Phobos surface sequence

These five images were acquired using five different channels of High Resolution Stereo Camera during Mars Express orbit 17 342 on 12 September 2017: the nadir channel (centre image), the two photometry channels (left and right of the centre image) and the stereo channels (on the far left and right). A different area of the moon’s surface can be seen in each image from various viewing angles, allowing models of the surface and shape to be improved.
