This video visualises a flight over the eastern part of Noctis Labyrinthus as seen by Mars Express’s High Resolution Stereo Camera (HRSC). It presents a perspective view down and across this fascinating landscape, showing distinctive ‘graben’ – parts of the crust that have subsided in relation to their surroundings. The intense volcanism in the nearby Tharsis region is to blame for the formation of these features; this volcanism caused large areas of martian crust to arch upwards and become stretched and tectonically stressed, leading to it thinning out, faulting and subsiding.
The highest plateaus seen here represent the original surface level before chunks of surface fell away. The intersecting canyons and valleys are up to 30 km wide and six km deep. In many places, gigantic landslides can be seen covering the valley slopes and floors, while other valley slopes show large dune fields created by sands blown both down and upslope by martian winds.
