Prometheus--lit partly by direct sunlight, and partly by saturnshine--pulls at material in the inner portion of the F ring.
Saturnshine is sunlight reflected by the Ringed Planet, which often brightens the night sides of Saturn's moons.
This view looks toward Prometheus (86 kilometers, 53 miles across) and the unilluminated side of the rings from about 41 degrees above the ringplane.
The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 10, 2008. The view was obtained at a distance of approximately 1.2 million kilometers (743,000 miles) from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 59 degrees. Image scale is 7 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.
