The Four Bed Carbon Dioxide Scrubber flight demonstration is presently operating onboard the International Space Station. After being launched in August of 2021 and installed in October, the system has been removing metabolic CO2 from the cabin as a supplement and replacement for other CO2 systems, specifically the two Carbon Dioxide Removal Assemblies. This work describes the conclusion of the ground integration and testing campaign and the start of on orbit operations. Additionally, performance, reliability, and forward works will be summarized. Interactions of the software with off-nominal events will be discussed and how the system will be reconfigured to sustain operations.
