Developing a stratigraphic column for Gale Crater’s floor
After more than 100 sols (Martian days) in Gale Crater, NASA’s Curiosity rover has driven some 500 meters (1,600 feet), traversing several rock units. A sketch of the crater floor’s geological history is emerging. On its half-kilometer drive from its … Continue reading
