Hyperion's Icy Surface - July 4, 2007
In this ultraviolet image of Hyperion, produced using data taken with
UVIS 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.
