The Cassini spacecraft takes in a southern view of the scarred face of icy
Tethys.
The moon's south pole is at bottom center, just above the terminator. To
the left of the pole is the crater Melanthius, with its complex of central
peaks poking upward into sunlight. On the limb at right, Ithaca Chasma
extends northward. The smoothness of the limb is interrupted at the 11
o'clock position by the rim of the crater Odysseus. A belt of darker
terrain girdles the moon's equator.
This is a similar view to that shown in PIA09918.
This view shows terrain to the west of that seen in the earlier image.
Lit terrain seen here is on the leading hemisphere of Tethys (1,062
kilometers, 660 miles across). North is up and rotated 9 degrees to the
right.
The image was taken in visible green light with the Cassini spacecraft
narrow-angle camera on May 10, 2008. The view was acquired at a distance
of approximately 477,000 kilometers (296,000 miles) from Tethys and at a
Sun-Tethys-spacecraft, or phase, angle of 44 degrees. Image scale is 3
kilometers (2 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.
