The European Space Agency (ESA) has released a new image of Mars showing signs of “geological movement” on the red planet. This image is the first version for 2022 and was taken on 3 August 2020 by the CaSSIS camera on the ESA/Roscosmos ExoMars Trace Gas Orbiter (TGO).
This spectacular image from TGO shows Noctis Labyrinthus, a large valley system at the western end of the Valles Marineris canyon system. It was taken over at the easternmost point of Noctis Labyrinthus at the Phoenicis Lacus Quadrangle, near the junction with Lus Chasma at Valles Marineris – the “Grand Canyon” of the Red Planet.
As described by ESA, the cliff-like features running through the central portion of the image are part of a horst-graben system that includes raised ridges and plateaus (grabens) flanked by tectonic depressed valleys (grabens) The process of pulling the surface of a planet apart. The entire network of plateaus and trenches that make up the labyrinth spans about 1,200 kilometers, with individual cliffs reaching 5 kilometers above the surface.
Zooming in on the picture shows several boulders falling off the edge of the cliff, leaving small pits in the soft material as they tumbled down the slope.
