Man in space.
The Challenger disaster focused attention on the hazards as well as the possibilities of man in space.  The physiological effects of prolonged weightlessness include important changes in vestibular, bone, muscle, cardiovascular, blood, renal, and pulmonary function.  Much has been learned from US and Soviet experiments, but large areas of ignorance remain.  Exceptional opportunities for physiological research are provided by Spacelab, a pressurized laboratory planned as a payload of the Space Shuttle.
