  This richly textured look at Tethys (1,062 kilometers, 660 miles across) shows the huge crater Odysseus and its central mountain in relief, as well as many smaller impact sites. Vertical relief on solid solar system bodies is often most easily visible near the terminator (the line between day and night).

North on Tethys is up in this view. The lit portion of Tethys seen here is on the moon's leading hemisphere as it orbits Saturn.

The image was taken in visible light with the narrow angle camera on June 27, 2005, from a distance of approximately 490,000 kilometers (304,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or phase, angle of 117 degrees. The 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.
