Antarctica is considered one of the most reliable space analogs due to its extreme conditions: low temperatures, unstable geomagnetic environment, contrasting photoperiodicity and isolation.

Assessment of the functional state of the crew of the 67th and 68th Russian Antarctic Expeditions (RAE) at Vostok Station during long-term autonomous operations.

Participants in the 67th RAE maintained attention at baseline levels; reaction speed did not change, with declines in individual sessions compensated in subsequent ones (tests «Mark» and «NEO»); working memory capacity remained unchanged (test «Rainbow»). Participants in the 68th RAE showed increased information processing speed (test «NEO»); improved attention concentration (test «Zero»); and enhanced working memory (in the «Rainbow» test).

Considering the identified differences between groups from different expeditions, it is suggested to evaluate the motivational-volitional sphere of personality prior to deployment to predict the course of the expedition. Seasonal changes in Antarctic conditions have a significant but not decisive impact on test performance outcomes.

Based on the results obtained, it will be possible to better plan the expedition itself, as well as to adjust its work based on seasonality and duration. In the future, due to the comparable degree of autonomy and extreme conditions, the data can be extrapolated to preparations for future interplanetary missions.
