NASA Exploring 8 New Space Expeditions 106

Posted by samzenpus from the a-whole-lot-of-exploring-going-on dept.
coondoggie writes "NASA is trying to decide among eight space exploration missions that include further exploring Venus and comet composition as well landing on an asteroid or examining the space around Jupiter. The space agency today began accepting solicitations for these space exploration opportunities and will ultimately pick one of them to begin perusing in 2009 with a launch date targeted at 2018. The solicitations and ultimate expedition are part of NASA's New Frontiers program, which has as its main objective to explore the solar system with medium-class spacecraft missions that will conduct high-quality, focused scientific investigations, NASA said. The first New Frontiers mission was selected in 2003 and will result in the launch of Juno, a Jupiter polar orbiter mission set to blast off in 2011."

      Detroit already did come up with a good electric car [wikipedia.org]. But, in a typically brilliant move for GM, they decided to cancel the program when it was still in the lease-only stage, revoked all the leases, refused to sell the leased cars to the many people who actually wanted to buy one, sent every one of the cars into a scrapyard compactor, and promptly canceled all further electric/hybrid development plans to focus on SUV's. This stunning lack of forward-thinking is just one of the many reasons why GM is in Washington today begging for a handout while smarter companies like Toyota are taking over the auto industry.

      • Fortunately for them their development efforts did yield a number of patents which they can exploit for profits when somebody else produces the electric car, without further effort or investment on their part.

        This is why patents are evil. They prevent progress.

    • The 'eliminate world hunger' or 'find cure for cancer' crowd still has priority over these random funds but I wouldn't mind killing off the human exploration project and using its budget to fund all of these missions (and use the remaining 50% for astronomy, e.g searching for Earth-like planets or Near Earth Asteroids).

      • Part of the wonderful things about research and exploration is that it pays off fabulously, in unpredictable ways. We cannot be sure that the answers to the "eliminate hunger" and "cure cancer" questions are not to be found on the road to Mars. They might in fact be found in no other way.

    And seriously harden up the electronics. If the Pioneer and Voyager probes can do 30+ years, a modern probe can. Given the fuel efficiency of the ion drive, a probe could also carry enough fuel to perform a great many missions. It may not be able to do everything on the list, but a decent design should be able to tick off a fair few at less cost than one probe for each one.

    I want to see balloons dropped into the atmosphere of planets. Particularly giant planets. Best pick would probably be Saturn, but I'm sure we could learn interesting about Uranus if we sent a balloon there. And Neptune too, although I'm afraid the winds are a bit too violent there. Jupiter would also be great but I'm afraid the superior "surface" gravity there would make it harder.

    I wonder if you could also do that on Venus (too hot maybe?) or Titan.

    Oh and to clarify my idea : the balloons/blimps would stay aloft for months on end, going up and down in the atmosphere on command to study different altitudes, drifting off the winds, telling us more about them, performing all the analyses possible, and not just about the atmosphere but also (why not) the magnetic field and whatever else might be interesting. And of course a good colour camera, so we can see what it looks like from there, see the clouds, thunderstorms, the moons through the coloured atmosphere, boreal auroras, and so on.. That would be pretty exciting.

      Correct me if I'm wrong but I thought the idea of that would be hard to accomplish in the first place. Your talking about something like a weather balloon correct? I was watching some science channel show where they were talking about that idea, but it would be hard because a large portion of Saturn or Jupiter is made up of hydrogen and helium gas, and to get a gas lighter than that is kind hard.

      Unless you were to heat hydrogen or helium in order to make it lighter than the hydrogen or helium that is currently in the atmosphere. Other than that you would have to create a new element that had an atomic mass smaller than hydrogen which I'm not sure if it is possible to even do. Atomic mass of 0 would be an interesting element for sure.

      Then again I could be wrong, and if so let me know because that would be interesting.

        Good point. I don't know, maybe you can make a transparent blimp with a greenhouse effect that warms the inside of it? Considered how cold these atmospheres are it would maybe be a trivial problem, I don't know.

        As for an "atomic mass of 0" well it's called vacuum. However we don't use it in blimps because in order to keep a balloon "filled with vacuum" inflated, you need something pretty damn rigid, which most of the time (I think) means too heavy. I'm far too unqualified to "call" any of these ideas, i.e.

          Not enough solar energy to warm a blimp that way, but radioactive heat sources do nicely, and yes people have studied hot hydrogen balloons / blimps on Jupiter, Saturn, etc. They seem to work ok, if you stay out of the regions with high wind shear (flying a blimp into a hurricane is a bad life path choice...)

        Hmmmm... an atomic mass smaller than hydrogen, possibly an atomic mass of zero. What, just what I say, has an atomic mass of zero!?

        Why, nothing!

        How about we make a weather balloon filled with nothing?

        • Well I don't know if it would float in the atmosphere then. I'd guess that to contain a vacuum and keep the balloon filled you would need to have it quite strong. And to do that it would add weight. Which would in turn require a larger balloon structure. Then that would require a larger vacuum and so on. I think it would get to a point where it would become too large to even attempt.

      50-60km up, the atmosphere of Venus is roughly at Earth-normal temperature and pressure. Bog standard air is a lifting gas there too, being less dense.

    • I wonder if you could also do that on Venus (too hot maybe?)

      No need to wonder, it has been done: http://www.mentallandscape.com/V_Vega.htm [mentallandscape.com]. The aerostats (that's the collective term for all lighter-than-air vessels) were part of the same payload as landers for increased difficulty, too.

      Some quotes from the link:

      The aerostats were deployed at the anti-solar point of Venus, above the continent of Aphrodite Terra. During 46 hours of operation, they traveled about 1/3 of the way around the planet in the 240 km/hour zonal winds.

      After the end of signal, the balloons probably overheated and burst, somewhere on the daylight side of Venus.

      So there is a first generation. Many are ignorant of this and the rest of the Venera program (linked site is recommended). This ignorance has probably been "helped" by Soviet scientific successes not being considered the hottest stuff to tell people about.

    Should be relatively cheap and reliable hardware. While the surface is the definition of a hellish landscape, the cloud tops of Venus are the only place in the solar system (other than Earth of course) with temperatures and pressures that humans could survive in. Not only is that interesting from a human habitation standpoint, but the mild conditions should also improve the lifespan of the balloon probe itself.
