OPPORTUNITIES AND CONSTRAINTS OF CLOSED MAN-MADE ECOLOGICAL-SYSTEMS ON THE MOON

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.
