Watch Live as NASA Spacecraft Collides With Far-Off Asteroid

NASA’s Double Asteroid Redirection Test (DART), the world’s first mission to test technology for defending Earth against potential asteroid or comet hazards, will impact its target asteroid—which poses no threat to Earth—at 7:14 p.m. EDT on Monday, Sept. 26.
 
DART’s target is the binary near-Earth asteroid Didymos and its moonlet, Dimorphos. Launched in November 2021, the mission will see if intentionally crashing a spacecraft into an asteroid is an effective way to change its course, should an Earth-threatening asteroid be discovered in the future. This test will also show that a spacecraft can autonomously navigate to a target asteroid and intentionally collide with it in a way that can be measured using telescopes on Earth.
 
You can tune in to the live broadcast coverage of DART’s impact with Dimorphos starting Monday, Sept. 26 at 6 p.m. EDT on NASA TV, the NASA website, and on Facebook, Twitter, or YouTube.
