, rather than a specific \"here's how you do this particular flight\". The \"Advanced Concepts\" tutorial I'm working on is an exception, it values efficiency more than simplicity, and is much more complex than the first version.Both the tutorials you've requested involve the same principles, and doing both would be repetitive. Our goal (or at least my goal) is to teach you the basic principles that can be applied to a wide range of circumstances. While I've made a real effort to reduce spaceflight to a repeatable process (taking a cue from modern manufacturing processes) without needing any external math, it isn't really possible to cover every situation - some effort on the user's part is expected to figure out specifics. A \"paint by the numbers\" approach isn't really practical if we want to release this tutorial any time this year, covering every possible situation. I'll do my best, but I'd rather teach you how to get to the Moon with an inclination you choose rather than teach you how to get to a particular station orbiting the Moon. In other words, the focus is on general practices, rather than specifics. One of the real joys of Orbiter (for me at least) is figuring out how to apply general theories to an actual scenario.If there is a real demand, I'll put together individual tutorials covering specific missions such as these, and release them separately. Keep in mind that I have the inconvenience of a real life that limits the time I can spend doing this, so please be patient.I'll be putting in over 60 hours of time just doing the tutorials already planned - partly figuring out how to do these things in the first place, and mostly figuring out how to make it understandable (and repeatable) to other Orbinauts. I'd rather spend the time expanding the tutorial on Map program, which is the lest understood, but by far most powerful, feature of IMFD, than doing another \"mission specific\" tutorial.If I do my job right, you'll be able to figure out how to do anything you want without \"handholding\" you through it.

The spacecraft, which has been flying for 40 years, relies on small devices called thrusters to orient itself so it can communicate with Earth. These thrusters fire in tiny pulses, or \"puffs,\" lasting mere milliseconds, to subtly rotate the spacecraft so that its antenna points at our planet. Now, the Voyager team is able to use a set of four backup thrusters, dormant since 1980.\"With these thrusters that are still functional after 37 years without use, we will be able to extend the life of the Voyager 1 spacecraft by two to three years,\" said Suzanne Dodd, project manager for Voyager at NASA's Jet Propulsion Laboratory, Pasadena, California.Since 2014, engineers have noticed that the thrusters Voyager 1 has been using to orient the spacecraft, called \"attitude control thrusters,\" have been degrading. Over time, the thrusters require more puffs to give off the same amount of energy. At 13 billion miles from Earth, there's no mechanic shop nearby to get a tune-up.The Voyager team assembled a group of propulsion experts at NASA's Jet Propulsion Laboratory, Pasadena, California, to study the problem. Chris Jones, Robert Shotwell, Carl Guernsey and Todd Barber analyzed options and predicted how the spacecraft would respond in different scenarios. They agreed on an unusual solution: Try giving the job of orientation to a set of thrusters that had been asleep for 37 years.\u201cThe Voyager flight team dug up decades-old data and examined the software that was coded in an outdated assembler language, to make sure we could safely test the thrusters,\" said Jones, chief engineer at JPL.In the early days of the mission, Voyager 1 flew by Jupiter, Saturn, and important moons of each. To accurately fly by and point the spacecraft's instruments at a smorgasbord of targets, engineers used \"trajectory correction maneuver,\u201d or TCM, thrusters that are identical in size and functionality to the attitude control thrusters, and are located on the back side of the spacecraft. But because Voyager 1's last planetary encounter was Saturn, the Voyager team hadn't needed to use the TCM thrusters since November 8, 1980. Back then, the TCM thrusters were used in a more continuous firing mode; they had never been used in the brief bursts necessary to orient the spacecraft.All of Voyager's thrusters were developed by Aerojet Rocketdyne. The same kind of thruster, called the MR-103, flew on other NASA spacecraft as well, such as Cassini and Dawn.On Tuesday, Nov. 28, 2017, Voyager engineers fired up the four TCM thrusters for the first time in 37 years and tested their ability to orient the spacecraft using 10-millisecond pulses. The team waited eagerly as the test results traveled through space, taking 19 hours and 35 minutes to reach an antenna in Goldstone, California, that is part of NASA's Deep Space Network.Lo and behold, on Wednesday, Nov. 29, they learned the TCM thrusters worked perfectly -- and just as well as the attitude control thrusters.\u201cThe Voyager team got more excited each time with each milestone in the thruster test. The mood was one of relief, joy and incredulity after witnessing these well-rested thrusters pick up the baton as if no time had passed at all,\" said Barber, a JPL propulsion engineer.The plan going forward is to switch to the TCM thrusters in January. To make the change, Voyager has to turn on one heater per thruster, which requires power -- a limited resource for the aging mission. When there is no longer enough power to operate the heaters, the team will switch back to the attitude control thrusters.The thruster test went so well, the team will likely do a similar test on the TCM thrusters for Voyager 2, the twin spacecraft of Voyager 1. The attitude control thrusters currently used for Voyager 2 are not yet as degraded as Voyager 1's, however.\n\n", "thread_id": 14169 }, { "@timestamp": "2023-09-14T07:13:34.84601728Z", "author": "Polaris", "date": "2010-08-23T01:39:19+0100", "id": "bfaf6b4a00408a43f5a44520c57eccbd", "post_id": "post-249728", "text": "Welcome, Claude!

