CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Prometheus Lurking in the Rings

Prometheus shows up bright in this image of the dark side of the rings. The bright band that appears above Prometheus in this image is the Cassini division separating the (very dark) B ring and the A ring. The C ring, interior to the B ring, is clearly visible.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Oct. 20, 2008 at a distance of approximately 1.076 million kilometers (668,000 miles) from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 26 degrees. Image scale is 6 kilometers (4 miles) per pixel.

The Cassini Equinox Mission is a joint United States and European endeavor. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter was designed, developed and assembled at JPL. 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.
