Alicia Moreau de Justo 1500. C1107AAZ – Ciudad Autónoma de Buenos Aires, Argentina One of the most effective and complex concepts in planetary settlement is the integration of interfaces such as habitat modules, rover vehicles and space suits that can connect via airlocks, suitports and tunnels, and can disconnect to operate independently. This scenario is ideal to assess common symptoms during spaceflight missions such as fatigue, sleep loss, circadian desynchronization and work overload, This paper describes the main features of an integrated system built at the Human Spaceflight Laboratory from the Department of Space Studies at the University of North Dakota and a series of feasible measurements that can be conducted there to assess psychophysiological responses of a crew during confinement. This approach may contribute in the analysis of environmental mission conditions that interfere with sleep quality and individual vulnerabilities associated to sleep loss and circadian desynchronization. http://pubs.sciepub.com/ajmbr/3/4/5/ajmbr-3-4-5.pdf space medicine planetary outpost circadian rhythm sleep confinement