ATV hooks were closed at 4:06 PM GMT, SM hooks at 4:09 PM GMT. Congratulations, ESA! [At ~10:53 AM GMT, the 20.7 ton unmanned ATV maneuvered from a holding position 39km behind and 5km below the ISS, set up a direct link with the Station and conducted a 4 hour staged approach with several stops at reference points for checks. At a distance of 249m, the ATV computers autonomously computed its own position through RGPS (Relative Global Positioning System) data, comparing with GPS data received from ISS and in close range using VDM (Videometer) lasers pointed at LRRs (Laser Retroreflectors) on the SM for distance & orientation determination relative to its target. Final approach was at a relative velocity of 7cm\/s and with an accuracy of better than 10cm. The cargo transport, which remains docked for the next four months, is delivering 1,600kg of dry cargo, including food, clothes and equipment; 4534kg of ISS reboost\/attitude control propellants, 850kg of ISS refuel propellant to be transferred, and 100kg gaseous oxygen. Note: Prior to the start of closing maneuvers, ATV-CC (ATV-Control Center\/Toulouse) experienced a problem with one of its console tools which resulted in loss of ability to independently verify correct onboard boost computation, as required to monitor two Flight Rules (FRs). After discussion, these FRs were waived since the vehicle remained safe without these checks being performed, and in the knowledge that the NASA VVO (Visiting Vehicle Officer) console tools can perform a similar check to provide a level of confidence in the onboard boost computations. Later, the Russian Simvol display in the SM failed while ATV was at the S3 station keeping point. TsUP-Moscow performed troubleshooting and recovered Simvol. This caused an approximately 15 minute delay in ATV leaving S3. As for the ATV itself: all systems performed flawlessly during the docking.]In preparation for the docking:FE-5 Paolo Nespoli powered down the amateur\/ham radio equipment in the SM to prevent RFI (Radio Frequency Interference) with the cargo ship [it was turned back on later in the day].Paolo also configured the SM STTS communications panel 2 for the docking, taking out the RSA-2 channel to prevent possible echo\/feedback.FE-6 Cady Coleman closed the shutters of the US Lab, Cupola and JPM (JEM Pressurized Module) to protect them against thruster effluents [reopened before sleep time].FE-2 Oleg Skripochka activated & verified proper operation of the Russian TEKh-15\/DAKON-M IZGIB (\"Bend\") experiment in the SM for taking structural dynamics data during the ATV-2 berthing [afterwards, Oleg downlinked the data to the ground and shut off DAKON. IZGIB has the objective to help update mathematical models of the ISS gravitation environment, using accelerometers of the Russian SBI Onboard Measurement System, the GIVUS high-accuracy angular rate vector gyrometer of the SUDN Motion Control & Navigation System and other accelerometers for unattended measurement of micro-accelerations at science hardware accommodation locations - (1) in operation of onboard equipment having rotating parts (gyrodynes, fans), (2) when establishing and keeping various ISS attitude modes, and (3) when performing crew egresses into space and physical exercises].Oleg also activated & tested the Ku-band video \"scheme\" for transferring & downlinking streaming video via the MPEG-2 (Moving Pictures Expert Group-2) encoder, after Paolo had activated the A31p laptop in the FGB for the video conversion to US NTSC format.FE-1 Alexander Kaleri & Paolo configured the PCE (Proximity Communications Equipment; Russian: MBRL) in the SM for the docking [involving the MBRL AFU (Antenna Feeder Unit) and ATV PU Hand Controller].Monitored the approach & docking.After the docking, Alexander disconnected & removed the ATV PU Hand Controller unit with its power cable, covered the ATV connectors and stowed PU in the FGB.ATV Reboost:Tomorrow morning at 10:33 AM GMT, a one-burn ISS test reboost with ATV-2 OCS (Orbit Correction System) thrusters will be conducted for a duration of 198 seconds and a delta-V of 0.5m\/s.

Simple RGB won't cut it, since any given RGB value corresponds to multiple blends of different wavelengths. Also, you can't just limit yourself to the visual spectrum, because Doppler will shift stuff outside of the visual spectrum into it. So you'd need to have spectral data for each pixel at multiple points in the visual, and then even more points in the UV and infrared ranges, and, depending on how much Doppler you want to do, possibly into the microwave\/radio and X-ray\/gamma-ray ranges. At that point you're looking at textures with possibly hundreds of bits per pixel. Yuck...\n\nWell - it's a raytracer that can show us how wormhole would look like to human eyes so limiting it to RGB or HSI values is enough. We cannot see in UV ir IR so ot is pointless to take those shifts into account and compute them.When using HSI color model you can shift hue (spectrum in fact) to boundaries of human perception and rest may be cut off. I'm not programmer so making workable algorithm will be difficult for me. Also I don't know basics of your raytracer how it models energy but I think simple routine below should be helpfull:1 Read basic, unmodified by gravity value of pixel in RGB mode2 Convert it to HSI model3 Apply shift (red or blue) depending on gravity vector and power4 Convert back to RGBAs I said I'm not programmer and this is only basic Idea but it maybe it will help you.

