The model linked individual differences across the Big Five traits to mission roles such as engineer, medic, and pilot, then tracked emergent team outcomes under isolation and workload. Heterogeneous crews generally outperformed homogeneous ones, with combinations like high conscientiousness paired with low neuroticism, or high extraversion alongside high agreeableness, associated with lower stress and stronger cohesion and performance.
The authors emphasize constraints, including the assumption that traits remain fixed, but argue the findings can guide astronaut selection by integrating personality assessments with skills to build complementary teams. They add that NASA's Artemis era and concrete Mars planning heighten the need for predictive tools that capture human factors under realistic conditions.
The team concludes with two statements: "For the first time, we've combined psychological insights with a computer simulation to model a 500-day mission to Mars." "This new approach lets us explore how different astronaut personalities and team roles might affect a crew's stress and performance, and it gives us a glimpse of the human challenges astronauts could face on these long journeys into deep space."
