PSW 2397 Dragonfly: Exploring Titan by Rotorcraft | Zibi Turtle
Published on Oct 9, 2018

Titan exhibits abundant complex organic compounds on the surface of a water-ice-dominated ocean world with Earth-like geologic and atmospheric exchange processes. In addition to the level of organic synthesis that Titan supports, there have also been opportunities in Titan's past for organics to have mixed with liquid water on Titan's surface, for example at sites of cryovolcanic activity or impact melting. Such interactions increase the potential for chemistry to have progressed beyond simple organic reactions, providing an unparalleled opportunity to study prebiotic chemistry, and to search for signatures of potential water-based and hydrocarbon-based life. Thus, Titan is an ideal destination to seek answers to fundamental questions about the origins of life, such as: What makes a planet or moon habitable? What chemical processes led to the development of life?
While the now completed Cassini mission discovered that the chemical reactions in Titan's upper atmosphere generate much more complex organic molecules than had been expected, the compositions of the solid materials on Titan's surface remain essentially unknown, and the spacecraft revealed substantial compositional diversity across Titan's surface. Therefore it will be key for a future mission to be able to measure surface material compositions at a variety of locations: mobility will be essential.
This lecture will discuss the Dragonfly mission concept under study in NASA's New Frontiers Program. Dragonfly is a rotorcraft lander that would take advantage of Titan's dense atmosphere and low gravity to use aerial mobility for wide-ranging in situexploration of Titan's surface and atmosphere. Dragonfly's ability to fly will enable it to access different geologic settings 10s to 100s of kilometers apart, allowing Dragonfly to perform multidisciplinary science at multiple, diverse landing sites. In its two year plus mission, Dragonfly's revolutionary mobility will allow it to characterize prebiotic chemistry and habitability at dozens of diverse sites across Titan and to search for water- and hydrocarbon-based chemical biosignatures at each one.
Elizabeth (Zibi) Turtle is a planetary scientist at the Johns Hopkins Applied Physics Laboratory. She is the Principal Investigator of the Europa Imaging System (EIS) on Europa Clipper and Principal Investigator of the Dragonfly mission concept currently in competition under NASA's New Frontiers Program. Zibi also is an associate of the Cassini ISS and RADAR teams, a Co-Investigator of LROC on the Lunar Reconnaissance Orbiter. Previously she was an associate of the Galileo SSI team.
Zibi's research combines remote-sensing observations and numerical modeling, focusing in particular on impact cratering and tectonics on satellites and terrestrial planets, and on lakes and weather on Titan.
Zibi earned a BS in Physics at MIT and a PhD in Planetary Sciences at the University of Arizona.

In under an hour, the Dragonfly dual-quadcopter could cover tens of miles on Titan, Saturn's largest moon. That's farther than any planetary rover has traveled! With one hop per full Titan day (16 Earth days), the rotorcraft would travel from its initial landing site to cover areas several hundred kilometers away during the planned two-year mission. Dragonfly is a JHUAPL mission under NASA's New Frontiers Program.

The science of Dragonfly

Dragonfly is a NASA mission to explore the chemistry and habitability of Saturn's largest moon, Titan. The fourth mission in the New Frontiers line, Dragonfly will send an autonomously-operated rotorcraft to visit dozens of sites on Titan, investigating the moon's surface and shallow subsurface for organic molecules and possible biosignatures. To carry out its mission, Dragonfly is equipped with a neutron spectrometer, a drill system, and a mass spectrometer, allowing scientists to make a detailed survey of Titan's chemical makeup. Dragonfly is scheduled to launch in 2026 and arrive at Titan in 2034.
