NASA's Dawn spacecraft views a crater at top center that touches the rim of Messor Crater (25 miles, 40 kilometers), shown at left. The view is similar to PIA20572, but from a different viewing angle. Dawn took this image on May 30, 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/PIA20866
