Over the weekend, scientists collected 53 tiny pieces of dark porous material that were recovered by local residents near Chebarkul Lake, 60 miles west of Chelyabinsk, the regional center, officials said. The biggest of the finds was 7 millimeters long.
Not everyone who found the objects turned them in, apparently: Some enterprising locals were offering what they claimed to be fresh meteorite pieces for sale online for as much as $10,000 apiece. Some attributed far-reaching (if bogus) powers to the space rocks.
"Improves male potency, reduces weight," one ad claimed. "Trade in for a car or real estate a possibility."
The pieces collected by scientists were described as bits of chondrite, a type of stony meteorite, which contained at least 10 percent metallic iron and nickel alloy as well as chrysolite and sulfite, according to Viktor Grokhovsky, a member of the Russian Academy of Sciences meteorite committee.
"We are certainly dealing with the debris of the object that traveled here from outer space," Grokhovsky, a professor at Yekaterinburg-based Urals Federal University, said in a phone interview. "We sent our team to the lake as soon as we heard of the meteor falling, as it is extremely important to find and study fresh debris."
Russian scientists also said they had submitted a preliminary proposal to the government for an early-warning system for future space threats. Lidiya Rykhlova, a senior researcher with the Institute of Astronomy, told the RIA-Novosti news agency that the plan had been put together with Roskosmos, the federal space agency, and involved the construction of new and larger telescopes that could detect relatively small meteorites. Scientists put the cost at almost $2 billion over the next decade, Rykhlova said.
The meteorite, estimated at 55 feet wide and 10,000 tons, exploded in the atmosphere Friday with the power of several nuclear bombs. Shock waves shattered more than 1 million square feet of window glass, local officials said. Hundreds suffered minor injuries. A woman who suffered a broken spine was flown to Moscow for surgery and treatment, the Emergency Situations Ministry said.
After the explosion, residents discovered a 24-foot-long hole in the thick ice on the lake. Police cordoned off the lake and a team of divers attempted, without success, to retrieve any part of the meteor they could find.
"The fact that the divers' initial inspection produced nothing absolutely doesn't mean a big chunk of the meteorite is not there, and I am absolutely confident it should be there now that we have established its solid composition," Grokhovsky said. "We certainly need to take another go at the bottom of the lake as soon as possible and do it as professionally as we can."
He said scientists were planning to name the meteorite Chebarkul, after the lake.
