The recovery of potable water from waste water produced by humans in regenerative life support systems is essential for success of long-duration space missions. The Lunar-Mars Life Support Test Project (LMLSTP) Phase II test was performed to validate candidate technologies to support these missions. The test was conducted in the Crew and Thermal Systems Division (CTSD) Life Support Systems Integration Facility (LSSIF) at Johnson Space Center (JSC). Discussed in this paper are the water recovery system (WRS) results of this test. A crew of 4-persons participated in the test and lived in the LSSIF chamber for a duration of 30-days from June 12 to July 12, 1996. The crew had accommodations for personal hygiene, the air was regenerated for reuse, and the waste water was processed to potable and hygiene quality for reuse by the crew during this period. The waste water consisted of shower, laundry, handwash, urine and humidity condensate.

AiResearch has demonstrated a high-speed axial fan that can be used for space extravehicular activity (EVA) suit ventilation. The fan provides variable flow for the suit in a lightweight, compact design. It combines fine-scale aerodynamics with air bearings and a two-pole toothless permanent magnet motor. The fan has demonstrated quiet, vibration-free operation satisfying performance requirements in a small package: 0.31 l (18.9 cu in.) in volume, 7.8 cm (7 in.) in length, with a weight under 0.9 kg (1.98 lb). This paper describes the fan and control design and discusses test results. The fan accommodates desired changes in the ventilation flow rate by allowing the astronaut to vary fan speed, achieving over a two-to-one range in flow rate. The development program tested the fan at flow rates ranging from 99 to 225 l/min (3.5 to 8 acfm) at operating pressures from 0.414 to 1.586 bar (6.0 to 23 psia) with pressure rises of 0.5 to 2.49 kPa (2.0 to 10 in. H2O).
