Moons of Mars

Mars Express closed in on the intriguing martian moon Phobos at 6:50 CEST on 23 July, flying past at 2.96 km/s, only 100 km from the centre of the moon. The ESA spacecraft’s fly-bys of the moon have returned its most detailed full-disc images ever, also in 3-D, using the High Resolution Stereo Camera on board.

The images obtained by several other spacecraft so far have either been of a lower resolution, or not available in 3D and have not covered the entire disc of Phobos. This is also the first time that portions of the far-side of the moon have been imaged in such high resolution
