ENVIRONMENTAL REQUIREMENTS OF SEALED CABINS FOR SPACE AND ORBITAL FLIGHTS. SPACE AGE UTILIZATION OF RECYCLED METABOLIC WASTES

Abstract

The analysis of daily urine samples from a test subject revealed normal values in regard to specific gravity and pH. The former determination varied between 1.011 and 1.023; the latter, between 5.0 and 6.0. Qualitative albumin and sugar determinations were negative. Urine color varied from light yellow and clear early in the test period to yellow and cloudy on the last day. Analysis on samples of recovered water revealed excessive acidity on the first three days of the test. The level of pH was maint ined at near neutral levels for the remainder of the test. Recycled urine showed no traces of epinephrine and norepinephrine. Daily water intake was maintained, the palatability and odor-free characteristics of the potable water being totally acceptable. The test subject (RAB) suffered no ill effects and the device appears to have good potential for space flight applications. (Author)
