NASA Needs Prize Contest Ideas 180

Posted by michael from the grand-prize-is-one-way-trip-to-mars dept.
Michael Huang writes "If you like the idea of tech contests--think ANSARI X PRIZE and DARPA Grand Challenge--and you also like space, then NASA wants you. It needs ideas (and rules) for the Centennial Challenges, prize contests with $20 million funding in 2005.

    Artificial Intelligence. I mean robots, space missions, even just regular things are all cool, but Artificial intelligence would enhance them all. It would allow for more unmanned space flights, and lessen the amount of direct attention necessary for some given projects. Not to say that we are to rely on AI solely, but that it can be a great aide in what NASA is trying to do, and it would help other realms of science as well.

    • You should look at some of the robotics projects. For example, there is one contest (I think DARPA is sponsoring it) which IIRC requires robots to find their way through a course at high speed---autonomously. There's AI right there, although it isn't quite yet of the "not opening the pod bay doors" caliber.

    • Parent: +6 Insightful

      I'm a researcher in AI, and I can do nothing but backup the parent's claim (sad as it is). When we use AI, we would expect a robot to be able to perceive its surroundings (analyzing sensory inputs), make decisions (reasoning) and act (generating actuator outputs).

      I can only comment on the first, since I'm a Ph.D. student in Computer Vision. And the general picture is, to be quite honest, depressing. Forget all you've seen in e.g. Terminator (e.g. the robot analyzing its visual input, and all the nice text in the image): it ain't gonna happen for a long time! Although space missions are (presumably) less complex in terms of sensory inputs, the state of affairs in dealing with normal natural images gives a nice idea of what's currently (im)possible:

      I'll provide an example here. I'm doing Computer Vision (face-detections), and the current state of affairs is about this: When finding faces in 800x600 images, this can be done in about 1 second (yes: 1 full second), at about a 90% detection rate and a couple of false detections per image. For more complex object classes that are not so nicely symmetric (think cars, houses, landscapes, etc.), the performance is dramatically worse.

      You can look at the BitTorrent link [unimaas.nl]. And ONLY if that doesn't work, use this [unimaas.nl]. As for reasoning: this is still in it's infancy, but I'm not working in that field, so I cannot comment on that well. Any takers? ;)

      • As another person who has done research with AI and computer vision, I agree with you somewhat. We're nowhere near having an autonomous system with capabilities anywhere close to what a human, or even a very small insect, can perform.

        However, AIs in space only have to perform very specific tasks. These sorts of tasks are things which AIs are already capable of, or could be made capable of with a little more effort. Here's what I could think of off-hand:

        space navigation: This is the sort of thing an AI excels at. I think it's actually already been used on Deep Space 1 [cnn.com].

        surface exploration: If humans on the ground can periodically give high-level goals and destinations, the rest can be handled by a reactive or behavior-based system. After Sojourner [wikipedia.org]'s primary and secondary missions were over, it was switched over to a behavior-based control system (developed by Rodney Brooks' lab, I think), and autonomously wandered around the surface.

        space construction: This hasn't really been done yet, although many vision problems can be alleviated by the fact that you have complete control over the materials used. Special parts can be given special colors, and one might be able to assume that all prior pieces have been accurately placed by a robot.

        By the way, nice face detection work.
      • Bah! more details. I watched your face detection video and read the blurb on your web page, do you have a paper or tech report on it? I've seen another video from a research group here that looks almost identical to this one, kind of amusing.

        I've seen real time demos of Viola-Jones cascades that work reasonably well. And training time isn't so ridiculous if you cut out the adaboost feature selection. Your idea to pre-process input images (segment them) into interesting and non interesting regions seems

      The quickest way to make this happen is a one-way trip. I doubt NASA is going to fund an group to kill someone, no matter if the person is a volunteer who's willing to do it.

      [Now, there's other groups in the US government who might be willing to provide funds for killing people, I just don't think that NASA is the one, though]

      But let's think about it -- you'd probably have to find someone who's willing to make the one-way trip, but wouldn't be crazy enough to commit suicide on the trip there.

      Modern spacesuits are pretty dire; they're a bad compromise between a full constant-pressure hardsuit and a zero-volume skinsuit. This means that they tend to blow up when they're pressurised, which means they resist movement. This makes them very hard work to actually move around in. They're also very complicated.

      Constant-pressure hardsuits would be one alternative, but as they require complex joints for all the limbs you won't be exactly agile in one.

