The first flight mission for planetary defense, NASA's Double Asteroid Redirection Test (DART) seeks to validate a method to protect Earth from the threat of an asteroid impact. By smashing a spacecraft into the smaller member of the binary asteroid system Didymos,

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.

There were concerns that Asteroid 2024 YR4 could hit the moon or Earth.

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 the nick of time.

In one of the biggest surprises of NASA's OSIRIS-REx mission, its target asteroid, Bennu, turned out to be a jagged, rugged world covered in large boulders, with few of the smooth patches that earlier observations from Earth-based instruments had indicated.

A loud boom heard across Cleveland on Tuesday morning could have been caused by a meteorite, according to the National Weather Service. The NWS office in Cleveland responded with a tweet saying, "The latest GLM imagery (1301Z) does suggest that the boom was a result of a meteor.

TransAstra has developed a plan to bag an asteroid and move it to a stable near-Earth orbit for processing. Reading time 2 minutes There are roughly 250 small, near-Earth asteroids teeming with precious resources that are ripe for extraction.

The spacecraft slowed down the system's 76,000 mph orbital speed... by two inches per hour. We're going to have to punch a lot harder if we want to save Earth.

NASA says there's now zero chance that asteroid 2024 YR4 will crash into the moon in 2032. The space agency had been predicting a 4.3% chance of a direct hit.

Asteroid 2010 RA91 will pass relatively close to Earth, but if it poses no threat, why are scientists still watching it so closely and what could change?
