Epimetheus and the Dark Side
[For trouble viewing the images/movies on this page, go here]
Epimetheus is a lonely dot beyond Saturn's unlit-side rings. The little moon appears at lower left, outside the narrow F ring.

Several very faint spokes lurk in the B ring, at right.

This view looks toward the unlit side of the rings from about 49 degrees above the ringplane. Epimetheus is 113 kilometers (70 miles) across.

The image was taken in visible green light with the Cassini spacecraft wide-angle camera on Dec. 17, 2006 at a distance of approximately 1.1 million kilometers (700,000 miles) from Saturn. Image scale is 63 kilometers (39 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.
