Crew with ‘Diversity’ of Personalities Would Be Best Mars Mission Team: Study

Not all alphas: Mars crews should be a mix of personality types, study suggests

A new study indicates that crews with a wider range of personalities perform better under pressure, possibly informing how NASA selects and trains its astronauts for future missions to Mars.

Crew with ‘diversity’ of personalities would be best Mars mission team: study

A research team modeled how personality traits influence stress responses during long-duration missions for the first time.

Computer models point to crew diversity as key to resilient Mars missions

Los Angeles CA (SPX) Oct 09, 2025 Simulation results from Stevens Institute of Technology researchers Iser Pena and Hao Chen indicate that who you send to Mars matters as much as what you send. Published October 8, 2025 in PLOS One, the study used agent-based modeling to probe how personality mix and team roles shape stress, health, performance, and cohesion over a simulated 500-day mission. The model linked individual dif

Selecting Teams for Mars Missions

In an era where humanity’s gaze is firmly fixed on the red planet, understanding the complex social dynamics of astronaut teams during prolonged space missions has become a scientific imperative. A groundbreaking study published in the open-access journal PLOS One on October 8, 2025, offers unprecedented insights into how personality diversity among crew members can […]
