The science of sleep in space

How do astronauts get quality sleep in space? Erin Flynn-Evans, director of the Fatigue Countermeasures Laboratory at NASA Ames Research Center, joins Planetary Radio to explore how her team studies sleep, fatigue, and circadian rhythms to keep astronauts healthy and mission-ready. She shares how her team translates sleep science into actionable strategies for NASA crews, and how a chance job as a sleep technician led her on a path to spaceflight research.

Later in the show, Casey Dreier, The Planetary Society’s chief of space policy, and Jack Kiraly, our director of government relations, provide a quick update on NASA’s budget and what it means for the agency’s future. Then, Bruce Betts, our chief scientist, joins us for What’s Up to explore how and why our robotic spacecraft sometimes need to power down and rest.
