Cassini looks down upon Rhea, whose cratered surface was already ancient before any complex life developed on Earth. The terrain seen here has probably changed little in the past billion years.
This view shows terrain on the Saturn-facing hemisphere of Rhea (1,528 kilometers, 949 miles across). North is up.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 21, 2006 at a distance of approximately 94,000 kilometers (59,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 109 degrees. Image scale is 558 meters (1,832 feet) 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 Cassini-Huygens mission for NASA's Science Mission Directorate, Washington, D.C. 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.
