HRSC images from Mars Express Phobos flybys are
used to study the photometric character of the surface
of the Martian satellite. This investigation involves
measuring of surface reflectance and illumination
angles for estimates of a phase curve, and fitting of
theoretic photometric functions. As results we obtain
information on multispectral and physical properties
of the Phobos surface as well as photometrically
corrected geomorphological and albedo maps
