jsc2023e010168 (1/30/2023) --- CapiSorb Visible System flight unit contactor 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 Contactor, shown here preflight, control and passively transport viscous liquid in microgravity in order to demonstrate capabilities needed for future liquid carbon dioxide removal technologies. The CapiSorb Visible System investigation demonstrates a liquid control using capillary forces, over a range of properties that are characteristic of liquids which absorb carbon dioxide.
