CICLOPS: Cassini Imaging Central Laboratory for OPerationS

A-Ring Propeller
[For trouble viewing the images/movies on this page, go here]
A propeller-shaped structure, created by an unseen moon, can be seen in Saturn's A ring.

The propeller, which looks like a small, dark line interrupting the bright surrounding ring material, is in the upper left of this image near the edge of the Keeler Gap. See PIA12790 to learn more about propellers.

This view looks toward the southern, unilluminated side of the rings from about 16 degrees below the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on June 3, 2010. The view was acquired at a distance of approximately 279,000 kilometers (173,000 miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 16 degrees. Image scale is 1 kilometer (4,301 feet) 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.
