Voyager 2 obtained this view of Saturn's moon Tethys on Aug.25 from a distance of 540,000 kilometers (335,000 miles). It shows the numerous impact craters and fault valleys of a very ancient surface. Tethys itself is 1,090 km. (675 mi.) in diameter, and the great chasm seen at the top of this image extends 1,700 km. (1,050 mi.), halfway across the satellite. The largest impact crater visible here is 90 km. (55 mi.) in diameter. The Voyager project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
