NASA's Curiosity Rover Captures Stunning Mars Views – Unlocking Mysteries of Ancient Past
Striking rock formations documented by the Curiosity rover provide evidence of a drying climate in the Red Planet’s ancient past.
NASA’s Curiosity Mars rover has been traveling through a transition zone from a clay-rich region to one filled with a salty mineral called sulfate for the past year. While the science team targeted the clay-rich region and the sulfate-laden one for evidence each can offer about Mars’ watery past, the transition zone is proving to be scientifically enlightening as well. In fact, this transition may provide the record of a major shift in Mars’ climate billions of years ago that scientists are only now beginning to grasp.
The clay minerals formed when lakes and streams once rippled across Gale Crater, depositing sediment at what is now the base of Mount …
