Wallpaper: Louros Valles - Universe Today
Here's a beautiful 1024x768 desktop wallpaper of a series of sapping channels on Mars called Louros Valles. On the right side of the image is the Ius Chasma canyon, which has dark deposits at the bottom that could be related to wind and water erosion (North is to the right in this image). The image was taken by the European Space Agency's Mars Express spacecraft at an altitude of 269 kilometres during its 97th orbit.
