You sure that's not a potato?

It's certainly taken a lot of meteor and asteroid hits...........

Definitely. Mars has as well. Our own Moon was believed by many to have been cratered by volcanism (this seems incomprehensible today) but the Apollo landings put the lie to that, so the volcano geeks moved the claims to another planet. The Ries Basin study E Shoemaker did in the 1950s had already started the process of ejecting them from Earth. :')

  "There is something of a paradox about Mars," agrees Joshua Bandfield of Arizona State University in Tempe. His team recently showed that the planet has no large deposits of carbonates, which should have formed if giant pools of water had persisted on the surface. Bandfield suggests that liquid water must have occasionally burst out of the ground, carving channels and gullies, but that it quickly froze again in the frigid Martian climate.
