| Description: | Long-duration space missions require the development of advanced life support systems. The study of the Earth’s biosphere, the biotic and abiotic components that dominate the environment would be beneficial in the search for the development of an artificial ecosystem in space. Matter and energy on Earth are constantly flowing. The composition of the atmosphere and microorganisms play an important role in the circulation of all resources on Earth. On the other hand, there are artificial ecosystems designed to support life during space missions. There are two types of systems approaches, open and closed loop. In addition, there are two kinds of technological approaches to an LSS. The physicochemical and the bioregenerative. The former cannot produce food and the latter is more complex and has low TRL. A solution that compensates for both is a hybrid LSS that combines both technologies. The nutritional requirements of humans cannot be met by eating only plants for long periods of time. An aquaculture system within a hybrid LSS would create a self-sufficient ecosystem consisting of microorganisms, terrestrial and aquatic plants and aquatic animals. Furthermore, this project investigates the role of beneficial bacteria within a LSS. Finally, a new hybrid LSS is proposed based on the case studies of the Precursor Food Production Unit, the Closed Loop Food Systems study, the Micro-Ecological Life Support Alternative Systems - MELiSSA and the Closed Equilibrated Biological Aquatic System (C.E.B.A.S.). |
