Full-Res: PIA07557

This richly textured look at Saturn’s moon Tethys 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). Tethys is 1,071 kilometers (665 miles) across.

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 Cassini spacecraft narrow-angle camera on June 27, 2005, at 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 mission for NASA’s Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
