Shortfalls in our understanding of capillary phenomena are amplified in reduced-gravity environments of space where their impacts occur over truly macroscale length scales many orders of magnitude larger than on earth. Based on practical experience, it can be argued that nearly all fluid systems aboard spacecraft are or become multi-phase capillary fluid systems. This fact has been known to NASA and the aerospace community for many decades, which is why the topic remains the highest priority within the Fluid Physics subcategory of the Physical Sciences. It is both ‘enabling’ and ‘enabled by.’
