NASA to launch Dragonfly drone to Saturn's moon Titan in 2028

NASA plans to launch Dragonfly, a car-sized nuclear-powered drone, to Saturn's moon Titan later this decade. The mission will explore Titan's methane lakes and dunes, searching for signs of life. Titan is the only world besides Earth with stable surface liquids.
Titan's Earthlike Landscape
Titan is the only world besides Earth known to have stable liquids on its surface, with a temperature of minus 179 degrees Celsius. Methane and ethane form a weather cycle similar to Earth's water cycle, producing clouds and rain that flow into lakes and seas. Measurements from NASA's Cassini mission indicated some northern lakes exceed 100 meters in depth. Planetary scientist Alex Hayes described Titan as "an explorer's utopia."
Flight on Titan
Titan's dense atmosphere and low gravity make powered flight efficient. Dragonfly will use eight rotors in four pairs, powered by a Multi-Mission Radioisotope Thermoelectric Generator that converts heat from plutonium-238 decay into electricity. The batteries will supply power for flights and science operations, while waste heat keeps equipment warm. A Titan day lasts 16 Earth days, and Dragonfly could travel up to 175 kilometers during its mission.
What's Next
NASA is targeting a launch later this decade, with Dragonfly expected to arrive at Titan in the mid-2030s. It remains unclear whether the drone will find evidence of prebiotic chemistry or life on the moon.