      A more interesting alternative is the skinsuit. This consists of a very close-fitting elastic body stocking that provides pressure on the skin to protect you from vacuum, while not actually containing any air. (The only hollow part is the rigid helmet.) These would --- probably --- be much more comfortable, restricting motion much less, probably be more reliable, certainly simpler to construct, etc. Although they might be rather hard to put on.

      Unfortunately, I can't find any references to skinsuits, although I gather they've been tried in prototype --- can anyone confirm this?

      • Yes skinsuits have been studied and prototyped. Jerry Pournelle wrote about them years ago in his "A Step Farther Out" column.
      • The problem with a skinsuit is that it will do absolutely nothing in the case of being struck by space debris. In order to overcome this particular issue you're going to have to put armor on it, and then you come back to the point where you might as well be wearing a hardsuit.

        What I think makes the most sense is a skinsuit worn under a hardsuit. This way, you're protected from impacts, but if your suit should get holed you're still protected. Seal the helmet away from the rest of the suit, of course, so t

        • Actually, considering the many thousands of KPH of impact speed, almost anything that actually hits you in space is going to do serious damage to you, hardsuit or not. However, a very loose lightweight aluminum-foil outer layer (like a rain poncho) will have an interesting effect; small space debris (like paint flakes or micrometeoroids) that impact against this "poncho" will be vaporized, making a tiny hole in it -- and the skinsuit will very likely protect you adequately from the spray of fast-moving gas
          • It does sound like a good idea though I think it might prove to be too fragile and/or bulky. The hardsuit should be layers of composites and possibly some sort of non-solid stuff, a liquid [slashdot.org] or a gel perhaps. Now that you mention it, putting a pressurized gas behind that might be a nice way to make it more reactive. If you could make it seal the hardsuit in the bargain it would be really amazingly slick. Using composites keeps the total mass to a minimum while still giving you a rigid shell. If someone swung

    Well, what NASA needs more than anything, is low cost access to orbit. That is what the X-prize is about, but NASA could probably get more bang for their buck by having a prize for a high specific impulse rocket engine which can operate in atmosphere. Simply set a minimum thrust, maximum weight, and minimum specific impulse, and see what people come up with. Ion and plasma engines have Isp of 10,000 or higher, but can't run in atmosphere (and require power supplies). If the space shuttle had that high of an Isp, it would need a ton or two of fuel (just guessing, don't feel like doing the math at the moment).

    Of course, who knows how someone would find a way to make an engine like that. However if it is something with a low cost of entry (unlike the X-prize) which every backyard inventor can work on, then you instantly have a few thousand amateur rocket scientists working for a prize of a few hundred thousand. A pretty good deal, I say.

    If you're going to award monetary prizes, why not get serious.

    Jerry Pournelle was suggested the following:

    I can solve the space access problem with a few sentences.

    Be it enacted by the Congress of the United States:

    The Treasurer of the United States is directed to pay to the first American owned company (if corporate at least 60% of the shares must be held by American citizens) the following sums for the following accomplishments. No monies shall be paid until the goals specified are accomplished and certified by suitable experts from the National Science Foundation or the National Academy of Science:

    1. The sum of $2 billion to be paid for construction of 3 operational spacecraft which have achieved low earth orbit, returned to earth, and flown to orbit again three times in a period of three weeks.

    2. The sum of $5 billion to be paid for construction and maintenance of a space station which has been continuously in orbit with at least 5 Americans aboard for a period of not less than three years and one day. The crew need not be the same persons for the entire time, but at no time shall the station be unoccupied.

    3. The sum of $12 billion to be paid for construction and maintenance of a Lunar base in which no fewer than 31 Americans have continuously resided for a period of not less than four years and one day.

    4. The sum of $10 billion to be paid for construction and maintenance of a solar power satellite system which delivers at least 800 megaWatts of electric power to a receiving station or stations in the United States for a period of at least two years and one day.

    5. The payments made shall be exempt from all US taxes.

    That would do it. Not one cent to be paid until the goals are accomplished. Not a bit of risk, and if it can't be done for those sums, well, no harm done to the treasury.

    Henry Vanderbilt points out that having a prize, say $1 billion, for the second firm to achieve point (1) above will get more into the competition, and produce better results. I agree.

    These challenges are not the same as X-Prize, as they have shifted from ones directly competing with NASA (e.g. independent, private launch capabilities) towards ones more complimentary to NASA (e.g. better Astronaut gloves, robotic insects).

