The shepherd moon Prometheus (86 kilometers, 53 miles across) reveals its elongated, irregular form to Cassini in this image. The moon’s long axis points toward Saturn.
This view shows the southern part of the moon’s anti-Saturn side (the face that always points away from Saturn).
The image was taken in visible red light with the narrow angle camera on June 7, 2005, from a distance of approximately 438,000 kilometers (272,000 miles) from Prometheus. Resolution in the original image was 3 kilometers (2 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.
