The conducted researches are directed on the solution of one of the most important problems of the space use – a problem connected with existence and inadmissibility of growth the quantity of a technogenic origin space debris on low near-earth and geostationary orbits because its further increase will overlap to mankind an exit in space and will terminate space activity. In the basis of a technique of researches the analysis of an existing ecological condition of the surrounding space environment on which base determined the major factors of pollution of the space and considered ways of struggle against space debris on near-earth orbits is put. It is established that the major factors of pollution of the near-earth space are spent stages of launch vehicles and accelerating units, the space crafts which have terminated its existence, fragments of destroyed artificial space objects, operational elements etc. Space debris basically is concentrated on low orbits and around a geostationary orbit which on the basis of the analysis of statistical data on space crafts starts are in most common use. Here groupings of space crafts of the various particular mission, including space crafts of communication, relay, TV, the early prevention of a rocket attack are concentrated. It is shown that the main ways of struggle against space debris are prevention of occurrence new and removal of the already existing debris. Notable decrease in level of the pollution can achieve at cumulative use of such measures, as an exception of explosions of the space objects, limitation of quantity of the started space crafts, reduction of number of the accompanying fragments injected into orbits at starts. Methods and means of withdrawal from working orbits of space crafts upon termination of term of their active existence and known ways and systems of active removal of already existing fragments of the space debris, such as: application of an ionic bunch, the space ship-towing vehicle, the polyurethane foam, the pulsing laser, harpoon system, electrodynamic cord system are considered. Scientific novelty of the presented results consists in the description of conceptual actions for reduction of pollution of the space. The activities executed in the given direction, have huge practical value as the outer space exploration gives huge advantage and significant progress to mankind, but the further operation at near-earth space by existing methods without acceptance of the measures indicated in the article, its further safe development already will not allow in the near future.
