CICLOPS: Cassini Imaging Central Laboratory for OPerationS
Lost Arc

This low elevation image shows the G ring arc recently discovered by Cassini. This faint arc of material is maintained by a gravitational interaction with the moon Mimas.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Oct. 20, 2008 at a distance of approximately 1.185 million kilometers (736,000 miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 23 degrees. Image scale is 7 kilometers (4 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.
