This view of Saturn's second-largest moon, Rhea (1,528 kilometers, 949 miles across), shows some of the large craters which cover its surface. There is a bright feature near the moon's right limb, possibly a large, rayed crater or bright icy material exposed by internal processes.
The image was taken in visible light with the narrow angle camera on September 26, 2004, from a distance of 7.1 million kilometers (4.4 million miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 75 degrees. The image scale is 43 kilometers (27 miles) per pixel. The image has been magnified by a factor of four and contrast-enhanced to aid visibility.
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.
