  This Cassini image of the Saturn-facing side of icy Mimas (396 kilometers, 246 miles across) reveals the craters and long, linear chasms that cross the moon's surface.

Many of the large craters on Mimas have whimsical names from the legend of King Arthur, such as Launcelot, Merlin and Gallahad.

The image was taken in visible light with the narrow angle camera on December 14, 2004, from a distance of 902,000 kilometers (560,000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 26 degrees. The image scale is 5.4 kilometers (3.4 miles) per pixel. The image has been magnified by a factor of two and contrast enhanced to aid visibility.

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.
