In the world’s first planetary defense test, a
spacecraft from Earth has crashed into an
asteroid to change its motion.
On September 26, 2022, NASA intentionally
crashed a spacecraft into an asteroid
11 million kilometers from Earth.
The target of the mission was Dimorphos,
an asteroid in the binary asteroid system Didymos.
As the two asteroids
orbit the sun, Dimorphos
also orbits Didymos,
circling it every 11 hours
and 55 minutes.
Key facts about the Dart Mission.
DART was a low-cost spacecraft.
DART navigated to crash
itself into Dimorphos at a
speed of approximately
6.1 km per sec.
