The Cassini spacecraft observes the wispy terrain that covers the trailing side of Rhea.

North on Rhea (1,528 kilometers, or 949 miles across) is up and rotated 27 degrees to the right.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 22, 2007. The view was obtained at a distance of approximately 1.9 million kilometers (1.2 million miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 22 degrees. Image scale is 11 kilometers (7 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.
