Ballistic design of interplanetary missions for the spacecraft with electrorocket propulsion

The ballistic computations for the space missions' projects which purpose to use the space vehicles of the new generation are considered. The use of electrorocket propulsion will allow to reach some small bodies of the Solar System (asteroids, Mars saetellite Fobos, etc.) and to get the sample from them to the Earth. The goal of these missions is to get the new important data about creation of the Solar System. Contemporary methods of solving optimization problem and decomposition of the complex problem with analysis of plain model problems are used for ballistic design.
