The colour-coded topographic view shows relative heights and depths of terrain in the Terra Sirenum region of Mars focusing on a ‘triple crater’. As indicated in the key at top right, whites and reds represent the highest terrain, while blue/purple is the lowest.
The image is based on a digital terrain model of the region, from which the topography of the landscape can be derived. This region was imaged by the High Resolution Stereo Camera on ESA’s Mars Express on 28 January 2017 during orbit 16565. The image is centred on 198°E / 27°S and the ground resolution is about 22 m per pixel. North is to the right.
