A NASA spacecraft that will deliberately crash into an asteroid is preparing to launch this week. The goal of the DART mission, or the Double Asteroid Redirection Test, is to hit the smaller of the two asteroids, Dimorphos, with the spacecraft at about 15,000 miles per hour and see how the impact changes the asteroid’s trajectory. Joey Roulette, space reporter at The New York Times, joins Cheddar News to talk more about it.
