Light and dark coloured crater landscape in Terra Cimmeria
Light and dark coloured crater landscape in Terra Cimmeria
This image, acquired on 11 December 2018 by the HRSC camera experiment developed and operated by the German Aerospace Center (DLR), shows part of the Terra Cimmeria highland region on Mars. The large crater in the centre of the image was probably formed over three billion years ago. This can be seen from the strong weathering of the crater rim and the almost complete filling and levelling of the originally bowl-shaped crater structure by sediments. Bright and very dark areas are clearly visible. The striking light-dark shades are caused by differences in the mineralogy of the surface material. North is to the right of the image.
