i would imagine the less supplies they have to send up the better. IIRC, Luna has an atmosphere that is unhabitable when compared to Mars, but then, I guess everything is in some sort of contained dome so not sure if that is even relevant.
secondly, i would imagine a source of water would be needed. they are guessing that somewhere deep in Mars, there may be water left. but definitely at the temperatures on the surface, water simply can't exist on the surface.
