The DLR-operated High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft acquired images of Phobos on 9 January 2011 from a distance of just 100 kilometres with a resolution of 8.1 metres per pixel. Due to the stereo viewing geometry during the flyby, a small part of the moon's edge is only visible to the right eye, resulting in odd 3D-perception in this area. This part has been adjusted slightly for better viewing. For the left eye, four small data gaps at the left edge of the image have been interpolated.
Data from the nadir channel and one stereo channel was used to produce this 3D image. Stereoscopic glasses are required to see the 3D effect.
