The largest of the cronian moons Titan present an active methane cycle in its atmosphere reshaping continuously the surface in a wide varity of terrains, similarly to the water cycle on Earth. For 13 years Cassini’s spacecraft has studied Titan and its RADAR has imaged the surface while recording its thermal emission. Using the complete active and passive microwave data, we have detected several traces of fluvial and lacustrine activity that indicates that the austral hemisphere used to be moister than its actual state, and we try to understand the processes that formed the austral polar landscapes.