The two fireballs \u2013 which produced bright freckles on Jupiter that were visible through backyard telescopes \u2013 occurred on June 3, 2010, and August 20, 2010, respectively.A new paper that includes both pros and amateurs, led by Ricardo Hueso of the Universidad del Pa\u00eds Vasco, Bilbao, Spain, appears today in the Astrophysical Journal Letters. In the paper, astronomers estimate the object that caused the June 3 fireball was 8 to 13 meters (30 to 40 feet) in diameter. The object is comparable in size to the asteroid 2010 RF12 that flew by Earth on Wednesday, Sept. 8, and slightly larger than the asteroid 2008 TC3, which burned up above Sudan two years ago.An impact of this kind on Earth would not be expected to cause damage on the ground. The energy released by the June 3 fireball as it collided with Jupiter's atmosphere was five to 10 times less than the 1908 Tunguska event on Earth, which knocked over tens of millions of trees in a remote part of Russia. Analysis is continuing on the Aug. 20 fireball, but scientists said it was comparable to the June 3 object.\"Jupiter is a big gravitational vacuum cleaner,\" said Glenn Orton, a co-author on the paper and an astronomer at NASA's Jet Propulsion Laboratory, Pasadena, Calif. \"It is clear now that relatively small objects, remnants of the formation of the solar system 4.5 billion years ago, still hit Jupiter frequently. Scientists are trying to figure out just how frequently.\"Orton and colleagues said this kind of discovery couldn't have been made without amateur astronomers around the world, whose observations of Jupiter provide a near round-the-clock surveillance that would be impossible to do with the long lines of scientists waiting to use the large telescopes. Amateur astronomers, for example, were the first to see the dark spot that appeared on Jupiter in July 2009 as the result of an impact. Professional astronomers are still analyzing that impact.Anthony Wesley, an amateur astronomer from Murrumbateman, Australia, who was also the first to take a picture of that dark spot on Jupiter in July 2009, was the first to see the tiny flash on June 3. Amateur astronomers had their telescopes trained on Jupiter that day because they were in the middle of \"Jupiter season,\" when the planet is high in the sky and at its largest size, as seen by backyard telescopes.Wesley was visiting an amateur astronomer friend about 1,000 kilometers (600 miles) away in Broken Hill, and he set a digital video camera to record images from his telescope at about 60 frames per second. He was watching the live video on a computer screen at his friend's house when he saw a two-and-a-half-second-long flash of light near the limb of the planet.\"It was clear to me straight away it had to be an event on Jupiter,\" he said. \"I'm used to seeing other momentary flashes in the camera from cosmic ray impacts, but this was different. Cosmic ray strikes last only for one frame of video, whereas this flash gradually brightened and then faded over 133 frames.\"Wesley sent a message out on his e-mail list of amateur and professional astronomers, which included Orton. After receiving Wesley's e-mail, Christopher Go of Cebu, Philippines -- who like Wesley, is an amateur astronomer -- checked his own recordings and confirmed that he had seen a flash, too.Before Wesley's work, scientists didn't know these small-size impacts could be observed, Hueso explained. \"The discovery of optical flashes produced by objects of this size helps scientists understand how many of these objects are out there and the role they played in the formation of our solar system,\" Hueso said.For three days afterward, Hueso and colleagues looked for signs of the impact in high-resolution images from larger telescopes: NASA's Hubble Space Telescope, Gemini Observatory telescopes in Hawaii and Chile, the Keck telescope in Hawaii, the NASA Infrared Telescope Facility in Hawaii and the European Southern Observatory's Very Large Telescope in Chile. Scientists analyzed the images for thermal disruptions and chemical signatures seen in previous images of Jupiter impacts. In this case, they saw no signs of debris, which allowed them to limit the size of the impactor.Based on all these images, and particularly those obtained by Wesley and Go, the astronomers were able to confirm the flash came from some kind of object \u2013 probably a small comet or asteroid \u2013 that burned up in Jupiter's atmosphere. The impactor likely had a mass of about 500 to 2,000 metric tons (1 million to 4 million pounds), probably about 100,000 times less massive than the object in July 2009.Calculations also estimated this June 3 impact released about 1 to 4 quadrillion joules (300 million to 1 billion watt-hours) of energy. The second fireball, on Aug. 20, was detected by the amateur Japanese astronomer Masayuki Tachikawa and later confirmed by Aoki Kazuo and Masayuki Ishimaru. It flashed for about 1.5 seconds. The Keck telescope, observing less than a day later, also found no subsequent debris remnants. Scientists are still analyzing this second flash.Although collisions of this size had never before been detected on Jupiter, some previous models predicted around one collision of this kind a year. Another predicted up to 100 such collisions. Scientists now believe the frequency must be closer to the high end of the scale.\"It is interesting to note that whereas Earth gets smacked by a 10-meter-sized object about every 10 years on average, it looks as though Jupiter gets hit with the same-sized object a few times each month,\" said Don Yeomans, manager of the Near-Earth Object Program Office at JPL, who was not involved in the paper. \"The Jupiter impact rate is still being refined and studies like this one help to do just that.\"", "thread_id": 16187 }, { "@timestamp": "2023-09-14T07:13:02.29785984Z", "author": "craigh", "date": "2010-04-19T22:53:00+0100", "id": "3d1221f5e7b235fe1c080101197c6e2a", "post_id": "post-218049", "text": "I started toying with one in AutoCAD and ran into problems.The first one being that there aren't many reference images, I also have a couple of the books printed for the movie.

