The In-Between Moons
Cassini looks up from beneath the ringplane to spot Prometheus and Atlas
orbiting between Saturn's A and F rings.
Prometheus is 102 kilometers (63 miles) across. Atlas is 20 kilometers (12
The F ring displays its characteristic clumps, while scientists are
watching diligently for signs of tiny, embedded moons. Prometheus is
responsible for some of the clumpy structure in the F ring.
The image was taken in visible light with the Cassini spacecraft
narrow-angle camera on Aug. 28, 2005, at a distance of approximately 2.3
million kilometers (1.4 million miles) from Saturn. The image scale is
about 13 kilometers (8 miles) per pixel.
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 mission for NASA's Science Mission Directorate, Washington, D.C. The
Cassini orbiter and its two onboard cameras were designed, developed and
assembled at JPL. The imaging operations center is based at the Space
Science Institute in Boulder, Colo.
