Use red-blue stereo '3D' glasses to best enjoy this view of circular depressions in the southern hemisphere of Mars, exposing layered outcrops in the northern rim of the large Hellas basin

The geology of the Hellas basin is complex with ancient terrains showing evidences of erosion and sedimentary processes, which might be linked to past water activity. Both the shapes of the features revealed by stereo imaging and the mineralogical composition of the finely layered outcrops are key for understanding their formation processes. CaSSIS colour-composite images like these, combined with data from other instruments, help map variations in composition of the surface material.

The image was created from a stereo pairs taken by the Colour and Stereo Surface Imaging System (CaSSIS) onboard the ESA-Roscosmos ExoMars Trace Gas Orbiter on 22 December 2018. The image is aligned from left to right along the ground-track of the spacecraft, and is centred at 29.2°S/66.8°E.
