Improvement of the surface shape model of Phobos
Improvement of the surface shape model of Phobos
These slightly different images were acquired by five different channels of the High Resolution Stereo Camera (HRSC) during 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). The fact that another area of the moon’s surface can be seen in every image at a slightly different viewing angle allows the model of its surface shape to be improved.
