Long-duration space missions reveal negative emotions displaced between crew and mission control. Interpersonal climate varied by nationality and role, with mission control reporting more tension.

Area of Science:

  • Space psychology
  • Human factors in aerospace
  • Interpersonal dynamics in extreme environments

Background:

  • Understanding interpersonal dynamics is crucial for long-duration space missions.
  • Factors influencing crew and mission control interactions require investigation.

Purpose of the Study:

  • To evaluate emotion displacement, changes in group climate, and cultural differences during space missions.
  • To analyze interpersonal factors affecting crew and mission control during the Shuttle/Mir program.

Main Methods:

  • Weekly questionnaires assessing mood and group climate (Profile of Mood States, Group and Work Environment Scales).
  • Critical incident logs collected from astronauts, cosmonauts, and mission control personnel.
  • Informed consent obtained from 5 astronauts, 8 cosmonauts, and 58 mission control personnel.

Main Results:

  • Evidence of negative emotion displacement from crew to mission control and from mission control to management.
  • Decreased commander support noted in the latter half of missions; American crew experienced a novelty effect.
  • Mission control personnel reported higher tension and dysphoria than crewmembers; cultural differences observed between American and Russian participants.

Conclusions:

  • Interpersonal climate is significantly impacted by role, duration, and cultural background.
  • Emotion displacement and perceived support are key factors in space mission well-being.
  • Findings offer insights for optimizing psychological support in future long-duration spaceflight.
