Scientific paper
In February and March 1989 the Phobos 2 spacecraft took 37 television images of Phobos from a distance of 190-1100 km. The data are being used to update the three-dimensional model of Phobos, to provide improved determinations of its density and orbital dynamics, and to study its surface color, composition, and texture. Preliminary findings are presented here which include different integrated photometric behavior in visible and near-infrared bands, observation of a region immediately west of Stickney which is relatively free of large grooves, the prevalence of bright rims on grooves and younger craters, and low bulk density.
