The Four Bed Carbon Dioxide Scrubber (FBCO2) flight demonstration is presently operating as a primary CO2 removal system onboard the International Space Station (ISS). After activation in October 2021, FBCO2 has been removing metabolic CO2 from the ISS cabin where it is supplementing or fully replacing the heritage systems. This paper describes the past year's accomplishments and forward outlook. The performance of the new blower, efforts toward closed-loop operation, and further on-orbit modifications will also be detailed. System reliability, software changes, and ongoing efforts will be summarized.
