Ever wondered how NASA studies what life would be like in deep space without leaving Earth? Conversations between past crews in NASA’s Human Exploration Research Analog (HERA) and curious students shed light on missions that simulate the isolation and confinement felt by astronauts.

HERA crew members helped scientists learn more about how isolation, confinement, and remote conditions will affect astronauts on Artemis missions to the Moon and on future missions to Mars. Watch the most recent Groundlink episodes above and scan other episodes below.

NASA’s Human Research Program pursues methods and technologies to support safe, productive human space travel. Through science conducted in laboratories, ground-based analogs, and the International Space Station, this team scrutinizes how spaceflight affects human bodies and behaviors. Such research drives NASA’s quest to innovate ways that keep astronauts healthy and mission-ready as space travel expands to the Moon, Mars, and beyond.
