We invite for this session papers on the results of past or present planetary missions on the Martian Moons, and on Phobos in particular. A special emphasis will be given to the January 2011 Mars Express flyby. The following topics can be addressed: position and ephemerids, interior, mass determination, gravity field, subsurface, surface properties, temperatures, composition, geology, shape and volume, origin of the moons, solar wind interaction. Papers on the future mission Phobos-Grunt and on ideas for new missions (in-situ, sample return, manned missions) are welcome. Ground-based observations results are also relevant.
