It ultimately was successful, with NASA correctly predicting that it is possible to redirect celestial objects. The asteroid known as Dimorphos was approximately the size of the Great Pyramid of Giza, ...

In 2022, NASA rammed a spacecraft into an asteroid to see if it could alter its orbital period around its parent asteroid. The mission, dubbed the Double Asteroid Redirection Test (DART), aimed to ...

Planetary defense scientists say NASA’s DART asteroid redirection mission sent space rocks hurtling on unexpected ...

How does a planetary defense mission intended to push an asteroid off course manage to release a torrent of boulders with the same momentum as the spacecraft? NASA’s groundbreaking experiment, the ...

There are currently no known asteroids on an impact course with the planet. Still, scientists are keeping a watchful eye on ...

When NASA’s DART (Double Asteroid Redirection Test) spacecraft collided with the asteroid moon Dimorphos in September 2022, ...

When NASA's DART spacecraft slammed into the asteroid moon Dimorphos in September 2022, it didn't just change the asteroid's ...

NASA has announced that an asteroid about 200 feet in diameter is now slightly more likely to crash into the moon.

NASA has significantly lowered the risk of asteroid 2024 YR4 hitting the Earth in 2032 through recent calculations. The moon however, may not be in the clear.

“NASA analysis drops asteroid 2024 YR4's impact probability to 0.004%, meaning it is expected to safely pass by Earth in 2032,” NASA’s Planetary Defense Coordination Office posted on X Monday.

NASA’s OSIRIS-REx mission has an historic opportunity to closely observe the asteroid Apophis and improve our ability to defend against future asteroid threats, but government budget cuts are… ...

My favorite thing about Armageddon is that NASA—thanks to a tipoff from a citizen astronomer—discovers an asteroid the size of Texas just 18 days before impact.
