NASA revealed plans to shoot asteroids close to Earth

NASA announces plans to launch a pilot to change asteroids orbit near Earth.

The US Aeronautics and Space Administration (NASA) said it will conduct its first test in the DART project to change the asteroid's flight direction towards Earth, CNN on July 2, leading to NASA's announcement. good.

DART is a joint project between NASA and the Johns Hopkins Physics Laboratory in Maryland, which aims to eliminate the risk of larger-sized asteroids that could be burnt by the Earth's atmosphere.

The goal of the experiment is the non-threatening Didymos asteroid system, including the smaller Didymos B asteroid that orbits a Didymos A asteroid. NASA will launch a refrigerator-sized spacecraft crashing into Didymos B at 21,436km / h when Didymos approaches the Earth in October 2022.

"This technique changes a fraction of the asteroid's velocity before the collision with Earth takes place, leading to a change in the asteroid's orbit," NASA said in a statement.

NASA will launch a refrigerator-sized spacecraft crashing into Didymos B at 21,436km / h.

Scientists will study the impact of the experiment on Didymos B's trajectory to consider the effectiveness of this method in protecting the Earth.

Scientists believe this is an effective method of protecting the Earth . "DART is an important step to show that we can protect the Earth from a collision with asteroids in the future," said Andy Cheng, one of the leading scientists of the Johns Hopkins lab. The plan for the experiment was announced by NASA on June 30, International Asteroid Day.
