Crew-12 to Probe How Microgravity Changes the Human Body on ISS

NASA’s SpaceX Crew-12 will conduct long‑duration ISS studies on how the body adapts to microgravity, including the Venous Flow study to assess blood circulation and clot risk, a Manual Piloting exercise simulating Moon landings to test disorientation and control after gravity shifts, and a vitamin B trial for spaceflight‑associated neuro‑ocular syndrome (SANS), with preflight, in‑flight, and postflight measurements to guide future Artemis missions and crew safety.
