Space debris is a collection of man-made objects and their fragments in space, which no longer function and serve any useful purpose. Besides, space debris includes objects of natural origin, such as meteorites, asteroids, etc. Thus, we can single out several categories of space debris: (i) Spent upper rocket stages and detached stages; (ii) Old satellites; (iii) Products of anti-satellite tests and debris formed due to collisions of satellites; (iv) Objects of natural origin. DANGEROUS STRANGERS Most space debris includes small fragments less than 10 cm in diameter. The most significant contribution to the 'littering' of the near-Earth orbits have been made by anti-satellite missiles used to destroy worn-out satellites, which led to the formation of new fragments measuring from centimeters to several meters in size. Explosions and unintended collisions in space are the most dangerous sources of space debris [1-4]. One of the first victims of the space debris was the crew of the shuttle Challenger in 1983, when the spacecraft collided with a small-size particle (less than 1 mm in diameter); as a result, there appeared a crack in the porthole. Later, the experts concluded that it was a microscopic particle of paint detached from some spacecraft. The Soviet space station 'Salyut-7', which was also hit by microscopic particles, continues the list of victims of space debris. The Russian space station Mir whose solar battery was punched in the 1990s by a piece of space debris, which resulted in a 'hole' of more than 10 cm in diameter, was no exception. Now the International Space Station (ISS) can maneuver to avoid possible collisions with space debris (this year it has been already done seven times), but the safety of the station is still the main concern to the experts. Thus, in 1999 the ISS nearly ABSTRACT Studies show that the number of debris in Low Earth Orbit is exponentially growing despite future debris release mitigation measures considered. Especially, the already existing population of small and medium debris is today a concrete threat to operational satellites. Ground based DFlaser solution which can remove at low expense and in a non-destructive way hazardous debris around selected space assets appears as one highly promising answer. SSL with LD pumping based on space vehicle as an additional solution is under consideration in the paper.
