Mimas (396 kilometers, 246 miles across) is caught in the spotlight beneath Saturn's rings in this amazing view from Cassini. Notable is the brightened outermost edge of the A ring beyond the narrow Keeler gap and the periodic brightening of the thin, knotted F ring.
The image was taken in visible light with the narrow angle camera on December 18, 2004, from a distance of 2 million kilometers (1.3 million miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 105 degrees. The image scale is about 12 kilometers (7.5 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.
