The Space Station Freedom (SSF) Environmental Control and Life Support System (ECLSS) Atmosphere Revitalization (AR) subsystem conditions the cabin atmosphere to provide a safe habitable environment for the 4-person astronaut crew. The first phase of the ECLSS development testing, namely the AR POST, focuses on the SSF Man Tended Capability (MTC) configuration. The scheduled 34-day integrated AR POST was conducted by Boeing at Marshall Space Flight Center (MSFC) Building 4755, Huntsville, Alabama and completed March 21, 1992. A test timeline is presented in Figure 1. This test was the first time the three baselined ECLSS Man Tended Capability (MTC) AR assemblies were integrated and operated in a closed door chamber in which the internal atmosphere was monitored. This paper details the initial results of the Integrated AR POST. Future considerations for the Integrated Single String POST are also discussed.
