Аннотация: To create a life support system based on biological and physical-chemical processes is the optimum solution providing full-valued condidtions for existence and efficient work of people at a lunar base. Long-standing experinece in experimental research or closed ecosystems and their components allows us to suggest a realistic functional structure of the lunar base and to estimate qualitatively its parameters. The original restrictions are as follows: 1) the basic source of energy to support the biological processes has to be the solar radiation; 2) the initial amount of basic biological elelments forming the turnover of substances (C, O, H, P, K, N) has to be delivered from Earth; 3). Moon materials are not to be used in the biological turnover inside the base; 4) the base is to supply the crew fully with atmosphere and water, and with 90% (A scenario) or 40% (B scenario) of food. Experimental data about the plant productivity under the "Moon" rhythm of light and darkness allow us to suggest that the A scenario requires per one human: plant area - 40 m2 irradiated during the lunar day by 250-300 W/m2 PAR producing 1250 g of dry biomass a terrestrial day; a heterotrophic component of "biological incineration" of inedible plant biomass (800 g/day) including the aquaculture of fish to produce animal products and contaminating the environment less than birds and mammals, and the culture of edible mushrooms; a component of physical-chemical correction for the LSS envi ronment including the subsystems of: deep oxidation of organic impurities in the atmosphere and of water, organic wastes of human activity and that biological components (420 g/day) Co2 concentration in "Moon" nights, damping O2 in "Moon" days, etc. The stock of presotred or delivered from Earth substances (food additions, seeds, etc.) to be involved in biological turnover is to be about 50 kg/year per man. Increase of the mass of prestored substances per man up to 220 kg/year would reduce twice the plant area and consumed amount of radiant energy to exclude the components of "biological incineration" and physical-chemical destruction of organic wastes.

Аннотация: In the paper an attempt is made to combine three important criteria of LSS comparison: minimum mass, maximum safety and maximum quality of life. Well-known types of BLSS were considered: with higher plant, higher plants and mushrooms, microalgae, and hydrogen-oxidizing bacteria. These BLSSs were compared in terms of "integrated" mass for the case of a vegetarian diet and a "normal" one (with animal proteins and fats). It was shown that the BLSS with higher plants and incineration of wastes becomes the best when the exploitation period is more than 1 yr. The dependence of higher plants' LSS structure on operation time was found. Comparison of BLSSs in terms of integral reliability (this criterion includes mass and quality of life criteria) for a lunar base scenario showed that BLSSs with higher plants are advantageous in reliability and comfort. This comparison was made for achieved level of technology of closing and for perspective one. В© 1997 Elsevier Science Ltd.

Заглавие : Opportunities and constraints of closed man-made ecological systems on the moon
Место публикации : Advances in Space Research. - 1994. - Vol. 14, Is. 6. - С. 271-280. - ISSN 02731177 (ISSN)
Аннотация: Most scenarios for a manned lunar base include a combination of physical-chemical and bioregenerative life support systems. Especially on the lunar surface, however, there is a series of special environmental factors which seriously affect the organisms suitable for food production and biological regeneration of the habitat atmosphere and water. So, e.g. the lunar day/night period creates difficult problems for higher plant culture. The paper presents the current scientific approaches to bioregenerative life support systems of a lunar base and discusses critically the possibilities of their realization. Moreover, a scientific strategy is developed with the biologist's point of view to implement in a stepwise manner bioregenerative life support modules into a lunar base covering the possibilities of the untilization of chemolytotrophic bacteria, microalgae and higher plants as well as those of animal breeding and protein production in intensive aquaculture systems.
