  Cassini views the rugged surface of Mimas--half lit by the Sun, and half lit by reflected light from Saturn. On the sunlit western limb lies the great Herschel impact crater.

The view looks toward a region centered on 50 degrees west longitude on Mimas (396 kilometers, 246 miles across). North is up and rotated 9 degrees to the right.

The image was taken in polarized green light with the Cassini spacecraft narrow-angle camera on Dec. 2, 2007. The view was obtained at a distance of approximately 625,000 kilometers (388,000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 96 degrees. Image scale is 4 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.
