CHOOSING PLANTS TO BE GROWN IN A CONTROLLED ENVIRONMENT LIFE SUPPORT SYSTEM (CELSS) BASED UPON ATTRACTIVE VEGETARIAN DIETS
Space explorers on the Moon, Mars, or even in a space craft might grow plants in a CELSS to remove C02 and provide 02 and food. Selection of crops to be studied has been rather arbitrary but should be based on plants that can provide a balanced and attractive, mostly vegetarian diet. Additional selection criteria include ease of growth in artificial environments and sufficient variety provided over long intervals. This article is based on a workshop convened to study vegetarian diets for use in a CELSS. Participants included nutritional scientists, practicing vegetarians, and interested employees of the Johnson Space Center. It was concluded that diets meeting the criteria could be formulated, and a list of suitable crops was compiled.
