Psychosocial interaction during a 105-day isolated mission in LUNAR PALACE 1

As the most important and critical group in space missions, crew's emotions and interpersonal interactions have gained attentions. Confined isolated environment, limited communication with outside and unpredictable risks may lead to the aggravation and acceleration of depression, displacement and interpersonal conflictions, which can deteriorate astronauts' effectiveness and safety. Therefore, the aim of the study is to identify possible change rules over time of emotional states, cohesion and other group dynamics in 105-day isolation period. The experiment is conducted in an analogue space station in Beihang University called LUNAR PALACE 1. In our experiment, all crewmembers and mission control personnel will complete a questionnaire named profile of mood states (POMS) every week and two group climate scales every two weeks, which are the group environment scale (GES) and the work environment scale (WES). After the experiment isolation period interviews will be conducted too. As a result, we found that: i) There was no 3^rd quarter phenomenon in LUNAR PALACE 1; ii) Significant individual differences and gender differences were identified. Female crewmember perceived more positively than male crewmember; iii) The post-mission interview results were consistent with questionnaires. In summary, the results from LUNAR PALACE 1 demonstrated that emotions and group climate of group 3 were in a relatively good state.
