It sounds like the plot of an ‘end of the world’ sci-fi movie. But this is not fiction. Today, NASA will be attempting to power a rocket into an asteroid to alter its course. And you can watch it live, via possibly the world’s ultimate field-cam, the asteroid-cam.
NASA’s Double Asteroid Redirect Test (DART) is headed straight for the asteroid called Dimorphos. The asteroid will be struck at around 14,000 mph and is billed as a test drive to see if the technique could work even a tiny bit in the case of an asteroid coming dangerously close to hitting the earth.
