Designing the most effective and efficient life support systems is of extreme importance as the United States makes plans to return astronauts to the Moon. The Trace Contaminant Control System (TCCS), which will be located within the Portable Life Support System (PLSS) of the Constellation spacesuit element (CSSE), is responsible for removing contaminants that, at increased levels, can be hazardous to crew member health. These contaminants arise from several sources including metabolic production of the crew member (e.g., breathing, sweating, etc.) and offgassing of the spacesuit material layers. This paper summarizes the results of a trade study that investigated TCC technologies that were used in NASA space-suits and vehicles, as well as commercial and academic applications, to identify the best technology options for the CSSE PLSS. The trade study also looked at the feasibility of regeneration of TCC technologies, specifically to determine the viability of vacuum regeneration for on-back, real-time extravehicular activity.
