Titan is the only moon in our solar system with a dense atmosphere, which supports an Earth-like hydrological cycle of methane clouds, rain, lakes, and seas. Complex organic surface materials may preserve, in a deep freeze, the types of organic chemicals that would have been present on Earth before life developed. Titan’s icy crust floats atop an interior liquid water ocean. The Dragonfly mission to Titan will characterize its habitability and determine how far prebiotic chemistry has progressed in environments known to provide the necessary ingredients for life. The mission comprises a single rotorcraft lander with a sophisticated scientific payload, designed to take advantage of Titan’s environment, and achieve wide-ranging exploration by flying to sites in different geologic settings. Launching in 2027 and reaching Titan in the mid-2030s, Dragonfly will journey farther than any robotic lander has ever traveled. The rotorcraft will travel from its initial landing site to cover areas several dozen kilometers away during the planned ~3-year mission.
