Russian spacecraft carrying 3 Sats crashes !

An unmanned Russian rocket carrying three navigation satellites - worth US$200 million - has crashed shortly after lift-off from the Russian-leased Baikonur launch facility in Kazakhstan.There were no reported injuries.State-run Rossiya-24 television showed footage of the Proton-M booster rocket veering off course seconds after lift-off. It fell apart in flames in the air and crashed in a big ball of fire near the launch pad.Launch facility personnel who were in bunkers at the site when the rocket lifted off survived.Interfax said Kazakh emergency authorities were considering evacuating nearby towns in the sparsely populated area because of the potential health threat from toxic rocket fuel burning at the crash site.The estimated loss from the three satellites, meant for Russia's troubled Glonass satellite navigation system, was about US$200 million, Rossiya-24 reported. The state-run RIA news agency said the cause could have been a problem with the engine or the guidance system.Russia is increasing space spending and plans to send a probe to the moon in 2015, but the pioneering programme that put the first man in space in 1961 has been plagued in recent years by setbacks, including botched satellite launches and a failed attempt to send a probe to a moon of Mars. Sending a cloud of highly toxic orange fumes toward the Kazakh city of Baikonur only 50 miles away.Fears that the toxic cloud would waft into Baikonur were eased later in the day, however, after heavy rains dispersed the fumes.Photographs posted online had shown the ominous cloud stretching over buildings near the launching pad, and residents of Baikonur, population 70,000, had been instructed to stay indoors and refrain from using air conditioners.The Proton-M rocket rose just above its launching tower at the Baikonur Cosmodrome, wobbled and then tipped over into the desert in a ball of fire.The short flight on Tuesday was the fourth Proton failure in three years, and it was sure to raise safety questions among NASA officials and Western commercial clients of Russia’s space services.In recent years, the National Aeronautics and Space Administration has relied on Russia to provide transportation for American astronauts headed to the International Space Station. But those spaceflights have been powered by a Soyuz rocket that has a far stronger safety record.The Russian space agency did not immediately offer an explanation for the crash.There were no reported injuries at the site of the accident, an area that Russia rents for rocket launchings. But the short flight, instead of a journey to space, made for one of the most prominent rocket disasters in Russia’s space program in recent years.“According to the preliminary estimates from the Russian side, there is no destruction and there are no casualties,” the Kazakh space agency, KazCosmos, said in a statement, according to Reuters.In video of the crash broadcast by Rossiya 24, a Russian state television channel, the satellites appeared to break apart from the nose cone as the rocket tumbled to earth. The station estimated their value at $200 million.In the live broadcast, the announcer noted as the rocket leaned over and flew horizontally, “It seems something is not right.”The announcer goes on to repeat that “something is not right,” and added that “the rocket is now heading toward the ground and breaking apart in the air — and an explosion.”The crash was another setback for the Proton rocket, a workaday booster for the Russian space program that is used for commercial and military payloads.The most pressing concern was the orange cloud, which owed its color to heptyl, a highly toxic type of fuel known as UDMH outside of Russia,  that is used on the larger stages of the rocket. Kazakh authorities were cited by the Interfax news agency as saying they might evacuate towns, though the region is sparsely populated.The Proton is one of the largest rockets used today, weighing 700 tons on the launching pad, according to a reference book published by the Russian space agency. A fully loaded Boeing 747, by comparison, weighs about 400 tons. Most of the rocket’s weight is fuel.Even after successful launchings, herders have found dead cows underneath flight paths, killed by eating grass that came into contact with jettisoned rocket stages contaminated with unburned heptyl.
