More than 1,000 people were injured when a 17 metre, 10,000-tonne space rock burned up over Central Russia, breaking windows and rocking buildings.
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.u00a0The 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 570 kg mark.
Sergey Zamozdra, an associate professor at Chelyabinsk State University, said, "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."
The divers' mission had been hampered by a number of factors. The rock fragment lay at 13-metre depth.
