When a vending-machine-sized spacecraft hit Dimorphos in 2022, planetary defense experts anticipated an easy test of kinetic ...

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 ...

When NASA's DART mission crashed into the asteroid Dimorphos, the first stage of the impact saw the spacecraft's solar panels ...

NASA's DART mission successfully altered Dimorphos' orbit, but the impact unleashed over 100 boulders, significantly boosting ...

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

In the almost three years since NASA proved that it could successfully deflect an asteroid, we’ve learned a lot about these ...

When NASA’s DART spacecraft collided with a small asteroid moon in late 2022, the impact made history. It was the first ...

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

When NASA steered its Dart probe into an asteroid, it was supposed to determine how much it could be deflected. The ...

NASA's DART spacecraft unintentionally triggered a massive boulder ejection upon impacting asteroid moon Dimorphos, ...

These boulders, which range in size from 0.2 to 3.6 meters (0.7 to 11.8 feet) in radius, shot away from Dimorphos at speeds up to 52 meters per second (116 miles per hour) after impact.

Primarily, an analysis of the craters and surface strength on Didymos indicated it formed about 12.5 million years ago, while its smaller companion, Dimorphos, formed about 300,000 years ago.
