The cratered surface Saturn's moon Mimas is seen in this image taken NASA's Voyager 1 on Nov. 12, 1980 from a range of 425,000 kilometers (264,000 miles).

The cratered surface Saturn's moon Mimas is seen in this image taken by Voyager 1 on Nov. 12, 1980 from a range of 425,000 kilometers (264,000 miles). Impact craters made by the infall of cosmic debris are shown; the largest is more than 100 kilometers (62 miles) in diameter and displays a prominent central peak. The smaller craters are abundant and indicate an ancient age for Mima's surface. The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
