iss064e032426 (Feb. 12, 2021) — NASA astronaut and Expedition 64 Flight Engineer Michael Hopkins swaps samples inside the Microgravity Science Glovebox for the SUBSA (Solidification Using Baffles in Sealed Ampoules) experiment. The SUBSA physics study explores experimental methods of crystallizing melts in microgravity that may contribute to the production of higher quality semiconductor crystals.
