The B612 Project

Significantly alter the orbit of an asteroid in a controlled manner by 2015.

Asteroid and comet impacts have both destroyed and shaped life on Earth since it formed.
The Earth orbits the Sun in a vast swarm of near Earth asteroids (NEAs).
The probability of an unacceptable collision in this century is ~2%.
We now have the capability to anticipate an impact and to prevent it.
