  Two large craters lie along the boundary between day and night on Rhea (1,528 kilometers, 949 miles across). The bright spots in the middle of each crater may be prominent central peaks.

This view shows principally the trailing hemisphere on Rhea. The image has been rotated so that north on Rhea is up.

The image was taken in visible light with the narrow angle camera on January 19, 2005, from a distance of approximately 1.9 million kilometers (1.2 million miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 121 degrees. Resolution in the original image was 11 kilometers (7 miles) per pixel. The image has been contrast-enhanced and magnified by a factor of two to aid visibility.


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.
