Summary

In this presentation, Elizabeth Turtle and Ralph Lorenz provide an overview of NASA’s Dragonfly mission, a rotorcraft lander destined for Saturn’s moon Titan. The mission, selected in 2019 as part of the New Frontiers program, is scheduled for launch in July 2028 and arrival at Titan in 2034. Dragonfly aims to investigate Titan’s prebiotic chemistry, habitability, and geological processes. The vehicle is a multi-rotor drone that will fly between dozens of locations, using Titan’s dense atmosphere and low gravity to enable flight. The science payload includes a mass spectrometer, a gamma-ray and neutron spectrometer, meteorological and geophysical sensors, and cameras. The mission will land in the equatorial region near Selk impact crater, exploring dunes and interdunes to sample organic materials and potential water-ice mixtures. The presentation also covers engineering challenges, such as thermal design and autonomous navigation, and highlights the use of test facilities to simulate Titan’s environment. The talk concludes with a discussion of the mission’s potential for extended operations and the importance of Cassini-Huygens data in mission planning.
