Purpose: Prolonged confinement during lunar habitation or Mars exploration, combined with limited communication and restricted emergency return options, can lead to significant mental stress due to constant interpersonal interactions and isolation from Earth. This mental stress has the potential to negatively impact the mission, making proper management essential. This study utilized functional near-infrared spectroscopy (fNIRS) to measure brain activity as a means of detecting mental stress. The aim was to evaluate brain activity changes in crew members who took part in the Scientific International Research In Unique terrestrial Station 21 (SIRIUS-21) mission. Method: fNIRS measurements were taken during cognitive tasks from six SIRIUS-21 crew members. The measurements were conducted six times: before entering the confined environment facility, during the stay (four times), and after exiting the facility. A two–channel fNIRS device was used to measure oxyhemoglobin absorption in the frontal region during the cognitive task. Results: Due to several measurement inaccuracies, only three crew members had more than two valid data points. No changes in average oxyhemoglobin concentrations were observed before, during, or after the cognitive tasks prior to confinement. However, during confinement, an increase in average oxyhemoglobin concentrations was observed during the cognitive tasks. Conclusion: For technical reasons, data from three crew members at two measurement points was included in the data processing. When comparing the oxyhemoglobin concentrations before and during confinement, we found that brain activity appeared to be more activated during confinement than before confinement. This suggests that prolonged confined environments may result in differences in brain activation.
