  This Cassini image shows a nearly half-full Mimas (396 kilometers, 246 miles across) beyond Saturn's rings. The image was contrast enhanced to make visible the reflected light from Saturn which illuminates the dark side of Mimas and to improve the visibility of the faint F ring.

The image was taken in visible light with the narrow angle camera on September 11, 2004, from a distance of 8.9 million kilometers (5.5 million miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 83 degrees. The image scale is 53 kilometers (33 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.
