Both of Saturn's F-ring shepherd moons are seen in this Cassini
spacecraft view, which also features narrow ringlets in the
Encke gap at left. Prometheus (102 kilometers, or 63 miles
across) is captured in the act of creating another dark gore in
the F ring's inner edge. Pandora (84 kilometers, or 52 miles
across) is farther around the ring's outer edge at top. This
view looks toward the unilluminated side of the rings from about
5 degrees above the ringplane. The image was taken in visible
blue light with the Cassini spacecraft narrow-angle camera on
Dec. 6, 2007. The view was acquired at a distance of
approximately 1.7 million kilometers (1.1 million miles) from
Saturn. Image scale is about 10 kilometers (6 miles) per pixel
on both moons. 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
