Document Summary
Video: chelyabinsk meteor: what did the nuclear weapons monitoring system reveal about the explosion of the meteor, describe the composition of a stony iron meteorite. The chelyabinsk meteor fragments were found to be 90% rock and 10% metal. Over 15 million pounds, about the weight of the eifel tower. Hope to calculate the precise path to find out where it came from. Will tell them if its representative of original object. Hits atmosphere going to fast that it exceeds the strength of asteroid so breaks apart early in its entrance. Cracks and fractures in it while it was in space, once it hits atmosphere it explodes all at once. If the blast wave were focused more downward (sharper angle) would be far worse. So close to the sun that no one saw it coming because earth hit the asteroid and not the other way around. Infrared telescope in space and would take up space in an orbit around the sun.
