  Saturn's irregularly shaped moon Hyperion is completely covered with large pits from which much of its material has been blasted by impacts, never to return. The moon's surface gravity is so low that crater-ejected material often escapes Hyperion entirely.

Hyperion is 270 kilometers (168 miles) across.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Oct. 21, 2007. The view was obtained at a distance of approximately 151,000 kilometers (94,000 miles) from Hyperion and at a Sun-Hyperion-spacecraft, or phase, angle of 111 degrees. Image scale is 906 meters (0.6 mile) 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.
