Cost-effective high reliability can be achieved in future space life support systems through careful systems analysis and design. This paper outlines a comprehensive approach. Potential future human space missions are described. The mission parameter impacts on life support system design and reliability requirements are discussed. Not all human space missions require high reliability life support. The potential reliability and cost of storage and of recycling life support systems are investigated. Simple storage systems can provide cost-effective high reliability life support where it is needed. More complex recycling systems with lower reliability and higher cost can be used when suitable.
