Zooming in reveals a number of boulders which have fallen from the cliff edge, leaving small dimples within the mushy materials as they tumbled down-slope.
The picture was taken by the CaSSIS digicam onboard the ESA/Roscosmos ExoMars Hint Fuel Orbiter on August 3, 2020, and captures a slice by way of the maze-like system of the aptly named Noctis Labyrinthus. The cliff-like characteristic operating by way of the central portion of the picture is a part of a horst-graben system, which contains raised ridges and plateaus (horst) both aspect of sunken valleys (graben) created because of tectonic processes that pulled the planet’s floor aside. Your complete community of plateaus and trenches making up Noctis Labyrinthus spans some 1200 km, with particular person cliffs reaching 5 km above the floor beneath.
Elsewhere on this picture and specifically in the direction of the right-hand aspect are patches of linear ripples which have been formed by the wind. A number of small affect craters additionally pockmark the scene.
The picture was taken over the easternmost a part of Noctis Labyrinthus at 265.8°E/8.70°S within the Phoenicis Lacus Quadrangle, close to the intersection with Lus Chasma of Valles Marineris – the ‘grand canyon’ of Mars.
TGO arrived at Mars in 2016 and commenced its full science mission in 2018. The spacecraft will not be solely returning spectacular photos, but additionally offering one of the best ever stock of the planet’s atmospheric gases, and mapping the planet’s floor for water-rich places. It can additionally present knowledge relay companies for the second ExoMars mission comprising the Rosalind Franklin rover and Kazachok platform, when it arrives on Mars in 2023.
