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.
