  The pockmarked crescent of Tethys displays slightly darker terrain in a band at its equator. The rim of the great crater Odysseus lurks on the terminator.

Lit terrain seen here is on the leading hemisphere of Tethys (1,062 kilometers, 660 miles across). North is up.

The image was taken in visible light with the Cassini spacecraft wide-angle camera on Aug. 29, 2007. The view was obtained at a distance of approximately 56,000 kilometers (35,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 105 degrees. Image scale is 3 kilometers (2 miles) per pixel.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. The imaging team consists of scientists from the US, England, France, and Germany. The imaging operations center and team lead (Dr. C. Porco) are based at the Space Science Institute in Boulder, Colo.
