Rhea has been heavily bombarded by impacts during its history. In this Cassini image the moon displays what may be a relatively fresh, bright, rayed crater near Rhea's eastern limb. Rhea is 1,528 kilometers (949 miles) across.
This view is centered on the side of Rhea that faces away from Saturn as the moon orbits. The image was taken in visible light with the Cassini spacecraft narrow angle camera on Nov. 10, 2004, at a distance of 3.6 million kilometers (2.2 million miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 86 degrees. North is up. The image scale is 21 kilometers (13 miles) per pixel. The image has been magnified by a factor of two and contrast enhanced to aid visibility of surface features.
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 team is based at the Space Science Institute, Boulder, Colo.
