Bioregenerative life-support (BLSS) studies were completed at the University of Arizona Controlled Environment Agriculture Center (UA-CEAC) with support by the Arizona NASA Ralph Steckler Phase II Space Grant. In cooperation with Sadler Machine Co. (USA) and international Italian collaborators, Thales Alenia Space Italia (TAS-I) and Aero-Sekur, SpA, and AGC Green-Tech Co. (Japan), a lightweight flexible cable culture hydroponic plant production system incorporated with an automated 23 m3, sealed, collapsible plant growth chamber was used to demonstrate polyculture production of food crops and air revitalization in a semi-closed Lunar Greenhouse Prototype (LGH). Mass and energy balances were measured and the flows of input resources (i.e. water, carbon dioxide, dry fertilizer salts, labor, electricity and heat) and output production (i.e. food, water condensate, oxygen and heat) were quantified for the purpose of demonstrating life support capability utilizing biological processes under controlled environments for human space applications.
