This highest-resolution view of Tethys was obtained Aug. 26 when Voyager 2 was 120,000 kilometers (74,500 miles) from this satellite of Saturn. This image was taken 1 1/2 hours after the spacecraft passed through the planet's ring plane. The smallest features visible here are about 2.2 km. (1.4 mi.) across. The heavily cratered terrain implies a very old surface that has changed little since shortly after the solar system formed. Tethys is a bright object made largely of ice; it has a diameter of 1,050 km. (650 mi.). The Voyager project is managed for NASA by the Jet Propulsion Laboratory, Pasadena, Calif.
