This image of a Martian landscape was taken by the European Space Agency's Mars Express spacecraft in May 2004. It shows an area in the Promethei Terra region, which is relatively smooth, but covered with a layer of dust or volcanic ash several tens of metres thick. This layer has covered everything, and obscures fine details; that's why the picture looks a little fuzzy. The crisscrossing lines across the picture are the tracks left by dust devils.
