To save Earth, NASA will crash into an asteroid

This month, NASA will test a planetary defence system. On September 26, DART will be used to destroy an asteroid. Collaboration between nations to protect Earth from asteroids.

Although the asteroid poses no threat to Earth, this is the first attempt to use the kinetic impact method, according to NASA.

DART was launched in 2021 from California's Vandenberg Air Force Base by a SpaceX Falcon 9 rocket.

Now, 10 months later, DART will catch up by conducting three trajectory correction procedures over the ensuing three weeks. Each manoeuvre lowers the spacecraft's chance of hitting Dimorphos.

Following the final manoeuvre on September 25, according to NASA, the navigation team will be able to pinpoint Dimorphos' location to within two kilometres 24 hours before impact. 

The space rock will then be reached independently by DART.

The Didymos system appeared weak from a distance of 20 million miles. Astronomers discovered Dimorphos after merging images.
