And most people forget that the ground has pressure as well.
Edit: I guess I overlooked your last line. Yes, in this sense, it would be rare for liquid water to ever exist on the surface of Mars.

Looks like a good read for this thread. -------------------- |

Melting temp depends only weakly on pressure. QUOTE Edit 2: Heres and interesting link. I found this on a quick search. Looks like a good read for this thread.
