Chelyabinsk Meteorite Hit The Earth Like A Warning Shot Fired From Space

Just after sunrise on 15 February 2013, as commuters made their way along snow-covered roads to Chelyabinsk in south-west Russia, the clear blue sky was torn by a hurtling lump of space rock.

The meteorite appeared without warning, out of the sun, on a shallow trajectory. It thumped into the atmosphere at 12 miles per second and became a fireball. For a moment, the rock burned 30 times brighter than the sun.

Viktor Grokhovsky, a researcher at Ural Federal University, 200km to the north of Chelyabinsk, missed the beautiful, terrifying spectacle that morning, but within minutes was watching video of the event. He spent the rest of the day assembling a search party. The first of several set out at first light the next morning to interview eyewitnesses and recover pieces of the fallen rock.


“It was rather easy to find fragments in the first days after the meteorite fell, because the chunks left holes in the snow,” Grokhovsky told the Guardian. But as more snow fell over the next two weeks, the holes became covered over. The search was called off until the snow began to melt in the spring.

Nothing the size of the Chelyabinsk meteorite had fallen to Earth in 100 years, and never over an urban centre where its dramatic arrival would be captured by CCTV and dashboard video cameras installed by Russians wary of insurance scams and crooked police.

“This was the first time in modern, medieval or ancient history when a meteorite fell in an area with a high density population. This type of meteorite is rare and a lot of material fell. All these factors give excellent opportunities for extraterrestrial substance research. The hazard from asteroids and comets, people’s behaviour in emergencies, and the shortage of astronomical education are all on the agenda,” said Grokhovsky.

After much of it had burned away was 650 kb or 1433 pounds...

It was very fragile and broke into 3 pieces. They managed to get more extraterrestrial material from that one asteroid than several of the US space missions....

Eerie that it landed in the morning when everyone was out and about, pictures taken on their car cameras, and no one killed, maybe 1200 injured mostly by broken glass...

I can see why they thought it was a warning . . . but to who and for what and from who? Article doesn't say...

Thanks for posting . . .

It's fascinating that there wasn't immediate panic in the streets.

If I saw that thing coming in, I'd be thinking one thing:

It's a horrible bandwidth eater. Bad code which locks up the browser in order to put all sorts of foolish active video content in your face, hoping that one does not really want to read the linked to content.
