DART Alters Didymos System’s Solar Orbit, Validates Kinetic-Impactor Planetary Defense

NASA's DART mission deliberately altered the Didymos binary system's orbit around the Sun, demonstrating that a kinetic impactor can measurably change an asteroid's trajectory and serve as an effective planetary-defense tool for deflecting near-Earth objects. The result validates kinetic-impact techniques used in deflection planning.
