Optimized Phase Change Material Module for Thermal Regulation of Cycled Dissipative Units 

Dudon, Jean-Paul; Raynaud, Martin; Bosse, Julien; Atinsounon, Paul; Ferrier, Michele; Valentini, David; Blanc, Gilles (49th International Conference on Environmental Systems, 2019-07-07)
Phase Change Materials are very good candidates to smooth temperature variations of units which undergo thermal cycling dissipations or external cycling thermal loads. They can also be used to damped fast but short thermal ...

Membrane Distillation Bags for Water Recovery in Trash Compaction and Processing Systems 

Rangan, Krishnaswamy; Coppage-Gross, Jacob; Terrazas, Jordan; McHale, Michael; Sudarshan, Tirumalai (49th International Conference on Environmental Systems, 2019-07-07)
The National Aeronautics and Space Administration’s (NASA) crewed spacecraft use containers to store waste derived from food, water, and other supplies. The trash bags occupy a large volume and present a significant ...

Preliminary Study of CO2 Electrolysis in Ionic Liquid 

Sakurai, Masato; Shima, Asuka; Iwasaki, Kazuyuki; Sometani, Yoshiyuki; Goto, Takuya; Fukunaka, Yasuhiro; Kanakubo, Mitsuhiro (49th International Conference on Environmental Systems, 2019-07-07)
Resources are extremely limited in spacecraft, and oxygen consumed for breathing also needs regeneration. In the system using the current Sabatier reaction (CO2 + 4H2 → CH4 + 2H2O), O2 can only be collected up to about 50% ...

Payload Fairing Geometries as Space Stations with Flexible “Plug and Play” Rack System 

Guzman, Leonardo (49th International Conference on Environmental Systems, 2019-07-07)
This paper outlines a design methodology of adapting launch vehicle payload fairing geometries into pressurized single or multi-element space stations. Large volume, low budget space stations can be achieved through ...

Microalgae-based Photobioreactors for a Life Support System of a Lunar Base 

Martin, Johannes; Detrell, Gisela; Keppler, Jochen; Helisch, Harald; Fasoulas, Stefanos; Ewald, Reinhold (49th International Conference on Environmental Systems, 2019-07-07)
Environmental Control and Life Support Systems (ECLSS) for a crewed lunar base differ from those for Space Stations in Low Earth Orbit (LEO), mainly due to the increased distance, and therefore more expensive resupply ...

Development of Human-Spacesuit Interaction Models 

Jarvis, Sarah; Vu, Linh; Benson, Elizabeth; Rajulu, Sudhakar (49th International Conference on Environmental Systems, 2019-07-07)
Today’s astronaut corps represents a wide range of various anthropometric dimensions. Accommodating this wide range of anthropometry and protecting for size variations in future crews, makes spacesuit sizing and fit a ...

How Much Testing is Needed to Manage Supportability Risks for Beyond-LEO Missions? 

Owens, Andrew; de Weck, Olivier (49th International Conference on Environmental Systems, 2019-07-07)
Supportability will be a significantly greater driver of cost and risk for future deep-space crewed missions than it has been in the past. Spares requirements and maintenance risk mitigation in particular present an ...

Membrane Microgravity Air Conditioner Conceptual Design Progress and Long Duration Test Results 

Fricker, John; Lottridge, Roger; Hansen, Scott (49th International Conference on Environmental Systems, 2019-07-07)
The Membrane Microgravity Air Conditioner (MMAC) is a microgravity compatible condensing heat exchanger for removal of particulates, humidity, and heat from air, with production of clean condensate, leading to possible ...

Exploration PLSS Thermal Desktop Modeling 

Barnes, Bruce; Abraham, Brittany; Miranda, Bruno; Speasmaker, Latham; Nguyen, Quoc (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 ...
