Integrated System Design for Air Revitalization in Next Generation Crewed Spacecraft

Human space initiatives that involve long-duration space voyages and interplanetary missions are possible only with the technologies that enable integration of the air, water, and solid waste treatment systems that minimizes the loss of consumables. However, the capabilities of NASA's existing environmental control and life support (ECLS) system designs consist of many independent systems that are energy extensive. This paper discusses the concept of an integrated system of CO₂ removal and trace contaminant control units that utilizes novel gas separation and purification techniques and optimized thermal and mechanical design for future spacecraft. The integration process will enhance the overall life and economics of the existing systems by eliminating multiple mechanical devices with moving parts.
