Rhea's distinctive bright and relatively fresh-rayed crater lies in stark contrast to the large, round basin which sits along the terminator (the boundary between day and night) in this unmagnified view.

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

North on Rhea is up and rotated about 15 degrees to the left. The sunlit terrain shown here is on the moon's leading hemisphere.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Aug. 31, 2005, at a distance of approximately 1.6 million kilometers (1 million miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 52 degrees. The image scale is 10 kilometers (6 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 mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
