The book presents in a systematic manner the dynamics of flight between the Earth and the Magnifier of spacecraft with high thrust engines (for example, chemical). First, for the bounded circular problem of three points, in which one attractive mass is significantly smaller than the other, an approximate method of point sphere of action develops. Further, these and more accurate methods consider three trajectory tasks: reaching the Moon, returning from the Moon to the Earth and flying around the Moon. Costs of characteristic speed required for flights between circular orbits of satellite and LIS along trajectories with two active sections are calculated (on computer). Solutions to problems and results of mass trajectory calculations are presented in a visible form suitable for practical use.
