Abstract
The article discusses the possibilitу of using the Lagrangian points (libration points ) in outer space ‒ starts of rockets, spacecraft for various purposes, emergencу situations, disposal of space debris. The advantages and expediency of placing spacecraft at some points of librations in the system "EarthMoon" are shown. When the system is at Lagrange points L1, L2, L3, the system is unstable, the Lagrangian points L4 and L5 ensure the stability of the system. With external perturbations, the body at points L1, L2, L3 will tend to escape from these points, and the body in points L4, L5, with external disturbances, will tend to return to these points, or make oscillatory movements near them. For the creation of a large inhabited station in the Moon's orbit, in connection with the foregoing, the libration points L4, L5 located 60 degrees ahead of the Moon are suitable. In Ukraine, work in this conducted a systematic way and in CB "South" there is a program for the development of the Moon with the placement of the modules on the Moon, and on its orbit. The main problems of the world cosmonautics that require urgent solutions are identified: this is an technogenic clogging of outer space and an asteroid hazard for the planet Earth. An analytical expression is obtained for the Lagrange function of a free particle of outer space, which can be represented as a fragment of space debris. The main directions of research related to the utilization of space debris are determined, the features of using the libration points for this purpose in the system "Earth-Moon" are shown.
Keуwords: libration points, Lagrangian points, space vacuum, halo-orbit, moonorbit, space debris, Kessler effect, asteroid danger, "Earth-Moon" system, Lagrange function.
