Four astronauts touched down in the Gulf after 240 days aboard the International Space Station. The SpaceX Dragon capsule completed its deorbit burn on 8 October 2026 and NASA declared the mission nominal. Public briefings highlighted smooth recovery and gratitude. Behind those statements, long duration microgravity leaves documented physiological costs that are rarely detailed for public audiences. This report reconstructs the Crew-12 mission timeline, examines publicly acknowledged medical protocols, and outlines four health domains that NASA typically underreports.
