3.1 human habitation environment in spacecraft
complex issue that involves material, energy and information flows, as well as elements formed in SC habitable compartments
Note 1 to entry: Such elements are derived from life activity processes, human social-labour processes, space factors, space mobility, and hardware functioning processes, including the ones designed to arrange humans’ interaction with the habitation environment in order to provide specified conditions for human life activity in
space flights.
[SOURCE: ISO 17763, 3.1]
3.2 human living conditions in SC
complex of human habitation environment parameters in SC, providing health maintenance, human safety and keeping of his ability to work at a level needed to execute the planned work program
[SOURCE: ISO 17763, 3.2]
3.3 techno-medical requirements for human habitation environments
complex of biomedical, hygiene/sanitary, ergonomic and design issues
Note 1 to entry: Those requirements take into account physiological and social-psychological human needs in the process of hardware development and operation in order to guarantee specified living conditions aboard space systems.
[SOURCE: ISO 17763, 3.3]
3.4 manned (habitable) spacecraft
spacecraft, spaceship, space station, Lunar or planetary base with pressurized components inside which human habitation environment is maintained
[SOURCE: ISO 16157, 3.4]
3.5 life support systems
systems supporting mass and energy exchange between space traveller’s body and habitable environment inside MSC
