  This Cassini image shows Rhea's cratered surface, with impact craters near the terminator thrown into sharp relief. Rhea is Saturn's second-largest moon, at 1,528 kilometers (949 miles across).

This view shows the leading hemisphere on Rhea. North is up and tilted 23 degrees to the left.

The image was taken with the narrow angle camera on March 12, 2005, through a filter sensitive to wavelengths of ultraviolet light centered at 338 nanometers. The view was obtained from a distance of approximately 1.5 million kilometers (950,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 70 degrees. Resolution in the image is 9 kilometers (6 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.
