flag NASA’s DART mission successfully altered asteroid Dimorphos’ orbit, proving kinetic impact can deflect asteroids.

flag NASA’s DART mission successfully altered the orbit of asteroid Dimorphos around the sun, marking the first time humanity has deliberately changed a celestial body’s path. flag The spacecraft collided with Dimorphos in September 2022, reducing its orbital period by 0.15 seconds and shifting its trajectory by about 2,360 feet over two years. flag Scientists confirmed the change using global telescope observations, validating kinetic impact as a viable planetary defense strategy. flag The impact ejected an estimated 35 million pounds of debris, doubling momentum transfer. flag Researchers emphasize that early, small deflections are far more effective than last-minute interventions. flag The European Space Agency’s Hera mission, arriving in November, will study the aftermath in detail.
