MARCH-APRIL 2016 Ceresian craters collection T his view from NASA's Dawn spacecraft captures a portion of the southern hemisphere of Ceres. The image of this unnamed crater is centered at appro- ximately 46 degrees south latitude, 101 degrees east lon- gitude. Dawn captured the scene on Dec. 20, 2015 from its low-altitude mapping orbit (LAMO), at an approxi- mate altitude of 240 miles (385 kilometers) above Ceres. The image resolution is 120 feet (35 meters) per pixel. T he northeast rim of Sintana Crater on Ceres. The crater's steep rim is shadowed in this particular view. The crater density along this area of Sintana's rim (both interior and exterior) appears to be roughly the same, and is dominated by small impacts. The image is centered at approximately 45.6 de- grees south latitude, 49.2 degrees east longitude. Dawn captu- red the scene on Jan. 1, 2016, from its low-altitude mapping orbit (LAMO), at an altitude of 234 miles (376 kilometers) above Ceres. The image resolution is 115 feet (35 meters) per pixel. NASA/JPL-Caltech/UCLA/MPS/DLR/IDA ▼ ▼
