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.
As per a report by Space.com, Paul Chodas, manager of the Center for Near-Earth Object Studies (CNEOS), NASA, was working on a NASA TV segment for the flyby of a near-Earth asteroid on that day, which was predicted to make a safe passage across the Earth. During his preparation, someone sent him a YouTube video of the Chelyabinsk meteorite explosion and asked whether NASA got the prediction wrong. Chodas revealed that they knew exactly where that asteroid was and this event was entirely separate from it.
It turns out that as the meteor approached from the direction of the Sun, it blinded the astronomers and no one saw it coming before it was too late.
The event underlined the desperate need for an organized system that can track and monitor asteroids and also build asteroid defense systems that can take on any hostile space rocks aiming for the Earth. In the following years, NASA doubled down on these initiatives and established a stronghold on near-Earth asteroids. CNEOS today tracks more than
