The Four Bed Carbon Dioxide Scrubber flight demonstration is presently operating onboard the International Space Station. After being launched in August and activated in September 2021, the system has been removing metabolic CO2 from the cabin as a supplement and replacement for other CO2 removal systems, specifically the two Carbon Dioxide Removal Assemblies. This paper describes on-orbit operations and changes (including installation of the Calnetix blower) during 2022 and early 2023. Performance of the system especially as affected by changes in the on-orbit configuration will be described. System reliability, software changes, and ongoing efforts will be summarized.
