NASA’s Double Asteroid Redirection Test (DART) mission is a pioneering planetary defense initiative aimed at testing methods for preventing a potentially hazardous asteroid from colliding with Earth. Launched in November 2021, DART was designed to target the asteroid moonlet Dimorphos, which orbits the larger asteroid Didymos. The mission involved navigating a spacecraft to intentionally collide with Dimorphos at high speed in September 2022. This kinetic impact technique was intended to slightly alter the asteroid’s trajectory, demonstrating a viable method to deflect objects that could pose a future threat to Earth. The mission’s success was confirmed when telescopic observations showed that DART had successfully changed Dimorphos’s orbit around Didymos. This experiment marked the first time humanity has altered the dynamics of a celestial body in a measurable way, providing valuable data for developing strategies against potential asteroid threats.
