description The Universal Waste Management System (UWMS), which has the ISS operational nomenclature “Toilet”, was initially installed on the International Space Station (ISS) in 2020 with final installation completed in 2021. Technical progress continued to be made with each on-orbit operation that culminated in additional crew use of the UWMS on ISS. Additional problems were evaluated during troubleshooting and testing with the UWMS hardware using water and pretreat to simulate crew use. This paper summarizes the additional testing, troubleshooting and the results as well as characterizes the additional data obtained and summarizes the interpretation of the data to characterize the hardware’s operational nuances. Use of the hardware by crew is planned and will also be summarized. The paper will also describe the additional portions of the technology demonstration that were completed and the benefits that inform the Orion-installed UWMS unit and future manifesting of consumables for both Orion and ISS.
