It's Crater-palooza on Dwarf Planet Ceres (New Photo)

Dawn captured the image on May 23, when the probe was just 3,200 miles (5,100 kilometers) from Ceres. The photo's resolution is about 1,600 feet (480 meters) per pixel, scientists said.
"The view shows numerous secondary craters, formed by the re-impact of debris strewn from larger impact sites. Smaller surface details like this are becoming visible with increasing clarity as Dawn spirals lower in its campaign to map Ceres," NASA officials wrote in an image description today (May 28).
Dawn orbited the 330-mile-wide (530 km) Vesta from July 2011 through September 2012 and reached Ceres, which is 590 miles (950 km) across, this March. In the process, Dawn became the first spacecraft to orbit two objects beyond the Earth-moon system, as well as the first to circle a dwarf planet.
Dawn is studying Ceres from a series of progressively closer-in orbits. The craft's first science orbit lay about 8,400 miles (13,500 km) from the dwarf planet's surface; Dawn is currently spiraling down to a 2,700-mile-high (4,400 km) orbit, which it should reach on June 3.
By the time Dawn wraps up its mission in June 2016, it will be eyeing Ceres' intriguing surface from just 230 miles (375 km) away.
