  This color view shows off two of icy Tethys' largest craters: Odysseus in the northern hemisphere and Melanthius in the south. The moon's surface grows notably darker northward of the equator.

Viewing the scene in color makes visible the apparent contamination of Saturn's rings by non-water ice materials.

The view shows the side of Tethys (1,062 kilometers, 660 miles across) which always faces away from Saturn. Images taken using red, green and blue spectral filters were composited to create this color view. The images were taken with the narrow angle camera on September 11, 2005, from a distance of approximately 2 million kilometers (1.2 million miles) from Tethys. The image scale is 12 kilometers (7 miles) per pixel on Tethys.

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.
