By the Earth is flying out of control object

With such a forecast made by the experts of the American and European space agencies. Experts of the German Aerospace Center suggest that this will occur in the period from 21 to 25 October. But no one has been taken to tell exactly where the debris will fall, according to ITAR-TASS. The possible impact area extends from Berlin and Samara in the north to Tierra del Fuego archipelago in the south.

We only know that the atmosphere will not have time to burn about 30 pieces of German design space telescope weighing up to 1.7 tons. The exact point of impact can be called only for an hour or two before it happens. Likely death is 1 in 2000, the website of the newspaper "Trud".

"On entering the atmosphere this machine can not even finish a regular orbit around the planet. Begins its free fall ", — said the head of the Department of space debris Heiner Klinkrad.

In this case, according to RIA Novosti, the mirrors and instruments X-ray telescope have powerful protection from overheating and therefore can survive heat in the atmosphere during the fall. According to estimates of German specialists, X-ray optics, mirrors and their support of carbon may be the most severe of debris have reached Earth.

Yet this is not the only problem that threatens our planet. According to the weekly "World News" in Earth orbit now flies almost fifty nuclear satellites that could at any moment fall to the ground. 36 of them ran the USSR, 13 — U.S.. But between the Soviet and U.S. satellites have a significant difference. The fact that the Soviet Union used to fuel the satellite 235, and the U.S. — plutonium-238.
To date, plutonium-238 is the most dangerous of all known chemicals. Inhalation of one-tenth of a gram of the substance leads to pulmonary edema and death within a few days. Moreover, the process is irreversible.

A completely different picture is observed in the fall of the Soviet satellites with uranium-235. The destruction of the Soviet satellite can be compared to a small accident at the nuclear power plant. In close proximity to the crash site can receive low doses of radiation. Die from this almost impossible, whereas in case of a fall of a single American satellite only die from pulmonary edema can up to 300 thousand people.

Peak "sputnikopada" will begin in 2013, and then will only gain momentum. The fact is that when a burst of solar activity increases the density of the upper atmosphere, causing the satellites are beginning to slow. This is especially dangerous now that many have already fallen satellites into low orbit and may fall on the head of humanity at any time.
