CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Streamer Channel

Cassini focuses on a streamer-channel feature in Saturn's F ring. These features are created by the moon Prometheus as it closely approaches the ring once per orbit (see PIA08397).

This view looks toward the unilluminated side of the rings from about 36 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Sept. 30, 2008. The view was acquired at a distance of approximately 970,000 kilometers (602,000 miles) from Saturn and at a Sun-ring-spacecraft, or phase, angle of 45 degrees. Image scale is 5 kilometers (3 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.

Strange and beautiful; what is the creature that will emerge from these ripples?
A mesmerising experience once again.
