    • Exploration PLSS Thermal Desktop Modeling 

      Bruce Barnes; Brittany Abraham; Bruno Miranda; Latham Speasmaker; Quoc Nguyen (49th International Conference on Environmental Systems, 2019-07-07)
      The Exploration Portable Life Support System (xPLSS) maintains life support for a suited crew member during Extravehicular Activity (EVA). The thermal and pneumatic/hydraulic interactions within the xPLSS have been modeled ...
    • Methodology for Extravehicular Activity (EVA) Technology Identification, Prioritization, and Maturation 

      Blanco, Raul; Aitchison, Lindsay (48th International Conference on Environmental Systems, 2018-07-08)
      As human exploration of space expands past low earth orbit and into cislunar space and beyond, NASA’s next generation Extra-Vehicular Activity (EVA) system will need technologies exceeding the performance of today’s ...
    • Oxygen Compatibility and Challenge Testing of the Portable Life Support System Variable Oxygen Regulator for the Advanced Extravehicular Mobility Unit 

      Colin Campbell; Marlon Cox; Eric Falconi; Carly Meginnis; Bruce Barnes; Bruce Conger (47th International Conference on Environmental Systems, 2017-07-16)
      The Variable Oxygen Regulator (VOR), a stepper-actuated two-stage mechanical regulator, is being developed for the purpose of serving as the Primary Oxygen Regulator (POR) and Secondary Oxygen Regulator (SOR) within the ...
    • Performance of the Z-2 Space Suit in a Simulated Microgravity Environment 

      Meginnis, Ian; Davis, Kristine; Rhodes, Richard (48th International Conference on Environmental Systems, 2018-07-08)
      The Z-2 space suit is the product of the last fifty years of NASA’s space suit research and testing experience. The suit was originally built as a prototype exploration space suit to evaluate advances in suit design and ...
    • Rapid Cycle Amine Testing History 

      Rachel Sturtz; Bruce Conger; Cinda Chullen (49th International Conference on Environmental Systems, 2019-07-07)
      NASA is developing an Exploration Extravehicular Mobility Unit (xEMU) targeted as a flight demonstration unit on the International Space Station (ISS) in 2023. A major subsystem of the xEMU is the portable life support ...
    • Robust Liquid Volume Sensor for Flexible Bladders in Microgravity 

      Marc Ramsey; Cinda Chullen; Eric Desjardins; David Callender; Jed Wilbur; Nicolas Espinosa; Jay Buckey (49th International Conference on Environmental Systems, 2019-07-07)
      The Portable Life Support System (PLSS) on the Advanced Space Suit (AEMU) will carry consumable cooling water maintained at ambient pressure within an array of soft-walled, flexible reservoirs known collectively as the ...
    • Testing of the NASA Exploration Extravehicular Mobility Unit Demonstration (xEMU Demo) Architecture at the Neutral Buoyancy Laboratory 

      Kristine Davis; Ian Meginnis (49th International Conference on Environmental Systems, 2019-07-07)
      Following Z-2 space suit testing that occurred from 2016-2017, the Exploration Extravehicular Mobility Unit (xEMU) Project was tasked with building a demonstration unit of the xEMU space suit to test on the International ...
