Four NASA astronauts "returned" from Mars - they spent more than a year in isolation Four participants in NASA's Mars simulation experiment completed a mission of 378 days in isolation. They left a specially equipped residential module at the Johnson Space Center in Houston, where since October 2025 they have been studying how prolonged exposure to confined spaces and confined conditions affects the health, performance and psychological state of the crew. The experiment should help prepare for future manned missions to Mars. The difference between this experiment was the composition of the predominantly male team; In the first, the gender composition was equal.
