Objective We developed a conceptual framework of Team Self-Maintenance (TSM) within long-duration space exploration (LDSE), which we define as the process of monitoring, adjusting, and maintaining the psychological well-being of a team in the absence of external support. Background Specific to LDSE and isolated, confined, and extreme (ICE) environments, periods of routine can have a debilitating effect on the crew’s well-being and performance, and TSM is a critical process for avoiding these detrimental effects. Method Based on themes drawn from nine subject matter expert interviews combined with an extensive literature review on related concepts, we developed an integrative conceptual framework of the key inputs, processes, and outputs involved in TSM within LDSE contexts. Results Our TSM framework suggests team well-being as a key outcome that must be maintained during LDSE and information sharing, self-regulation, resource recovery, and emotional support as the key processes that enable team well-being. We also identify several contextual inputs that can serve as intervention points for enabling effective TSM. Conclusion Our framework suggests that future research and practice aimed at effective LDSE should emphasize team well-being, rather than just performance, and that there are many open questions in terms of how teams will manage their own socio-emotional needs (e.g., conflict, recovery activities, and boredom) without external systems and support. Application This conceptual framework describes the primary inputs, processes, and outcomes involved in the team self-maintenance process. This framework reflects context-specific theorizing most likely to be applicable only to LDSE contexts.
