RECOVERY OF POTABLE WATER FROM WASTEWATER IS ESSENTIAL TO THE SUCCESS OF LONG-DURATION HUMAN SPACEFLIGHT. FOR HUMAN MISSIONS TO MARS, THE TECHNOLOGY MATURATION (TA 207) OBJECTIVE IS TO RECOVER GREATER THAN 98 PERCENT OF THE WATER FROM WASTEWATER SOURCES (URINE, HUMIDITY CONDENSATE, ETC.). THIS CONTRACT IS FOR THE DEVELOPMENT OF IONOMER-MEMBRANE WATER PROCESSOR (IWP) BRINE PROCESSOR FOR FLIGHT DEMONSTRATION ON THE INTERNATIONAL SPACE STATION (ISS). REQUIREMENTS FOR THE BRINE PROCESSOR WILL BE BASELINED BY NASA AND AGREED TO BY THE CONTRACTOR UNDER THE PHASE III SBIR NNX16CJ02C. AN ISS FLIGHT DEMONSTRATION IS NEEDED TO VALIDATE AND FULLY CHARACTERIZE BRINE PROCESSOR SYSTEM PERFORMANCE IN A RELEVANT ENVIRONMENT FOR FUTURE EXPLORATION MISSIONS. THE RELEVANT ENVIRONMENT IN THIS CASE INCLUDES BOTH MICRO-GRAVITY AND LONG-DURATION EXPOSURE TO MICRO-G CREW-PRODUCED BRINE VIA THE URINE PROCESSOR. THE BRINE PROCESSOR WILL BE FLOWN AS A CLASS 1E PIECE OF HARDWARE. TASKS INCLUDE 1) COMPLETE TECHNOLOGY MATURATION OF KEY COMPONENT SUBSYSTEMS OF THE IWP FROM THE PHASE III SBIR INCLUDING BLADDER HEAT SEALING, LOW-PROFILE SIDE-MOUNTED FILL PORT, DETRUSOR AND SYSTEM COMPATIBILITY WITH INADVERTENT EXPOSURE TO 14.7 PSIG DURING BRINE FILL; 2) SYSTEM DESIGN CYCLE INCLUDING HEATER AND ENERGY MANAGEMENT TRADE; 3) INTEGRATED SYSTEM AND COMPONENT PRELIMINARY DESIGN; 4) INTEGRATED SYSTEM AND COMPONENT FINAL DESIGN AND REVIEW; 5) MANUFACTURING OF ONE COMPLETE IWP ASSEMBLY, 42 BLADDERS (18 FOR QUALIFICATION TESTING AND 24 FOR FLIGHT), ONE NON-OPERATING TRAINING UNIT WITH SPARES; 6) PROTOFLIGHT QUALIFICATION TESTING AND BLADDER ACCEPTANCE TESTING; 7) HARDWARE ACCEPTANCE REVIEW AND DELIVERY OF A BRINE PROCESSOR AND ASSOCIATED CONSUMABLES, FOR AN ISS TECHNOLOGY DEMONSTRATION; 8) POST-DELIVERY AND ON-ORBIT SUPPORT WHICH INCLUDES GENERATION OF OPERATIONS AND MAINTENANCE HANDBOOK FOR USE BY NASA IN SUPPORT OF CREW TRAINING AND THE DEVELOPMENT OF ON-ORBIT OPERATIONS AND MAINTENANCE, CREW TRAINING SUPPORT, AND ON-ORBIT OPERATIONS SUPPORT AND SUPPORT WITH NASA ON-ORBIT ANOMALY RESOLUTION AND GENERATION OF AN ON-ORBIT TEST REPORT WITH LESSONS LEARNED AND RECOMMENDATIONS FOR IMPROVEMENTS.
