The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects (NEOs). [4] [5] It was designed to assess how much a spacecraft impact deflects an asteroid through its transfer of momentum when hitting the asteroid head-on. [6]
The DART impact on the center of Dimorphos decreased the orbital period, previously 11.92 hours, by 33±1 minutes. This large change indicates the recoil from material excavated from the asteroid and ejected into space by the impact (known as ejecta) contributed significant momentum change to the asteroid, beyond that of the DART spacecraft itself.
In 2022, NASA launched the Double Asteroid Redirection Test (DART) spacecraft, whose sole goal was to fly 7 million miles to the 525-foot asteroid Dimorphos, and crash into it at 14,000 miles per ...

The pioneering NASA spacecraft has made make science fiction a reality - or at least that’s the theory.
DART, or Demonstration for Autonomous Rendezvous Technology, was a NASA spacecraft with the goal to develop and demonstrate an automated navigation and rendezvous capability. At the time of the DART mission, only the Roscosmos and JAXA had autonomous spacecraft navigation.
NASA's DART mission was a success. Images taken by satellite show plumes from the asteroid impact, but it could take weeks to monitor for changes in the asteroid’s trajectory.
