Develop detection and decontamination methods for green ionic propellants on future manned spacecraft. The second phase will investigated material compatibility issues for AF-M-315E and will provide data for system engineers to use. DoD and commercial entities can use these methods and data. The JANNAF Propellant and Explosives Development and Characterization Subcommittee can be a forum for insertion into industry.
","description":"High performance green monopropellants require means of detection and remediation of spills and residues. This project investigated color tests for spill detection and methods for remediation. Innovation was achieved using COTS test kits, and both fundamental and novel chemistry applied to the monopropellant ingredients. The second phase examined candidate materials for use in AF-M315E propulsion systems. Pairs of representative alloys, passivated and native, were immersed in AF-M315E at 71 °C for 31 d, fluid samples were periodically characterized and post-test materials and fluids were finally characterized. Typical corrosion studies use only the total time of immersion; this study also obtained interim data points. The image shows a surface treated alloy on the left and the untreated alloy on the right. Candidate hydrazine alternatives have been developed for spacecraft propulsion. The U.S. Air Force AF-M315E and the Swedish ammonium dinitramide propellants have received the most attention, while ammonium dinitramide propellants are a possible contender. While greenness relates to environmentally benign and relative toxicity, neither of these propellants is completely \"nontoxic\" or completely safe; if their energetic nature was not inherent they would not be used as monopropellants. This is particularly important with ammonium dinitramide (ADN) and hydrazinum nitroformate (HNF) propellants, which ESA and the EU has favored while the U.S. Air Force has focused on AF-M315E and the U.S. Army has investigated hydroxylammonium nitrate/triethanolammonium nitrate (HAN/TEAN; XM-46) propellants. The first phase of the project's focus will be to evaluate detection and decontamination methods for these propellants.

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.
