  Cassini captures a crescent of crater-covered surface on the moon Rhea.

Lit terrain seen here is on the trailing hemisphere 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 Dec. 24, 2009. The view was obtained at a distance of approximately 652,000 kilometers (405,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 129 degrees. Image scale is 4 kilometers (2 miles) 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.
