Summary:

This paper presents the results of data measurements for a human material balance, which were conducted as part of a 2-day manned test of a regenerative Environmental Control and Life Support System (ECLSS) in an isolation chamber. The manned test was carried out using a man-rated closed chamber operated in airtight mode at the Tsukuba Space Center of NASDA (National Space Development Agency of Japan), Tsukuba, Japan. A five-person Japanese test crew resided inside the isolation chamber for 48 consecutive hours, living and working along a time schedule based upon Space Shuttle and ISS activities. Data measured on human material needs and effluents included drinking water and beverages, food, urine, feces, water vapor (latent respiration and perspiration), and metabolic trace gases, which were measured directly with scales or estimated indirectly in various ways, such as measuring crew weight change, or measuring air temperature and humidity. Based on those data we made a human material balance numerical model and compared the results to similar models that have been developed
