CICLOPS: Cassini Imaging Central Laboratory for OPerationS

The Shepherd and Saturn
[For trouble viewing the images/movies on this page, go here]
Saturn's brilliant limb shines through the semi-transparent A ring, while the outer F-ring shepherd moon hangs against the black sky.

Pandora (81 kilometers, 50 miles across), along with the inner shepherd moon Prometheus, helps to keep the narrow lanes of the F ring in check.

This view looks toward the unilluminated side of the rings from about 15 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on April 5, 2008. The view was obtained at a distance of approximately 1.3 million kilometers (814,000 miles) from Pandora. Image scale is 8 kilometers (5 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.
