Abstract

The article discusses the methodology and some results of optimization of the research mission in the near Sun space using gravity assists from the planets and low-thrust propulsion, in particular, electrojet propulsion system. A wide variety of options for the mission does not allow to seek a solution of the problem within a one class of ballistic schemes implemented by a single base space complex. Therefore, multicriterion optimization of the mission is proposed to carry out of the two-level scheme: first, within each class separately and then among competing variants.
