Astronauts may be celebrated for their physical endurance and technical expertise, but long-duration space missions push their mental health in ways that are far less visible. Living in confined quarters for months at a time, far from family and loved ones, astronauts often face isolation, monotony, and sensory deprivation that can heighten stress and anxiety. Sleep disruptions are common due to altered day–night cycles, while constant operational pressure and the awareness that mistakes can be fatal add layers of psychological strain. Communication delays with Earth can make emotional support feel distant, and crew dynamics, especially in small teams, can amplify tension or loneliness. Even highly trained astronauts with strong coping skills can experience mood shifts, lowered motivation, or difficulty regulating emotions. As space agencies plan for longer missions to the Moon and Mars, understanding and protecting astronauts’ mental well-being has become just as crucial as safeguarding their physical health.
