Knowra Space medicine Space medicine Space medicine studies how spaceflight affects human health and provides care before, during, and after missions. It addresses the physiological and psychological demands of living and working in space.
Microgravity : A condition in which objects and people appear to experience near-weightlessness because they are in free fall. It drives fluid shifts, muscle loss, and other major physiological changes during spaceflight.
Astronaut medical selection : The medical assessment used to determine whether candidates can safely meet the demands of astronaut training and spaceflight. Selection reduces mission health risks while accounting for demanding, sometimes inaccessible care.
Aerospace physiology : The study of how the human body responds to conditions encountered in aviation and spaceflight. It supplies the physiological foundation for understanding health changes in orbit.
Human Mars mission : A crewed expedition to Mars, involving interplanetary travel and operations on the planet. Its duration and distance from Earth intensify radiation, isolation, and emergency-care problems.
Space radiation : Energetic particles and electromagnetic radiation found in space, including galactic cosmic rays and solar particle events. Exposure raises cancer risk and can damage tissues, complicating mission planning and medical care.
Spaceflight medical monitoring : The collection and interpretation of health data from crew members before, during, and after space missions. Monitoring detects changes early and helps flight teams adjust care and countermeasures.
Human factors and ergonomics : The study of how people interact with tools, tasks, environments, and organizations. Medical procedures and equipment must fit crew abilities, workload, and spacecraft design.
Deep space radiation : Radiation exposure beyond Earth's protective magnetosphere, including galactic cosmic rays and solar particle events. The health effects of prolonged exposure remain a major constraint on crewed exploration.
Spaceflight-associated neuro-ocular syndrome : A collection of eye and brain changes observed in some astronauts after long-duration spaceflight. Its visual and structural effects illustrate how fluid shifts can affect the head and eyes.
Remote medical care : Clinical assessment and treatment provided when patients and medical professionals are separated by distance. Crew members may need onboard care guided remotely by Earth-based clinicians.
