Hydrogen Purification and Recycling for an Integrated Oxygen Recovery System Architecture
(46th International Conference on Environmental Systems, 2016-07-10)
The United States Atmosphere Revitalization life support system on the International Space Station (ISS) performs several services for the crew including oxygen generation, trace contaminant control, carbon dioxide (CO2) ...
Expanded Set of Criteria for Life Support Comparative Assessment
(49th International Conference on Environmental Systems, 2019-07-07)
Currently the primary evaluation scheme for comparison of life support systems is Equivalent System Mass (ESM). ESM can be used to identify the most efficient or least costly-to-launch option when selecting a solution from ...
Characterizing Cryogenic Carbon Dioxide Capture for Life Support Systems
(47th International Conference on Environmental Systems, 2017-07-16)
Without a vastly improved cabin air CO2 removal system technology, deep space missions will not be plausible. The carbon dioxide removal assembly (CDRA) on ISS has repeated replacement and maintenance costs due to adsorbent ...
Commercial EVA Space Suit System Development
(49th International Conference on Environmental Systems, 2019-07-07)
Final Frontier Design (FFD) is in development of their EVA space suit system. The philosophy is to develop a simple, light weight, low cost, and limited use EVA system with a maximum use of 20 EVAs and no return-to-Earth ...
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 ...
Lunar EVA Emergency Pressurization (LEEP) Shelter: Concept Design Using a Systems Engineering Approach
(48th International Conference on Environmental Systems, 2018-07-08)
The European Space Agency has a vision for a collaborative multi-national village to establish a long-term human settlement on the Moon, building on the legacy established by ISS operations. Medical planning and life support ...
Design and Implementation of Combination Charcoal and HEPA Filters for the International Space Station Cabin Air Ventilation System
(49th International Conference on Environmental Systems, 2019-07-07)
The International Space Station (ISS) was designed to have the cabin air filtered through High Efficiency Particulate Air (HEPA) filters which filter out particles and bacteria to protect the crew and downstream condensing ...
Exploration Portable Life Support System Hatch Component Implementation and Testing
(50th International Conference on Environmental Systems, 7/12/2021)
NASA has plans to go back to the Moon. In order to do this, a new spacesuit is being designed for microgravity, cislunar, and lunar surface exploration. The design for the Exploration Extravehicular Mobility Unit (xEMU) ...
Liquid Behavior through a Capillary Microchannel Contactor in a Reduced Gravity Aircraft
(47th International Conference on Environmental Systems, 2017-07-16)
A reliable, efficient, cost-effective carbon dioxide (CO2) removal and dehumidification system is needed for deep space exploration. Current CO2 removal technology on the International Space Station (ISS) utilizes solid ...
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 ...
