CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Spotting Prometheus

The flattened, potato-like form of Prometheus glides silently within the Roche Division, between Saturn's A and F rings.

Prometheus (86 kilometers, 53 miles across) is on the side of the rings closest to Cassini in this view. The image looks toward the sunlit side of the rings from about a degree below the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 2, 2008. The view was acquired at a distance of approximately 1.1 million kilometers (660,000 miles) from Prometheus. Image scale is 6 kilometers (4 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.
