Moon Base Life Support Design Depends on Launch Cost, Crew Size, and Mission DurationBrief human space missions such as Apollo and the Space Shuttle used material storage for life support but a long mission such as a space station uses a recycling life support system. The upcoming Moon visits will probably be brief with few crew at first but in the future there may be a long-term or even permanent Moon base with a large crew. The initial life support system will probably use storage and resupply of materials from Earth, but it could be replaced later by recycling, especially if launch cost per kilogram is high. Moon base life support design is investigated considering requirements, performance, reliability, cost, and risk. The launch cost, crew size, and mission duration are variable parameters that affect the life support design choice. Greater launch cost, crew size, or mission duration all tend to make recycling more cost-effective than resupply.
