We know that Mars has plenty of H2O, and that like any other world it gets warmer as you go down, so I think their must be liquid water at some depth on Mars (to be drilled for perhaps by future inhabitants). Of course when it has the temerity to appear at the surface it immediately freezes and pretty soon sublimes away, so we're looking at the dry rind of a wet planet.
How near the surface the liqiud phase gets and how often are great questions. I hope we get answers from the current generation of Mars explorers. |
