NASA’s DART mission successfully deflected an asteroid but also unleashed high-velocity boulders with unexpected momentum. These chaotic ejecta may alter asteroid spin and orbit, complicating future deflection strategies. A new study highlights the importance of accounting for such forces in planetary defence.
