摘要

描述
English: Multiple impact craters are seen on the ancient surface of Saturn's moon Rhea in this picture taken by Voyager 1 on Nov. 12, 1980 at a range of 73,000 kilometers (45,000 miles). The craters closely resemble those on Mercury and Earth's Moon. Many of the craters have central peaks formed by rebound of the floor during the explosive formation of the crater. The craters are old and degraded by later impacts. Crater diameters seen are as large as approximately 75 kilometers (45 miles). Many have sharp rims and appear relatively fresh while others are very shallow and have subdued rims, indicative of their antiquity. The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
