NASA's DART mission altered the orbits of both Didymos and Dimorphos around the Sun, validating kinetic impact as a viable technique against asteroid collision.

BALTIMORE — In 1998, Bruce Willis saved the world by blowing up an asteroid threat in “Armageddon.” In 2022, NASA did the real thing, crashing a spacecraft into asteroid Dimorphos to prove that we don ...

Europe's Hera spacecraft has completed a major deep-space maneuver, setting it on course to rendezvous late this year with ...

NASA's DART mission didn’t just change the orbit of Dimorphos, the asteroid it hit. It changed the orbit of the larger Didymos around the sun.

New images from NASA's DART asteroid-smashing mission show space rocks exchanging material in a slow process that reshapes their surfaces over millions of years.

NASA’s DART mission changed the Dimorphos' asteroid orbit around the Sun, proving spacecraft impacts could help defend Earth.

The mission without a doubt proves that we could deflect a hazardous asteroid away from Earth — so long as we discover it in ...

NASA’s DART mission proved that a spacecraft can nudge an asteroid system in space, offering a real test of planetary defense ...

Studying the 2022 collision's effects can help scientists protect the Earth from celestial objects that might head toward us ...

In September 2022, NASA’s DART spacecraft rammed into the asteroid moonlet Dimorphos at nearly 15,000 miles per hour (24,000 kilometers per hour). The mission aimed to test whether NASA could one day ...

If an asteroid ever needs to be diverted from a collision course with Earth, a future planetary defense mission may resemble a test NASA pulled off four years ago. In 2022, NASA's DART mission proved ...
