An investigation with Portuguese participation followed a crew isolated in Antarctica for almost a year, with the objective of understanding the psychological challenges of living in extreme environments. The study was part of a broader effort to anticipate the problems that will be faced by future long-duration space missions.
The researchers discovered that as Winter progressed, the forced proximity between crew members did not have the effect of uniting the team, as would be expected. Instead, prolonged cohabitation ended up creating divisions and tensions among group members.
This conclusion represents a significant obstacle for plans to establish human colonies on the Moon or Mars, where astronauts would have to live confined in small spaces for very long periods. The Earth-Mars journey, for example, can take about nine months, which would make managing interpersonal relationships a fundamental challenge.
The results of this study suggest that the selection and training of crews for long-duration space missions should pay special attention to group dynamics and conflict management strategies, beyond the technical skills of astronauts.
