NASA’s Curiosity Mars rover is driving toward the southwest after departing a region where for several weeks it investigated a geological contact zone and rocks that are unexpectedly high in silica and hydrogen content. The hydrogen indicates water bound to minerals in the ground.
In this “Marias Pass” region, Curiosity successfully used its drill to sample a rock target called “Buckskin” and then used the camera on its robotic arm for multiple images to be stitched into a self-portrait at the drilling site….
The rover finished activities in Marias Pass on Aug. 12 and headed onward up Mount Sharp, the layered mountain it reached in September 2014. In drives on Aug. 12, 13, 14 and 18, it progressed 433 feet (132 meters), bringing Curiosity’s total odometry since its August 2012 landing to 6.9 miles (11.1 kilometers). [More at link]
