NASA's DART mission ejected boulders from asteroid Dimorphos, offering new insight into asteroid collision outcomes

NASA's DART mission successfully altered Dimorphos' orbit, but the impact unleashed over 100 boulders, significantly boosting momentum transfer. These ejected rocks, captured by LICIACube, carried nearly as much momentum as DART itself, revealing the importance of considering debris ejecta in future asteroid redirection efforts. The European Space Agency’s Hera mission will further investigate these effects.