[OBT objectives: Practice crew actions in the event of an off-nominal situation while monitoring rendezvous and docking, refresh rendezvous and docking monitoring skills, and practice crew interaction during rendezvous and docking monitoring.]Launch of ATV Johannes Kepler:Last evening (16\/02), at Europe's Spaceport in Kourou, French Guiana an Ariane 5 launch vehicle carrying \"Johannes Kepler\", ESA's second ATV (Automated Transfer Vehicle), lifted off flawlessly at 9:50 PM GMT (6:50 PM local). About 64 minutes into flight, ATV-2 separated safely from the spent upper stage and then deployed its four solar wings, beginning early orbit operations for its climb to the ISS, adjusting its orbit with numerous thruster burns to rendezvous with the station for docking on Thursday, 24\/02 (3:46 PM GMT). Weighing about 20 tons at launch, the unmanned supply ship will deliver critical supplies to the ISS (1600 kg dry cargo, 100 kg oxygen & 850 kg ISS refuel propellants propellant, plus 4534 kg propellant for reboost & attitude control). It will also reboost the station during its almost four-month mission. This launch marks the 200th flight of an Ariane vehicle since the debut of 24\/12\/1979. The total includes 11 flights of Ariane 1, 6 flights of Ariane 2, 11 flights of Ariane 3, 116 flights of Ariane 4 (from 1988 to 2003) and 56 flights of Ariane 5 (from 1996). Integration for the next ATV in line, named \"Edoardo Amaldi\", will be finished in Europe in August 2011, and production is under way for ATV-4 and -5. \"Edoardo Amaldi\" is planned for launch in about 12 months. The other two will follow by 2014. After \"Johannes Kepler's\" docking on 24\/02, ISS will for the first time have all logistics vehicles of the international partnership docked at the same time: the US Shuttle, one Russian Progress cargo ship, two Russian Soyuz spacecraft, Japan's HTV, and Europe's ATV, truly a moment of historic significance.", "thread_id": 13881 }, { "@timestamp": "2023-09-14T07:13:06.308315136Z", "author": "emin2004", "date": "2020-07-08T10:38:12+0100", "id": "37cb43f10a90bdb96ad5da169386e004", "post_id": "post-221611", "text": "forward to 2017 and your wish of the airless tire has been granted", "thread_id": 14112 }, { "@timestamp": "2023-09-14T07:13:34.901426944Z", "author": "Urwumpe", "date": "2010-08-23T00:57:53+0100", "id": "b22a3db3d36b74ccb40b8ebe85a05f6e", "post_id": "post-249833", "text": "Can it be you actually wanted to divide at this point?Code:[FONT=Courier New][FONT=Courier New]ctrl =([\/FONT][\/FONT][FONT=Courier New][COLOR=#0000ff][FONT=Courier New][COLOR=#0000ff][FONT=Courier New][COLOR=#0000ff]int[\/COLOR][\/FONT][\/COLOR][\/FONT][\/COLOR][\/FONT][FONT=Courier New][FONT=Courier New])(p.x*262.0f);[\/FONT]\n[\/FONT]EDIT:No... you need to multiply at this point, so the rest of the mess works.

Are they going to land it at sea or at land?\n\nTarget altitude 90 000 feet, water landing and recovery by boat. Azimuth and distance are more or less random, the spacecraft has no guidance systems and is being launched in the general \"up\" direction.The flight configuration being loaded now is a \"short stack\" with the crash test dummy strapped in to the Tycho Brahe spacecraft in its current form with the completed heat shield, glass dome and aerospike. The spacecraft is attached to its own parachute module beneath it, which is mated loosely (for in-flight retro-rocket assisted separation) to the nearly identical parachute module of the booster stack which consists of a half-length oxidizer and pressurization tank assembly(newly built - thanks gypsy scrap thieves you're really helping you know)on top of the modified booster which has 4 fins with rollerons. We'll have two downlink video streams and two-way data to both booster and spaceship.With the launch we're about to perform, we expect a quite low peak altitude for the spacecraft, with only about 15 seconds of active thrust. The goal is to test and validate engine performance, telemetry and radio systems, pyros, chutes, recovery and as many aspects of the whole thing as possible.If all goes well, the plan and hope is that by next summer we should be able to fly the long stack with a full-length and fully loaded oxidizer tank (with hydrogen peroxide instead of LOX) and some Scud- or V2-like graphite or carbon-carbon steerable baffles in the exhaust stream for active guidance, and a gas-powered RCS system in the Tycho Brahe parachute module.Tycho Brahe has been found to be too small to probably ever fly with real people. For one thing, the head of our poor crash test dummy can't fit in there with his helmet on. On top of the Heat-E1 which is the first plausibly man-rated booster in our schedule, we'll need to put a \u00f8800mm spacecraft instead of the current \u00f8640mm design. It'll still only support a nearly vertical crew posture but hopefully slightly less so. Everything we learn from flying Tycho Brahe will go into building the real man-rated spacecraft.\n\n", "thread_id": 16165 }, { "@timestamp": "2023-09-14T07:13:02.542967808Z", "author": "Goth", "date": "2010-04-22T12:11:14+0100", "id": "ad3f9ae5cd5f2c07ea62fb4d2f8da562", "post_id": "post-218522", "text": "jedidia said:I always thought it's the other way around...??\n\nAnd if so, gravity from what is caused?:)Gravity, at least as Einstein more or less said, exists because every object, with its mass, bends the space around itself, as when you put a ball into the sea: the water move to leave the space for the ball to enter it.

