High-Resolution Stereo Camera nadir and colour channel data taken during orbit 11467 on 4 January 2013 by ESA’s Mars Express have been combined to produce this colour view of two craters, both roughly 50 km in diameter. The data were acquired in the Thaumasia Planum region just south of Vallis Marineris at approximately 17°S / 296°E and have a ground resolution of approximately 25 m per pixel. The northern (right) crater is named Arima, while the southern (left) crater is unnamed. Both large craters sport central pit features.
A perspective view of a 50 km diameter crater in Thaumasia Planum. The image was made by combining data from the High-Resolution Stereo Camera on ESA’s Mars Express with digital terrain models. The image was taken on 4 January 2013, during orbit 11467, and shows a close up view of the central ‘pit’ of this crater, which likely formed by a subsurface explosion as the heat from the impact event rapidly vapourised water or ice lying below the surface.
This colour-coded overhead view is based on an ESA Mars Express High-Resolution Stereo Camera digital terrain model of the Thaumasia Planum region on Mars at approximately 17°S / 296°E. The image was taken during orbit 11467 on 4 January 2013. The colour coding reveals the relative depth of the craters, in particular the depths of their central pits, with the left-hand crater penetrating deeper than the right (Arima crater).
Part of the Thaumasia Planum region imaged during revolution 11467 on 4 January 2013 by ESA’s Mars Express using the High-Resolution Stereo Camera (HRSC). Data from HRSC’s nadir channel and one stereo channel have been combined to produce this anaglyph 3D image that can be viewed using stereoscopic glasses with red–green or red–blue filters. Centred at approximately 17°S / 296°E longitude, the image has a ground resolution of about 25 m per pixel. The image highlights the Arima crater (right) and its unnamed ‘twin’ crater to the left, and the central pit features of both craters.
