Abstract :
In paper it is investigated the control laws optimization and suited low thrust trajectories in the Earth-Moon system in limited three-body problem. With Pontryagin principle of maximum necessary conditions of optimum control laws for variable optimal criteria - the minimum mission duration and the minimum fuel consumption are found. For variable boundary conditions transversal terms are obtained and appropriate boundary problems are formulated. It is suggested approach of initial approximation choices for boundary tasks. It is given results of numerical modeling.
