Mawrth Vallis region – the deepest clay deposits on Mars
New images, created using data acquired by the German Aerospace Center (DLR) High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show part of the dried-up Mawrth Vallis river valley. This is one of the largest and oldest valleys on Mars, where light-coloured clay deposits up to 200 metres deep can be found in numerous places.
