Whither the Life-Support System?
1980The human population of the globe has been increasing according to some superexponential law. One possible form of this relationship is: where N is the total population size, and t the time in years AD. This expression was derived by fitting a model, which assumes the rate of increase to be a weak monotonic increasing function of N, to 24 estimates of ...

Fundamentals of Life Support Systems
1996Thermodynamically speaking, man as a living creature is an open system, i.e., he exchanges matter and energy with his environment that maintains its own structure. He is living in his closed terrestrial life support system known as the “biosphere”. The biosphere is a basically closed system in terms of matter, but an open one in terms of energy.

Life support system development in West Germany
Acta Astronautica, 1982The delivery of fully qualified Environmental Control and Life Support System (ECLS) flight hardware for the Spacelab Flight Unit was completed in 1979, and the first Spacelab flight is scheduled for mid 1983. With Spacelab approaching its operational stage, ESA has initiated the Follow-on Development Programme.

Biological life-support systems for Mars mission
Advances in Space Research, 1992Mars mission like the Lunar base is the first venture to maintain human life beyond earth biosphere. So far, all manned space missions including the longest ones used stocked reserves and can not be considered egress from biosphere. Conventional path proposed by technology for Martian mission LSS is to use physical-chemical approaches proved by the ...

Biogenerative life-support system: Farming on the Moon
Acta Astronautica, 1991Plants can be used to recycle food, oxygen, and water in a closed habitat (e.g., on the moon, Mars, or in a space craft. A variety of crops might be grown, probably in underground growth units to avoid harmful radiation and micrometeorites. Artificial light will be necessary although some sunlight might be brought in via fiber optics.
