CICLOPS: Cassini Imaging Central Laboratory for OPerationS

Resonance Moon and Rings
[For trouble viewing the images/movies on this page, go here]
The rings share this view with Mimas, a moon whose gravity influences the rings.

To learn more about Mimas' gravitational influences, or resonances, see PIA10421 and PIA07537. Mimas (396 kilometers, 246 miles across) was overexposed in this image and has been dimmed by a factor of four relative to the rest of the image.

This view looks toward the northern, sunlit side of the rings from about 9 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 7, 2009. The view was acquired at a distance of approximately 2.9 million kilometers (1.8 million miles) from Saturn. Image scale is 17 kilometers (11 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.