The findings are detailed in this week's issue of the journal Nature.Data from Voyager's low-energy charged particle instrument, first reported in December 2010, have indicated that the outward speed of the charged particles streaming from the sun has slowed to zero. The stagnation of this solar wind has continued through at least February 2011, marking a thick, previously unpredicted \"transition zone\" at the edge of our solar system.\"There is one time we are going to cross that frontier, and this is the first sign it is upon us,\" said Tom Krimigis, prinicipal investigator for Voyager's low-energy charged particle instrument and Cassini's magnetospheric imaging instrument, based at the Johns Hopkins University Applied Physics Laboratory in Laurel, Md.Krimigis and colleagues combined the new Voyager data with previously unpublished measurements from the ion and neutral camera on Cassini's magnetospheric imaging instrument. The Cassini instrument collects data on neutral atoms streaming into our solar system from the outside.The analysis indicates that the boundary between interstellar space and the bubble of charged particles the sun blows around itself is likely between 10 and 14 billion miles (16 to 23 kilometers) from the sun, with a best estimate of approximately 11 billion miles (18 billion kilometers). Since Voyager 1 is already nearly 11 billion miles (18 billion kilometers) out, it could cross into interstellar space at any time.\"These calculations show we're getting close, but how close? That's what we don't know, but Voyager 1 speeds outward a billion miles every three years, so we may not have long to wait,\" said Ed Stone, Voyager project scientist, based at the California Institute of Technology in Pasadena.Scientists intend to keep analyzing the Voyager 1 data, looking for confirmation. They will also be studying the Voyager 2 data, but Voyager 2 is not as close to the edge of the solar system as Voyager 1.

I tried two different things last night:Do the run to the moon manually again, this time taking care to record some stuff from the resulting windows crash dialog. See the contents of crash_1.zip (attached).Rename my orbiter folder to some backup name, and re-extract a clean install of Orbiter from the zip file. Then extract my IMFD5.4 zipfile into the new folder, and run the scenario again. It crashed again... see the contents of crash_2.zip (attached). Unfortunately I managed to not get the *appcompat.txt file this time around... hope it doesn't matter? If it does I'll just go back and get it.A strange thing I noticed, is that transX seems to be already installed on my \"clean\" install... I didn't think transX came with the default orbiter install?This raises the question: Do I maybe need to re-download it and start from there?So I used md5sum from GNU textutils (UnxUtils download) to determine whether or not my download had gotten interfered with somehow.Just for good measure, I did a checksum of my IMFD download too, as well as the .dll that got mentioned in the error report.ede8a82ab323d75ae90d58c7372a6a38 *orbiter100606.zip570400a133ffcbe39ff91af1e8616308 *IMFD54.zip8079998f9bb7246889c3fe3b15a8dbf8 *Cowell2.dllIf someone could please check their versions of these files against my md5's, the answer may jump out at us...Cheers,Johan", "thread_id": 16176 }, { "@timestamp": "2023-09-14T07:13:01.879671296Z", "author": "Urwumpe", "date": "2010-04-16T16:02:12+0100", "id": "2ccc45ad3349639c3250da2d6e06fc89", "post_id": "post-217801", "text": "I have the weekend for it, but I mostly have it full of development work for Orbiter, which sort of means I can't just play around as often as I want to, and often, my playing around ends in a new add-on getting done almost naturally.I would really like to have the time to kick off a small VSA for a la-grange space station project, but I don't see my time budget for orbiter changing anytime soon.", "thread_id": 13880 }, { "@timestamp": "2023-09-14T07:13:05.922039552Z", "author": "Auzar", "date": "2010-05-04T18:11:16+0100", "id": "ba640d1f0447fb39a21bf001b0aaebe2", "post_id": "post-221276", "text": "So, does it work?\u0422\u0430\u043a\u0438 \u0440\u0430\u0431\u043e\u0442\u0430\u0435\u0442 \u0438\u043b\u0438 \u043d\u0435\u0442?\n\nNo, does not work, 100504 does not work too, gives out the same error\u043d\u0435\u0442, \u043d\u0435 \u0440\u0430\u0431\u043e\u0442\u0430\u0435\u0442, 100504 \u043d\u0435 \u0440\u0430\u0431\u043e\u0442\u0430\u0435\u0442 \u0442\u043e\u0436\u0435, \u0432\u044b\u0434\u0430\u0435\u0442 \u0442\u0430\u043a\u0443\u044e \u0436\u0435 \u043e\u0448\u0438\u0431\u043a\u0443", "thread_id": 14091 }, { "@timestamp": "2023-09-14T07:13:35.351783936Z", "author": "Orbinaut Pete", "date": "2010-10-16T00:20:23+0100", "id": "9670204a403879dfeb572149405796ae", "post_id": "post-250412", "text": "Some NASA TV videos.NASA Experts Assist in Chilean Miners' Survival and Rescue.\u200bISS Offers Congratulations on Rescue of Chilean Miners.\u200b", "thread_id": 16193 }, { "@timestamp": "2023-09-14T07:13:01.92081664Z", "author": "C3PO", "date": "2011-02-24T16:09:39+0000", "id": "b709c4dd200bf49d065e05d5daf6099a", "post_id": "post-217923", "text": "We need a metric commentator for NASA TV :lol:r-dot was 0.07, not 0.5:)Why is the docking camera off-set from the docking target at the point of contact?

