“…Several ground-based bioregenerative Life-Support-System studies have been conducted since the 1970s, all including electric or hybrid (electric + solar) lighting (Gitelson et al, 1989;Masuda et al, 2005;Nitta, 2005;Tako et al, 2010;Lasseur et al, 2010). Experiments using the Minitron II growth-chamber/cuvette system to determine maximum growth response for hydroponic lettuce using red-rich incandescent lighting had an associated power cost per unit growth area ranging from 1 to 10 kW/m 2 (power density, where the area term refers to crop-growth area) and an energy consumption per unit dry biomass produced between 953 and 1680 kWh/g (Knight and Mitchell, 1988).…”

“…In our opinion, incorporation of human wastes into the mass exchange inside the system is of primary importance because these wastes can release methane, ammonia, and other gases and, thus, require more complicated pre-storage treatment than plant residues. The efforts to develop technologies for the human wastes' processing for their further application for the plants' nutrition in BLSS were executed previously (Kanazawa et al, 2008;Nelson et al, 2008;Nitta, 2005;Hogan and Finstein, 1991). We are considering the method of human wastes recycling suggested in the given work as a possible alternative to biological oxidation when high rates of wastes processing are required for their further inclusion into the intersystem matter turnover.…”

“…Several research teams conducted experiments in cultivating plants in a closed controlled environment on Earth for the application in future space missions in the past (Wheeler, 2017). Notable are NASA's Biomass Production Chamber (Wheeler et al, 2003;Dreschel et al, 2018), the Russian BIOS facilities (Gitelson et al, 2003), the Japanese Closed Ecology Experimental Facility (Nitta, 2005) and the Chinese Lunar Palace 1 (Fu et al, 2016).…”

Biomass Production of the EDEN ISS Space Greenhouse in Antarctica During the 2018 Experiment Phase

The EDEN ISS greenhouse is a space-analog test facility near the German Neumayer III station in Antarctica. The facility is part of the project of the same name and was designed and built starting from March 2015 and eventually deployed in Antarctica in January 2018. The nominal operation of the greenhouse started on February 7th and continued until the 20th of November. The purpose of the facility is to enable multidisciplinary research on topics related to future plant cultivation on human space exploration missions. Research on food quality and safety, plant health monitoring, microbiology, system validation, human factors and horticultural sciences was conducted. Part of the latter is the determination of the biomass production of the different crops. The data on this topic is presented in this paper. During the first season 26 different crops were grown on the 12.5 m 2 cultivation area of the greenhouse. A large number of crops were grown continuously throughout the 9 months of operation, but there were also crops that were only grown a few times for test purposes. The focus of this season was on growing lettuce, leafy greens and fresh vegetables. In total more than 268 kg of edible biomass was produced by the EDEN ISS greenhouse facility in 2018. Most of the harvest was cucumbers (67 kg), lettuces (56 kg), leafy greens (49 kg), and tomatoes (50 kg) complemented with smaller amounts of herbs (12 kg), radish (8 kg), and kohlrabi (19 kg). The environmental set points for the crops were 330-600 µmol/(m 2 * s) LED light, 21 • C, ∼65% relative humidity, 1000 ppm and the photoperiod was 17 h per day. The overall yearly productivity of the EDEN ISS greenhouse in 2018 was 27.4 kg/m 2 , which is equal to 0.075 kg/(m 2 * d). This paper shows in detail the data on edible and inedible biomass production of each crop grown in the EDEN ISS greenhouse in Antarctica during the 2018 season.
