SPACECRAFT LIFE SUPPORT SYSTEMS

Requirements of life support for the crew members considered in relation to man's metabolic requirements Appropriate methods and equipment are related to these characteristics of various manned space missions. Among the provisions required for maintaining physical well-being are systems for (1) the removal of carbon dioxide, (2) the reclamation and supplying of oxygen, (3) the control of temperature, humidity, and toxic gases, (4) the reclamation of water, (5) the management of wastes, and (6) the supplying of food.

Some of the research being performed at the Langley Research Center with life support systems is discussed and the research objectives are stressed. Descriptions are given of the various types of equipment used in this research, together with criteria for system evaluations.
