How NASA Plans to Save Earth from Asteroids The Space Show
VICE News
The Double Asteroid Redirection Test is NASA's first test of a "kinetic impactor" that could one day be used to save Earth from an incoming asteroid. Andy Rivkin, an asteroid expert with The Johns Hopkins University Applied Physics Laboratory, explains how to smash into giant space rocks and possibly save human civilization.
P.S. Apologies if that video has been posted before (didn't see it).
