Caption:

Prometheus is caught here, in the act of pulling a new streamer out of the F ring’s inner edge. Trailing behind (above the moon in the image) are previous dark gores that Prometheus (102 kilometers, or 63 miles across) has created.

See PIA08397 for a thorough description of how the moon creates these features.

This view looks toward the unilluminated side of the rings from about 5 degrees above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 14, 2007. The view was obtained at a distance of approximately 1.7 million kilometers (1.1 million miles) from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 67 degrees. Image scale is 10 kilometers (6 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 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.
