Bioastronautics: Definition and Scope
Bioastronautics is the intersection of space science and technology with biology and human factors. It encompasses both human and nonhuman space life science, including astronaut performance, protection, and life support as well as the effect of space on biological processes.
Bioastronauticsis the area of science and technology at the boundary of life science and space technology. It encompasses the special influence of space travel on biology, including physiology and medicine. Extended weightlessness, inherent in orbital flight, leads to well-documented physiological deconditioning. Bones, muscles, cardiovascular responses, and the control of posture and balance all suffer from the absence of a steady gravitational pull. The immune system and metabolism show their own reactions to “zero-G.” Reduced gravity, including the 1/6 G of the moon and the 3/8 G of Mars, could cause physiological deconditioning for extended missions – although data is currently unavailable for...
