After half a century of space debris would threaten Russia’s national security – BBC

Order 750 million artificial objects can be located on the Earth’s orbit, while Russian experts see only about 17 000 thousand. Of these, only 1,361 thousand. are operational spacecraft, while the remaining part is a space debris, said TASS the press service of the head of the Institute of the Russian Space Agency – the Central Research Institute of Mechanical Engineering.

«As of July 31, 2015 the total amount being in outer space and cataloged in databases automated warning system on dangerous situations near-Earth space space objects technogenic origin was 17.141 thousands of space objects, including 1,361 thousand – is operational spacecraft, the remaining 15.78 thousand – Space debris “, – reported the press service.

« The problem of fighting with space debris becomes extremely relevant. It can be formulated in a sufficiently categorical terms: in the coming decades will not be a transition to the new technology of operation rocket and space technology to prevent space debris, then after 50-60 years, the level of clogging of near-Earth space can significantly hinder further space activities that can a negative impact on many aspects of state activity and pose a threat to the national security of Russia “, – reported in TsNIIMASH.

In this orbit can be more than 750 million objects larger than one mm. Of these, 4.5 million more than one cm, 22.7 thous. Of objects – more than ten cm. As explained in the press service, the data follow from the domestic model of space debris Space Debris Prediction and Analysis, developed by a professor, a member of the international committee on the issue debris Andrei Ivanovich Nazarenko.

Earlier reports , that the International Space Station successfully passed a collision with space debris.
