Jani Radebaugh | Dragonfly: Explorer for Saturn's Moon Titan | NEAF Talks
Filmed April 2020
Who is Jani Radebaugh?
JANI RADENBAUGH is a planetary scientist who specializes in field studies of planets. She’s a regular presence on the Science/Discovery program How the Universe Works, the NASA Unexplained Files, and other BBC and Nova programs. She is an Associate Team Member of the Cassini RADAR instrument and is a Science Team Member for the newly selected Dragonfly rotorcraft lander mission to Saturn’s moon Titan. She was also involved in the Galileo Mission, the Io Volcanoes Observer mission proposal, and the Median project for Mars. Professor Radebaugh believes exploring Earth is our best chance at fully understanding the other planets in our solar system. She travels far and wide with her Brigham Young University geology students to find and study unique
landscapes. She explores the big deserts of the world, such as the Saharan, Arabian, and Namib deserts, as well as the Argentinian Altiplano and Iran’s Lut desert to study giant sand dunes and wind-carved ridges similar to features on Titan, Mars, Venus, and Pluto. She visits the lava lakes of the world, such as those in the Ethiopian Afar valley and Vanuatu in the southwest Pacific, to compare them with active lava lakes of
Jupiter’s moon Io.
Saturn’s largest moon Titan, as seen by the Cassini mission, is an Earth-like world in many ways, having river channels, lakes, vast sand dunes, and a nitrogen-rich, dense atmosphere. Yet the temperature is 90 degrees above absolute zero, the surface liquid is methane, the crust is water ice, and the dunes are made of organic sands. Sometimes conditions may be right such that complex organic materials, such as in the sand dunes, can combine with liquid water, thus being favorable for life. The newly selected, $1 billion NASA mission Dragonfly, now in design, is a quadcopter-like rotorcraft lander for Titan. This capable spacecraft will image the surface up close, in the vein of Mars rover exploration, but could vastly outstrip these rovers in ground coverage, easily exceeding several hundred miles. And it will analyze samples, helping us understand if conditions are right for life in the distant reaches of our solar system.
NEAF Talks brings you the best from the annual NEAF Space & Astronomy conference which is held just outside of New York City at the RCC campus of the State University of NY. The Northeast Astronomy Forum is in its 30th year and is a world-renowned symposium that annually searches the globe for the most relevant personalities who are making space, science, and astronomy history today. Now through NEAF Talks online, these outstanding lectures are available to classrooms, universities, professionals, and the world at large free of charge.
