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 ...

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

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

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

Dimorphos and Didymos do not pose an actual threat to Earth. The spacecraft collided on Sept. 26, 2022, at about 14,000 miles per hour into Dimorphos, an asteroid that was about 560 feet wide, ...

Prior to the mission, Dimorphos took 11 hours and 55 minutes to orbit its parent. After the collision the orbit had been reduced to 11 hours and 23 minutes, a full 32 minutes fewer than before.
