Tangerine Dream: Titan’s Diverse Environments

Session ID#: 162209

Session Description:
Titan is the only moon in the Solar System with a dense atmosphere. It is an Ocean World, with an interior liquid water layer that may provide an abode for life. Photochemistry in the stratosphere consumes methane and generates complex organic molecules, perhaps analogous to the atmospheric chemistry of prebiotic Earth, and in the present-day atmospheres of exoplanets.  Methane meteorology in the lower atmosphere leads to rivers, seas, clouds and rain in a weather cycle analogous to that on Earth. The surface has few craters, but exhibits mountains, dune fields and other mysterious landforms that may be evidence for ongoing tectonism. Titan has been highlighted as an important destination for future exploration in the 2022 Decadal Survey for Planetary Sciences, including NASA’s Dragonfly mission, and a possible future Titan Orbiter. In this session we welcome new research relevant to Titan, including observations, spacecraft data analysis, modeling and laboratory experiment work. We also welcome abstracts that discuss relevance of Titan observations to exoplanet studies.
