CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Rhea's Bright Blemish
[For trouble viewing the images/movies on this page, go here]
This view of Rhea (1,528 kilometers, 949 miles across) shows the tremendous bright splat that coats much of the moon's leading hemisphere. The bright feature may be impact-related and is visible in other Cassini images of Rhea (see PIA07539).

North on Rhea is up in this view.

The image was taken in visible green light with the narrow angle camera on June 25, 2005, from a distance of approximately 1.1 million kilometers (700,000 miles) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of less than one degree. Resolution in the original image was 7 kilometers (4 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.