The launch vehicle will send the Kounotori2 H-II Transfer Vehicle (HTV2) into orbit on a week-long rendezvous with the station. \"Kounotori\" is the Japanese word for white stork, emblematic of delivering happiness and joy.On Jan. 27, Expedition 26 Flight Engineers Cady Coleman and Paolo Nespoli will command the station's robotic arm, Canadarm2, to reach out, grapple Kounotori2, and attach it to the Earth-facing port of the Harmony module.In the following days, a pallet loaded with spare station parts will be extracted from a slot in the cargo ship and attached to an experiment platform outside the Japanese Kibo module. Other cargo will be transferred internally to the station.The cargo vehicle will be filled with trash, detached from the station and sent to burn up in the Earth's atmosphere at the end of March.NASA Television's programming schedule for HTV2 events includes (all times CST):Thursday, Jan. 20:12 a.m. -- Launch coverage, anchored from NASA's Johnson Space Center in Houston, begins. Launch is scheduled at 12:29 a.m.Thursday, Jan. 27:5 a.m. -- Grapple coverage, anchored from Johnson, begins. The grapple of HTV2 is scheduled at 5:44 a.m.8 a.m. -- Berthing coverage, anchored from Johnson, begins. The attachment should be complete at approximately 10 a.m.For more information about Kounotori2 and the H-IIB launch vehicle, visit:www.jaxa.jp\/countdown\/h2bf2\/index_e.htmlFor more information about the International Space Station, visit:www.nasa.gov\/stationFor NASA TV downlink, schedule and streaming video information, visit:www.nasa.gov\/ntv", "thread_id": 16184 }, { "@timestamp": "2023-09-14T07:13:02.541087232Z", "author": "Fizyk", "date": "2010-04-20T21:34:53+0100", "id": "cb79949388e3d5543bd9be02788d9cd1", "post_id": "post-218506", "text": "Well, yeah, a wormhole is rather quite different from a black hole, though a Kerr black hole (a rotating one) can in a way act a bit like a wormhole.", "thread_id": 13925 }, { "@timestamp": "2023-09-14T07:13:35.557430272Z", "author": "Xantcha", "date": "2008-05-28T15:44:24+0100", "id": "f9b025fb4719a1891f490131a3a004a5", "post_id": "post-69010", "text": "Well, most of basic controls are on numpad.Personaly I never thought that advice to read manual is helpfull :^) Manuals tend to be hard to be references rather then tutorials.

I turned the antenna off, and voila, now time warp 1000x works as designed!The strange thing is that now I cannot reproduce the problem, even with the antenna on and tracking I can time warp 1000x without problems !?!Thanks a lot guys, your answers guided me in the direction of the solution.:cheers:cheers von Duus", "thread_id": 16186 }, { "@timestamp": "2023-09-14T07:13:06.091589376Z", "author": "Chipstone306", "date": "2007-11-18T13:47:58+0000", "id": "6ec84c6c38297f7ede035275258f0b4d", "post_id": "post-12287", "text": "I found this today ...Can we take this seriously:huh:http:\/\/www.space.com\/scienceastronomy\/time_theory_030806.html", "thread_id": 141 }, { "@timestamp": "2023-09-14T07:13:02.137171712Z", "author": "T.Neo", "date": "2010-04-19T19:46:30+0100", "id": "c653c86d454d41f290b05af3fea58dab", "post_id": "post-218010", "text": "Is there any study of how a manned Mars mission with surface visit could be done employing only EELV class launch vehicles?\n\nThere are several.

Because the the Orion-superlite would be unmanned at launch there will be no need for a man rated Atlas V, for that launch atleast.The Atlas V has the serious potential for being just such a medium class, economy-of-scale example. At this point we have ULA saying they want to man rate and make it avalible for multiple manned craft. If we had Orion-superlites, Dream Chasers and all the other NASA and DoD payloads flying I think it would reduce the cost of any indavidual launch significantly.It's kind of funny though because we want competition in launch providers to reduce costs but on the other hand if everyone is using the same launcher you get reduced costs as well.

This is my favorite addon bar none and it would be fantastic to get the LRV working. That scenario does indeed CTD for me. My Orbiter log is below. In the other scenarios, everything works flawlessly until the very instant that deployment and movement of the LRV is completed. At that exact point it crashes.\n\nHi Mantis,Please follow the judicious advise of tblaxland and deactivate all the plugin modules, except OrbiterSound. This will eliminate a lot of potential reasons for the crash.I would like you also try the \"post-deployment\" scenario published in my previous message (copy the contain of the window into your notepad and save it into \"Orbiter\\scenario\" as \"LRV-test.scn\" file and run this scenario). The precise point you described, where you get the CTD, correspond to the creation of the LRV vessel itself (just after the LRV turn on itself). This is why I suspect the problem belong to LRV vessel and probably not to the LRV deployment itself (which is are multiple and complex animations of a folded LRV mesh which belong to the LM vessel).If the included scenario crash, it will confirm that the problem belong only to the LRV vessel module and as nothing to do with LM vessel module. But if you can run this scenario and use the LRV, I will know that the CTD is linked with this very particular situation: The LRV vessel creation just after deployment.To know this information will allow me to prepare some furhter \"debug materials\" I will publish here, so you can test.ACS", "thread_id": 16191 }, { "@timestamp": "2023-09-14T07:13:06.774789376Z", "author": "Urwumpe", "date": "2010-05-09T18:18:55+0100", "id": "5294cb20c42c5abb094f0594d6d9b32c", "post_id": "post-222221", "text": "markl316 said:IIRC, orbiter 2005 had a sun glare effect.

I thought that we use the assumption that M >> m, where the mass of the planet is neglectable compared to the mass of the sun. If you want to analyse the more general case where two bodies are orbiting each other then the standard gravitational parameter would indeed be G(M+m). So I would say finally we have two cases here. The second case is more precise but also more complicated and it's up to you if you want to follow that road:1. M >> m (m neglectable):e = - G M \/ 2aE = - G m M \/ 2a2. m not neglectable:e = - G (M+m) \/ 2aE = - G m (M+m) \/ 2awith e, E the specific and total orbital energy of the orbiting body respectively.Now to the other question: Is the law of conservation of energy still valid (where did all the potential energy go?):)Let's assume we have the first case here and that M >> m and the mass of the star at the beginning is M+dm. So the potential energy of the planet at a distance r from the center of the sun would be:U1 = - G (M+dm) m \/ rAfter the sun has ejected the mass dm to outer space the potential energy of the planet is:U2 = - G M m \/ rPlease note that U2 > U1, so the planet is actually gaining not losing energy!And the difference in energy is:dE = U2 - U1 = [- (G M m) + (G (M+dm) m)] \/ r = (-G M m + G M m + G m dm) \/ r = G m dm \/ rThis is exactly the potential energy of dm with distance r relative to the planet. Or in other words exactly the energy that the ejected mass dm needs to overcome the gravitational field of the planet.

