False-color view of part of Meridiani Planum, about 250 miles (400 kilometers) northeast of where Mars rover Opportunity landed. The image was taken from NASA’s Mars Odyssey orbiter using its Thermal Emission Imaging System (THEMIS) - a camera that images Mars in 5 visible and 10 infrared “colors.” The image combines daytime and nighttime infrared views. Reddish areas have more rocks and hardened sediments, while bluish areas feature more dust, sand, and fine-grain material. Image Credit: NASA/JPL/Arizona State University.
