| Abstract: | A compilation of generation rates and chemical compositions of potential waste streams in a typical crewed space habitat, reported in a prior NASA Technical Memorandum and a related journal article, has been updated. This paper augments that compilation by the inclusion of the following new data: those uncovered since completion of the prior report; those obtained from Soviet literature relevant to life support issues; and those for various minor human body wastes not presented previously (saliva, flatus, hair, finger- and toenails, dried skin and skin secretions, tears and semen), but included here for purposes of completeness. These waste streams complement those discussed previously: toilet waste (urine, feces, etc.), hygiene water (laundry, shower/handwash, dishwash water and cleansing agents), trash, humidity condensate, perspiration and respiration water, trace contaminants and dust generation. This paper also reproduces the latest information on the environmental control and life support system design parameters for Space Station Freedom. |
