NASA:

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.

As a part of NASA’s overall planetary defense strategy, DART’s impact with the asteroid Dimorphos demonstrates a viable mitigation technique for protecting the planet from an Earth-bound asteroid or comet, if one were discovered.

I love that this is a thing we do now, just fire ships at stuff in space. NASA rules.
