DART is the first-ever space mission to demonstrate asteroid deflection by kinetic impactor.
The DART impactor is a simple spacecraft, equipped with a camera and the ability to autonomously guide itself to impact the asteroid.
"Planetary defense" encompasses activities undertaken to understand the hazards posed to Earth by potential impacts of asteroids and comets and to develop approaches to prevent or minimize the effects of those impacts.
