Ten months ago, NASA launched a rocket into space to rendezvous with Dimorphos, a tiny asteroid 11 million kilometers away. It was part of the Double Asteroid Redirection Test (DART) mission, a planetary defense test to see if we could deflect any incoming asteroids that might collide with Earth. On September 26, 2022, at 7:14 pm EDT, the rocket went kersplat at 6.5 kilometers per second right on target. Was it enough to alter the course of Dimorphos’s orbit? We’ll find out in another two months. But until then just how cool is it we managed to hit an asteroid with a rocket?
