“Titan: Ingredients for Life”

ABSTRACT

NASA's Cassini mission has revealed Saturn's larger moon Titan to be a world rich in the “stuff of life.” Reactions occurring in its dense nitrogen-methane atmosphere produce a wide variety of organic molecules, which subsequently rain down onto its surface. If these molecules mix with water found in cryovolanic lavas or impact melts on Titan's surface, they may react to form biological molecules such as amino acids. The prebiotic reactions occurring on Titan are intriguingly similar to reactions that may have occurred on the early Earth, and provide clues to the origin of life on our own world and worlds throughout the universe. In this presentation, I will report on the ideal locations for identifying biological molecules on Titan’s surface, and describe the Dragonfly mission concept for studying Titan as a habitable world.
