Anaglyph image of a crater south-east of Serpentis Terra
Anaglyph images can be created from the nadir channel of the HRSC camera system operated by DLR on board the ESA Mars Express spacecraft, which is directed vertically onto the surface of Mars, and the oblique view from one of the four stereo channels. When using red-blue or red-green glasses, they provide a realistic, three-dimensional view of the landscape.
The spatial view reveals the morphology of the four-kilometre-deep and 50-kilometre diameter ‘crater bowl’ in excellent detail, but also smaller structures such as a small dune field inside the crater and gullies and valleys in the crater rims. Strikingly, in the 3D view, the edge of a terrain emerges about 10 kilometres from the edge of the crater, formed by retrogressive erosion of the ejecta blanket deposited during the formation of the crater.
