Mawrth Vallis has a rich mineral diversity, including clay minerals that formed by the chemical alteration of rocks by water. The CRISM instrument detects a variety of clay minerals here, which could signify different processes of formation. The high resolution of the HiRISE camera helps us to see and trace out layers, polygonal fractures, and with CRISM, examine the distribution of various minerals across the surface.
This surface is scientifically compelling for the MSL rover, although some of the terrain can be somewhat rough. Scientists use HiRISE images to find the safest possible landing site for the rover.Written by: Jennifer Griffes (4 June 2008)
