Integration test project of CEEF — A test bed for closed ecological life support systems

Human habitats: prospects for infrastructure supporting astronomy from the Moon

“…Other habitats have been used as facilities to test life support systems with humans in the loop, such as the Japanese Closed Ecology Experiment Facilities (CEEF, [108]) or the Soviet Bios-3 facility [109]. A more recent example for a life support system testing facility is the Chinese Lunar Palace 1 which has been in use since 2014 [110].…”

Agriculture for Space: People and Places Paving the Way

“…At about the same time as planning for NASA's BIO-Plex facility was taking place, Japanese researchers working with Dr. Keiji Nitta began development of the Closed Ecological Experiment Facility (CEEF) in Aomori Prefecture (Ashida and Nitta, 1995;Nitta et al, 2000) (Fig. 5).…”

“…CEEF was part of the Institute for Environmental Sciences (IES) developed to track radio isotopes through closed ecosystems. When not in use for their primary studies, the facilities could be utilized for studies of controlled environment agriculture and human life support (Nitta et al, 2000;Tako et al, 2001Tako et al, , 2008Tako, 2010). CEEF researchers designed complete diets from crops grown in 150 m 2 of the plant cultivation modules (Masuda et al, 2005;Tako et al, 2010.).…”

Effects of long-term closed and socially isolating spaceflight analog environment on default mode network connectivity as indicated by fMRI

“…It has a significant material closure and circulation 3 and can provide enough breathable air, clean water, essential food, and safe working-living places for human beings (crewmembers). Various closed ecological system experiments have been conducted to date, including Biosphere 2 project, 4 , 5 the BIOS-3, 6 the Closed Ecological Experimental Facility, 7 and the 2-person-30-day CELSS in Beijing. 8 However, challenges still persist, one of which is the potential influence of closed spaceflight environment on the brain functioning of the crewmembers.…”
