CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Like Spokes of Old
[For trouble viewing the images/movies on this page, go here]
Cassini spots a couple of large, wedge-shaped spokes in Saturn's B ring. These spokes are similar in appearance to those seen by the Voyager spacecraft (see PIA02275).

Prometheus (86 kilometers, 53 miles across) can be spotted interior to the narrow F ring at left. Pan (28 kilometers, 17 miles across) appears within the Encke Gap, below center.

This view looks toward the sunlit side of the rings from about 26 degrees below the ringplane. Pan has been brightened for visibility.

The image was taken in visible light with the Cassini spacecraft wide-angle camera on July 8, 2008. The view was acquired at a distance of approximately 749,000 kilometers (465,000 miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 31 degrees. Image scale is 41 kilometers (26 miles) per pixel.

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.
