Eons of a Cold, Dry, Dusty Mars, Science
Excerpts: (...) starting to build a case for a volcanic planet only gently touched by the chemical alteration that water has wreaked on Earth for billions of years. In the emerging view, a perpetually frigid climate has kept Mars's modest store of water locked up as ice most of the time. The surface may never have been particularly hospitable to life, at least not for long. If so, the search for signs of life will have to focus on the martian interior and its rare surface exposures.
