Sometime during this window, the DART spacecraft will slam into the asteroid Dimorphos at roughly 4 miles per second, attempting to slightly change the asteroid’s motion in a way that can be accurately measured using ground-based telescopes. The world’s first full-scale mission to test technology for defending Earth against potential asteroid or comet hazards, DART was launched Nov. 24, 2021.
