NASA To Crash Spacecraft Into An Asteroid To Save Earth

This month, NASA will launch a spacecraft to test a planetary defense method that could save Earth. 

DART (double asteroid redirect test spacecraft) will be used to smash into an asteroid near Earth on September 26. 

This mission is part of an international collaboration to safeguard the planet from future asteroid impacts.

NASA says "the asteroid poses no threat to Earth, but this is the first worldwide test of the kinetic impacts technique, 

Using a satellite to deflect asteroids for planetary defense," NASA added. 

A SpaceX Falcon 9 rocket carrying DART will be launched from Vandenberg Air Force Base, California, in November 2021.

DART will catch up to the asteroid 10 months later by performing three trajectory correction maneuvers in the next three weeks. 

Scientists believe each maneuver will decrease the error margin for the spacecraft's required trajectory to impact Dimorphous.

NASA claims that the navigation team will be able to determine Dimorphos' position 

Within two kilometers after the final maneuver on September 25, 24 hours before impact. 

DART can then guide itself autonomously to the collision with the out-of-this-world space rock.
