A new analysis of radar data from the international Cassini spacecraft has revealed regional variations amongst Titan's sand dunes. The result yields new clues to the giant moon's climatic and geological history.
Dune fields are common on Titan, the largest moon of Saturn, second only to the seemingly uniform plains that cover most of the surface.
They cover about 13% of Titan, stretching over 10 million sq km, roughly equivalent to the area of Canada. Thus they offer a large-scale insight into the moon's environment.
