Curiosity Discovers Environment Where Life Could have Thrived on Ancient Mars
This set of images shows the results from the rock abrasion tool from Opportunity (left) and the drill from NASA’s Curiosity rover (right). Note how the rock grindings from Opportunity are brownish red, indicating the presence of hematite, a strongly oxidized iron-bearing mineral. Such minerals are less supportive of habitability and also may degrade organic compounds. On the right is the hole produced by Curiosity during the first drilling into a rock on Mars to collect a sample from inside the rock. In this case, the rock produced gray tailings — not red — suggesting the presence of iron that is less oxidized. Curiosity also found clay minerals that form in more neutral water friendly to the formation of life. Credit: NASA
After analyzing the first powder ever drilled from the interior of a Martian rock, NASA’s Curiosity rover discovered some of the key chemical ingredients necessary for life to have thrived on early Mars billions of years ago.
Curiosity has achieved her goal of discovering a habitable environment on the Red Planet, mission scientists reported today at a briefing held at NASA headquarters in Washington, D.C.
Data collected by Curiosity’s two analytical chemistry labs (SAM and CheMin) confirm that the gray powder collected from inside the sedimentary rock where the rover is exploring – near an ancient Martian stream bed – possesses a significant amount of (…)
