NASA spacecraft to smash into asteroid to test planetary defense
β€” “NASA will conduct the world’s first mission to test technology for defending Earth against potential asteroid or comet hazards.

The agency’s Double Asteroid Redirection Test, or DART, will impact the asteroid Dimorphos at 7:14 p.m. ET on Sept. 26.

The asteroid poses no threat to Earth.
DART will provide data to help Earth better prepare for an asteroid that could pose an impact hazard to Earth.

Dimorphos is the smaller moonlet asteroid of the binary asteroid system Didymos, according to the Johns Hopkins University Applied Physics Laboratory, which is developing and leading the mission for NASA.

It has a diameter of 525 feet and orbits the larger asteroid Didymos.
The DART spacecraft will impact Dimorphos almost head-on. The collision will shorten the time it takes the small asteroid moonlet to orbit Didymos by several minutes.”
