Though Dimorphos posed no threat to Earth, DART was made to collide with it to change the asteroid's speed and path, as a test of NASA's ability to achieve a kinetic impact on an asteroid and observe its response. The team will use telescopes on Earth to study how much the spacecraft's impact changed the asteroid's motion in space.
