This view from NASA's Dawn spacecraft shows an area within the floor of the Mondamin impact basin, which lies in the southern hemisphere of Ceres. Mondamin Crater is about 78 miles (126 kilometers) in diameter. Dawn took this image on June 3, 2016, from its low-altitude mapping orbit, at a distance of about 240 miles (385 kilometers) above the surface. The image resolution is 120 feet (35 meters) per pixel. http://photojournal.jpl.nasa.gov/catalog/PIA20948

This southern hemisphere scene from dwarf planet Ceres encompasses parts of the craters Mondamin and Darzamat. Mondamin, which is 78 miles (126 kilometers) wide, is the large crater located in the top half of the image. Darzamat, at 57 miles (92 kilometers) wide, is at bottom-right. Dawn took this image on Oct. 19, 2016, from its second extended-mission science orbit (XMO2), at a distance of about 920 miles (1,480 kilometers) above the surface. The image resolution is about 460 feet (140 meters) per pixel. http://photojournal.jpl.nasa.gov/catalog/PIA21235
