U.S. Spacesuit Knowledge Capture Accomplishments in Fiscal Years 2012 and 2013

Chullen, Cinda; Oliva, Vladenka R. (44th International Conference on Environmental Systems, 2014-07-13)

The NASA U.S. Spacesuit Knowledge Capture (KC) program has existed since the beginning of 2008. The program was designed to share historical spacesuit information with engineers and other technical team members to augment ...

Advanced Supported Liquid Membranes for Carbon Dioxide Control in Extravehicular Activity Applications

Wickham, David T.; Gleason, Kevin J.; Engel, Jeffrey R.; Cowley, Scott W.; Chullen, Cinda (44th International Conference on Environmental Systems, 2014-07-13)

Developing a new, robust, portable life support system (PLSS) is currently a high priority for NASA in order to support longer and safer extravehicular activity (EVA) missions. One of the critical PLSS functions is maintaining ...

Continued Development of the Rapid Cycle Amine System for Advanced Extravehicular Activity Systems

Papale, William; Chullen, Cinda; Campbell, Colin; Conger, Bruce; McMillin, Summer (44th International Conference on Environmental Systems, 2014-07-13)

Development activities related to the Rapid Cycle Amine (RCA) Carbon Dioxide and Humidity control system have progressed to the point of integrating the RCA into an advanced Portable Life Support System (PLSS) 2.0 to ...

Carbon-Based Regenerable Sorbents for the Combined Carbon Dioxide and Ammonia Removal for the Primary Life Support System (PLSS)

Wójtowicz, Marek A.; Cosgrove, Joseph E.; Serio, Michael A.; Manthina, Venkata; Singh, Prabhakar; Chullen, Cinda (44th International Conference on Environmental Systems, 2014-07-13)

Results are presented on the development of reversible sorbents for the combined carbon dioxide and trace-contaminant (TC) removal for use in Extravehicular Activities (EVAs). Since ammonia is the most important TC to be ...

Next Generation Life Support Project Status

Barta, Daniel J.; Chullen, Cinda; Vega, Leticia; Cox, Marlon R.; Aitchison, Lindsay T.; Lange, Kevin E.; Pensinger, Stuart J.; Meyer, Caitlin E.; Flynn, Michael; Richardson, Tra-My Justine; Jackson, W. Andrew; Abney, Morgan B.; Birmele, Michele N.; Lunn, Griffin M.; Wheeler, Raymond M. (44th International Conference on Environmental Systems, 2014-07-13)

Next Generation Life Support (NGLS) is one of more than 20 technology development projects sponsored by NASA’s Game Changing Development Program. The NGLS Project develops selected life support technologies needed for ...

Compact Multi-gas Monitor for Life Support Systems Control in Space: Evaluation Under Realistic Environmental Conditions

Alonso, Jesús Delgado; Phillips, Straun; Chullen, Cinda; Mendoza, Edgar (44th International Conference on Environmental Systems, 2014-07-13)

Advanced space life support systems require lightweight, low-power, durable sensors for monitoring critical gas components. A luminescence-based optical flow-through cell to monitor carbon dioxide, oxygen, and humidity has ...
