NASA announced a series of biomedical and human performance investigations to be conducted during the SpaceX Crew-13 mission aboard the International Space Station, including a new study on how spaceflight affects blood flow and clotting, along with tests of piloting skills and countermeasures for vision and brain changes. The research aims to better understand and mitigate the physiological risks of long-duration spaceflight ahead of future deep space missions.
