Traces of water in one
of the biggest valleys on Mars
With a length of 600 kilometres and a depth of up to two kilometres, Mawrth Vallis is one of the biggest valleys on Mars and a possible landing site for the ESA ExoMars and NASA Mars 2020 missions. It is entrenched in the Arabia Terra highland, which is more than four billion years old, and ends in the great Chryse Planitia lowland region.
The image shown in this article covers an area of around 330,000 square kilometres on the transition from the southern Martian highlands to the northern Martian lowlands. Mawrth Vallis is at the centre of the image. The image shows a bird’s eye view of the region – the perspective from which the High Resolution Stereo Camera (HRSC) on board the European Mars Express spacecraft has been observing the surface of Mars since 2004. It creates image strips that are around 200 to 500 kilometres wide and several hundred to thousands of kilometres long (depending on the altitude of Mars Express). This view of the region around Mawrth Vallis was made possible using a mosaic of nine individual HRSC images. The camera is operated by the German Aerospace Center.
