(from the its-a-slow-market-news-day dept) According to TASS: "...the braking will begin only after the Mir's orbit falls to lower than 250 kilometres, which is expected to happen after March 8. This will save up fuel which is needed in case of emergency. In addition, this will allow specialists to execute "pinpoint" landing of the Mir. About 1,500 pieces of the station, weighing 12 tonnes, that will not burn in the upper layers of the atmosphere should fall in the South Pacific in an area 5,000 to 6,000 kilometers long and 200 kilometers wide. "Such operations have been carried out only twice before. In 1979, the U.S. station SkyLab was sunk. It was thought that the station, raised to a high orbit, will be able to operate for almost 100 years, but it began to fall rapidly. NASA tried to sink the station in the ocean and almost succeeded , as most fragments fell in the Indian Ocean southwest of Australia, but about 1,000 pieces landed in a populated farming area in Western Australia. Luckily, no one was injured. "The second case took place in 1991 when the Soviet station Salyut-7 was returning to earth. It was built to fly for decades but high solar activity and thickening atmosphere caused to fall. Its debris are believed to have fallen in Argentina but were never found. "We were lucky with the Salyut," Yuri Koptev, general director of the Russian Aircraft and Space Agency (Rosaviakosmos), said. "The Soviet Union was less lucky in 1978 when its military satellite lost control and fell in Canada. The Soviet government had to pay over six million U.S. dollars to Canada in compensation . But neither the two stations nor the satellite, each of which weighed several times less than the Mir, can compare with the upcoming operation. It will be an unprecedented endeavour in terms of technical complexity. But Koptev says that the Mir should "go as nicely as it came" into world aeronautics. --- [Ok, I'll buy that! LOL. So two intentional space station decomissionings have failed, the Russions feel "lucky", and unplanned failures haven't hit anyone. Yet. PS: The Russion military satellite dropped nuclear debris on Canada...]
