Dart (rocketry)

DART (Double Asteroid Redirection Test) is a NASA mission aimed at testing a method of planetary defense against potential asteroid threats. Launched on November 24, 2021, the DART spacecraft's primary objective was to demonstrate the kinetic impactor technique, where a spacecraft deliberately collides with an asteroid to change its trajectory. The mission targeted a binary asteroid system called Didymos, specifically its moonlet, Dimorphos.
