The Expedition 74 crew on the International Space Station has been focusing on medical tests and microbiology, as well as working on spacesuits, cargo operations, and life support maintenance. NASA flight engineer Chris Williams began his shift drawing a blood sample from NASA flight Engineer Jessica Meir for processing in a centrifuge and preservation in a science freezer for analysis. Williams also processed his urine samples for the CIPHER study, which measures astronaut health before, during, and after a spaceflight. Roscosmos flight engineer Andrey Fedyaev primarily worked on orbital plumbing duties. The European Space Agency's Sophie Adenot also worked on cargo consolidation to optimize space inside the Columbus laboratory module.
