In Russland haben sie ein Fragment von dem Meteor gefunden, der im Frühjahr 2013 über der Stadt Chelyabinsk verglühte. Das Ding ist 1,5 Meter breit und wiegt stolze 570kg.
The object plunged into Lake Chebarkul in central Russia on 15 February, leaving a 6m-wide hole in the ice. Scientists say that it is the largest fragment of the meteorite yet found. 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.
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.
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. She told BBC News: “Fusion crust forms as the meteoroid is travelling through the atmosphere as a fireball.
