The northern polar region of Saturn's moon Tethys seen in this Cassini
flyby image is a ponderously ancient surface.
Above the prominent peaked crater Telemachus are the remnants of a very
old crater (at the 10 o'clock position relative to Telemachus) named
Teiresias. The ancient impact site is so badly overprinted and eroded by
impact weathering and degradation that all that remains is a circular
pattern of hummocks that mark where the old crater rim existed.
This view is centered on terrain at approximately 1.2 degrees south
latitude and 342 degrees west longitude on Tethys. The view is rotated so
that north is about 40 degrees to the right.
This clear filter view was taken during Cassini's close approach to
Tethys on Sept. 24, 2005. The image was acquired using the Cassini
spacecraft narrow-angle camera at a distance of approximately 69,200
kilometers (43,000 miles) from Tethys and at a Sun-Tethys-spacecraft, or
phase, angle of 21 degrees. Image scale is 410 meters (1,350 feet) 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.
