Figure 81: 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 image was created from a stereo pair taken by the CaSSIS instrument onboard the ESA-Roscosmos ExoMars TGO on 22 December 2018. The image is aligned from left to right along the ground-track of the spacecraft, and is centered at 29.2ºS/66.8ºE (image credit: ESA/Roscosmos/CaSSIS, CC BY-SA 3.0 IGO)
