Chelyabinsk meteor recovered from Russian lake

Cool find! They spent the entire summer trying to locate it in the lake sediments and pulled it out.

BBC News – Meteorite pulled from Russian lake.

Divers working at a Russian lake have recovered a half-tonne chunk of the space rock that exploded over Chelyabinsk earlier this year.

The object plunged into Lake Chebarkul in central Russia on 15 February, leaving a 6m-wide hole in the ice.

Live footage showed a team pull out a 1.5-metre-long (five-foot-long) rock from the lake after first wrapping it in a special covering and placing it on a metal sheet while it was still underwater.

Dr Caroline Smith, curator of meteorites at London’s Natural History Museum, confirmed that the object was a meteorite from characteristic features known as fusion crust and regmaglypts, which are obvious in images.

Sergey Zamozdra, an associate professor at Chelyabinsk State University, told the Interfax news agency: “The preliminary examination… shows that this is really a fraction of the Chelyabinsk meteorite.

“This chunk is most probably one of the top 10 biggest meteorite fragments ever found.

Originally the meteorite was 17 meters long and weighed 10,000 tons when it entered the atmosphere over central Russia. Its impact injured over 1,000 people, rocked buildings and broke windows.

The 1.5 meter long piece the divers pulled out broke into 3 smaller pieces when it was lifted up to be placed on the scale. And then the scale broke at the 570kg mark. (1,255 lbs)

    Today, I was thinking of the videos from this meteor. I was reading a 1978 UFO roundtable where proponents cited reports of objects travelling 7000 MPH over populated areas (since we can’t do that, ergo, there’s no earthly explanation). But no one brought up sonic booms and the (potential) resultant destruction (which we all saw on YouTube when the meteor passed). You’d think panelists Hynek, Vallee and Harder — all with advanced degrees in the physical sciences — would be troubled by the lack of sound from a supersonic object. But I guess when you already know alien technology can magically violate every physical constraint, you don’t need to worry about such things.

    That’s a really big rock to fall out of the sky! This is interesting in several (undoubtful) directions. While this huge meteorite is surely of incalculable value for its scientific interest, I wonder how much rare earth metals it contains and how much they’re worth. Planetary Resources is just one business looking to find asteroids in near-Earth orbits and mine them for valuable minerals. I like playing with (small, thus relatively safe) neodymium magnets – they have lots of useful applications, but they’re made from rare and expensive metals.

    And which direction did this come from? With all the videos of the event, it’s no doubt possible to calculate where it landed (which they obviously did, unless they had already found the 18-foot swimming hole in the ice), but which direction it came from, and thus where it came from in the Solar System. Was it an asteroid in Solar orbit (most likely), or did it come directly from outside the Solar System? Enquiring (and doubtful) minds want to know!

    It’s the bugs! They took out Beunos Aires like this.

    @Ben Bradley some quick notes. It’s an LL5 chrondrite, “LL stands for Low (total) iron, Low metal”. (wiki). “Multiple videos of the Chelyabinsk superbolide, particularly from dashboard cameras and traffic cameras, helped to establish the meteor’s provenance as an Apollo asteroid.” (also wiki) https://en.wikipedia.org/wiki/Chelyabinsk_meteor
