Researchers at George Mason University have developed a virtual model to simulate how astronauts might interact with each other and their environment during future lunar missions. The agent-based simulation, published in PLOS One, incorporates cognitive, social, emotional, and environmental factors to predict how teams might adapt under the extreme conditions of a Moon base. Virtual astronauts are assigned varying skills, personalities, and health traits, then exposed to routine tasks and unexpected events like moonquakes and equipment failures.

The simulations ran tens of thousands of scenarios, revealing that larger crews improved skill development and personality compatibility, boosting teamwork. However, longer mission durations and lack of crew rotation increased psychological stress, reducing overall mission effectiveness. These findings suggest that human factors are as critical as engineering in planning sustainable lunar outposts.

The model could help NASA and other space agencies optimize crew selection and mission design ahead of the Artemis program’s goal of establishing a permanent Moon base. Future improvements may include modeling physiological effects of deep space and communication delays with Earth.
