Item "Getter" Development for International Space Station Sabatier Assembly(51st International Conference on Environmental Systems, 7/10/2022) Yu, Ping; Woods, Julius; Corcoran, Matthew; Monje, Oscar; Finn, Riley; Perry, Jay; Kayatin, Matthew; Gavin, Lynda; Garr, John; Walker, StephanieThe Sabatier Assembly (SA) P/N SV1015510-1 was designed by Collins Aerospace to partially close the life support loop on ISS by reacting two waste gases (carbon dioxide and hydrogen) to form water (and waste methane). Waste CO2 is recovered by the Carbon Dioxide Recovery Assembly (CDRA) and waste H2 comes from the Oxygen Generation System (OGS). By recycling these waste gases, the SA reduces the need to launch excess water from earth ground. The SA was successfully launched in 2010 and remained in operation until October 2017. it had produced approximately 1081 liters of water. During the last year of operation, the Sabatier on?orbit unit began to show significant signs of degradation in the reactor which required increasingly involved procedures to restart the reaction after a shutdown. Eventually the SA was deactivated and returned to Collins for Test, Teardown and Evaluation (TT&E). In 2018, Collins performed a TT&E on the SA. TT&E results indicated that the primary source of degradation in the Sabatier system was due to contamination. In specific, the Reactor had become significantly poisoned with sulfur, silicon, fluorine, and chlorine which caused the active sites within the reactor to become inactive. Upon completion of the TT&E, a list of upgrades were recommend for a Sabatier 2.0 design. An upgraded Sabatier 2.0 system would be used to support Exploration demonstration hardware on ISS and beyond. One of the primary recommendations was to incorporate a �getter� sorbent bed. Collins has since worked with KSC, MSFC and JSC to develop the �getter� sorbent bed component for loading upstream of Sabatier reactor with a goal to provide a protection to the reactor from contamination and to extend its service life. This paper describes the joint efforts in developing a suitable Sabatier �getter�.Item International Space Station as a Testbed for Exploration Environmental Control and Life Support Systems - 2020 Status(2020 International Conference on Environmental Systems, 2020-07-31) Shaw, Laura; Garr, John; Gavin, Lynda; Matty, Christopher; Ridley, Alesha; Salopek, Michael; Toon, KatherineHuman exploration missions beyond low earth orbit present significant challenges to spacecraft system design and supportability. A particularly challenging area is the Environmental Control and Life Support System that maintains a habitable and life-sustaining environment for crewmembers. NASA is utilizing the experience gained from its current and prior spaceflight programs to mature life support technologies for exploration missions to deep space. The intent is to establish a portfolio of life support system capabilities with proven performance and reliability to enable human exploration missions and reduce risk to success of those missions. As a fully operational human-occupied platform in microgravity, the International Space Station presents a unique opportunity to act as a testbed for exploration-class Environmental Control and Life Support Systems, such that these systems may be tested, proven, and refined for eventual deployment on deep space human exploration missions. This paper will provide an updated status on the testbed development including hardware and ISS vehicle integration progress to date as well as future plans for efforts to design, select, build, test and fly Exploration Environmental Control and Life Support Systems on the International Space Station.Item International Space Station as a Testbed for Exploration Environmental Control and Life Support Systems - 2024 Status(2024 International Conference on Environmnetal Systems, 2024-07-21) Ridley, Alesha; Hornyak, David; Gavin, Lynda; Garr, John; Caradec, Paul; Toon, Katherine; Brown, Christopher; Korona, Adam; Williams, AllenHuman exploration missions beyond low earth orbit, such as NASA�s Artemis Program, present significant challenges to spacecraft system design and supportability.
