Martian landscape. This HiRISE image shows a crater in the Tyrrhena Terra region and a set of star dunes visible on the western edge of a small crater within the larger target crater. Star dunes form when sand is blown by winds coming from multiple directions, common in craters. This results in intersecting dunes, forming a polygonal, or 'star' pattern. The dune sands are most likely made of basalt. Possible clay-bearing material is probably within the surrounding bedrock. Image shows terrain less than 5 km (3 mi) across. A unique optimised version of NASA imagery. Credit: NASA/JPL/UArizona
