NASA's Cassini spacecraft captured this image showing Saturn's icy moon Rhea taking center stage, with cameo appearances by Saturn's rings and three clearly visible moons. In this image, Dione appears just above Rhea. Tethys is the larger circle toward the upper left, and Epimetheus is the smaller dot to the left of Rhea. Prometheus is to the left of Dione, but barely distinguishable as a speck embedded in the rings. This wide-angle image was taken on Jan. 11, 2011, from a distance of approximately 60,000 kilometers away (37,000 miles) above Rhea.
This image has not been validated or calibrated. A validated/calibrated image will be archived with the NASA Planetary Data System in 2012.

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 in Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.
