Atmosphere Trace Contaminant Removal for Human Exploration

As the commercial space industry grows, Environmental Control and Life Support Systems (ECLSS) are required to perform with more efficiency, using less power, holding less mass, and enveloping less volume. This is accomplished by implementing innovative designs and solutions while maintaining or increasing each system�s effectivity. A system to remove atmospheric trace contaminants will be required for many human spaceflight programs in the future including space stations in Low Earth Orbit (LEO), Lunar surface habitats, Mars transit vehicles, and Martian surface habitats. This paper will explore design and operational choices which, when implemented, will produce a system to control gaseous trace contaminants that fulfills the needs of future human spaceflight programs.
