This NASA Technical Standard provides medical requirements and clinical procedures designed to ensure crew health and safety and occupational longevity of NASA career astronauts. This NASA Technical Standard is used for selection and annual recertification of astronauts. It reflects the medical requirements to successfully complete specific mission tasks and the multifaceted training and performance required of an astronaut. These include, but are not limited to, flying in high-performance aircraft, exposure to hypobaric and hyperbaric conditions, exposure to unique environments (e.g., microgravity, 1/6 gravity, high g), and conducting specialized operations (e.g., extra-vehicular activities, robotic arm operations).
