Book Description
NASA's Controlled Ecological Life Support System (CELSS) Program is involved in developing a bioregenerative life support system that will supply food, air, and water to space crews on long-duration missions. An important part of this effort is development of the knowledge and technological capability of producing and processing foods to provide optimal diets for space crews. This involves such interrelated factors as determination of the diet, based on knowledge of nutrient needs of humans and adjustments in those needs that may be required as a result of the unique conditions of long-duration spaceflight; determination of the optimal mixture of crops required to provide nutrients at levels that are sufficient but not excessive or toxic; and consideration of the critical issues of spacecraft space and power limitations, which impose a phytomass minimization requirement. This publication examines the complex interactions among these factors, with the goal of supplying a diet that will satisfy human needs while minimizing the total phytomass requirement. The approach taken has been to collect plant nutritional composition and phytomass production data, identify human nutritional needs and estimate the adjustments to the nutrient requirements likely to result from spaceflight, and then to generate mathematical models from these data.
