Abstract <p>The article considers a variant of the lunar transportation system using an orbital station deployed in a stable high circumlunar orbit. The insignificant size of the Moon’s gravisphere, in terms of planetary scales, allows us to consider the problem of near-lunar maneuvers in a new way. Rational use of gravitational perturbation from the Earth during flight in the boundary vicinity of the Moon’s gravisphere, reduces the cost of spacecraft delivery from the Earth to a high lunar orbit, where it is proposed to place the lunar orbital station. This approach is called the “gravispheric” effect, which is particularly well manifested in flights to high lunar orbit. The paper presents a mathematical description of the gravispheric effect and examples of its use in transfers between the Earth and high lunar orbit obtained by the authors.</p>
