  Craters imprinted upon other craters record the long history of impacts endured by Saturn's moon Rhea.

This view looks toward the mid-southern latitudes of the Saturn-facing side of Rhea (1528 kilometers, 949 miles across). North on Rhea is up.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Oct. 13, 2009. The view was obtained at a distance of approximately 45,000 kilometers (28,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 105 degrees. Image scale is 262 meters (860 feet) per pixel.

The Cassini Equinox Mission is a joint United States and European endeavor. 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 was designed, developed and assembled at JPL. 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.

this very old terain is such a contrast to the very young tiger stripe on Enceledus. what an astounding range of geology we see in the Saturn system.
