This colourful image resembles an abstract watercolour, but it is in fact a colour-coded topographic map of one of the most geologically diverse regions on Mars. The images featured in this release were taken by the high-resolution stereo camera on ESA’s Mars Express on 10 November 2014, and focus on Tempe Fossae in the Ascuris Planum region of Mars.
Situated at the northeastern edge of the Tharsis volcanic province, this region is found close to the transitional zone between the ancient southern highlands and the young northern lowlands. It is characterised by a large variety of tectonic and volcanic structures with ages that span much of the Red Planet’s geologic history. [More at link]
