Behaviors of a mixed gender and culture group during a 4-month confinement (SIRIUS-19)

With a view to prepare human groups for long international and interplanetary missions, Scientific International Research in Unique Terrestrial Station (SIRIUS) program develops confinement campaigns whose SIRIUS-19 was 4-month duration. The goal was to simulate four phases of a mission including traveling to the Moon, orbiting the Moon, landing on the Moon, and returning to Earth. The Russian-American crew (n=6) consisted in 3 females and 3 males subjects. The ethological method for non-verbal and verbal behaviors analysis was based on observation, description and quantification of spontaneous actions, interactions, expressions and positions at meal time twice a month, and during group discussion, once a month. Results show expressive and communicative behaviors in female subjects, and less active but more interactive behaviors in male subjects, with specific adaptive strategies built by each ones. Crew cohesion follows a temporal dynamics. Discussion is on personal value and diversity value that contribute to the heterogeneous quality of a mixed gender and culture group in a positive way for space exploration success.
