Test data from this project will be used in models to help predict the total mass, power, and volumes associated with various ISRU applications and architectures. The final product will be a fully functional system that will be integrated into an end-to-end ISRU propellant production demonstration.","description":"Rocket propellant can be produced anywhere that water is found by splitting it into hydrogen and oxygen, potentially saving several tons of mass per mission and enabling the long term presence of humans in space beyond LEO. When water is split into hydrogen and oxygen, the gaseous products can be very humid (several thousand ppm). Propellant-grade gases need to be extremely dry before being converted into cryogenic liquids. The primary objective of this project is to design, build and test a regenerative gas drying system that can take humid gas from a water electrolysis system and provide dry gas to the inlet of a liquefaction system for long durations. State of the art work in this area attempted to use vacuum as a means to regenerate desiccant, but it was observed that water would migrate to the dry zone without a sweep gas present to direct the desorbed vapor. Further work attempted to use CO2 as a sweep gas, but this resulted in a corrosive carbonic acid. In order for in-situ propellant production to work, we need a way to continuously dry humid gas that addresses these issues.","startYear":2015,"startMonth":10,"endYear":2016,"endMonth":9,"statusDescription":"Completed","principalInvestigators":[{"contactId":875,"canUserEdit":false,"firstName":"Aaron","lastName":"Paz","fullName":"Aaron Paz","fullNameInverted":"Paz, Aaron","primaryEmail":"aaron.paz-1@nasa.gov","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":335305,"canUserEdit":false,"firstName":"Michael","lastName":"Lapointe","fullName":"Michael R Lapointe","fullNameInverted":"Lapointe, Michael R","middleInitial":"R","primaryEmail":"michael.r.lapointe@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":392233,"canUserEdit":false,"firstName":"Richard","lastName":"Howard","fullName":"Richard W Howard","fullNameInverted":"Howard, Richard W","middleInitial":"W","primaryEmail":"richard.w.howard@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62108,"canUserEdit":false,"firstName":"Carlos","lastName":"Westhelle","fullName":"Carlos H Westhelle","fullNameInverted":"Westhelle, Carlos H","middleInitial":"H","primaryEmail":"carlos.h.westhelle@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[],"responsibleMd":{"acronym":"STMD","canUserEdit":false,"city":"","external":false,"linkCount":0,"organizationId":4875,"organizationName":"Space Technology Mission Directorate","organizationType":"NASA_Mission_Directorate","naorganization":false,"organizationTypePretty":"NASA Mission Directorate"},"program":{"acronym":"JSC CIF","active":true,"description":"
JSC provides and applies its preeminent capabilities in science and technology to develop, operate, and integrate human exploration missions. The Center encourages collaboration with aerospace and non-aerospace industries, government agencies, and academia to solve science and technology challenges, while actively striving to maximize technology transfer into the commercial sector.
An active and sustainable science and technology development program is key to ensuring the challenges of human exploration are successfully overcome. The JSC-directed solicitations program enables the Center to invest strategically in high priority areas needed to accomplish future missions as articulated in the NASA Technology Roadmaps and the Space Technology Investment Plan (STIP). It offers the Center the ability to address technology gaps that are beyond the requirements of near-term programs to fund. It also provides a platform to continue to grow and maintain critical skills and innovations needed to ensure future mission success. These solicitations encourage use of collaborations to ensure maximum benefit to both the space program and the nation. As such, external partnerships are highly encouraged not only as a funding leverage but to bring innovative ideas and approaches into human exploration programs.
Selection Process
Typically, JSC solicitations are developed by the JSC CTO and the JSC Technology Working Group (JTWG). The competitive calls are coordinated with JSC Senior Staff and communicated to the JSC workforce via internal email distribution to an R&D community list and through postings on the internal center website and through JSC Today notices.
The JTWG solicits, evaluates and prioritizes all JSC solicitation responses in a two-stage process. The JTWG members review project proposals and work together to down-select to the finalists. The Principal Investigators (PIs) make presentations to the JTWG to provide more in-depth project details. This allows the members to select the finalists to support for the year. Selection criteria and funding vary based on the focus of the solicitation but of primary interest are:
Project Accomplishments
Through the result of research and development, JSC’s IR&D project PIs are making important progress in the advancement of technology needed to enable NASA’s mission of space exploration. In addition, many of the technologies development to meet the challenges of space exploration have great commercialization potential. Each year, many of JSC’s IR&D projects file New Technology Reports (NTRs) through the JSC Tech Transfer Office. Several of these reports have received New Technology Evaluation Patent ratings to pursue patents, while additional ones have been scheduled for success story articles to be written and published.
JSC projects active in FY12 and beyond have been included in TechPort. Through the TechPort tool information on the projects is provided and will be updated by PIs as developments and updates become available. This will offer further knowledge and information sharing between NASA developers, researchers, engineers and scientists and other internal and external stakeholders.
The JSC Chief Technologist Office (CTO) sponsors one or more Independent Research & Development (IR&D) solicitations throughout each year depending on available funds. These local solicitations primarily use a blend of Agency Center Innovation Fund (CIF) and the JSC Center Investment Account (CIA) funds to stimulate and encourage technology development, creativity, and innovation. The objective is to address the technology needs of the Agency as well as the nation. For these reasons, funds distributed to JSC support emerging technologies and creative initiatives that leverage the Center’s talent pool and unique capabilities. Scientists and engineers across the Center lead projects and establish partnerships between other centers, agencies, research laboratories, academic institutions and private industries.
