When NASA’s DART spacecraft deliberately crashed into the asteroid moonlet Dimorphos, it did more than change the asteroid’s local orbit — it slightly shifted the path of the entire asteroid pair ...

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 ...

Asteroids with tiny moons may be quietly trading material across space. Images from NASA’s DART mission revealed faint streaks on the moon Dimorphos—evidence of slow “cosmic snowballs” drifting from ...
