NASA's simulated Mars mission crew emerges after 378 days in isolation

Four crew members who took part in NASA's simulated Mars mission have emerged after spending 378 days in isolation at the US space agency's Johnson Space Center in Houston. They entered a 1,700-square-foot, 3D-printed habitat on October 19, 2025. Their tasks included growing crops in simulated Martian soil and communicating with NASA officials through delays mimicking interplanetary communication.
