Analysis of spatial-temporal distribution of the anthropogenic substances flux density in the Near-Earth Space

The task of ensuring safe operation of the orbital stations in conditions of the Near-Earth Space increasing pollution with the so-called space debris became especially significant in the International Space Station development. In addition, space debris poses a certain danger to spacecraft currently in operation. To assess the degree of risk, this paper presents a relational database developed by the authors making it possible to determine the number of the space debris particles collision and the impact parameters (particle size and collision speed) on the spacecraft staying in different orbits. Calculations in this case made it possible to determine potential number, probability of collisions and parameters of the space debris impact interaction with a group of small domestic spacecraft.
