The Trash Compaction Processing System (TCPS) Technology Demonstration and Risk Reduction Updates FY23-FY24


The Next STEP Phase B Trash Compaction Processing System (TCPS) is being developed for a technology demonstration on the International Space Station (ISS) to process common consumables spacecraft trash such as clothing and food packing to reduce the volume, recover the water, safen, and shaped the trash for storage, jettison, reuse (e.g. radiation shielding) and recycling. Sierra Space is developing the flight demonstration hardware and National Aeronautics and Space Administration (NASA) continues to conduct risk reduction activities to vet operational scenarios ensure successful on-orbit tests. After the flight demonstration on ISS, the TCPS can be infused into NASA short- and long-term missions. This paper will discuss the rational for the updated requirement definitions outlined in the 2023 International Conference on Environmental System TCPS paper and the risk reduction activities. In addition, drawing from lesson learned in the development of the TCPS, a discussion of other compression technologies will be introduced.
