Preliminary Study of CO2 Electrolysis in Ionic Liquid
(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% ...
Defining ECLSS Robustness for Deep Space Exploration
(47th International Conference on Environmental Systems, 2017-07-16)
Human exploration of deep space will require Environmental Control and Life Support Systems of increasing dependability as mission duration and distance from Earth increases. As crews travel to distant unexplored environments, ...
The Status of JAXA’s Water Recovery System
(48th International Conference on Environmental Systems, 2018-07-08)
Water Recovery System (WRS) is a key-technology for future manned space exploration. JAXA aims at the higher water recovery rate than the current ISS system with no consumable supplies in order to reduce water replenishment. ...
Investigation of Desiccants and CO2 Sorbents for Exploration Systems 2016-2017
(47th International Conference on Environmental Systems, 2017-07-16)
NASA has embarked on the mission to enable humans to explore deep space, including the goal of sending humans to Mars. This journey will require significant developments in a wide range of technical areas as resupply and ...
Heat Melt Compactor Gas Contaminants from Single Waste Materials
(48th International Conference on Environmental Systems, 2018-07-08)
A Heat Melt Compactor (HMC) has been under development by NASA in recent years as a technology for processing space mission trash. The HMC compacts the trash, heats the trash to 150 C, sterilizes the trash, and recovers ...
Water Removal Performance Degradation of Nafion Due to Ammonia Loading in Representative Orbital Environments
(49th International Conference on Environmental Systems, 2019-07-07)
The Boeing Company (Boeing) CST-100 Starliner spacecraft utilizes the patented Humidity Control Subassembly (HCS) designed and manufactured by Paragon Space Development Corporation (Paragon) to control cabin atmospheric ...
Logistics Modeling and Simulation for Lunar and Mars Mission Architecture Analysis
(50th International Conference on Environmental Systems, 7/12/2021)
Commercial space launch companies have been drastically decreasing their launch costs in recent years. This may change space logistics for future lunar and Mars missions. In the Artemis plan, the lunar gateway located in ...
International Space Station (ISS) Environmental Control and Life Support (ECLS) System Overview of Events 2018-2019
(49th International Conference on Environmental Systems, 2019-07-07)
Nov 20th, 2018 marks the 20th anniversary of the beginning of construction of the International Space Station. Major events include NASA direction to study system dormancy as it would relate to a short term de-crewing of ...
Particle Loading Tests on HEPA Flat Sheet Media at Sub-Ambient Pressures Using a Lunar Dust Simulant
(50th International Conference on Environmental Systems, 7/12/2021)
When humans return to the moon under NASA�s Artemis program, their activities on the lunar surface will inevitably lead to the intrusion of some level of lunar dust into the lander cabin and subsequently its potential ...
Incorporation of Planetary Protection Knowledge Gaps into Agency Capability Development Planning
(50th International Conference on Environmental Systems, 7/12/2021)
Since its start in 2016, the COSPAR workshop series on "Planetary protection requirements for human extraterrestrial missions" has generated and refined a set of planetary protection (PP) knowledge gaps (KGs) which, if ...
