Involves the capability to research, investigate and
characterize the effects of space flight and exposure to
microgravity, radiation, and other stresses on
physiological functions (e.g., musculoskeletal,
cardiovascular, etc.). In-depth understanding of the human
body, its physical and chemical make-up and the associated
technology and methods to examine the effects of various
environments and stresses. Ability to understand the
underlying physiological, behavioral and psychological
mechanisms and performance aspects responsible for
biomedical and behavioral changes in humans and animals
during spaceflight and apply this information to conduct
operational and clinical research to develop, and validate
countermeasures that will ensure the health, safety and
performance of flight crews involved during launches,
landings, and while in space.
