External Communication of Autonomous Crews Under Simulation of Interplanetary Missions

Two experiments, with 17-day and 120-day isolation, were carried out within the frame of the Scientific International Research in Unique Terrestrial Station (SIRIUS) international project at the Institute of Biomedical Problems (Moscow, Russia). Manifestations of the “detachment” phenomenon in the crew – mission control center (MCC) communication previously identified in the Mars-500 project were confirmed in this study. As in the Mars-500 experiment, in the SIRIUS-19, the landing simulation in the halfway of isolation caused a temporary increase of crew communication with MCC. We also revealed several differences in the communication styles of male and female crew members. By the end of the experiment, there was a convergence of communication styles of all the SIRIUS crew members and also an increase in crew cohesion.
