Korolev Crater, first image of Mars from ExoMars TGO (4K)

The Colour and Stereo Surface Imaging System, CaSSIS, onboard the ExoMars Trace Gas Orbiter (TGO) returned the first images of Mars. The image is assembled from three images in different colours, taken almost simultaneously on 15 April, and captures a 40 km-long segment of Korolev Crater, situated high in the northern hemisphere of Mars.
