Preliminary Results of NASA ECLSS Life Testing

As part of the development of the Environmental Control and Life Support System (ECLSS) for the International Space Station (ISS), the National Aeronautics and Space Administration (NASA) has been conducting extended duration testing of ISS critical ECLSS subassemblies. The ECLSS Life Testing Program (ELTP), which is being conducted in the Core Module Integration Facility (CMIF) at Marshall Space Flight Center (MSFC), began in November 1992. Since that time subassemblies for trace contaminant control, carbon dioxide removal, and urine processing have been operated continuously under simulated ISS loads. The performance of each subassembly and details concerning subassembly test anomalies are provided.
