Story summary

NASA's DART mission made history in September 2022 by changing the orbit of asteroid Dimorphos. Yet, new findings show that the collision sent boulders flying at speeds of 52 meters per second, posing challenges for future asteroid deflection efforts. This research underscores the critical need to grasp surface characteristics and debris dynamics for robust planetary defense.
