Yes, the Phobos mission did return some useful data including images of Phobos
itself. The best I've seen had a surface resolution of about 40 meters. By
the way, the new book entitled "Mars" (Kieffer et al, 1992, University of
Arizona Press) has a great chapter on spacecraft exploration of the planet.
The chapter is co-authored by V.I. Moroz of the Space Research Institute in
Moscow, and includes details never before published in the West. Don't
know of any ftp sites with images though.
