  Cassini surveys the south polar region of icy Rhea.

This is a similar view to PIA07572. This view is a bit farther south and has slightly different solar illumination.

Cassini flybys have shown that Rhea is not differentiated, or separated into distinct layers; instead, it appears to be a mixture of approximately 75 percent ices and 25 percent rock and metal.

Saturn's second-largest moon, Rhea is 1,528 kilometers (949 miles) wide.

The image was taken with the Cassini spacecraft narrow-angle camera on April 12, 2008 using a spectral filter sensitive to wavelengths of ultraviolet light centered at 338 nanometers. The view was acquired at a distance of approximately 345,000 kilometers (214,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 73 degrees. Image scale is 2 kilometers (1 mile) 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.
