Abstract:

Purpose. Our research is directed on the solution of one of the most important problems of the space use, a problem of space debris on the near-earth orbits.

Methodology. We have analysed the existing ecological condition of the space environment and defined the major factors of its pollution in order to find basic ways of reduction of space debris on near-earth orbits.

Findings. We have established that the major factors of pollution of the near-earth space are spent stages of launch vehicles and accelerating units, out-of-service space vehicles, fragments of destroyed artificial space objects, operational elements etc. Space debris is concentrated on low orbits and around the geostationary orbit. They are in most common use so they became the most polluted. The basic ways of the space debris reduction are prevention of further pollution and removal of the already existing debris. We have considered the methods and means of withdrawal of space craft from working orbits upon termination of their active utilization and known ways and systems of active removal of fragments of space debris.

Originality. We have described the conceptual measures of space pollution reduction.

Practical value. The described activities are of importance as the outer space exploration gives huge advantage and significant progress to mankind. But further operation at near space by existing methods without acceptance of the measures listed in the article can make its further safe development impossible in the near future.
