ECLSS Trace Contaminant Control Testing

Vast is focused on designing and launching next-generation commercial space stations in Low Earth Orbit (LEO) with induced artificial gravity. A key aspect of any long-duration space station is maintaining a safe, healthy cabin environment. Among the functions toward this end is the trace contaminant control (TCC) system, which ensures that levels of gaseous compounds emitted by human metabolism, hardware offgassing, and vehicle systems operations remain within safe limits. This paper details the testing of a commercial TCC system that was executed using in-house Vast capabilities in partnership with both commercial vendors and the NASA Marshall Space Flight Center’s (MSFC) Environmental Control and Life Support Systems Development Branch. Subscale chemical challenge performance testing was completed onsite at Vast and system-level multi-component challenge testing was completed at MSFC. Results demonstrate that the Vast TCC system is able to maintain a safe and healthy atmosphere for the Haven-1 mission for the designed loads.
