Performance of the Water Recovery System During Phase II of the Lunar-Mars Life Support Test Project

Four-month Moon and Mars crew water utilization study conducted at the Flashline Mars Arctic Research Station, Devon Island, Nunavut

“…Other recent references do suggest differing values and these are presented in the additional columns of Table 17 which compares FMARS2007 study results to current literature for nominal 24-h days. Verostko et al (1997) presents water balance data from the four crewmember LMLSTP Phase II, 30 day integrated test conducted in 1996. The LMLSTP was able to capture categorized water use data in the majority of categories by incorporating a water outlet for each of the various water use categories (e.g.…”

“…tion on the purpose of the water use (Philistine, 2003). 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). The deployment of a suite of flow meters allowed for categorized water use measurements to be taken during the FMARS2007 expedition.…”

“…As very few regenerative life support systems have yet been implemented operationally on-orbit for water, better confidence/bounds on crew water use for long duration missions are even more critical, considering only moderate levels of closure may exist for early missions to the Moon and Mars. Past spaceflight experience and ground based studies can provide results useful for future water use estimates (Colombo et al, 1971;NASA, 1970;Verostko et al, 1997;Philistine, 2005;Osburg, 2007). The value of results increases when conducting a monitoring program under operationally relevant mission constraints and in an operationally relevant environment.…”
