NASA is about to crash a spacecraft into an asteroid. Here's why the mission could one day save humanity.

In a first-of-its-kind maneuver, a spacecraft is set to smash into an asteroid to test whether deflecting a space rock could one day protect Earth from a potentially catastrophic impact.
The Double Asteroid Redirection Test (DART) will help determine if intentionally crashing a spacecraft into an asteroid is an effective way to change its course.
