Human life support systems for long-duration manned space missions need to be robust, reliable, self-sustaining, and efficient in terms of mass, power, and volume. The National Aeronautics and Space Administration (NASA) administers the Advanced Life Support (ALS) program, in which biological systems are combined with physical and chemical technologies to accomplish these goals. Hydroponic, controlled environment production of higher plants, such as salad crops, as well as wheat, rice, white potato, and soybean, is expected to help satisfy requirements for crew nutrition, atmospheric oxygen and carbon dioxide recycling, potable water production, and waste treatment and resource recovery. Successful ALS systems require the development and application of information and decision support tools, growth monitoring techniques, and sophisticated analysis methods, some of which will be described in this section.
