Simulated Mars mission reveals isolation's impact on sleep and psychological well-being

A simulated Mars mission found isolation disrupted sleep and psychological well-being. Six volunteers endured 520 days in a mock spacecraft, experiencing altered circadian rhythms and mood fluctuations. These findings are crucial for future long-duration space travel planning. The MARS-500 experiment, conducted in 2010, highlighted the importance of astronaut mental health alongside engineering for interplanetary missions.
