First sentence: Human exploration and utilization of space are on the verge of great advances as an international space station is built and becomes operational in the 1990s. Missions to return to the Moon and to venture to Mars will follow in the 21st century and a permanent human presence in space beyond low Earth orbit (LEO) will result. An essential part of these missions is Environmental Control and Life Support (ECLS), in addition to the transfer vehicles, propulsion systems, habitats, and surface roving vehicles that will be required.
Description: Human exploration and utilization of space requires habitats to provide appropriate conditions for working and living. These conditions are provided by environmental control and life support systems (ECLSS) that ensure appropriate atmosphere composition, pressure, and temperature; manage and distribute water; process waste matter; provide fire detection and suppression; and perform other functions as necessary. The functions that are performed by ECLSS are described and basic information necessary to design an ECLSS is provided. Technical and programmatic aspects of designing and developing ECLSS for space habitats are described including descriptions of technologies, analysis methods, test requirements, program organization, documentation requiremens, and the requirements imposed by medical, mission, safety, and system needs. The design and development process is described from initial trade studies through system-level analyses to support operation. ECLSS needs for future space habitats are also described. Extensive listings of references and related works provide sources for more detailed information on each aspect of ECLSS design and development.
