Item Functional Interface Considerations within an Exploration Life Support System Architecture(46th International Conference on Environmental Systems, 2016-07-10) Perry, Jay; Sargusingh, Miriam; Toomarian, NikzadAs notional life support system (LSS) architectures are developed and evaluated, myriad options must be considered pertaining to process technologies, components, and equipment assemblies. Each option must be evaluated relative to its impact on key functional interfaces within the LSS architecture. A leading notional architecture has been developed to guide the path toward realizing future crewed space exploration goals. This architecture is described and its developmental status is summarized. Important interfaces within the architecture are discussed and the role of environmental monitoring within the architecture is described. A preliminary hazard analysis of the architecture is also presented.Item NASA Environmental Control and Life Support (ECLS) Technology Development and Maturation for Exploration: 2015 to 2016 Overview(46th International Conference on Environmental Systems, 2016-07-10) Schneider, Walter; Gatens, Robyn; Anderson, Molly; Broyan, James; Macatangay, Ariel; Shull, Sarah; Perry, Jay; Toomarian, NikzadOver the last year, NASA has continued to refine the understanding and prioritization of technology gaps that must be closed in order to achieve Evolvable Mars Campaign objectives. These efforts are reflected in updates to the technical area roadmaps released by NASA in 2015 and have guided technology development and maturation tasks that have been sponsored by various programs. This paper provides an overview of the refined Environmental Control and Life Support (ECLS) strategic planning, as well as a synopsis of key technology and maturation project tasks that occurred in 2015 and early 2016 to support the strategic needs. Plans for the remainder of 2015 and subsequent years will also be described.Item NASA Environmental Control and Life Support (ECLS) Technology Development and Maturation for Exploration: 2016 to 2017 Overview(47th International Conference on Environmental Systems, 2017-07-16) Anderson, Molly; Broyan, James; Gatens, Robyn; Macatangay, Ariel; Perry, Jay; Schneider, Walter; Toomarian, NikzadNational Aeronautics and Space Administration (NASA)’s life support community has made significant progress in the last year advancing key technologies and capabilities to enable future exploration missions. Technology gap identification and prioritization has remained fairly consistent. The development teams have completed key development milestones to prove or disprove the feasibility of new technology. Decisions were made to narrow technology options and even make the first selections for technologies that will be demonstrated at full scale on the International Space Station (ISS). Detailed planning for integrated system demonstrations on ISS has begun. Also, other activities began to investigate the ECLS system design and integration considerations for development of capabilities for the cislunar proving ground. This paper provides an overview of the refined Environmental Control and Life Support (ECLS) strategic planning, and overall roadmap updates, as well as a synopsis of key technology and maturation project tasks that occurred in 2016 and early 2017 to support the strategic needs. Plans for the remainder of 2017 and subsequent years are also described.Item NASA Environmental Control and Life Support Technology Development and Maturation for Exploration: 2017 to 2018 Overview(48th International Conference on Environmental Systems, 2018-07-08) Sargusingh, Miriam; Anderson, Molly; Perry, Jay; Gatens, Robyn; Broyan, James; Macatangay, Ariel; Schneider, Walter; Toomarian, NikzadOver the last year, the National Aeronautics and Space Administration (NASA) has made steps towards defining a path for extending human presence beyond low Earth orbit. The environmental control and life support (ECLS) technology gap identification and prioritization has remained fairly consistent throughout the past year during which the ECLS community has continued to refine and execute the plan for advancing key technologies and capabilities that enable future exploration missions. The development teams have completed key milestones, moving toward prototypes for ground and on-orbit demonstration. Detailed planning for integrated system demonstrations on ISS has continued. Studies to refine deep space exploration requirements, design and integration considerations were performed. Of particular concern for the emerging deep space exploration architecture was consideration of long-duration intermittent dormancy. This paper provides an overview of the refined ECLS strategic planning and overall roadmap updates as well as a synopsis of key technology and maturation project tasks that occurred in 2017 and early 2018 to support the strategic needs. Plans for the remainder of 2018 and subsequent years are also described.Item NASA Environmental Control and Life Support Technology Development and Maturation for Exploration: 2018 to 2019 Overview(49th International Conference on Environmental Systems, 2019-07-07) Anderson, Molly; Sargusingh, Miriam; Gatens, Robyn; Perry, Jay; Schneider, Walter; Macatangay, Ariel; Toomarian, Nikzad; McKinley, Melissa; Shaw, LauraNASA’s Environmental Control and Life Support (ECLS) technology development projects have reached important milestones in 2018 and 2019, that represent vital steps toward establishing readiness for the next generation of human space exploration missions. Some of the first technology demonstration systems were delivered for testing and evaluation aboard the International Space Station (ISS). Key reviews have been completed for other systems, and the ISS team is planning for the complex challenges of integrating the multiple technology demonstrations with upgraded ISS systems on orbit. In parallel, planning is beginning for ground testing to be conducted that strategically complements the on-orbit demonstrations. Analyses of reliability and supportability are being considered for their impact on subsystem and system design as well. Outside of the technology development projects, the Gateway program has also defined more detailed plans and schedules, which aid the ECLS community in developing more detailed functional and performance requirements for technolog, and requires the ECLS community to respond with strategies for deploying an early open-loop functional capability that can evolve to provide improved capabilities or greater loop closure. As these plans mature, NASA is also considering where disruptive technologies may provide value, and determining what new gaps or new details may emerge for future missions. This paper provides an overview of the refined ECLS strategic planning and overall roadmap updates as well as a synopsis of key technology and maturation project tasks that occurred in 2018 and early 2019 to support the strategic needs. Plans for the remainder of 2019 and subsequent years are also described.Item NASA Environmental Control and Life Support Technology Development and Maturation for Exploration: 2019 to 2020 Overview(2020 International Conference on Environmental Systems, 2020-07-31) Schneider, Walter; Perry, Jay; Broyan, James; Macatangay, Ariel; McKinley, Melissa; Meyer, Caitlin; Owens, Andrew; Toomarian, Nikzad; Gatens, RobynDuring 2019 and 2020, NASA’s Environmental Control and Life Support (ECLS) technology development projects have taken vital steps toward establishing readiness for the next generation of human space exploration missions. Technology demonstration systems from last year have been operated on the International Space Station (ISS) and others have been launched. Development of future technology demonstrations is on-going. Facility and hardware development for ground testing to be conducted that strategically complements the on-orbit demonstrations and some ground testing has been initiated. Reliability studies have started to define requirements for on-orbit and ground testing and other investments to support exploration missions. These efforts support NASA missions beyond LEO and include Gateway, lunar surface, Mars transportation, and Mars surface. This paper provides an overview of the current ECLS strategic planning and roadmap as well as a synopsis of key technology and maturation project tasks that occurred in 2019 and early 2020 to support the strategic needs. Plans for the remainder of 2020 and subsequent years are also described.
