M. : University Book, 2009. - 104 s. The manual highlights the current state and prospects of research on the impact of meteoric matter and solids of artificial origin (“space debris”) on spacecraft. The manual provides information about meteoric matter and space debris in near-Earth space, Models and standards , used to determine the parameters of body flows of natural and artificial origin , Physical phenomena , High-Speed Impact , methods and technical means of laboratory modeling of high-speed collisions and studying them in space experiments are described , Methods of protection of spacecraft. This manual is a revised and supplemented manual by the author on this topic "High-speed collisions in space", published in 2003. The proposed manual includes new data on the problem under consideration, Over the last six years, as well as data on the effects of meteor particles, secondary particles of lunar soil and dust streams, significant hazard to the apparatus, Orbits of the Moon, and future structures on the surface of the Moon. The manual is intended for students and postgraduates of higher educational institutions, as well as for use in retraining of personnel in new promising areas of science and technology .
