Shocking meteor EXPLOSION forced NASA to trigger its asteroid defense-the Chelyabinsk event
On February 15, 2013, 10 years ago, a 59-foot wide meteorite exploded over the city of Chelyabinsk, Russia. The explosion caused the meteorite to break down into small rocks which rained on the city. While it did not cause any loss of life although many were injured due to the intense heat from the blast, many injured from glass shards from broken windows that were struck by the rocks and others reported eye damage from the excessively bright spark. This event became a pivotal moment for humans to recognize the terrifying threat that floated above them. Many astronomers believe that this event led to a period of intense research and development of technology in the field of astronomy that was dedicated to asteroid defense mechanisms.
