NASA, European Space Agency Want To Go To Mars

coondoggie writes "NASA and the European Space Agency (ESA) are aiming to cooperate on all manner of robotic orbiters, landers and exploration devices for a future trip to Mars. Specifically, NASA and ESA recently agreed to consider the establishment of a new joint initiative to define and implement their scientific, programmatic, and technological goals for the exploration of Mars. The program would focus on several launch opportunities with landers and orbiters conducting astrobiological, geological, geophysical, climatological, and other high-priority investigations and aiming at returning samples from Mars in the mid-2020s."

What happens when that's not true? What's the point of gathering tremendous information about the Solar System, if nobody is going to be using it aside from a few scientists? Second, science in space costs about one to three orders of magnitude more than equivalent science on Earth. We could be doing a lot more science merely by redirecting space science funding into more mundane things on Earth.

      My take is that the reason the US and EU should be involved, is because this will be the next big human expansion after discovery and development of the New World (1492-present) and the conversion of the entire world to high tech societies (1900-present). They'll be in a position to figure good approaches for colonization and resource utilization. They already have a good idea what is out there. If there are American and European businesses making money in space or people living in colonies on another world, then there's a need for space science beyond just satisfying someone's idle curiosity or feeding a starving graduate student.

      Color TV predates NASA by a few years (1950 or so compared to 1958 being the start of NASA). My view is that spinoffs from current space programs are greatly exaggerated in a fashion similar to space science. This leads to a similar argument against funding space-related spinoffs (especially human space flight related spinoffs). Namely, that you can spend a lot less in more focused R&D to generate comparable spinoffs and science. In other words, if spinoffs and science, publicly funded, are your thing, then there are more effective ways to do it.

    Actually, I wonder the same thing with actual gold sales where you don't physically receive the product. How do you know it isn't some dude with a phone center and a good printer?

    Realistically, you could pull off such a scam by simply issuing gold notes. Lets say that the price of gold is $1000/ounce.

    You collect $100000 from some guy and issue him a certificate stating that he has purchased 100 ounces from you which are his to collect within maturity of this note (or whatever language you want to include)

    Now, you have $100,000 to work with. If Mr. Gold Buyer waits 10 years and wants to cash out his gold, all you have to do is outperform the gold market with that $100,000. You keep (or lose) the difference (ignoring taxes for simplicity)

    There really isn't anything magical about the market... and come to think of it, why did I call that a scam? It's roughly what is going on in today's market with those notes. That's how most things are traded.

    Diamonds are only that valuable because of the De Beers monopoly. Still at highest quality diamonds, assuming with just a whiff of delusion that these diamonds could be sold for $80k per gram no matter what, then sure, you could probably make a profit. $80 million per kg is a pretty good price for payload.

    Well, you can conceivably build things in zero G. The question would be whether it's easier to build things in zero G or where there's a bit of gravity. Gravity has some advantages: Drop something and it will hit the ground, rather than floating away. While building stuff in zero G looks way cool, I'm more interested in efficiency.

    The problem with getting stuff from Earth is that it's at the bottom of a really deep gravity well, which limits how much stuff we can get out of it. So shipping water and building materials up to Earth orbit is expensive. Remember that, for x amount of fuel, you can ship 6X the weight from the Moon than you could from Earth.

    The problem with getting stuff from Asteroids is political: you have the "what if something goes wrong?" crowd. "Let me get this straight--you want to go find an asteroid and send it toward the Earth?! What happens if you can't control it?! What happens if something goes wrong and it crashes into the Earth?!? Won't somebody think of the children?!?!"

    You could mine it and process it on the asteroid and then ship it to Earth orbit for assembly. But we're back to the gravity issues: Mining and processing in negligible G (eg Ceres, the largest asteroid, is 0.03G) will have it own issues as well. On the moon, we have to deal with dust--imagine how much dust mining an asteroid will generate? This a problem we have to solve anyway, whether it's on the Moon or an asteroid.

    As for water, I may be wrong but space is not only pretty darn cold, it's pretty darn hot. The ISS temperatures range from -250 F to +250 F, depending on whether it's in direct sunlight. So I would think water would melt. But I may be wrong.

    Plus - most applicable objects in the solar system are probably piles of rubble, with gravity just enough to hold them together. Which presents its own kinds of problems if you want to move them or make any contruction work with them.

    As for water - yeah, comets are a good example of what would happen to exposed water ice in close solar orbits, though I imagine you can use thin external shields to limit exposure to sunlight or perhaps turning water into http://en.wikipedia.org/wiki/Pykrete (lunar dust could work great for this?) But water has another problem - it's hard to build lightweight structures with it, limiting it's potential usage mostly to small radiation shelters on ships and...stationary bases not meant to be moved / launched. Like on the moon.

    So...I take it it's even more plausible in the case of US space program, given that it actually lost much larger number of flight personnel?
