Wahhey, I was just watching "wonders of life" the other day and Cox said it, 46,000 Tonnes every year.

70% at sea.

A while back they had robots scouring the tops of glaciers in Antarctica. The wind evaporated the snow so you could see what was inside them. And the only way rocks could be on top of several hundred meters of ice is if they fell from the sky.

Out of the 56,000 meteorites in total, 38,000 have been found in Antarctica

There's a program on Channel 4 this Sunday night at 8:00 pm about it, asking what it was and where it came from, might be good to watch. It's called "Meteor Strike: Fireball from Space" ... here is the link :

What's the likelihood of Earth being struck by another meteorite like the one in Russia? And what can be done to protect our planet?

Don't forget it's also on Channel 4 +1 (SKY 135)

boring enough ....

Another one starting now on BBC2, 'The truth about Meteors'.

We got sucker-punched from the direction of the Sun where we can't see it coming from.
Sneaky rock.

Gotta agree. The subject matter is interesting and fascinating enough without them giving the impression that there's a malevolent Asteroid Cloud out there just firing 'em our way to see if one will flatten a city... "like a giant game of interplanetary billiards".

repeated again right now on C4, and in an hour on +1.
Whatever about the content the actual videos are fascinating.

I saw the one over Ireland a few months ago and that too came from unusual direction.

The silence regarding the meteorite fragments is weird, makes you almost believe the conspiracies...

there have now been many hundreds of stones recovered.The biggest one so far is 1.8 kilos though I expect that to be exceeded when the snow melts and searching continues.I'll post some pictures that are in the public domain of a friends recovery efforts for this meteorite which is now officially called Chelyabinsk http://www.lpi.usra.edu/meteor/metbull.php?code=57165

MeteoritesEire

the 1.8 kilo current main mass( this refers to the largest known meteorite currently recognised)



395 grams of gorgeous fusion crusted individuals



hundreds of stones bought by Mike Farmer, an American meteorite hunter who is at this very minute travelling back from the impact zone.All pictures are his property and he retains rights although they are in the public domain and he would be only too happy to share.

1.8kg would be a pretty miserable top specimen from such a dramatic impact, its quite strange why the divers recovered nothing from the bottom of that lake... I also read the Duma was debating a law to prevent foreigners grabbing hold of Russian space rocks, I would say Mike Farmer is fairly hotfooting it for the border as we speak

MeteoritesEire

it's funny actually because Tunguska was by all calculations a much bigger event but nothing has ever been recovered other than specks in fallen trees (edit to add that the explosion pulverizes and disintegrates the object as happened in both Tunguska and Chelyabinsk.The latter was estimated at 7,000 tons and the explosion estimated at 30 Hiroshimas)).The lake bottom will likely yield something at some stage I would think,it's probably quite deep under the lake mud.As for laws--well thats a whole can of worms I'm not going to get into at the moment but Mike was very welcome and left a lot of Russians very wealthy and happy ;-)

oh one more shot of the interior of one of the stones--they will all have this brecciation to some degree

Rhys Essien

Id say he will make some profit when he sells them on.I would be tempted to buy one.He has plenty others for sale on his site.

MeteoritesEire

He deserves all profit he makes, I certainly tip my hat to him for having the goolies to go get these rocks while the majority of us sit on our comfy sofas and watch.I will almost certainly get some myself although I'll likely wait til the price goes down once more are recovered after the snow melts.Current pricing seems to indicate $40-$50 a gram

he'll love you for the link LOL

Very true. As a Yank venturing into the Russian badlands, all the while carrying bundles of cash, he must have b**ls of steel

Russian Scientists Find Crater in Meteorite-Hit Lake
RIA Novosti
March 21, 2013

MOSCOW, March 21 (RIA Novosti) - A radar probe of the bottom of
Chebarkul Lake in Russia's Urals has revealed a crater possibly created
by a fragment of a meteorite that exploded over the city of Chelyabinsk
last month, a Russian scientist told RIA Novosti on Thursday.

The meteorite broke into approximately seven large fragments and one of
them is believed to have fallen into Chebarkul, forming a hole in the
ice about eight meters in diameter.

Analysis of minute rock fragments collected near the hole has confirmed
that they are from a meteor. Tests revealed they were chondrite, which
is the most abundant type of meteorite, and contained some 10 percent of
iron.

Scientists from Russia's Institute of Earth Magnetism, Ionosphere and
Radio Wave Propagation (IZMIRAN) carried out a study of the lake's
bottom using wide-band earth-sensing radars.

"A 3D image of the bottom shows a 3-meter crater that could have very
probably been created by impact with a large meteorite fragment," said
IZMIRAN researcher Alexey Popov.

Popov said the crater is not located directly beneath the hole in the
ice, but is some 10 meters to one side of it.

Emergencies Ministry divers searching the site in February failed to
find any traces of the meteorite as the bottom of the lake was covered
in a thick layer of silt.

The meteorite that slammed into the Urals region of central Russia on
February 15 landed with a massive boom that blew out windows and damaged
thousands of buildings around the city of Chelyabinsk, injuring 1,200
people in the area. Health officials say 52 people were hospitalized.

NASA estimates the meteorite was roughly 15 meters (50 feet) in diameter
when it struck Earth's atmosphere, travelling faster than the speed of
sound, and exploded in a fireball brighter than the sun.

MeteoritesEire

lots of detailed info about this historic event now compiled by Dr Svend Buhl on his excellent website
http://www.meteorite-recon.com/en/Meteorite_Chelyabinsk_6.html

The main mass in the lake is estimated to be between 200 and 800 kilos

Around the World in Four Days: NASA Tracks Chelyabinsk Meteor Plume

A meteor weighing 10,000 metric tons exploded 14 miles above Chelyabinsk, Russia, on Feb. 15, 2013. Unlike similar past events, this time scientists had the sensitive instruments on the Suomi NPP satellite to deliver unprecedented data and help them track and study the meteor plume for months.

MeteoritesEire

they have started pulling up fragments from the lake

http://vk.com/video_ext.php?oid=11467297&id=166378528&hash=c2821f4a5482c8fb&hd=3

this meteorite now has its own church They oppose bringing up the fragments.


''The founder of the cult of the meteorite opposes the operation to bring the chunk out of the lake, claiming that only “psychic priests” of his church are qualified to handle the celestial body, which they want to be placed in a temple to be built in Chelyabinsk for the purpose.''

And then broke it into three.

http://www.bbc.co.uk/news/science-environment-24550941

The fragment was then pulled ashore and placed on top of a scale for weighing, an operation that quickly went wrong.

The rock broke up into at least three large pieces as it was lifted from the ground with the help of levers and ropes.

Then the scale itself broke, the moment it hit the 570kg (1,255lb) mark.

MeteoritesEire

apparently it broke underwater during the lifting operation.Someone posted a vid on bakebook, I'll hunt it down

well, there is an extensive crack showing between 5:10 and 5:40 although it doesn't actually split underwater
