Saturn's Satellite Dione

Large bright streaks are seen to cross the face of Saturn's moon Dione in this photograph taken by NASA's Voyager 1 on Nov. 12, 1980 from a distance of 695,000 kilometers (417,000 miles). Higher resolution views of Dione taken by Voyager 1 show some of these streaks to be grooves that may be the result of fracturing in the satellite's surface. The Voyager Project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, California.
