Russia sends clean-up team to meteorite-hit Urals

Source: BBC News

A big rescue and clean-up operation involving up to 20,000 workers is going on in the Ural mountains following Friday's meteor strike, Russia's emergency ministry says.

President Vladimir Putin ordered the operation to help some 1,200 people who were injured, including 200 children, mostly by shattered glass.

The shockwave blew out windows and rocked buildings around Chelyabinsk.

A fireball streaked through the clear morning sky, followed by loud bangs.

1. This will be an

interesting story to follow over the long haul and see just what was in that meteorite.

3. Ancient humans would heat meteorites and pound them into spear tips

I like to imagine that there is some meteor metal in the spoon I am eating with.

7. When I visited the British Museum, there was this round "Meteorite Room" and...

...they had a couple of daggers that had been made out of meteorites. There were things in that museum that I saw that I would have never imagined A) Would not have been lost to history or B) I never imagined the hands of men could create. Like, oh, crap, off the top of my head, like an exquisitely gilded necklace of hummingbird heads from the 1860's. Pictures of the thing don't do it justice.

Some of the meteorite daggers they had were named. Like, Excalibur style, each with some wild backstory. Crazy shit.

14. Would that have been the "Natural History Museum"?

That is what my google searches have come up with so far: http://www.nhm.ac.uk/nature-online/space/meteorites-dust/

You would love the Cleveland Museum of Art for a similar collection Medieval Art and the Faberge collection come to mind: http://www.clevelandart.org/art/collections

20. For all the ribbing Cleveland takes...

they have a fantastic art and theater district. And don't get me started on the downtown library.
On edit: I forgot about the world class orchestra.

9. They didn't acutally use heat to pound them into spear tips

They worked the iron cold. They also discovered the limits on how much to could work it until it would break or shatter. Their breakthrough, their technological discovery was when they discovered if they heated the iron piece they had been working, it released tensions, normalizing it, and found they could continue working the iron cold.

At least that's what the Inuit's discovered, I don't know about ancient humans

4. a question comes to mind - any radiation associated with meteorites?

6. Not too much.


At least not from isotopes. The heavier, radioactive elements are rare and would have had several billion years to decay. Exposure to space radiation might have created a few, but nothing created that way could be heavier than iron.

Frankly, I'm more afraid of an attack by the blob now.

12. Any this size would just be chunks of rock and/or iron

Most likely iron if it was that small and made it to the surface.

I imagine their staff are racking up some overtime right about now...

8. I didn't hear anything about this meteorite, just...

the one that passed that afternoon. Did NASA know about this; why weren't we warned?

11. The sky is very very very big and the meteor was quite small.

Most tabs being kept on objects are either space junk in Earth orbit - which is quite nearby and completely preditable in their movements - or much larger objects than the one that went off over Russia, which was also moving far faster than orbital debris.

A handful of pieces like this come down somewhere in the world every year, usually over the ocean. They're too small to see coming without a lot of time and equipment that isn't budgeted for right now; we're barely able to keep tabs on bigger objects.

16. The latest

I just read was that the energy yield of the explosion caused by this bolide was on the order of 500 kilotons.

That would wipe out a city if it detonated lower in the atmosphere, say around half a mile up.

Chelyabinsk dodged a bullet.

21. Northern Europe dodged a bullet too

 

If it had hit several hours later, it would have been at a much steeper angle and more likely to penetrate into the lower atmosphere, or hit the ground. Poland, Germany, Denmark, Sweden, Norway, Finland, etc. would have been at risk.

17. Why Weren't We Warned?

Because it came out of the day sky and couldn't be seen meaning it had looped around the sun and was returning to deep space. The rock we were warned about was coming from deep space and heading toward the sun because it was in the night sky. This piece of rock was in the passing lane going roughly 100,000 mph and passing Earth going a measly 66,000 mph, but it got too close and crashed.
