The Colour and Stereo Surface Imaging System, CaSSIS, onboard the joint ESA-Roscosmos ExoMars Trace Gas Orbiter imaged the Ariadne Colles region at 34°S on 2 September 2018.
The image shows an unusual terrain type – sometimes referred to as chaotic blocks – but what is particularly striking are the large number of dark streaks. One possible interpretation is that these features were produced during the recent dust storm: they could have resulted from dust devils stirring up the surface dust.
