Soon, NASA's DART mission, or Double Asteroid Redirect Test, will be making impact with the asteroid Dimorphos in the Didymos binary asteroid system. This test will help us understand if a spacecraft could deflect an asteroid on a collision course with Earth. In this live chat, hear from scientists involved in the mission and learn what to watch for on impact day!
