The additional characterization may feedback into the design of the next generation of on-orbit experiments for soldering, essential for future long-duration human exploration missions. The proposed work would apply advanced 3D materials characterization to solder samples from ISSI and non-ISSI compositions. One of the selected studies will use In-Space Soldering Investigation (ISSI) experiment to investigate and improve our understanding of how porosity develops in the solder joints, how it is influenced by gravity, and how solder joints properties and functions are affected. The online database contains data from completed physical science reduced-gravity flight experiments conducted on the International Space Station, Space Shuttle flights, free flying spacecraft, commercial cargo flights to and from the space station, or from related ground-based studies. Researchers will investigate important problems with existing data from NASA’s Physical Sciences Informatics (PSI) system. These five research projects, involving recognized experts in the fields of combustion science, complex fluids, fluid physics, informatics, and materials science, will use data contained in the PSI system and build on prior reduced-gravity research to advance fundamental research in the physical sciences. This program element is part of Science Mission Directorate (SMD) Research Opportunities in Space and Earth Sciences - 2021 (ROSES-2021) solicitation. NASA’s Physical Sciences Research Program has selected five ground-based proposals in response to the Physical Sciences Informatics System call for proposals. Proposals selected from the Physical Sciences Informatics program element extend the use of data gathered on the International Space Station (ISS).
