CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Spotting the Shepherd
[For trouble viewing the images/movies on this page, go here]
Across the darkened expanse of Saturn's rings, Cassini spies one of the F-ring shepherd moons.

Pandora (81 kilometers, 50 miles across) orbits Saturn just beyond the outer edges of the F ring.

This view looks toward the unilluminated side of the rings from about 8 degrees above the ringplane. At lower right, ring shadows are cast upon the planet.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 29, 2007. The view was obtained at a distance of approximately 2 million kilometers (1.3 million miles) from Pandora. Image scale is 12 kilometers (8 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.
