Cultural differences in crewmembers and mission control personnel during two space station programs.

摘要

INTRODUCTION: Cultural differences among crewmembers and mission control personnel can affect long-duration space missions. We examine three cultural contrasts: national (American vs. Russian); occupational (crewmembers vs. mission control personnel); and organizational [Mir space station vs. International Space Station (ISS)]. METHODS: The Mir sample included 5 American astronauts, 8 Russian cosmonauts, and 42 American and 16 Russian mission control personnel. The ISS sample included 8 astronauts, 9 cosmonauts, and 108 American and 20 Russian mission control personnel. Subjects responded to mood and group climate questions on a weekly basis. The ISS sample also completed a culture and language questionnaire. RESULTS: Crewmembers had higher scores on cultural sophistication than mission control personnel, especially American mission control. Cultural sophistication was not related to mood or social climate. Russian subjects reported greater language flexibility than Americans. Crewmembers reported better mood states than mission control, but both were in the healthy range. There were several Russian-American differences in social climate, with the most robust being higher work pressure among Americans. Russian-American social climate differences were also found in analyses of crew only. Analyses showed Mir-ISS differences in social climate among crew but not in the full sample. DISCUSSION: We found evidence for national, occupational, and organizational cultural differences. The findings from the Mir space station were essentially replicated on the ISS. Alterations to the ISS to make it a more user-friendly environment have still not resolved the issue of high levels of work pressure among the American crew.