The \"solutions\" you listed deal with those long interplanetary distances, but not with the problem of playability of real-time space-travel.This is why:Even LEO operations take a long time to fulfill in real-time if we talk about current (and near-future) technology. If we are not talking about these, we can fast forward to FTL just as well, where no time compression is needed. But this is not the point of Orbiter, if I'm not mistaken.You could come up with a draft for using persistent worlds to cope with space missions lasting some weeks. E.g. start your shuttle, set trajectory for ISS rendevous, log off, go sleep\/eat\/school\/whatever, log on, final rendevous with ISS. This sounds all nice and such, but you have to time your real-life with simulation in order to log on at important points in simulation-time. There are some hard-core fans here that might do that, but not too many to justify a dedicated system running in that work-mode. In addition, scheduling round-the-world multiplayer-meetings is hard enough for one event, think about scheduling a whole mission with commanders, pilots and mission specialists.Time-compression in Orbiter is part of the usual \"play-flow\" of doing missions. I bet you are using it sometimes during ascent, too, if not restricted by the addon-vessel you're using. If only for 10x... Have you ever tried a real-time mission? Maybe only Redstones? There is really a different \"feeling\" to it, and - to be honest - a really boring feeling. And being boring is something a multiplayer system should avoid. Trust me, I know what I'm talking about.So to conclude my opinion: if you do multiplayer, you better do it with time-compression in mind.regards,Face", "thread_id": 16175 }, { "@timestamp": "2023-09-14T07:13:06.85069568Z", "author": "mrspacely", "date": "2008-05-12T09:04:31+0100", "id": "8875858c1c3de86937d3f8145897923d", "post_id": "post-65291", "text": "what can you do with orbiter? what can't you do?", "thread_id": 1417 }, { "@timestamp": "2023-09-14T07:13:06.662165504Z", "author": "tl8", "date": "2010-08-16T02:57:15+0100", "id": "934dda09b43955fa31c6f6939f5dbf1a", "post_id": "post-222151", "text": "Threads now mergedThe price is great.

On the other hand, it is my experience with programming that you often need to have done the programming before you get a good feel of the problem.So, for a good program you need a good design, and to make a good design you need to have made the program in the first place. So it often feels to me that, for complicated software, you don't escape from making it twice.

They represent some external resource that is being used by your program. Examples: user interface elements (such as windows), network connections, a handle for a sound API, or files you're reading or writing. You can obtain the resource in the constructor (open the network connection, create the window, open the file etc.), and release it in the destructor (close the network connection & so on). Examples of methods are methods for sending\/receiving network data, drawing things in the window, reading\/writing data from\/to files. The member variables contain handles for the external resources and additional data that is necessary for remembering the state of the resource.Data classes. They represent the 'virtual' objects of your software. For instance, for Orbiter this consists of things like spacecrafts, planets and MFDs.

Since the total mechanical energy of an ideal orbit is constant, this would appear to be a great way to determine velocities\/positions directly.I've run into two problems. First, when looking at kinetic energy, I notice that the velocity vector is replaced with the scalar velocity magnitude, removing any direction information from that vector. This is obviously a problem, as not knowing which way you're traveling means you can't propagate your orbit. Second, when dealing with potential energy, how does one deal with multiple sources of gravity? It's real easy when you're a block floating above a flat plate with only one gravity source, but it seems to get more complicated when you attempt to put said block around the Sun with the various planets acting on it.Are these issues resolvable?

Perhaps this could take the form of an 'armed' position of the speedbrakes?Continuing in the same theme, would an autobrake system be possible to include? In real life autobrake systems (the Boeing 737 at least!) there are several levels of autobrake that can be selected. The different levels represent an overall deceleration rate, for example if on landing the pilot chose to use reverse thrust, then the autobrake system would reduce the pressure being applied to the brakes to achieve the same deceleration rate as without the reverse thrust.I guess these are just my personal requests but I feel that if the XR1\/2\/5 were to be operated in real life then these systems would probably be included.Coming back to the \"if the XR1\/2\/5 were to be operated in real life\" way of thinking, I have also thought that some way of \"de-rating\" the engines for atmospheric flight could be a good idea when considering take off performance.In real life, aircraft takeoff performance is predicated on losing an engine. I realise it is not possible to easily simulate this within orbiter, but IF the worst did happen and you were to try and take off with 100% thrust operating on only one engine (I'm thinking XR2 specifically here) then it would not be possible to control the resulting yaw after leaving the ground due to the unbalanced thrust line. One simple way to reduce this would be to reduce the amount of thrust from the operating engine.Following the above idea, I don't know if V1 is a fixed value? Would it be possible for a dynamic value of V1 to be calculated based on runway length, weight etc?Also, I think you have spoken about this before but I would also make a request for an altitude hold and heading hold autopilot. I realise you want to keep the XR craft to be \"pilots aircraft\", but again thinking of real life operations, I don't think that these functions would detract from the experience. They would simply be used as a workload reduction tool, which is one of the reasons autopilots are used. Also, there is no requirement for anybody to use them! I just think that for those atmospheric flights (maybe delivery flights etc) it would make the process of fitting in with the existing air traffic routes an easier and safer prospect.Anyway, sorry that was such a long post, if you need me to explain any of my requests then give me a shout.

