Tethys and Hyperion Flyby - Sept. 24 and 26, 2005
This week Cassini will play a doubleheader with two flybys of Saturn's
moon's Tethys (Sept. 24) and Hyperion (Sept. 26). Cassini will be
eye-to-eye with Tethys' giant Odysseus impact-crater. Cassini's close
brush with the chaotic, tumbling Hyperion might tell us whether it is
a rubble pile.
Scientists also hope to be able to shed more light on the following:
* The origin of the huge canyon-like feature named Ithaca Chasma on
Tethys is not completely understood, but it might be related to
the impact that created Odysseus.
* Hyperion's elliptical orbit and irregular shape influence its
chaotic tumbling, which may have started after a giant impact
with
another body.
