This half-lit view beautifully captures the ponderously old and cratered surface of Saturnís icy moon Rhea (1,528 kilometers, 949 miles across).
The sunlit terrain shown here is on the moonís leading hemisphere, on the side of Rhea that always faces toward Saturn. North is up and rotated 20 degrees to the left.
The image was taken in visible light with the narrow angle camera on August 21, 2005, from a distance of approximately 922,000 kilometers (573,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 88 degrees. The image scale is 6 kilometers (4 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.
