jsc2023e010167 (1/30/2023) --- CapiSorb Visible System flight unit degasser assembly in N240 room 133B. The CapiSorb Visible System will be launched on SpaceX CRS-27 in March 2023 to the International Space Station to demonstrate a liquid sorbent-based system that leverages the advantages of liquid control through capillary action to remove carbon dioxide from crewed atmospheres...Capillary wedges in the CapiSorb Visible System Degasser, shown here pre-flight, control and passively transport viscous liquid in microgravity in order to demonstrate capabilities needed for future liquid sorbent carbon dioxide removal technologies. The CapiSorb Visible System investigation demonstrates a liquid control using capillary forces, over a range of liquid properties that are characteristic of liquid carbon dioxide sorbents.
