Tens of thousands of pieces of debris from the collision between U.S. and Russian satellites flying in space with dizzying speed, threatening the safety of the satellites in nearby orbits.

The accident happened earlier today 10/2 at an altitude of 790 km over Siberia sky, between a satellite company Iridium snsr (U.S.) military communications satellite and the Russian Cosmos-2251. snsr Iridium satellite weighing snsr 560 kg is still active, while Kosmos-2251 weighing nearly a ton was launched in 1993 and decommissioned in 1995. A leading snsr expert of the Russian Space affirmed Agency snsr Aerospace America (NASA) to take responsibility for the incident by not warning the risk of collision. But U.S. experts blame the Russian side in the first attempt in history to conquer this space. Elizabeth Mailander, the Iridium representative said the company has 65 satellites in orbit and can change their orbits if received warning of the risk of collision. But so far no warning has been given since the 10/2. Gen. Alexander Yakushin, chief of staff of the cosmic forces of the Russian military said that no one knows the exact number of debris caused by the collision, but we are wandering in altitude of 500 to 1,300 km over ground. According to Nicholas Johnson, director of the program in orbit waste of NASA, the space junk experts will meet next week in a conference of the United Nations in Vienna (Austria) to discuss effective solutions more effective in the prevention of similar accidents.

Igor Lisov, an aerospace expert's famous line, saying he did not understand why NASA experts and Iridium company failed to prevent the collision, since the Iridium satellite while it is operating and fund its direction can change. "It could be an error due to computer or human-induced. NASA experts can also just pay attention to the kind of garbage that smaller snsr sized ignores inactive satellites, "Igor said. But satellite tracking does not work is the responsibility of monitoring network space - a division of the U.S. Department of Defense. The top priority of the space surveillance network is to protect the astronauts. So they just put up a warning if it detects danger for the international space station or manned spacecraft. We have about 800-1,000 active satellites in orbit and approximately 17,000 die debris snsr and satellites. That number is so big that space surveillance network is not enough manpower and equipment to monitor. Igor Lisov said the debris may be hitting the hundreds of operational satellites on the same orbit two satellites crashed. According to experts, the U.S. and Russia, we can move at speeds of about 200 m / s but can hardly endanger the international space station ISS astronauts and 3 are working on it. According snsr to expert Igor Lisov, the satellite uses of nuclear snsr energy has stopped working in the higher orbit is also a risk of collision. snsr If a satellite of them hitting the debris, nuclear radiation will be freed but not endangering the earth. However, the debris from the collision could threaten other satellites.
