title: Medical concerns for exploration-class missions.
abstract: The Space Exploration Initiative will challenge life scientists with a diverse set of crew medical risks. The varied sources of this cumulative risk are identified and briefly discussed in terms of risk assessment and preliminary plans for risk management. The roles of Space Station Freedom and other flight programs are discussed in the context of exploration medical objectives; and the significant differences between Space Station era (second generation) and exploration medical support systems (third generation) are reviewed.