    If the US Government wants to encourage more independent space resarch, the Congress and President must work together to establish goals INDEPENDENT of NASA. One possibility is to simply have the Congress double the prize money for the next few X-Prizes once those details are finalized.

    NASA will NOT spend its money to pay for the development of a competing private space industry.

    Easy contest to define, but maybe not so easy to win. Just specify the material properties needed for a practical space elevator, and offer a sizeable prize to the first group to present a sample of a certain size.

    Also, you could offer annual prizes for the best results each year, even if they don't meet the final prize criteria. At least that'd give the research groups a short-term goal to reach for.

    What about an electromagnetic assisted launch? I remember from my astro engineering class that a very significant percentage of any launch vehicles fuel is required to just get it to clear the tower. Why not build a scale model launch vehicle and tower that is capable of attaining a certian altitude using EM assisted launch. Make one of the requirements that you use 20% less fuel than a non-EM assisted launch. We already have maglev trains that go 300 MPH and roller coasters driven by linear induction motors, so it doesn't seem like it would be too hard to adapt these technologies to space launch.

      This was my intention when (above) I mentioned railgun launches. Since most of the mass we want in orbit is (at present) consumables and other commodity products, this would do fine for EM launches.

      A competition featuring the best railgun designs (open to all university engineering students especially) would stimulate development of this area. I am convinced the military has versions of this they are not mentioning, but the civilian world should have some capabilities here too.

      This is a fairly simple project to build for an engineering department, and would combine the disciplines of mechanical, power, and computer engineering departments to get things right. Further, if groups of engineers in a city wanted to build such a device, this would be a possible thing to try.

      A note about manned launches using EM / railgun / mass driver technologies. In physics class in high school we worked out that it was nearly impossible to build a railgun / EM launch vehicle that would achieve orbital velocity and carry a manned payload. The G-force limit of 12 G's prohibits acceleration to mach 25+ in a reasonable ground distance (it's way too long geographically to build).
      MATH:

      Escape velocity (Earth) = 11000 m/s (about mach 25 or 19,000 mph)
      1 G acceleration = 10 m/s/s
      = 1100 seconds @ 1 g
      = 110 seconds @ 10 g's
      = 11 seconds @ 100 g's
      = 5 seconds @ 500 g's

      This competition would be easy to run (at some gunnery range, out over an ocean, etc.). Military radar could track the payloads. Bonus points could include if the payloads were recoverable, and more bonus points if the payloads contained inert liquids that would simulate liquid O2 in density.

        Except that railgun design isn't really the show stopper. Developing a TPS to protect the payload from the effects of atmospheric heating *is* however a showstopper.

        Even if the exit of the railgun was on top of Mt Everest, you are still deep within the sensible atmosphere, and miles and miles below where boosters normally add their speed. (Boosters normally go more-or-less straight up, then bend their trajectories over to add the horizontal velocity needed to reach orbit.) Given the amount of atmosphere you have to traverse after leaving the railgun, you need to leave it at much higher than orbital speed, to offset for drag, that you have a truly frightful thermal problem.

        Another issue often handwaved away by EM launcher supporters is the need for a propulsion system for the circularization burn. Lunar surface-Lx railguns don't need these systems because they are not going into orbit around the launching body. Earth-to-orbit systems however do and generally end up being around half the total throweight at the launch systems muzzle. (Just having a projectile traveling at orbital velocity is meaningless. The *direction* of the velocity vector is all important, and EM launchers cannot produce the proper vector.)

        The final problem is the extreme G factor typical of EM launches. This causes structural weight to dominate total throweight, to the great detriment of payload fraction and total payload throughtput of the launcher. (In theory the structure can be recovered as raw material at the target, but in practice you end up with more raw material than you can use.)

        . I am convinced the military has versions of this they are not mentioning,
        Why would you be so convinced? EM launchers are simply not practical in the near term, and are likely to remain so indefinetly to Earth-to-Orbit operations. There are simply too many practical problems.

    To kickoff Centennial Challenges, NASA's new program of prize contests, NASA will host a workshop on June 15-16 in Washington, DC. The purpose of the workshop is to:

    1. Gather ideas for Challenges,
    2. Develop rules for specific Challenges and gauge competitor interest in various potential Challenges, and
    3. Promote competitor teaming.

    This workshop will be a key input into Centennial Challenges planning, helping to determine what specific Challenge competitions NASA announces in 2004 and 2005 and the rules of those competitions. All potential Centennial Challenge competitors, including interested members of industry, academia, students, and the general public, are invited to attend.
