Meteorite explodes over Russia, more than 1,000 injured

The Interior Ministry said about 1,200 people had been injured, at least 200 of them children, and most from shards of glass.
People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt the shock wave, according to a Reuters correspondent in the industrial city 1,500 km (950 miles) east of Meteorite explodes over Russia, more than 1,000 injured
The fireball, travelling at a speed of 30 km (19 miles) per second according to Russian space agency Roscosmos, had blazed across the horizon, leaving a long white trail that could be seen as far as 200 km (125 miles) away.Car alarms went off, thousands of windows shattered and mobile phone networks were disrupted. The Interior Ministry said the meteorite explosion, a very rare spectacle, also unleashed a sonic boom.
The meteorite, which weighed about 10 metric tons and may have been made of iron, entered Earth's atmosphere and broke apart 30-50 km (19-31 miles) above ground, according to Russia's Academy of Sciences.The energy released when it entered the Earth's atmosphere was equivalent to a few kilotonnes, the academy said, the power of a small atomic weapon exploding.
No deaths were reported but the Emergencies Ministry said 20,000 rescue and clean-up workers were sent to the region after President Vladimir Putin told Emergencies Minister Vladimir Puchkov to ease the disruption and help the victims.Meteorite explodes over Russia, more than 1,000 injured
WINDOWS BLOWN OUT
The early-morning blast and ensuing shock wave blew out windows on Chelyabinsk's central Lenin Street, buckled some shop fronts, rattled apartment buildings in the city center and blew out windows.A wall and roof were badly damaged at the Chelyabinsk Zinc Plant but a spokeswoman said no environmental threat resulted.One piece of meteorite broke through the ice the Cherbakul Lake near Chelyabinsk, leaving a hole several meters (yards) wide.
The region has long been a hub for the Russian military and defense industry, and it is often the site where artillery shells are decommissioned.
A local Emergencies Ministry official said meteorite storms were extremely rare and Friday's incident may have been connected with an asteroid the size of an Olympic swimming pool that was due to pass Earth.
But an astronomer at Russia's Academy of Sciences, Sergei Barabanov, cast doubt on that report and the European Space Agency said its experts had confirmed there was no link.
The regional governor in Chelyabinsk said the meteorite shower had caused more than $30 million in damage, and the Emergencies Ministry said 300 buildings had been affected.
Despite warnings not to approach any unidentified objects, some enterprising locals were hoping to cash in.
"Selling meteorite that fell on Chelyabinsk!" one prospective seller, Vladimir, said on a popular Russian auction website. He attached a picture of a black piece of stone that on Friday afternoon was priced at 1,488 roubles ($49.46).With a blinding flash and a booming shock wave, a meteor blazed across the western Siberian sky Friday and exploded with the force of 20 atomic bombs, injuring more than 1,000 people as it blasted out windows and spread panic in a city of 1 million.

While NASA estimated the meteor was only about the size of a bus and weighed an estimated 7,000 tons, the fireball it produced was dramatic. Video shot by startled residents of the city of Chelyabinsk showed its streaming contrails as it arced toward the horizon just after sunrise, looking like something from a world-ending science-fiction movie.
The largest recorded meteor strike in more than a century occurred hours before a 150-foot asteroid passed within about 17,000 miles (28,000 kilometers) of Earth. The European Space Agency said its experts had determined there was no connection between the asteroid and the Russian meteor – just cosmic coincidence.
The meteor above western Siberia entered the Earth's atmosphere about 9:20 a.m. local time (10:20 p.m. EST Thursday) at a hypersonic speed of at least 33,000 mph (54,000 kph) and shattered into pieces about 30-50 kilometers (18 to 32 miles) high, the Russian Academy of Sciences said. NASA estimated its speed at about 40,000 mph, said it exploded about 12 to 15 miles high, released 300 to 500 kilotons of energy and left a trail 300 miles long.
"There was panic. People had no idea what was happening," said Sergey Hametov of Chelyabinsk, about 1,500 kilometers (930 miles) east of Moscow in the Ural Mountains.
"We saw a big burst of light, then went outside to see what it was and we heard a really loud, thundering sound," he told The Associated Press by telephone.
The shock wave blew in an estimated 100,000 square meters (more than 1 million square feet) of glass, according to city officials, who said 3,000 buildings in Chelyabinsk were damaged. At a zinc factory, part of the roof collapsed.
