These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, are Europe’s highest-resolution pictures so far of the Martian moon Phobos.
The image collection shows Phobos in different orientations as seen from orbits 748, 413, 649, 682 and 715 (from clockwise from lower left), while the picture on the lower right is a mosaic made from the Super Resolution Channel on orbit 413.
The images have been derived from the HRSC nadir (vertical view) channel (except the mosaic from the HRSC Super Resolution Channel).
