The changing face of Titan

Highly Allochthonous : Remember when we could only guess what lay beneath Titan’s thick atmosphere? Thanks to Cassini and the Huygens lander, things are very different now. We have had a surface both strange and strangely familiar revealed to us, with mountains, rivers and lakes shaped by the flow of liquid ethane, and dunes of hydrocarbon sand. Furthermore, multiple flybys by Cassini in the past 5 years has allowed long-term monitoring of the surface, with consecutive observations of the same region enabling us to chart the evolution of Titan’s surface over time. Some recent publications in Geophysical Research Letters have spotted some rather interesting changes.
