Watch Live - Double Asteroid Redirection Test Today...

NASA Double Asteroid Redirection Test or DART Mission is set to collide with asteroid Dimorphos on September 26 at 7:14 p.m. EDT (11:14 UTC). Track NASA's DART Mission in Real Time.

NASA will intentionally crash the DART spacecraft into an asteroid to see if that is an effective way to change its course, in case of future Earth-threatening asteroid.

DART is NASA's first mission to demonstrate asteroid deflection by a kinetic impactor.
