Terby Crater

Erosion reveals several rock layers in Terby Crater, a potential landing site for future Mars missions. The 100-mile crater is located on the northern edge of the planet's Hellas Planitia region and is of interest to scientists because of its apparent modification by liquid water. The HiRISE camera on NASA's Mars Reconnaissance Orbiter imaged the crater in April. HiRISE is controlled from the University of Arizona in Tucson. Image: NASA/JPL/University of Arizona
