NASA’s Double Asteroid Redirection Test (DART) mission aimed to redirect a potentially hazardous asteroid.
The collision successfully altered Dimorphos’ trajectory.
The collision ejected millions of tiny fragments into space.
Some of these fragments may be on a collision course with Earth and Mars.
While the fragments pose no significant threat to life on Earth, they could trigger meteor showers.
The fragments could start hitting Earth within a decade.
If the fragments reach Earth, they could create a new meteor shower.
The DART mission has revealed a new potential consequence of human intervention in space.
