Icy Rhea (1528 kilometers, 950 miles across), Saturn's second largest moon, hangs before Cassini in this narrow angle camera image, showing just a hint of its crater-pocked surface.
The image was taken visible light on August 25, 2004, from a distance of 8.8 million kilometers (5.5 million miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 84 degrees. The image scale is 53 kilometers (33 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.
