  Cassini looks up from beneath the ringplane to spot Prometheus (86 kilometers, 53 miles across) and Atlas (30 kilometers, 19 miles across) orbiting between Saturn's A and F rings.

The F ring displays its characteristic clumps while scientists are watching diligently for signs of tiny, embedded moons. Prometheus is responsible for some of the clumpy structure in the F ring.

The image was taken in visible light with the narrow angle camera on August 28, 2005, from a distance of approximately 2.3 million kilometers (1.4 million miles) from Saturn. The image scale is about 13 kilometers (8 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.
