Mars Express acquires sharpest images of martian moon Phobos

On 23 July 2008, the High Resolution Stereo Camera on board the ESA’s Mars Express took the highest-resolution full-disc image yet of the surface of the moon Phobos. The image data was acquired from a distance of 97 km with a spatial resolution of about 3.7 m/pixel in orbit 5851. These images have surpassed all previous images from other missions in continuous coverage of the illuminated surface at the highest spatial resolution of 3.7 m/pixel. This image has been geometrically corrected and exhibits the original illumination and photometric conditions. Credits: ESA/ DLR/ FU Berlin (G. Neukum)
