Although DART was launched on November 24, 2021 on a SpaceX Falcon 9 from Vandenberg Space Force Base, California, the mission will end in the fall of 2022. On this date the asteroid in question will be 11 kilometers from Earth.
Just when the asteroid is at that distance, the spaceship will achieve the deviation of the impact by crashing into the asteroid, approximately with a speed for 6,6 km / s, with the help of an camera aboard, DRACO, and sophisticated software. The collision will change the speed of the asteroid in its orbit.
For me, it is a great fact because thanks to this mission the deviation of asteroids by impact kinetic, they can test the method. This fact can open doors to new methods.
