Rank 21 documents DART — the Double Asteroid Redirection Test, the first planetary defense demonstration that confirmed a kinetic impactor could alter an asteroid's orbit. Launched 24 November 2021 aboard Falcon 9, DART travelled to the binary Didymos system and struck Dimorphos at 6.1 km/s on 26 September 2022, shortening the moonlet's orbital period around Didymos by 32 minutes — a result measured by ground telescopes and the LICIACube witness cubesat. Andy Rivkin and Nancy Chabot's APL/JPL teams operated the DRACO imager as DART's sole science payload, while NEXT-C ion thrusters handled cruise propulsion. Wallimilist renders the gold-foil DART bus at impact moment, Didymos ejecta plume, golden orbital circle frame, and cream DART trapezoid title exactly as the master PNG dictates — Planetary Defense line, italic deflection kicker, and curator copy on kinetic impact heritage.
