Mars Was Wet; Now Let's Move On . . .

Conditions on vast plain on Mars could have been suitable for life, Cornell rover scientist Squyres states in special Science issue

"Now a Cornell University-led Mars rover science team reports on the historic journey by the rover Opportunity, which is exploring a vast plain, Meridiani Planum, and concludes with this observation: 'Liquid water was once present intermittently at the martian surface at Meridiani, and at times it saturated the subsurface. Because liquid water is a key prerequisite for life, we infer that conditions at Meridiani may have been habitable for some period of time in martian history.'"
