NASA's Cassini spacecraft watches Saturn's small moon Epimetheus orbiting beyond the planet's rings. Epimetheus orbits beyond the thin F ring near the bottom center of this view.

The Cassini spacecraft watches Saturn's small moon Epimetheus orbiting beyond the planet's rings.

See PIA09813 and PIA06226 for closer views of this moon. Epimetheus (70 miles, or 113 kilometers across) orbits beyond the thin F ring near the bottom center of this view and is farther from the spacecraft than the rings are here. This view looks toward the southern, unilluminated side of the rings from about 1 degree below the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Dec. 30, 2011. The view was acquired at a distance of approximately 1.5 million miles (2.4 million kilometers) from Epimetheus. Image scale is 9 miles (14 kilometers) 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 mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
