NASA spacecraft to crash into an asteroid to help save Earth

NASA is going to use a spacecraft to test a planetary defense method that could one day save Earth.

The Double Asteroid Redirect Test spacecraft (DART) will be used to crash into an asteroid not far from Earth on Sept 26.

The mission is an international collaboration to protect earth from future asteroid impacts.

SpaceX Falcon 9 rocket launched with DART from the Vandenberg Air Force Base in California in November 2021.

After 10 months DART will crash into the asteroid by executing three trajectory correction maneuvers over the next three weeks.

After the final maneuver on Sept 25 (24 hours before impact) navigation team will know the position of Dimorphos within 2 kilometers.
