New study finds that DART changed both orbit and shape of Dimorphos asteroid

On Sept. 26, 2022, NASA’s Double Asteroid Redirection Test (DART) spacecraft slammed into the side of the 170-meter-wide asteroid Dimorphos to test future asteroid deflection tactics in the event an asteroid was threatening Earth. Following impact, DART teams confirmed that the spacecraft’s collision with the asteroid had successfully deflected the asteroid by a small amount — proving the design of the deflector and allowing scientists and engineers to better understand the ways we can protect Earth from asteroids.
