The Atlas Ring
September 9, 2004
A new found ring of material, S/2004 1 R, in the orbit of Saturn's moon Atlas has been seen in this view of the region between the edge of Saturn's A ring and the F ring.
The image was taken by the Cassini spacecraft wide angle camera on July 1, 2004, just after the spacecraft had crossed the ring plane following Saturn orbit insertion.
The maximum radial resolution is approximately 7 kilometers (4 miles) per pixel. The region from the A ring to the F ring spans some 3,500 kilometers (2,200 miles). The image has been enhanced to show the presence of faint ring material just beyond the edge of the A ring and in the orbit of Atlas (indicated by the red line in the image on the right). The moon Prometheus (102 kilometers or 63 miles across) can be seen close to the F ring at the lower left of the image.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Cassini-Huygens mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging team is based at the Space Science Institute, Boulder, Colo.
