  The sunlight angle in this sharp view of Saturn's second-largest moon, Rhea (1,528 kilometers, 949 miles across), highlights the moon's crater-strewn surface. Cassini will fly past Rhea on November 26, 2005 at a distance of only 500 kilometers (311 miles), and will obtain very high resolution images at that time.

This view shows mainly the anti-Saturn hemisphere of Rhea and was taken in visible light with Cassini's narrow angle camera on November 1, 2004, from a distance of 1.6 million kilometers (994,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 102 degrees. North is up. The image scale is about 10 kilometers (6 miles) per pixel. The image has been slightly contrast enhanced to aid visibility of surface features.

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.
