Sandian Mark Boslough Featured on NOVA Episode about Chelyabinsk Meteor

On February 15th, a 7,000 ton asteroid crashed into the Earth’s atmosphere, exploded, and fell to the ground in the Ural Mountains near Chelyabinsk, Russia. According to NASA, the meteor exploded with the power of 30 Hiroshima bombs and was the largest object to burst in the atmosphere since the Tunguska event of 1908—another Siberian [...]
