Physical and Bioenvironmental Aspects of Human Space Flight

This chapter is intended as an overview of the basic body of information required of the space medicine practitioner to understand the adaptive and operational environment of space flyers. An understanding of the physiologic and medical implications of this environment enables the practitioner to provide optimal medical support. This information should provide a foundation for discussions of physiologic and psychological processes associated with space flight and allow the response to medical events to be placed in proper context. Understanding this context also prepares the spaceflight surgeon to serve as a consultant in space program organizations, where human needs must fit into mission parameters and priorities.
