ESA – The two faces of Titan’s dunes




Dunes on Titan and Earth
 
Two different dune fields on Titan: Belet and Fensal, as imaged by Cassini’s radar. It also shows two similar dune fields on Earth in Rub Al Khali, Saudi Arabia. Fensal is at higher latitude and elevation than Belet and clearly shows thinner dunes with brighter and wider areas in between, suggesting less abundant dune material in this region.Data from NASA’s Cassini spacecraft show that the sizes and patterns of dunes on Saturn’s moon Titan vary as a function of altitude and latitude.
