These figures show four propeller-shaped structures discovered
by the Cassini spacecraft 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 (1,000 feet). See pia07791
for additional images and information about these features. The
figures were cropped from two original Cassini spacecraft
narrow-angle camera images and magnified for visibility. The
images were then re-projected so that orbital motion is to the
left and Saturn is up. The unseen moonlets lie in the center of
each structure. 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 Cassini-Huygens mission is a cooperative project
of NASA, the European Space Agency and the Italian Space Agency.
