  These figures show the four propeller-shaped structures discovered in close-up images of Saturn's A ring.

The propellers are about 5 kilometers (3 miles) long from tip to tip, and the radial offset (the "leading" dash is slightly closer to Saturn) is about 300 meters (1000 feet). See PIA07792 and PIA07791 for additional images and information about these features.

The figures were cropped from two original Cassini spacecraft narrow angle camera images (taken during Saturn orbit insertion on July 1, 2004) and magnified for visibility. The images were then reprojected so that orbital motion is to the left, and Saturn is up. The unseen moonlets lie in the center of each structure.

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, D.C. 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.

Very good images, but which moons they show?
