  This false-color picture of Rhea from Cassini enhances slight differences in natural color across the moon's face. The extreme north and south latitudes have a notable difference in hue compared to the mid-latitudes.

This view of Rhea is a composite of images taken using filters sensitive to green (centered at 568 nanometers) and infrared light (two infrared filters, centered at 752 and 930 nanometers respectively) and has been processed to accentuate subtle color differences.

The images were taken with the narrow angle camera on February 18, 2005, from a distance of approximately 890,000 kilometers (553,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 116 degrees. The image scale is 5 kilometers (3 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 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.
