Outer space medicine and relevant ongoing biomedical research.

Abstract

An update of outer space medicine is given emphasizing main areas such as cardiopulmonary responses, vestibular functions, physiology, weightlessness, ecosystems, and radiation. A prospective view is also presented on the medical problems resulting from various hazards of outer space and planetary missions. Although an outgrowth of aviation and environmental medicine, this relatively new, special branch of medicine is currently undergoing an unprecedented rise as a vital modern specialty. The aims of the United States, Russia, and the nations of Europe in space research are shown to be in accord in learning how to live and work in space when confronted with the unique factors of zero gravity, cosmic radiation, and magnetic variations.
