This view from NASA's Dawn spacecraft features the rugged rim of Occator Crater at left. A number of thin fractures are visible, roughly parallel to the rim.
Dawn took this image on April 18, 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.
