a Coverage and geometric (spatial) resolution of MIRS mapping from QSO-H in Oct 2025 (β = 10°). The resolution at equator is better than high latitude regions because QSO-H is on the equatorial plane. Areas in white cannot be observed because of spacecraft’s equatorial trajectory and Phobos flat shape on the poles. Areas with the spatial resolution above 200 m are not displayed. Note that the map was calculated without considering the masking of facets by local topology: areas with longitude around − 150° and 150° and latitude − 80° as well as the areas with longitude around 150° and latitude 80° are actually masked and cannot be observed. Percentage of surface covered at resolution better than 100 m is 98% for areas within ± 30° latitudes and 73% for all areas, at resolution better than 40 m is 28% for areas within ± 30° latitudes and 16% for all areas, and at resolution better than 30 m is 0% for areas within ± 30° latitudes and 0% for all areas. b Percentage of Phobos surface covered as a function of phase and sun incidence angles with observation in a. Blue lines indicate percentages for surface within ± 30° latitudes, while red lines for whole surface
