Elon Musk's SpaceX Falcon 9 launch vehicle launched from Vandenberg Space Force Base in California on November 23. The ultimate goal of the launch is an asteroid collision. This is the first ever test of the Earth's protection system from celestial objects.
As a result of the test, NASA wants to know how much such a collision will change the trajectory of the asteroid. The mission was named DART (Double Asteroid Redirection Test - Experiment to change the orbit of a double asteroid)..
