iss064e016385 (Dec. 29, 2020) --- NASA astronaut and Expedition 64 Flight Engineer Shannon Walker sets up hardware inside the Microgravity Science Glovebox for the Solidification Using a Baffle in Sealed Ampoules (SUBSA) experiment. SUBSA crystallizes melts in microgravity to learn more about the process of semiconductor crystal growth to benefit Earth and space industries. Results may lead to reduced fluid motion in the melt, leading to better distribution of subcomponents and the potential for improved technology used in producing semiconductor crystals.
