They locked them up for 378 days to live like on Mars. "It was a hellishly difficult year"

NASA has completed a simulated Mars mission lasting 378 days to study human adaptation to isolation and Mars-like conditions. Participants engaged in tasks such as plant cultivation and maintenance of their habitat, designed to mimic life on Mars. The experiment aimed to prepare astronauts for future missions by understanding the challenges of long-duration space travel, including communication delays. NASA plans to conduct more missions under the CHAPEA program to gather data on astronaut health and performance. The insights gained will inform preparations for manned missions to Mars, expected in the 2030s.
