Concept
Dragonfly (spacecraft)
Summary
Dragonfly is a planned spacecraft and NASA mission, which will send a robotic rotorcraft to the surface of Titan, the largest moon of Saturn. It would be the first aircraft on Titan and is intended to make the first powered and fully controlled atmospheric flight on any moon, with the intention of studying prebiotic chemistry and extraterrestrial habitability. It will then use its vertical takeoffs and landings (VTOL) capability to move between exploration sites.
Titan is unique in having an abundant, complex, and diverse carbon-rich chemistry on the surface of a water-ice-dominated world with an interior water ocean, making it a high-priority target for astrobiology and origin of life studies. The mission was proposed in April 2017 to NASA's New Frontiers program by the Johns Hopkins Applied Physics Laboratory (APL), and was selected as one of two finalists (out of twelve proposals) in December 2017 to further refine the mission's concept. On 27 June 2019, Dragonfly was selected to become the fourth mission in the New Frontiers program.
Dragonfly is an astrobiology mission to Titan to assess its microbial habitability and study its prebiotic chemistry at various locations. Dragonfly will perform controlled flights and vertical takeoffs and landings between locations. The mission will involve flights to multiple different locations on the surface, which allows sampling of diverse regions and geological contexts.
Titan is a compelling astrobiology target because its surface contains abundant complex carbon-rich chemistry and because both liquid water (transient) and liquid hydrocarbons can occur on its surface, possibly forming a prebiotic primordial soup.
A successful flight of Dragonfly will make it the second rotorcraft to fly on a celestial body other than Earth, following the success of a Martian technology demonstration UAV helicopter, Ingenuity, which landed on Mars with the Perseverance rover on 18 February 2021 as part of the Mars 2020 mission and successfully achieved powered flight on 19 April 2021.
