In 1908, a space rock 120 feet (37 meters) across hurtled through the Earth's atmosphere and exploded over Siberia with the energy of 185 Hiroshima bombs, demolishing 800 square miles (2,072 square km) of forest in a matter of seconds. That devastating impact, known as the Tunguska event, is just one example of what could happen if one of the massive objects hurtling through our solar system were to take a collision course with Earth. Luckily, NASA's doing something about it. It plans to try out an asteroid-deflection technique involving a pair of space rocks, a refrigerator-sized spacecraft, and one badass crash landing.
