Simulation background
Researchers created a computer model that runs multiple scenarios for a permanent lunar outpost. The model evaluates operational workflows, resource consumption, and emergency procedures alongside psychological considerations.
Findings on crew size
The study suggests that a core crew of four to six astronauts balances workload and life‑support requirements. Teams smaller than this increase individual strain, while larger groups would cause disproportionate demands for food, water and oxygen.
Role of mission design
Key determinants of the ideal crew size are the planned activities: scientific research, maintenance, construction and contingency response. Scenarios with high automation allow for smaller crews, whereas a greater share of manual tasks necessitates more personnel.
Implications for Artemis and future programs
The results are being integrated into NASA's Artemis program, which aims to establish a sustained presence on the Moon by the end of the decade. The study stresses that crew‑size decisions must be made early in the design phase to optimize infrastructure and logistics.
Future work
Additional research will examine the interaction between psychological stressors and operational demands to provide a comprehensive framework for crew planning.
