Kurzfassung
Ithaca Chasma is the most prominent tectonic feature on Tethys (R~530 km). It was first seen in Voyager I images as an enormous valley about 1000 km long and 50 to 100 km wide. The origin of this rift valley is not clear yet. Smith et al. (1981) suggested that Ithaca Chasma was formed by freeze-expansion of Tethys' interior but other models relate Ithaca Chasma to the formation of the 400 km Odysseus impact basin. Photoclinometry was applied to infer the topography of Ithaca Chasma. An average depth of ~3km was obtained and a raised rim of ~ 0.5 km above its surroundings was found. However, low image resolutions (Voyager I: 15 km/lp at best, Voyager II: 5 km/lp at best) have prevented in-depth morphologic studies. In this paper we report on the topography of Ithaca Chasma derived from high resolution Cassini-stereo images.
