When the Cassini spacecraft arrived at Titan in 2004, it revealed a varied and active world previously unseen. Unique among the icy satellites, Titan’s surface shows evidence for extensive modification by fluvial and aeolian processes. Erosion likely contributes to the noticeable lack of craters on Titan, complicating age dating of its surface. Indeed, many of the craters that have been identified on Titan’s surface appear to be altered by fluvial erosion, mass wasting, burial by dunes and/or submergence in seas.
