The meteorite that streaked at a hypersonic speed of at least 33,000 mph across the morning sky over Chelyabinsk, Russia on Friday, February 15 at 3:20:26 UTC exploded and disintegrated about 18-32 miles above the ground. According to media reports, the shock wave from the explosion estimated as equal to 30 Hiroshima atomic bombs of August 1945, blew out the windows of 900 schools and hospitals, damaged around 100,000 homes, and injured nearly 1,200 people, It induced an undeniable trauma in many residing in and around Chelyabinsk. Fellow blogger, science fiction and fantasy author Bill Housley aptly wrote that it was similar “To Be Shot at and Missed.

Asteroid expert Don Yeomans, head of NASA’s Near-Earth Object Program Office said the object that streaked across the sky over this Russian industrial city was most likely a bolide – an exploding fireball.

The sonic blast shattered windows in and around Chelyabinsk. Scattered amid the broken glass are bits of space rock that sparked on a “meteorite rush.”

Amateur enthusiasts in Russia and scientists alike are scrambling to find bits of the meteorite worth more than their weight in gold. Dmitry Kachkalin, a member of the Russian Society of Amateur Meteorite Lovers said that enthusiasts will pay dearly for them. “The price is hard to say yet … The fewer meteorites recovered, the higher their price,” Kachkalin told Reuters. He estimates that chunks could be worth up to $2,200 per gram — more than 40 times the current cost of gold, the news agency said.

Within hours after the explosion, many residents of Chelyabinsk and its neighborhood  had listed shards of the meteorite on classified ads sites.

International Business Times reported that a person named Andrew advertised 18 pieces of the meteor for 500 rubles (about $16.61) each on avito.ru, – the largest Russian-language free classifieds site. “There are 18 pieces of size as a wristwatch,” Andrew wrote on the site. “You can choose as souvenirs or for stories. BOOK ME IN ADVANCE, to snap up FAST!”

Another Russian felt his rocks were more worthy, asking 300,000 rubles (roughly $10,000) for a piece of the rock. “A piece of the meteor for sale, it’s new,” Sergey wrote, with a photo of himself holding a piece of stone.

On Monday, scientists from Ural Federal University (UrFU) in Ekaterinburg found shards of the meteorite which fell on 15 February near lake Chebarkul near Chelyabinsk, about 1500 kilometers east of Moscow. The expedition team released a photo showing 53 tiny fragments of the meteor each about 0.2-inch-long.

According to Viktor Grokhovsky, a member of the Russian Academy of Sciences‘ Committee on meteorites and the leader of the expedition, told the Interfax news service that the meteorite belonged to the class of regular chondrites. “These stone fragments contain about 10% iron. The meteor is likely to be called ‘Meteorite Chebarkul’,” the scientist said.

He then added: “We have found tiny pieces, about 50-53 in all, and each measure in millimeters. That was all we could find in the snow around the crater. The fragments we found are traces of the outer layer of the meteorite – there is a melted crust and so forth – which mean that the basic mass lies there, in the lake.”

The Meteorite Explosion that Shook Chelyabinsk, Russia on February 15, 2013

Russian Meteor
A meteor seen flying over Russia on Feb. 15 at 3:20: 26 UTC impacted Chelyabinsk.

A meteor entered the Earth’s atmosphere and disintegrated in the skies over Chelyabinsk, Russia, at 7:20:26 PM PST, or 10:20:26 PM EST on February 14 (3:20:26 UTC on February 15).

At a news conference on Friday, NASA scientists said the object was a “tiny asteroid”. The trajectory of this meteor differed appreciably from the trajectory of the asteroid 2012 DA14, which hours later made its flyby of Earth, making both objects completely unrelated.

The Russian Emergency Ministry described it as a shower of meteorite debris. However, some unconfirmed reports suggested that Russian air defenses shot down a meteorite. NASA asteroid expert Don Yeomans, head of the agency’s Near-Earth Object Program Office, said that the object which exploded was most likely an exploding fireball known as a bolide.

According to the preliminary information that appeared in the media unidentified flying objects exploded over several cities in Russia, and the object at Chelyabinsk measured 49 feet (15 meters) across, weighing 7,000 tons and released 30 kilotons of energy when it exploded, and the blast waves blew out window glass of buildings in Chelyabinsk, sending dozens to hospitals, disrupted mobile services, and reportedly injured more than 1,000 people. Many dashboard videos appeared online, showing huge fireballs flying over buildings and exploding with a strong blast. Some walls of the Chelyabinsk Zinc Factory that produced 160,000 metric tons of refined zinc and alloys last year collapsed with extensive damage to the plant.

Now NASA says information provided by a worldwide network of sensors has allowed scientists to revise their estimates for the size of the object before entering Earth’s atmosphere to 55 feet (17 meters), weighing about 10,000 tons. Bill Cooke, head of the Meteoroid Environment Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama said the energy released during the explosion amounted to 500 kilotons equal to that of an exploding modern nuclear bomb.

Fresh data collected from five more infrasound stations located around the world helped to generate these new estimates. The first infra-sound recording of the event took place in Alaska – over 6,500 kilometers away from Chelyabinsk. Calculations performed by Peter Brown at the University of Western Ontario, Canada, using infrasound data show the time taken by the object from entering the atmosphere to its disintegration in the air took 32.5 seconds.

Paul Chodas of NASA’s Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, California said, “We would expect an event of this magnitude to occur once every 100 years on average ”

The present Russia meteor is the largest reported since 1908, when a meteor hit Tunguska, Siberia.

Meteorite or Space Junk Spotted in Night Sky Across UK

On September 21, 2012, thousands of people across Northern Ireland, central Scotland including North of England, the Midlands and East Anglia reported seeing a meteor shoot across the night sky and break into pieces.

Many people described it as a bright fireball with a large tail moving across the night sky.

The Kielder Observatory, located in Kielder Forest, Northumberland, England, twitted: “Huge fire ball from east at 9.55 UTC heading west mag -6 to -7”; “Any other observers? this was big, trajectory went from east, south east and headed to the west, broke up over west coast, many fragments”; “Many many fragments maybe in excess of 100 pieces started green went Yellow, no sound but long obvious termination lasted 20-30 seconds”; “This was an incredible object, different trajectory than March event…lots of structure, slow moving and displaying colour.”

No one knows whether it was a meteor or burning space junk. To many it was just a large fireball. Some suggest that the brilliant sphere of light was not a meteorite but space debris that combusted as it reentered Earth’s atmosphere. Jodrell Bank Observatory tweeted: ‘No real consensus on whether last night’s spectacular fireball was a space rock burning up or space junk (bit of spacecraft).”

The coastguard worried whether it was a crashing aircraft. However, a spokesman for Forth Coastguard said: “From talking to other stations and to the RAF it’s almost certainly meteorite activity.”
