Elizabeth Turtle, Ph.D.Planetary Scientist, Johns Hopkins Applied Physics Laboratory, Johns Hopkins University
Presidential Lectures are a series of free public colloquia spotlighting groundbreaking research across four themes: neuroscience and autism science, physics, biology, and mathematics and computer science. These curated, high-level scientific talks feature leading scientists and mathematicians and are designed to foster discussion and drive discovery within the New York City research community. We invite those interested in these topics to join us for this weekly lecture series.
Saturn’s largest moon, Titan, is a world surrounded by a dense atmosphere with abundant complex organic material on its surface and a liquid-water ocean in its interior. These properties make Titan a singular destination to seek answers to fundamental questions about the origins of life: What makes a planet or moon habitable? What chemical processes led to the development of life?
In this lecture, Elizabeth Turtle will discuss discoveries about Titan made by the Cassini-Huygens mission. She will also present the Dragonfly mission concept for future exploration of this unique world by rotorcraft. Titan has been revealed to be surprisingly Earth-like, with active geological processes and opportunities for organic material to mix with liquid water on the surface. Dragonfly, which is being studied under NASA’s New Frontiers program, would take advantage of Titan’s dense atmosphere and low gravity to fly from place to place to measure compositions of surface materials and observe Titan’s geology and meteorology. Aerial mobility enables Dragonfly to explore dozens of diverse landing sites. Traveling tens to hundreds of kilometers over its two-year mission, Dragonfly will investigate the habitability of this extraterrestrial environment and chemical processes like those that supported the development of life on Earth.
About the Speaker
Turtle is a planetary scientist at the Johns Hopkins Applied Physics Laboratory with expertise in spacecraft exploration of the solar system. She has participated in the Galileo, Cassini, and Lunar Reconnaissance Orbiter missions, and is the Principal Investigator (PI) for the Europa Imaging System (EIS) on Europa Clipper and for the Dragonfly mission concept being studied under NASA’s New Frontiers Program. She earned a B.S. in physics at MIT and a Ph.D. in planetary sciences at the University of Arizona in Tucson.
