Culture, Values and Environmental Adaptation in Space [At Home in Space (Ax-1)] on the Axiom-1 (Ax-1) private astronaut mission (PAM) assesses culture, values, and psychosocial adaptation of astronauts to sharing a space environment with multinational crews. Whether crew members feel at home in space and develop a shared space culture could affect the success of future long-duration missions. Ax-1 crew members complete a questionnaire battery before, during, and after flight to evaluate individual and culturally-related differences, family functioning, coping with stress, and post-experience change.
