Gale Crater mineralogy
Gale Crater mineralogy A colorful map of the mineralogy at Gale Crater from Ralph Milliken. Greens are phyllosilicates, blue and magenta are sulfates, red is olivine, and orange is mixed sulfates and clays. The landing site is at the top center of this image, and the rover would ideally drive to the northwestern part of the mound, where there is lots of CRISM coverage.Image: NASA / JPL-Caltech / MSSS / Ralph Milliken
