This image captured by NASA Mars Reconnaissance Orbiter MRO covers diverse surface units on the floor of eastern Coprates Chasma in eastern Valles Marineris. The bedrock has diverse minerals producing wonderful color contrasts. In over 10 years of orbiting Mars, HiRISE has acquired nearly 50,000 large images, but they cover less than 3 percent of the Martian surface. https://photojournal.jpl.nasa.gov/catalog/PIA21606
