Annual meeting of the leaders of the scientific groups involved into the International project IMPEx - Integrated Medium for Planetary Exploration took place at SINP MSU. IMPEx is based on the database on the magentic fields and plasma in the magentospheres of the Solar system's planets compiled by means of operated on-orbit spacecrafts and the results of computer simulation. Four scientific groups (from Russia - consisting of the SINP scientists, Austria, Finland and France) participate in the IMPEx project.
