NASA's Dragonfly Mission Advances Towards Exploring Saturn's Moon Titan.

NASA's Dragonfly mission, which aims to explore Saturn's largest moon, Titan, using a rotorcraft-lander to investigate the moon's habitability, prebiotic chemistry, and potential signs of life, has passed a critical milestone. The weeklong Preliminary Design Review (PDR) involved more than 60 presentations and covered topics like spacecraft design, mission requirements, science plans, schedule, cost, and risk. The Dragonfly mission is the fourth in NASA's New Frontiers Program.
