The test will take place as part of a test of the Earth's protection system against the threat of collision with asteroids.
For this, the DART satellite was launched into space last year, which will hit the asteroid at high speed and possibly change its trajectory.
They will shoot down the 165-meter asteroid Dimorph, which orbits the asteroid Didim (they do not threaten the Earth).
After the collision, scientists want to know how the orbit of its rotation will change, and to understand what force must be applied to change the direction of the space body's flight in case it threatens the Earth.
The collision is scheduled for September 27, NASA promises that the entire process will be broadcast live.
