NASA will try to "shoot down" the asteroid live.

The test will take place as part of a test of a system to protect the Earth from the threat of asteroid impacts. For these purposes, the DART satellite was launched into space last year. The essence of the test is that the satellite will crash into the asteroid at high speed and possibly change its trajectory. The goal of the mission was the asteroid Didim, or rather the smaller Dimorph asteroid revolving around it. After the collision, scientists want to know how the orbit of rotation of this 165-meter “satellite” around a larger asteroid will change, and at the same time understand what force must be applied to change the direction of the flight of a cosmic body if it threatens the Earth.
