  • Results of the boundary value problem solution for determining the trajectory of returning from the lunar orbit and landing on the Vostochnyi launch site are presented. The solution includes the calculation of the required expenditure of the characteristic velocity for forming the return trajectory and an estimate of the correction impulses for ensuring the required condition of the atmosphere entry. As the descent module moves in the atmosphere, the terminal guidance algorithm developed earlier is used; this algorithm realizes a skip entry trajectory. Results of the statistical simulation of descent trajectories in the disturbed atmosphere for the real-life condition of returning from the Moon are presented. It is shown that, in the case of perfect navigation and load factors of about five, the accuracy of the descent module guidance to the Vostochnyi landing site within 2 km can be achieved.
