NASA's Dragonfly Mission: Nuclear-Powered Drone to Explore Saturn's Moon Titan in 2028

NASA is preparing to launch the Dragonfly mission in July 2028, a car-sized, plutonium-powered drone destined for Saturn's moon Titan. The $3.35 billion mission will take six years to reach Titan, arriving in 2034. Unlike previous rovers, Dragonfly is a rotorcraft designed to fly through Titan's dense atmosphere, which is four times thicker than Earth's, with gravity only one-seventh as strong. The 1,000-pound vehicle uses eight rotors and a Multi-Mission Radioisotope Thermoelectric Generator (MMRTG) for power, as sunlight is too weak nearly 900 million miles from the Sun. Over more than three years, Dragonfly will autonomously hop between dozens of sites, using instruments like a mass spectrometer and gamma-ray spectrometer to analyze organic molecules and search for prebiotic chemistry. The mission represents a major shift in planetary exploration, demonstrating aircraft as standard tools on worlds with atmospheres.
