France's Le Figaro newspaper said that in 2022, space agencies would launch a simulation test of a life-size experiment that would study how an asteroid could be traced.
The DART, launched by NASA in this experiment, will hit the small moon orbiting the asteroid Demos at more than 21,000 kilometers per hour.
The collision aims to "move" the orbit of this small asteroid, which is 160 meters in diameter, almost the size of Giza pyramid.
This is the first life-size test to change the orbit of an asteroid, says Ian Carnley of the European Space Agency (ESA) and task manager Hera, who will monitor the impact of the collision.
Astronomers with their large antennas and radars should be able - by distance - to measure any change in the orbit of the small moon known as Didimon revolving around the asteroid Demos.
Any change in velocity, no matter how little, about half a millimeter per second, would be enough to remove an asteroid threatening to hit the ground.
The European probe Hira, four years after the collision, should study a detailed study of the asteroid and the collision pit left by Dart.
"We have a great need to know as much as possible about the micro mass, configuration and internal structure of the asteroid," Carnley said.
The possibility of threatening the Earth with a collision with an asteroid exists, and therefore this path must be changed. For this reason, astronomers need to collect this information to verify the accuracy of the simulation and its impact.
The exact shape and size of the crater will include information on the amount of material that is flying in space.
