tl;dr University of Arizona has restored a test greenhouse as the centerpiece for closed ecosystem research [0]. They plan to connect several other closed units to serve as housing and labs. The 'simulation' involves stepping down the use of CO2 scrubbers as they grow more and more plants to convert the atmosphere, with special attention to the entire lifecycle (ex decomposition releases lots of CO2, so they are apt to turn on scrubbers unused during the maturation phase). The program is currently 1/3 funded. [0] https://samb2.space/about/ https://samb2.space/about/
