What makes Dragonfly unlike any mission NASA has flown before? Melissa Trainer, Dragonfly Deputy Principal Investigator at NASA's Goddard Space Flight Center, explains how Dragonfly combines the mobility of a helicopter with the scientific capabilities of a rover. By flying from site to site, the spacecraft can study Titan from above, then land to collect and analyze samples, giving scientists valuable geological context for every discovery. Dragonfly is a NASA mission, designed and built at Johns Hopkins APL, that will explore Titan in search of the chemical building blocks that could help scientists better understand the origins of life.
