Arsia Chasmata

A 25 km-wide image strip over a structure called Arsia Chasmata, which lies on the flank of the large volcano Arsia Mons. The formation is volcanic in origin and many pit craters, possibly caused by subsidence, can be seen.

The image was taken on 22 November 2016 and is one of the first acquired by the Colour and Stereo Surface Imaging System (CaSSIS) onboard the ExoMars Trace Gas Orbiter. The image was taken as part of an eight-day campaign to test the science instruments for the first time since arriving at the Red Planet on 19 October.
