A search team arrives at a frozen lake on Saturday to look for fragments of the meteorite that hit the area the previous day. Divers searched the frozen Lake Chebarkul in the Chelyabinsk region of Russia but failed to find any large fragments. NASA says the meteor exploded miles above the earth's surface and released 500 kilotons of energy--about 30 times the size of the nuclear bomb dropped on Hiroshima in World War II. They also estimated that the meteor was 17 metres across before entering Earth's atmosphere and weighed about 10,000 tons. The Russian space agency, Roscosmos, say the object traveled at a speed of 30km per second, leaving a long white trail visible as far as 200km away. More than 1,000 people were injured by the shock wave and buildings suffered structural damage. The regional governor said the impact and damage would cost 33 million U.S. dollars.
