I think putting a man on Mars is a stunt. And putting men there, one way, is just as stupid as anything else I've ever heard. You can't colonize Mars before you terraform it. Because you can't terraform Mars after you colonize it. And of course, that they would survive a year is among the rosiest of assumptions. A better idea would be to send a preparatory robotic mission to Phobos. Specifically, to that spot on Phobos directly facing Mars. Phobos is tidal locked. The moon does not turn in relation to the planet, just like the Moon. (capitalized, Moon refers to THE Moon.) This means the moons bulk shields the site from almost half the sphere while the planet shields it from almost the other half of the sphere. This means this spot has the lowest cosmic radiation intensity for any spot in the solar system that is outside atmosphere and magnetosphere. Mars has precious little magnetic field, so for 99% of the planet, Phobos is radiographically better. Build a wall around the site, and people could stay there for years without radiation problems. But the escape velocity is bicycle speed. So people couldn't stay there for years without gravity problems. Mining equipment could stay for centuries, though, without radiation problems. The stuff would stay right where it was put, too. That is kinda handy, when you are 30-60,000,000 miles away. You'll know where your gear is. When you want to use the equipment, launch is easy. 25 mph is all it takes. The kicker is. Phobos is an asteroid. I think of it as 'Asteroid #1'. So asteroid miners can mine it. 25 mph escape velocity is also all it takes to capture almost all of the rubble mining will cause Which is handy, because they pretty much HAVE to set up a base to do it. And that is where the base SHOULD be put. The folks thinking about asteroid mining now want to do it in low Earth orbit, because they get free radiation shielding. Trouble is, their rubble would make manned spaceflight way too dangerous, so I don't know what they think they are gaining. Another thing I don't know is why they think they need astronauts to mine asteroids. Are they visualizing Buzz Aldrin shoveling Moon rocks into a sample bag? That is not mining. At best, it is prospecting. Let them go to it in LEO, though, and the rest of us are FUCKED. Low Earth Orbit will quickly be filled with little rocks buzzing every direction at 17,000mph. Goodbye ISS, GPS and anything else nearby. The complaint that Mars is far is bunk. Robots don't get bored on long flights and the energy to return is the same as from the Moon. In the case of Phobos, that would be from lunar orbit, not from the surface. It's slow, but its cheap and reliable. But the product need not be sent back to Earth. If you were to set up a facility at L4 and/or L5, you could send stuff there for processing into more useful stuff. Stuff like foamed aluminum girders, for example. Or foamed steel. Or glass. Or hydrogen and oxygen. Or water. Stuff useful for making other stuff. Like a great big wheel shaped space station. Or a big space ship. Or mining equipment. Or a huge floating greenhouse. Or... Or... Or... When you look at it like that, going to Mars might not sound like so great an idea, after all. At least, not until Mars needs farmers. Phobos should be the target, because that is where you want to set up your terraforming operation, when you get to that stage of the game. And that is where you want the asteroid mining to be centered, so you can develop the mining into terraforming also. http://en.wikipedia.org/wiki/Outer_Space_Treaty http://en.wikipedia.org/wiki/Lagrangian_point
