a Sketches of fluid bearing chambers for ISS capillary fluidics experiments CFE and CFE-2 to approximate scale with dimensions in cm: moving Contact Line dynamics and capillary stability (CL), critical geometric wetting in an elliptical cylindrical container with pivoting Vane with Gap between wall and vane (VG), and ullage migration due to Interior Corner Flow (ICF). b Flight images of static interface configurations in VG1 demonstrating critical geometric wetting and dynamic images in c ICF1, d ICF2, and e ICF8 demonstrating ullage migration with passive bubble phase separations.
