The Utilization of Urine Processing for the Advancement of Life Support Technologies
(44th International Conference on Environmental Systems, 2014-07-13)
The success of long-duration missions will depend on resource recovery and the self- sustainability of life support technologies. Current technologies used on the International Space Station (ISS) utilize chemical and ...
International Space Station Potable Water Characterization for 2013
(44th International Conference on Environmental Systems, 2014-07-13)
In this post-construction, operational phase of International Space Station (ISS) with an ever-increasing emphasis on its use as a test bed for future exploration missions, the ISS crews continue to rely on water reclamation ...
A novel ion exchange system to purify mixed ISS waste water brines for chemical production and enhanced water recovery
(44th International Conference on Environmental Systems, 2014-07-13)
The International Space Station water recovery system produces a sizable portion of waste water brine. This brine is highly toxic and contains a significant volume of water. With new biological techniques that do not require ...
Characterization of Potassium Superoxide and a Novel Packed Bed Configuration for Closed Environment Air Revitalization
(44th International Conference on Environmental Systems, 2014-07-13)
Potassium superoxide (KO2) has been used in environmental control and life support systems (ECLSS) ranging from early Soviet spacecraft to self-contained self-rescuer devices for mine safety. By reacting with moisture ...
Trash-to-Gas: Determining the Ideal Technology for Converting Space Trash into Useful Products
(44th International Conference on Environmental Systems, 2014-07-13)
The goal of the Trash-to-Gas project is to develop space technology alternatives for converting trash and other human spaceflight waste materials into high-value products. A major milestone for this task was to select one ...
Launch Vehicle Avionics Passive Thermal Management
(44th International Conference on Environmental Systems, 2014-07-13)
A passive thermal management system was designed to cool avionics on a launch vehicle for 3 different thermal modes. Prior to launch, the heat sink for the avionics is purge duct flow. During the 10 minute launch period, ...
CO2 Reduction Assembly Prototype using Microlith-based Sabatier Reactor for Ground Demonstration
(44th International Conference on Environmental Systems, 2014-07-13)
The utilization of CO2 to produce life support consumables, such as O2 and H2O, via the Sabatier reaction is an important aspect of NASA’s cabin Atmosphere Revitalization System (ARS) and In-Situ Resource Utilization (ISRU) ...
A Method for Capturing, Tracking and Ranking the Relative Competitiveness of Competing Alternatives
(44th International Conference on Environmental Systems, 2014-07-13)
An “old” and “new” method for ranking competing alternatives by capturing and tracking success criteria at the requirements level is proposed. The established old method of Quality Function Deployment (QFD) is reviewed and ...
Development of Carbon Dioxide Removal Systems for Advanced Exploration Systems 2013-2014
(44th International Conference on Environmental Systems, 2014-07-13)
The Atmosphere Revitalization Recovery and Environmental Monitoring (ARREM) project was initiated in September of 2011 as part of the Ad- vanced Exploration Systems (AES) program. Under the ARREM project, CO2 removal and ...
Phase Change Material for Temperature Control of Imager or Sounder on GOES Type Satellites in GEO
(44th International Conference on Environmental Systems, 7/13/2014)
This paper uses phase change material (PCM) in the scan and telescope cavities of an imager or sounder on satellites in geostationary orbit (GEO) to maintain the telescope temperature stable. When solar flux entering the ...
