External Communication of Autonomous Crews Under Simulation of Interplanetary Missions

Area of Science:

• Space Medicine and Human Factors
• Psychology of Extreme Environments

Background:

• Previous Mars-500 project identified a "detachment" phenomenon in crew-mission control communication.
• Understanding crew communication dynamics is crucial for long-duration space missions.
• The Scientific International Research in Unique Terrestrial Station (SIRIUS) project investigates human adaptation to isolation.

Purpose of the Study:

• To confirm the "detachment" phenomenon in crew-mission control communication during SIRIUS isolation experiments.
• To analyze communication patterns, including gender differences, during simulated space missions.
• To assess the impact of a simulated landing event on crew communication and cohesion.

Main Methods:

• Conducted two isolation experiments (17-day and 120-day) within the SIRIUS international project.
• Monitored and analyzed crew-mission control center (MCC) communication patterns.
• Introduced a simulated landing event midway through the isolation period.

Main Results:

• Confirmed the "detachment" phenomenon, with a temporary increase in crew-MCC communication during the simulated landing.
• Observed distinct communication style differences between male and female crew members.
• Reported a convergence of communication styles and increased crew cohesion by the experiment's end.

Conclusions:

• The "detachment" phenomenon is a recurring aspect of long-duration space mission simulations.
• Crew communication styles evolve during isolation, influenced by events and potentially gender.
• Increased crew cohesion and communication convergence suggest successful adaptation to the isolated environment.
