Draped Dunes -- 3D (IMAGE) University of Bern Caption This image shows dust dunes cascading over the edge of Green Crater, in the Noachis Terra region of Mars. Dunes on Mars are dynamic features, observed to move at speeds of up to 5 m per martian year. Dust devil streaks -blue in this colour-composite representation -- are seen on the interior wall of the crater. Use red-blue stereo '3D' glasses to best enjoy this view of dust dunes.
