AZs coating on Curiosity Rover

NASA’s Curiosity Mars rover took this selfie at a location nicknamed “Mary Anning” after a 19th century English paleontologist. Curiosity snagged three samples of drilled rock at this site on its way out of the Glen Torridon region, which scientists believe preserves an ancient habitable environment.
