Mars's atmospheric pressure is so low that water ice sublimes -- it goes directly from solid to gas without passing through a liquid phase, as dry ice (frozen CO2) does here on earth.

Date: 2006-12-07 12:18 am (UTC)The gullies they've noticed have probably only had flowing water once in the last decade -- and probably not for a *long* time before the last decade. After all, they're noticeable specifically because they're different from the pictures we took ten years ago. Most likely scenario is that there's a block of subsurface ice that has melted for some reason... so it's not quite liquid water under the surface, and it's only liquid for a very brief period before it either freezes or boils.
Still very cool stuff, though. :)
