Killer asteroids have long played a role in science fiction. But when a fireball exploded over Chelyabinsk, Russia in 2013, the world learned that the threat is real.

On average, NASA finds a new potentially hazardous asteroid every day... and there are still many we haven’t found. Many of these space rocks could destroy cities, and some are big enough to wipe out civilization.

On the other hand, they contain the secrets to the origin of our solar system – and could be the key to the survival of the human race.

In the movies, when an asteroid is headed for Earth, there’s always a team of heroes that comes to the rescue and saves the day. But in real life, who can tame these hurtling space rocks? Who can save us from Asteroid Apocalypse – and, just maybe, take us out into the final frontier?

Meet the heroes of MISSION ASTEROID. In the Spring 2010, President Barack Obama boldly declared that NASA’s next mission would be to near-earth asteroids, setting up eventual manned missions to deep space. Mission Asteroid is a documentary about the teams of scientists, researchers and dreamers who will make it happen.
