Lit brilliantly by the sun, the moon Rhea shows off its huge ray crater.
The view was obtained at a distance of approximately 812,000 kilometers (505,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 4 degrees. This view looks toward the leading hemisphere of Rhea (1528 kilometers, 949 miles across). North on Rhea is up and rotated 30 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 26, 2009. Image scale is 5 kilometers (3 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.
