DART: Impact on Asteroid Dimorphos

Is it possible that humanity could stop an asteroid from heading for Earth? I agree. Mass extinctions of life have been caused by large asteroids before. NASA tested a new planetary defense mechanism by crashing a robotic Double Asteroid Redirection Test into a small asteroid. The impact was a success. If hit early enough, the kick from a small craft can be enough to stop the asteroid from hitting the Earth. DART is seen in a time-lapse video first approaching Didymos on the left and then approaching the smaller Dimorphos on the right. Although the video ends abruptly with DART's crash, observations are just beginning.
