Abstract
Future missions to the Moon and Mars will require astronauts to live in sealed spacecraft and habitats where carbon dioxide (CO₂) can accumulate more easily than on Earth. However, the effects of moderate CO₂ levels in such environments are still not fully understood. To address this gap, a 7-day analog mission was conducted at the Analog Astronaut Training Center in Poland. Six crew members (five male, one female) lived inside a simulated international space station (ISS) habitat with artificial lighting, restricted airflow, and sustained moderately elevated CO2 (atmCO₂) (mean ~1120 ppm; peak 1200–1400 ppm). While physiological measures such as oxygen saturation and vital signs remained stable, participants reported changes in sleep, earlier waking, lower mood, and occasional symptoms like fatigue and headache. These findings suggest that behavioural and psychological domains may be more sensitive to moderate CO₂ exposure than traditional physiological markers, underscoring the importance of monitoring and mitigation in future missions. In the future, longer missions with larger crews will be needed to guide countermeasures and safety standards spacecraft and planetary habitats.
