Scientists have had a long-standing theory that Mars used to have surface water. But for that to happen, the planet also would have needed to be warmer, with higher air pressure. That has led them ...

WASHINGTON — A mineral called siderite found abundantly in rock drilled by a NASA rover on the surface of Mars is providing fresh evidence of the planet's warmer and wetter ancient past when it ...

In January, pictures taken by NASA's Mars Reconnaissance Orbiter (MRO) showed the Martian surface covered by frozen sand dunes in the northern hemisphere. Unlike the dunes on Earth, which are ...
