DART Mission Successfully Deflects Asteroid Moon Dimorphos.

The Double Asteroid Redirection Test (DART) successfully collided with the moon of an asteroid, Dimorphos, in September 2022, proving the viability of re-routing an asteroid through kinetic impact. Five papers in Nature characterize the impact and its aftermath, advancing our understanding of asteroid-impact geophysics and planetary defense. The results confirm predictions about how asteroids respond to impact and offer useful insights for future space exploration.
