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

“…These require extensive processing, preparation, system experts with dedicated time, and infrastructure that would introduce vehicle integration challenges. Most studies that present these foods as spaceflight solutions do not discuss these challenges [13,14], do not acknowledge the history of work in the area in relation to spaceflight, and do not provide solutions to overcome the poor acceptability of many of these products to date [15][16][17], leaving a substantial gap.…”

“…A lot of work has been done with bioregenerative food systems over the past 60 years. We would encourage anyone working in these areas to investigate this past research, which exists for many concepts [16,17,35]. We are focusing on crops as an example of a roadmap to integration with the space food system for several reasons.…”

Microalgae Wastewater Treatment: A Brief History

“…Implementation of this microalgae waste treatment system in the US took the form of a semi-continuous photobioreactor dubbed the 'Algatron' (Aronowsky, 2017;Munns & Nickelsen, 2017;Shelef et al, 1970). Early tests of this system with mice showed that it was successful in acting as a photosynthetic gas exchanger over a long duration (Krauss, 1966;Myers, 1960).…”
