CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Trailing Prometheus
[For trouble viewing the images/movies on this page, go here]
Saturn's F ring displays magnificent structure following the passage of Prometheus.

Atlas (30 kilometers, 19 miles across) is seen between the A and F rings, above center.

This view looks toward the unilluminated side of the rings from about 28 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Jan. 23, 2008. The view was acquired at a distance of approximately 1.7 million kilometers (1.1 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 41 degrees. Image scale is 10 kilometers (6 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.
