“…photosynthetic algae or bacteria) for nutrient removal. At least one genus of algae, Chlorella, is being investigated as an easily cultivable food supplement [ [228] , [229] , [230] ]. This could have additional positive results, such as CO 2 removal, O 2 production, and generation of edible biomass.…”

“…Beside the on-demand crew consumption, on-board waters are distributed for different purposes, comprising hygiene and cleaning practices, urinal flushing, oxygen generation via electrolysis, life-support systems, and flexible water-based experimental activities (e.g., vegetable and food production systems, animal physiology and behavioral adaptation tests) (Baiocco et al, 2018;Chatani et al, 2015;Massa et al, 2016;Niederwieser et al, 2018;Ronca et al, 2019;Wolff et al, 2018). Wastewaters are continuously collected and recycled at high efficiency level.…”

Space exploration is demanding longer lasting human missions and water resupply from Earth will become increasingly unrealistic. In a near future, the spacecraft water monitoring systems will require technological advances to promptly identify and counteract contingent events of waterborne microbial contamination, posing health risks to astronauts with lowered immune responsiveness. The search for bio-analytical approaches, alternative to those applied on Earth by cultivation-dependent methods, is pushed by the compelling need to limit waste disposal and avoid microbial regrowth from analytical carryovers. Prospective technologies will be selected only if first validated in a flight-like environment, by following basic principles, advantages, and limitations beyond their current applications on Earth. Starting from the water monitoring activities applied on the International Space Station, we provide a critical overview of the nucleic acid amplification-based approaches (i.e., loop-mediated isothermal amplification, quantitative PCR, and high-throughput sequencing) and early-warning methods for total microbial load assessments (i.e., ATP-metry, flow cytometry), already used at a high readiness level aboard crewed space vehicles. Our findings suggest that the forthcoming space applications of mature technologies will be necessarily bounded by a compromise between analytical performances (e.g., speed to results, identification depth, reproducibility, multiparametricity) and detrimental technical requirements (e.g., reagent usage, waste production, operator skills, crew time). As space exploration progresses toward extended missions to Moon and Mars, miniaturized systems that also minimize crew involvement in their end-to-end operation are likely applicable on the long-term and suitable for the in-flight water and microbiological research.

“…More recently, microalgae, another photosynthetic organism, have been cultivated in BLSS research (Niederwieser et al 2018a). The green algae Chlorella vulgaris in particular seems to be a promising candidate for an aquatic food loop (Niederwieser et al 2018b). However, food sources based solely on the fruits and vegetables that have been studied for space systems do not cover all human dietary requirements (Lane et al 2013).…”

Food autonomy represents an essential challenge for the future Moon Village planned by the European Space Agency. Rearing fish on the moon to provide essential amino acids, omega-3 polyunsaturated fatty acids and vitamin B 12 could become a reality using integrated multi-trophic aquaculture (IMTA). The Lunar Hatch programme's goal is to fertilize farmed fish eggs on Earth that would hatch upon arrival at the lunar base. However, the vibrations from a spacecraft's launch are an unusual situation for fish eggs and may have a negative impact on them. European sea bass (Dicentrarchus labrax) and meagre (Argyrosomus regius) eggs were exposed to mechanical stresses using standard protocol performed to approve a satellite for space launch. The hatching rate was evaluated after vibration expositions at different hours post fertilization (hpf). An initial series of tests subjecting the eggs to orbital rotation demonstrated their integrity. In subsequent tests, mechanical stressors acting on the Soyuz spacecraft was simulated to test impact on fish eggs. The results showed egg robustness for European sea bass at 35 hpf (one-third of the embryo development) and 83 hpf (two thirds) and of meagre at 14 hpf (one third), with no significant difference in hatching rate compared with an unshaken control batch. European sea bass embryos and potentially other fish species with similar incubation periods (4-6 days) seem to be good candidates to surviving a spacecraft launch. This paper discusses the findings and suggests possible future research avenues.
