NASA’s DART mission successfully altered asteroid Dimorphos’ orbit, proving kinetic impact can deflect asteroids.
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.
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.
Scientists confirmed the change using global telescope observations, validating kinetic impact as a viable planetary defense strategy.
The impact ejected an estimated 35 million pounds of debris, doubling momentum transfer.
Researchers emphasize that early, small deflections are far more effective than last-minute interventions.
The European Space Agency’s Hera mission, arriving in November, will study the aftermath in detail.
