That there’s water on Mars – mostly in the form of ice – has been known since the discovery of the planet’s prominent polar caps.  But recent work by a team including James Wray (Georgia Tech) and Janice Bishop (SETI Institute), based on data from the Mars Reconnaissance Orbiter, has turned up evidence of subsurface chemical components that betray a warmer, wetter past for the Red Planet.

This increases the likelihood that, in its early days, Mars may have had extensive liquid water on its surface, and might possibly have spawned life.
