The coatings with excellent radiation shielding results were sent to the International Space Station as a part of MISSE-17 (Materials International Space Station Experiment) in March 2023[7]. The coatings, mounted on a platform with other testing samples are being exposed to solar and intergalactic cosmic radiation. After six months, a crew of astronauts will bring the material back to Earth for analysis. In the meantime, NASA and FIU will test the coatings against the harsh erosive environment and thermal vacuum cycles. The findings from this study will help develop and construct materials and systems that will be used in Human Landing Systems (HLS) in future lunar explorations, including Artemis missions. ~iTSSe Acknowledgment The authors gratefully acknowledge support from the National Aeronautics and Space Administration (NASA) through the 80MSFC21P0018 grant and Marshall Space Flight Center (MSFC, Huntsville, Ala.).

THE TEAM The coatings were developed as a part of NASA’s Metallic Environmental Resistant Coatings Rapid Innovation Initiative (MERCRII) project. The MERCRII team consists of two NASA centers (NASA Marshall Space Flight Center (MSFC), Huntsville, Ala., and NASA Langley Research Center, Hampton, Va.; the Plasma Forming Laboratory at FIU as an academic partner; and Plasma Processes, Huntsville, Ala., as a private partner. The project is led by Ms. Sara Rengifo, Tribology and Metrology engineer at NASA MSFC and PFL alums. The project is mentored by subject matter experts, including Dr. Cheol Park from NASA Langley Research Center and Dr. Arvind Agarwal from the Plasma Forming Laboratory, FIU. The APS coatings were developed and characterized at FIU’s Plasma Forming Laboratory and the Advanced Materials Engineering Research Institute (AMERI) by Ph.D. candidate Abhijith Sukumaran under the supervision of Professor Arvind Agarwal. The Thermal Spray Society (TSS) is dedicated to the expansion of knowledge, technical information, safety guidelines, and best practices and procedures in this unique and valuable surface application. With an unparalleled international community and network, TSS members have access to a global marketplace that continues to grow.
