The Cassini spacecraft examines the Maxwell Gap—the large, dark
division at center—which is surrounded on either side by the broad,
isolated and bright ring regions, or "plateaus," of Saturn's outer C ring.
See PIA08389 for a labeled Cassini map of the rings.
The gap is named for James Clerk Maxwell, the famous Scottish physicist
who showed that Saturn's rings must consist of countless individual
particles, rather than solid, concentric ringlets.
Prometheus (102 kilometers, 63 miles across) wanders past at the bottom of
this scene, which looks toward the sunlit side of the rings from about 2
degrees below the ringplane.
The image was taken in visible light with the Cassini spacecraft
narrow-angle camera on Jan. 29, 2008. The view was obtained at a distance
of approximately 1.1 million kilometers (697,000 miles) from Saturn. Image
scale at the center of the scene is about 7 kilometers (4 miles) per pixel
in the radial, or outward from Saturn, direction.
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.
