The orbit of the Earth has become a great place for the disposal of debris. For the period December 29, 2004 the U.S. Space Observation Network USSTRATCOM fixed object in orbit 9233, most of them — it's part of the missiles. It is fully spent or nearly dead aircraft, engines, panels and rocket stages, pieces of rocket fuel, insulation and paint flakes, thousands of icy chunks still radioactive coolant brand plucked out of Russian satellites.
At the completion of the orbital landfills contribute the largest share of sudden collapsing objects, due to an oversight when there is a mixture of fuel and oxidizer, when the remnants of fuel are under great pressure due to the heat, or when there is an explosion of batteries on board. Some aircraft exploded on purpose. It can cause an explosion collision with debris traveling at high speed, the edition notes.
This month orbital dump by a pair of U.S. missile stages and Russian engine "Proton". Occasionally individual objects survive even after passage through the atmosphere. Last year in Argentina was found a piece of titanium plating 70 kg, which was part of the third stage Delta 2 rocket, which was in orbit since October 1993.
But, according to the American newspaper, it's all — nothing compared to the huge object that moves by itself — an orbital telescope Hubble, which may soon be written off. The uncontrolled fall back to Earth Hubble may represent a great danger to people. According to analysts, the risk to the public from falling Hubble in 2020 would be 1:250, higher than the safety standard NASA. At least two tonnes of material will fall from space observatories. As a result, space debris is scattered over the territory of 1,220 km, the newspaper writes.
