Three of Saturn's small moons straddle the rings in this image. From left to right are Pandora, Prometheus and, near the top right, Epimetheus.

Pandora (81 kilometers, 50 miles across) and Prometheus (86 kilometers, 53 miles across) are closest to Cassini. Epimetheus (113 kilometers, 70 miles across) is on the far side of the rings.

This view looks toward the northern, sunlit side of the rings from just above the ringplane. The shadow of Saturn is cast upon the rings, darkening the middle of the image from left to right.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 27, 2009. The view was acquired at a distance of approximately 2.4 million kilometers (1.5 million miles) from Epimetheus and 2.2 million kilometers (1.4 million miles) from Prometheus and Pandora. Image scale is 14 kilometers (9 miles) per pixel on Epimetheus and 13 kilometers (8 miles) per pixel on Prometheus and Pandora.

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.
