Looks like a small meteoroid decided to spoil 2012 DA14's big day by exploding over Russia...

Yep, "fragments found" and now we're going to see the squirrels come out of the woodwork with eBay sales.
"Meteorite rush" begins as Russian scientists find fragments http://news.yahoo.com/meteorite-rush-begin...dF9BRkM-;_ylv=3 But it is good that (actual) fragments are turning up. It gives an idea of the composition, and therefore the type of asteroid and the structure and a better understanding of the dynamics of the breakup. From the Russian scientists involved, "These are classified as ordinary chondrites, or stony meteorites, with an iron content of about 10 percent..." I liked this comment: QUOTE "I will keep it. Why sell it? I didn't have a rich lifestyle before, so why start now?" a woman in a pink woolen hat and winter jacket, clutching a small black pebble, told state television Rossiya-24. This is not surprising. When the object disintegrated it didn't completely flash into plasma. No doubt many small fragments were decelerated quickly and fell along the flight path in a ballistic trajectory. I look at the object as being converted into a flying gravel pile-- even if only 1/10 of 1% survived, that is a lot of meteorites! --Bill -------------------- |
