Ice on Mars

LOS ANGELES — Scientists believe NASA's Phoenix Mars lander exposed bits of ice while recently digging a trench in the soil of the Martian arctic, the mission's principal investigator said Thursday.

This would be good news -- I guess. What do I know? But you figure ice is basically petrified water, right? And water means there could be life, and clues as to the planet's past, or something.

Anyway, knowledge is a good thing, for those in the know. In one of the articles I saw it said they could be vast quantities of ice in there somewhere. And that would be greater. If it's like on earth, we might find preserved mammoths or inhabitants from long ago. Or more clues about the planet's history.
