Medical and Biological Problems of Space Flight covers the proceedings of the conference held in Nassau, the Bahamas. The book focuses on the biological and medical problems of space flight, as well as advanced manned space systems, cardiovascular adaptability, weightlessness, and remote visual monitoring. The selection first offers information on the development of manned space vehicles and advanced manned space systems, including manned satellite and space stations, safety considerations, and man-machine aspects. The book also takes a look at Marsflight II space cabin simulator and device for simulating weightlessness. Discussions focus on the psychological aspects of real and simulated weightlessness; physiological effects of real and simulated weightlessness; and critique of simulation excellence. The publication examines maintenance of cardiovascular adaptability during prolonged weightlessness and the physical, biological, and medical aspects of weightlessness. The text then ponders on remote visual monitoring during extended space missions and cosmic ray shower production in manned space vehicles. Topics include electron-proton showers and limitations imposed by communications on transmission of pictorial information from a space vehicle. The selection is a valuable reference for readers interested in the medical and biological problems of space flight.
