NASA Asks the Public For Advice On Goals

JeremyYoung writes: "The National Academy of Science's National Research Council is conducting what is being called the Solar System Exploration Survey at NASA's request. In it they are including public opinion from a web-based survey on the direction of NASA through 2013. The survey itself can be found at this page on the Planetary Society website. The article with more detail in explaining this is here. The survey closes on January 31, so don't miss this chance to tell NASA what you think it should be doing. pssst ... Mars can be done cheaply."

  1. instead of mars, by Stone+Rhino · · Score: 4, Insightful

    how about going to pluto? it would cost $600 million to send a probe, but the new nasa budget failed to include funding for that. If we don't launch a probe in 2006, we will have to wait 150 years for another opportunity. $600 million is nothing compared to the billions being tossed around on stuff like missile defense, so why not spend it and take advantage of this unique oppurtunity?

    Two good things about this survey. One, it used SSL to moderately obscure the data being sent in.
    Two, and most importantly, it was a form of multiple choice, with no space for free form answers. Had it been otherwise, the inundation of 'hax0r j00!' and 'go away alien fagz0rs' would have convinced them to start searching for intelligent life on Earth, first.

  9. Slightly Off Topic by JPawloski · · Score: 2, Interesting

    A while back I saw something on PBS where some guy from NASA showed a computer depiction of a space station which "created" gravity through centripetal motion. It seemed like a good idea because I know a lot of problems with space travel is the time limit due to atrophy of muscles from a zero gravity environment. The PBS guy dismissed this though by saying, "In fact, the US government knows little to nothing about making a station like this one."

    Personally, I think this should be the top priority. This would solve many of our problems and would allow a manned mission to Mars be possible. Why isn't NASA working towards this? What is prohibiting them from doing it? Or are they making progress that I am not aware?

      I think Arther C. Clarke was the first to 'theorise' on this.

      There's a problem with it though

      Anything in motion inside the space station will be subject to what is called "coriolis forces", which would not be experienced due to gravitational forces. The direction of the force is always perpendicular both to the axis of the space station, and the direction of motion. The faster the station rotates, the more the effect will be. So, one should try to make the station larger to minimize coriolis effects.

    I don't think it's worth it to send a man to mars just for the sake of having said we've sent a man to mars. Nasa should focus more on new propulsion and technology research. Fusion propultion would be great for interstellar travel. Hydrogen fusion converts about 1% of its mass into energy, so theoretically a highly efficient fusion drive could get up to a maximum of 1% of the speed of light. Alternatively, a propulsion system that uses solar panels to power a system that ejects ions at 99% of the speed of light, (and maybe uses a ramscoop) could hypothetically get up to a very high percentage of the speed of light, although it would take centuries. The good thing about this is that it is infinitely replenishable. Another possible propulsion system involves using antimatter as a fuel. This would allow achieving a decent fraction of the speed of light, and with good acceleration, but antimatter is extremely difficult to manufacture in large quantities, and will probably remain as such for a long time.

    1. Re:Priorities by Dancing+Tree · · Score: 3, Interesting

      I both agree and disagree with the author of said referenced comment. Indeed, I do believe that we should be concerned with getting to Mars (or Venus, or back to the moon, etc.) AND we should be developing not just new drives, but new ways of getting payloads off of the planet's surface. The amount of mass and energy wasted in launching craft/cargos into space is ridiculous right now. So how about some magnetic accellerator action at least for the non perishables (I understand it can generate quite alot of G's in acceleration. Maybe this can be modded) and maybe some slower but less wasteful manner for getting live loads at least into orbit.

      These questions weren't even asked on the survey though maybe NASA considers them as part and parcel of all the other options offered. Whatever the case, I do believe that it would be a great achievement for the human race and the planet, for us to venture out into wide and vasty space that is the rest of the universe. Who knows what mind blowing, cool stuff is out there for us to find.

    A little background on this survey might be in order. The survey is being run by the national academy of sciences, although most of the input (from the planetary science community) was gathered by the American Astronomical Society's Division for Planetary Science. The survey is a decadal one, meaning it'll be redone in 10 years. So if you have a strong hankering to go somewhere that can/should wait a decade, you'll get your chance to sound off in 10 years. Astrophysicists have been doing these decadal surveys for several decades now, and they've been very sucessful.

  13. The public has no say on the most important things by Spamalamadingdong · · Score: 5, Insightful
    Unfortunately, NASA is tied to established projects with established constituencies; without the lobbying of those interests, NASA does not get its budget. Moving money from today's cash cows to tomorrow's research projects is like pulling teeth, and this only seems to change when there is some issue of national prestige at stake (between 1957 and 1969, it was showing that we were better than the Russians on the stage of international grandstanding). Don't believe me? Consider the following:
    1. The established Saturn booster production line was scrapped to eliminate competition for the Space Shuttle and its lucrative R&D contracts.
    2. The various incarnations of the space station keep losing size, personnel and research capabilities, but the whole thing is never tossed out and re-done from scratch. Apparently it suits the entrenched interests more to have a white elephant in orbit sucking up every available dollar than to take the budget and see what can be accomplished with it. The effort to quash the Lawrence Livermore Labs "community space suit" space station is a case in point.
    3. The DC-1 project was on track to produce an SSTO launch vehicle which could fly far more frequently and cheaply than the Shuttle. Of course, it was developed by SDIO (it could never have been built at NASA). The established interests got it taken away from SDIO and handed over to NASA, which completed the test program and promptly crashed and destroyed the DC-X test vehicle.
    4. Rather than pursuing the development of the DC-Y using the results of the DC-X test program, NASA scratched it and instead decided to fund a completely new vehicle, the VentureStar (which promised a lot more development money). Of course, the VentureStar's future is now in doubt as its fuel tanks apparently cannot be built.
    Unless we the public can get behind some program which demands results instead of pork, we are going to be dumping more billions and tens of billions on projects which leave us little or even nothing to show for them; meanwhile, all the cutting-edge stuff like DC-Y and Deep Space One will be done on a shoestring if they can be done at all. Our future in space depends on shouldering the pigs away from the money trough and demanding results.

Various limitations on the types of organizations, to discourage cheating (and maybe also limit to US orgs only, to help this get around national security concerns)...but, once the specs are out, they do not change. Boeing and Lockheed can maybe pick off a couple of the prizes then scrap development of their projects like they have in the past, but smaller entrants (not affiliated in any way with any other winners of the same prize, or with the US government) would pick up the rest...and then, out of (say) 5 prizes, there would be 3 viable cheap-to-orbit lauunch vehicles out there, ready for public use.
