The most inclusive categorized water use results as of late are those collected during the Lunar-Mars Life Support Test Project (LMLSTP) (Verostko et al, 1997).…”

“…Very little work in recent years has been conducted to validate these design parameters using new, potentially more operationally relevant environments for Moon/Mars surface stays. Now operational, the ISS is one potential venue for such a study, but it hosts no sensors for water use tracking, apart from condensate monitoring (Philistine, 2003). Actual ISS usage rates are estimated based on the number of potable and technical contingency water containers used over given periods, but provide little informa- Fig.…”
