A heavily cratered surface is apparent in this photo of Saturn's
satellite Tethys, taken Nov. 12, 1980, by Voyager 1 from a distance
of 570,000 kilometers (354,000 miles). Other photos of Tethys
showed the opposite hemisphere, dominated by what appears to be
a large impact crater or hill. Tethys is about 1,000 kilometers
(600 miles) in diameter and is composed largely of ice.
Voyager 1 made its closest approach to Saturn Nov. 12, 1980, and
is now en route out of the solar system. Voyager 2 will make its
closest approach to Saturn Aug. 25, 1981, and will then continue
on toward Uranus. It will arrive at that distant planet in
January 1986. The Voyager Project is managed for NASA by
the Jet Propulsion Laboratory, Pasadena, California.
