In this ultraviolet image of Hyperion, produced using data taken with
Cassini's Ultraviolet Imaging Spectrograph during the September 2005 close
flyby, brightness contrasts are due to both topographic and compositional
variations across the surface. The brightest regions are exposed water ice
in the rim of the crater that dominates the hemisphere in view.
This new ultraviolet map (left) is shown next to a previously released
image (right) taken by the Imaging Science Subsystem (see PIA07761).
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 was designed, developed and assembled at JPL. The
ultraviolet imaging spectrograph was designed and built at, and the team
is based at the University of Colorado, Boulder. The imaging operations
center is based at the Space Science Institute in Boulder, Colo.
