1.5 Meter Long Meteorite Fragment Recovered From Russian Lake
MancunianMaskMan writes "The BBC writes about the meteorite that fell from the sky 8 months ago: '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.'"
This is one of the ten largest meteorite fragments ever recovered. Unfortunately, it broke into three pieces after being lifted from the lake, and managed to destroy the scale used to weigh it when it hit 570kg.
After reading the summary and scanning the article (in true Slashdot fasion!) I went to look at the comments... and they are all complete drivel. Tons of stupid jokes and no actual discussion of the event. What the hell has happened here??
Anyway - back on topic: Does anyone else feel like that rock is WAY too big to have only left a 6m hole in the ice? That rock impacting the ice/water would have been an enormous event... it would have vaporized a ton of water and blown the ice away for at least several hundred feet.
Something doesn't add up here.
