Longitudinal dunes on Titan

Longitudinal dunes on Titan
Longitudinal dunes on Titan When Cassini acquired this SAR image of Titan on October 28, 2005, it was flying east-west, illuminating Titan with a radar beam shining toward the south. The bright streaks in this image are interpreted to be the north-facing slopes of linear sand dunes, reflecting the radar beam back at Cassini. The dunes are very large, spaced roughly 2,000 meters apart and stretching for tens of kilometers. This image covers an area about 180 by 56 kilometers (112 by 35 miles), located about 10 degrees south of the equator in a dark region known as Belet. NASA / JPL-Caltech
