ISS Science for Everyone

Science Objectives for Everyone
Study of small group (space crew) behavioral laws throughout long-duration space flight.
Science Results for Everyone
Keeping the “international” in the International Space Station. Crew members’ personal and cultural differences and group dynamics can affect mission success. This investigation tested group dynamics, stress, and relationship changes in order to optimize crew selection, training, and support. Significant changes happened during the first month, little change during the next four months, and more significant change again in the final month. This confirmed that stress at various stages of long-term flight causes a partial change in self-perception and perception of others. The data also confirm the relevance of studying psychological similarity of crew members and taking into account the number of crew and their nationalities.

Results/More Information

In order to fulfill the approved objectives of the experiment, it is necessary to study at least 20 ISS crew members. Scientific analysis of the results is performed upon accumulation of sufficient amount of data for statistical analysis in order to determine general patterns of group dynamics in an international ISS crew.

It is shown that the most marked changes took place over the course of the first month of flight. During the following 4 months of the increment, assessment oneself remained virtually unchanged. During the last month of flight, more marked changes describing communication, mood, and self-control come to the foreground. Thus, the results obtained confirm the proposed hypothesis that under the influence of stress at various stages of long-term spaceflight, a partial change takes place in self-perception and perception of other crewmembers, including the most significant criteria reflecting the person's basic values. Experimental data confirm the high significance and relevance of studying the degree of psychological closeness (similarity) of members of an international space crew, particularly taking into account the specific features of the current phase of work on the ISS, which are characterized by an increased number of cosmonauts and astronauts and their different nationalities.
