Engineering concepts for food processing in bioregenerative life support systems.
Long-duration manned missions, such as Mars exploration, will require development of new and cost-effective food production and delivery systems. Requirements for both carry-on preserved food and food processed from on-board crops exceed the capabilities of existing food processing and preservation technologies. For the transit phase, new food products, preservation methods, and processing technologies for ground-based food processing are required. The bioregenerative surface phase requires methods for processing of in situ-grown crops, treatment of food wastes, preparation of daily meals, and design of nutritious and appealing plant-based menus, all within severe cost and labor constraints. In design of the food supply for a long-term mission, the designers must select and apply both the packaged food and in situ processing technologies most appropriate for the specific mission requirements. This study aims to evaluate the strengths and weaknesses of different food system strategies in the context of different types of mission, and to point out the most important areas for future technology development.
