Analogue prototypes for Lunar and Mars exploration.

Small groups living and working in isolation and confinement experience unique stressors that have predictable effects on individual adjustment and performance. Because the stress is cumulative, long-duration missions impose considerable burdens on an individual's capacity to adjust to the conditions and to perform well, both technically and socially. This paper describes research conducted to extrapolate design and procedural guidelines for lunar and planetary expeditions from a review of information concerning previous expeditions and voyages of discovery.
