CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Above Rhea's South Pole

Cassini looks upward at the south polar region on Rhea (1,528 kilometers, 949 miles across) during a recent distant encounter. Rhea's icy surface is so heavily saturated with impact craters that the moon's limb, or edge, has a rugged, bumpy appearance.

The bright splotch seen here near upper right is impact ejecta from a relatively fresh crater (see PIA06648 for another view of this bright feature).

The image was taken with the narrow angle camera on July 14, 2005, from a distance of approximately 342,000 kilometers (212,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 36 degrees. The image was obtained using a filter sensitive to wavelengths of infrared light centered at 298 nanometers. The 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.
