Chaos on Mars
Click for full image.
The Mars Express science team today released a digital perspective view of the chaos terrain located in the outlet region for the vast drainages, which include Marineris Valles, coming down from the Tharsis Bulge volcanic region that holds Mars’ largest volcanos.
The view, reduced to post here on the right, was created from a image taken by Mars Express on October 31, 2018. This chaos terrain is south of the various examples of chaos terrain previously highlighted here on Behind the Black (May 14, 2018, June 26, 2018, March 11, 2019, March 14, 2019). As they note,
The division between the chaotic terrain and plains can also be seen clearly in these images. The left (south) side of the image is notably smoother and more featureless than the jumbled right (north) side, and the two regions are split by a prominent line carving diagonally across the frame. The transition area around this scarp is especially broken and fractured; this is thought to be caused as the martian crust stretched and moved.
…
The ancient chaotic terrain we see on Mars holds information about how water once permeated and interacted with the planetary surface, including how it was transported, stored, and released.
Chaotic terrain is thought to have formed as chunks of the martian surface collapsed in dramatic events triggered by the heating of material containing ice or water-bearing minerals – possibly due to climatic or volcanic heat sources, or an impact from an asteroid or comet. This released large amounts of water, causing the terrain above to subside. The water then drained away quickly, leaving behind the messy, broken patterns seen in regions such as Aurorae Chaos, which is thought to have formed some 3.5 billion years ago.
Mars Express images don’t quite have the resolution of the high resolution images from Mars Reconnaissance Orbiter, but they cover a wider area, so that the spacecraft has now photographed almost the entire Martian surface since its arrival in Mars orbit in December 2003.
