nspiration Mars is an endeavor to launch two crew members on a 500 day fast free trajectory flyby of Mars. Preliminary analyses have shown that the required technology to facilitate such a manned voyage primarily already exists. However, before full scale development of the flight system, it must first be determined that the state of the art technologies of today will, in fact, be sufficient to execute such a mission successfully or demonstrate a path to necessary maturity. The Inspiration Mars Environmental Control and Life Support Systems (ECLSS) Technology Demonstration Unit (ETDU) program sought to develop a bench-top level closed ECLSS that is sufficient to demonstrate these key technologies. ETDU has completed testing six key elements which enable closed loop life support. Of those six elements, two are included in the Water Management System (WMS): Primary Water Processor (PWP) and Urine Processor (UP). The PWP was baselined on the International Space Station (ISS) water processor. The UP is based on new urine processing technology being developed by Paragon. Both of the assemblies were developed and tested at the Paragon facilities in Tucson. Test results including processing rates and water quality are presented.


The 44th International Conference on Environmental Systems was held in Tuscon, Arizona, USA on 13 July 2014 through 17 July 2014.
