Researchers followed 12 crew members for 10 months at Antarctica’s isolated Concordia Station to study how prolonged confinement affects teamwork. The study found increased conflict, distrust, perceptions of declining performance and the formation of subgroups during the mission. Scientists say the extreme isolation, limited social contacts and harsh environment make Antarctic stations useful analogues for long-duration spaceflight. The findings could help planners select crews and manage psychological risks on future missions to Mars.
