“…The urine amount in the current experiment were within the range observed by NASA (1,390-2,107 g person −1 day −1 ) in previous studies 21 , but the feces were slightly more than those measured by NASA (20.5-132.0 g person −1 day −1 ). This may be because the diet of the crew in the current experiment had more abundant fiber and additional fiber in the diet was known to increase daily stool mass 39 .…”

Bioregenerative life support system (BLSS) is a critical technology maintaining long-term human survival on the Moon or other extraterrestrial bodies. In the current study, we carried out a 370-day integrated high-closure experiment (“Lunar Palace 365” experiment) on the Earth in an upgraded ground-based BLSS experimental facility called “Lunar Palace 1”. This experiment was designed to develop techniques to run and adjust system stability under long-term operation and crew shift change conditions. Eight volunteering crew members were divided into two groups with three time phases: Group I stayed in the cabin for the initial 60-day phase; Group II inhabited the cabin instead for a record-breaking duration of 200 days as the second phase; Group I re-entered the cabin, replaced Group II and stayed for the last 105 days. Our results demonstrated the BLSS had excellent stability with a material closure degree of 98.2%. Levels of O2, CO2 and trace harmful gases were well controlled within ranges optimal for crew health and plant production. The system exhibited a strong robustness and could quickly minimize effects of disturbances through self-feedback adjustments. The efficiency of plant production completely met the crew’s need of plant-based food. The purification efficiency of domestic and sanitary wastewater was up to irrigation standards, and the recovery rate of urine and solid waste achieved 99.7% and 67%, respectively. These results are valuable for further optimization of the BLSS in a lunar base and computer simulations of similar systems.

“…Animal protein is another bioregenerative food that may be an important contribution for both nutrition and acceptability over time [18,19], as a vegan-only system would not be acceptable to many astronauts. Although there has been recent progress in animal cell culture, substantial infrastructure efficiencies and culture media sustainability solutions would need to be achieved for spaceflight feasibility [20].…”

“…These are examples where specialists or intensive automation may be required, further increasing the resource requirements. Reports on crop-based food systems to date provide some example menus with initial evaluations of acceptability and comparisons to nutritional requirements, but they do not include processing, preparation, and crew time requirements or acceptability over time [19,40,55], leaving a substantial gap. Processing and preparation infrastructure and integration requirements with flight-ready air and water systems also need to be included in trade comparisons with other systems.…”

Sustaining Astronauts: Resource Limitations, Technology Needs, and Parallels between Spaceflight Food Systems and those on Earth

Food and nutrition are critical to health and performance and therefore the success of human space exploration. However, the shelf-stable food system currently in use on the International Space Station is not sustainable as missions become longer and further from Earth, even with modification for mass and water efficiencies. Here, we provide a potential approach toward sustainability with the phased addition of bioregenerative foods over the course of NASA’s current mission plans. Significant advances in both knowledge and technology are still needed to inform nutrition, acceptability, safety, reliability, and resource and integration trades between bioregenerative and other food systems. Sustainability goals on Earth are driving similar research into bioregenerative solutions with the potential for infusion across spaceflight and Earth research that benefits both.