Even SPACE.com got it wrong.Voyager 2 will collaborate on Voyager 1's data as it arrives at interstellar space, predicted to be in afew years.Thisis relevant, informative, and interesting.Quick_Nick said:But HOW official is it?:p\n\nAnyways,NASA official.", "thread_id": 14169 }, { "@timestamp": "2023-09-14T07:13:34.9089984Z", "author": "LuckyHendrix", "date": "2010-08-29T09:28:26+0100", "id": "ffbff2761788bbae1c00d4f65a2b6fb0", "post_id": "post-249844", "text": "Another solution is to put both ship in prograde mode , docking ports will stay aligned.", "thread_id": 16170 }, { "@timestamp": "2023-09-14T07:13:06.525988352Z", "author": "statickid", "date": "2010-05-07T05:47:29+0100", "id": "08b7f412f84c214f293d7eb99a7b5d8a", "post_id": "post-221870", "text": "never had that problem, been using vista and orbiter a long time! oh... wait... i think i had that problem like 6 years ago and it was a problem having to do with user profiles. it turned out that i was not the \"administrator\" and the orbiter program would somehow launch only on the \"administrator\"'s profile desktop. whenever it did that i went and got my room mate and had him log into his profile, and there was orbiter, right on the desktop, running the whole time, just like the info box said.---------- Post added at 09:46 PM ---------- Previous post was at 09:43 PM ----------appended note: btw- i DID have full administrator priveledges, but for some reason it didnt matter. on my new computer i use vista and a user profile not named administrator and it doesn't make a lick of difference. i pretty much converted to windows after finding orbiter and discovering it can't run on other boxes. used to be a mac guy, now i own winbox almost entirely so i can use orbiter!! lolHAIL:probe:---------- Post added at 09:47 PM ---------- Previous post was at 09:46 PM ----------p.s.s.

This relocation is a preparation for arrival and docking of Discovery (STS-133), which is currently scheduled to launch on February 25. If the KOUNOTORI2 stayed in its current position, the Space Station Remote Manipulator System (SSRMS) will not be able to remove and transfer the payloads in Discovery's payload bay. The KOUNOTORI2 will be moved from the Common Berthing Mechanism (CBM) at the nadir port of Harmony to the zenith port of Harmony with the SSRMS manipulated by the ISS crew. After Discovery undocks from the ISS, the KOUNOTIORI2 will be returned to the Earth-facing port of Harmony.The KOUNOTORI2's relocation by the SSRMS will begin at 8:30 p.m. on February 18. The relocation is expected to be completed around 6:00 a.m. on February 19.", "thread_id": 16184 }, { "@timestamp": "2023-09-14T07:13:01.709622784Z", "author": "DaveS", "date": "2010-04-16T11:42:46+0100", "id": "bcd4893b3e0254c5246c73fdca2aa74f", "post_id": "post-217611", "text": "KosmoKen said:Never mind, I updated my NVidia drivers and everything's working just fine.

Its not the most simple format and it is probably not the best. Normally when writing a game you will define your own format and use the 3DS Max SDK (or other modelling package) to create your own exporter. However the .x format allows you to quickly get objects loaded. The advantages of using .x are that there are exporters for Max and other packages and DirectX has a number of helper functions for working with the loaded mesh data. Note that DirectX 10 and 11 do not contain support for .x files directly, instead they use a sdkmesh format that they provide functions for and a tool to convert from .x or .obj to.\n\nAnd since Orbiter 2010, it isn't only DirectX application, but it can be used with other graphics clients.But what's the problem with the .msh file format?

Given that f(2) = 3, what is f(3)?\n\nI solved this simply by integrating 2x and using the initial condition to find the function, then plugging 3 to get the answer 8.The class however did (f'(3)+f'(2))\/2+f(2) to get eight as well.The responder in the physics forum thread says that the statement in question is true for all quadratic. Is there a proof for that?", "thread_id": 14117 }, { "@timestamp": "2023-09-14T07:13:35.61288704Z", "author": "Skyfox42", "date": "2010-08-28T13:47:38+0100", "id": "12fe2a8c57d8528fde6d41f1a00d3051", "post_id": "post-251022", "text": "Hello everyone,My question is the following: To succeed an orbital plane change in 'Orbiter' one starts the burn at AN or DN and when stopping the burn the plane changing movement stops as well.In real life, why does the movement stop and does not need to be cancelled out by firing the thrusters in the opposite direction?Hope anyone can help me there.Thanks already a lot. :tiphat:Skyfox42", "thread_id": 16254 }, { "@timestamp": "2023-09-14T07:13:02.459305984Z", "author": "Fixerger", "date": "2010-04-23T22:50:25+0100", "id": "8a5fe9f16914d5850bc32755bf94138a", "post_id": "post-218346", "text": "Ghostrider said:Although it's speculation, I cannot fathom the logic of flying the Dragonfly to orbit manned. I see it as purely a construction device, it has limited life support and autonomy and it probably has no seats (you don't need them in freefall) or toilets or anything fancy. You just get in, start it up, close the hatch and go out for some hours until you've done your day's job, then you dock, take a shower and that's it. Sending it up manned would be madness.\n\nIMHO, I will choose Jupiter 120+Dragonfly+Orion. Orion performs all altitude and rendezvous management. It takes dragonfly to its destination then they all docking with target modules. Dragon performs all the work... then crew leaves it with station and comes back to Earth on Orion capsule.
