This image of Phobos’s surface was obtained by the Super Resolution Channel (or SRC, a part of the High Resolution Stereo Camera experiment) on board ESA’s Mars Express on 3 August 2008 (orbit 5889). The distance from the moon’s centre was 656 km, and the image resolution is 6 m/pixel. The original image has been corrected for mirror distortion. Credits:
