The Grey Mars - Roving Mars in Search of a Habitable Environment

Could Mars have ever harbored life? Thanks to NASA's latest Mars rover Curiosity, scientists are finding clues to this profound question since the rover made an extraordinary landing on the red planet in August 2012. For the first time in Mars exploration, Curiosity drilled into Martian rocks and investigated the subsurface chemistry in detail. It turned out that underneath the highly oxidized red surface was "grey Mars" material determined to have life-supporting potential. This program tracks the first year of Curiosity's adventure, and confirms an ancient environment to support life on Mars.
