After 10 months flying in space, NASA’s Double Asteroid Redirection Test (DART), the world’s first planetary defense technology demonstration, successfully impacted its asteroid target on Monday — the agency’s first attempt to move an asteroid in space.
Mission control at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, announced the successful impact at 7:14 p.m. EDT.
Impact imagery:

Asteroid Didymos (bottom right) and its moonlet, Dimorphos, about 2.5 minutes before the impact of NASA’s DART spacecraft. The image was taken by the onboard DRACO imager from a distance of 570 miles (920 kilometers). This image was the last to contain a complete view of both asteroids. Didymos is roughly 2,500 feet (780 meters) in diameter; Dimorphos is about 525 feet (160 meters) in length. Didymos’ and Dimorphos’ north is toward the top of the image.

The last complete image of asteroid moonlet Dimorphos, taken by the DRACO imager on NASA’s DART mission from ~7 miles (12 kilometers) from the asteroid and 2 seconds before impact. The image shows a patch of the asteroid that is 100 feet (31 meters) across. Dimorphos’ north is toward the top of the image.

This image was the last to contain all of Dimorphos in the field of view. Dimorphos is roughly 525 feet (160 meters) in length. Dimorphos’ north is toward the top of the image.

Back here on Earth, ground observatories monitored the collision.
For example, video by the Asteroid Terrestrial-impact Last Alert System (ATLAS) shows the DART spacecraft impact at Didymos.
ATLAS is an asteroid impact early warning system developed by the University of Hawaii and funded by NASA. It consists of four telescopes (Hawaii ×2, Chile, South Africa), which automatically scan the whole sky several times every night looking for moving objects.
