Double Asteroid Redirection Test (DART)
DART made impact with Dimorphos at 14,000 miles per hour- coverage of the collision aired live via NASA TV on September 26, 2022.
On October 12, 2022, NASA confirmed that DART successfully changed the trajectory of the asteroid Dimorphos. "For the first time ever, humanity has changed the orbit of a planetary object," Lori Glaze, director of the Planetary Science Division at NASA.
DART surpassed the initial expectations of astronomers. Had the test shortened Dimorphos' orbit by 10 seconds it would have been a success - the orbit was shortened by more than three times that shortening Dimorphos' orbit by 32 seconds.

Double Asteroid Redirection Test (DART) is a NASA space mission aimed at testing a method of planetary defense against near-Earth objects(NEOs).[3] Launched from Earth in November 2021, the mission was to deliberately crash a space probe into the minor-planet moon Dimorphos of the double asteroid Didymos to assess the future potential of a spacecraft impact to deflect an asteroid on a collision course with Earth through a transference of momentum. The asteroid poses no actual threat to Earth; it was merely selected for the test. -Wikipedia
