Phobos and Deimos Once a Single Moon?
blamanj writes "Phobos (fear) and Diemos (panic), the twin moons of Mars have caused astronomers grief for years, as conventional hypotheses about the moons either violate physical laws or have difficulty accounting for their observed orbits. Now a new hypothesis conjectures that they were once a single moon, that broke apart in an ancient catastrophe."
Walking is generally important, unless you want the astronouts to stay seated all the time. If there were in zero-g, they could float. But there's enough gravity to make that annoying, but not nearly enough to walk. Also, they'd still need to do daily exercises to keep their bones and muscles from atrophying.
You're making a pretty large leap from "probably water" to "send fuel back to Earth". There probably isn't that much water to start with, given that these guys are a few kilometers across.
It's not a good idea. You're better off parking a space station in orbit on its own. It'll be easier to handle, more flexible and you don't lose any advantages.
