Evaluation of a Closed-Cycle Life-Support System During a 60-Day Manned Test 680741

A 60-day manned test of a closed-cycle life-support system was completed in a Space Cabin Simulator. Life-support equipment was installed within the chamber and was operated, maintained, and repaired by a 4-man crew. Major objectives of the test included demonstrations of the recovery of potable water from urine and humidity condensate, and the recovery of oxygen from carbon dioxide. Other life-support equipment included a thermal-control subsystem, a two-gas atmosphere control, a trace-contaminant removal subsystem, and a fecal-waste collector that featured vacuum dehydration.
