Since the VSOP87 algorithm computes the position of all the planets (Earth included) relative to the barycenter of the Solar System, it's relatively easy to shown the sky as it would be observed from another planet and with similar accuracy to Earth based observation. Some inaccuracy may creep in with values of the obliquity of the ecliptic and longitude of the vernal equinox for the individual planets, since these are not known with great accuracy or how they change with time.
Click on the Observer menu in the main menu, to see these options. Mars has a time reference system defined for it, and this is implemented. Other planets are less well developed (some don't even have a solid surface and the rotational period is not accurately known), so less options are available.
