As NASA prepares for long-duration, crewed missions into deep outer space, it needs to have a better understanding as to why some individuals adapt and adjust better than others to the extreme demands of space living. Drawing upon evidence from multiple sources, the present report identifies the factors associated with individual differences in adaptability to isolated, confined and extreme (ICE) environments, and discusses implications for selection and sustainment of astronauts on long-duration missions. While the present results do not permit a rank-ordering of the relative importance of these variables, we are fairly confident that the most relevant variables are contained within this set. Based on this preliminary evidence, we discuss some implications for astronaut selection and training, and provide suggested countermeasures for preserving adaptability during long-duration missions. Additional research is needed to improve measurement strategies, verify causal directions, and understand the complex interactions and underlying processes involved in positive human adaptation to the physical and psychosocial challenges of life in deep space.

Operational interviews largely confirmed the findings from the systematic review, while providing additional information regarding factors that may contribute to individual adaptability for long duration missions. Operational experts agreed on the importance of intelligence (especially practical intelligence); emotional stability; openness; achievement orientation; optimism; control; hardiness; past experience; sleep; physical - biological factors; and positive coping strategies.

They also reinforced the mixed results on extraversion-introversion, indicating it is important to have a balance between introverted tendencies (e.g., maintaining privacy and emotional control), and extraverted ...
