Médecine spatiale

Space medicine is a specialized field, which developed from Aerospace medicine, that focuses on the acute medical care of astronauts and spaceflight participants. The spaceflight environment poses many unique stressors to the human body, including G forces, microgravity, unusual atmospheres such as low pressure or high carbon dioxide, and space radiation. Space medicine applies emergency medicine, acute care medicine, critical care medicine, interventional radiology, radiology, austere medicine, and toxicology perspectives treat and prepare for medical problems in space. This expertise is then used to inform vehicle systems design to minimize the risk to human health and performance while meeting mission objectives. Astronautical hygiene is the application of science and technology to the prevention or control of exposure to the hazards that may cause astronaut ill health. Both these sciences work together to ensure that astronauts work in a safe environment. Medical consequences such as possible blindness and bone loss have been associated with human spaceflight. In October 2015, the NASA Office of Inspector General issued a health hazards report related to space exploration, including a human mission to Mars. Hubertus Strughold (1898–1987), a former Nazi physician and physiologist, was brought to the United States after World War II as part of Operation Paperclip. He first coined the term "space medicine" in 1948 and was the first and only Professor of Space Medicine at the School of Aviation Medicine (SAM) at Randolph Air Force Base, Texas. In 1949, Strughold was made director of the Department of Space Medicine at the SAM (which is now the US Air Force School of Aerospace Medicine (USAFSAM) at Wright-Patterson Air Force Base, Ohio. He played an important role in developing the pressure suit worn by early American astronauts. He was a co-founder of the Space Medicine Branch of the Aerospace Medical Association in 1950.

Apesanteur
L'apesanteur ou impesanteur est l'état d'un système dans lequel aucune accélération, causée par la gravitation ou toute autre force, ne peut être mesurée par un observateur dans le système en question. Cela inclut les situations de chute libre, mais aussi les situations où le système est suffisamment éloigné de toute source de gravité pour que celle-ci puisse être négligée. Cette situation se traduit par une absence de poids (mais la masse reste inchangée).
Astronautical hygiene
Astronautical hygiene evaluates, and mitigates, hazards and health risks to those working in low-gravity environments. The discipline of astronautical hygiene includes such topics as the use and maintenance of life support systems, the risks of the extravehicular activity, the risks of exposure to chemicals or radiation, the characterization of hazards, human factor issues, and the development of risk management strategies. Astronautical hygiene works side by side with space medicine to ensure that astronauts are healthy and safe when working in space.
Visual impairment due to intracranial pressure
Spaceflight-associated neuro-ocular syndrome (SANS), previously known as Spaceflight-induced visual impairment, is hypothesized to be a result of increased intracranial pressure (ICP). The study of visual changes and ICP in astronauts on long-duration flights is a relatively recent topic of interest to space medicine professionals. Although reported signs and symptoms have not appeared to be severe enough to cause blindness in the near term, long term consequences of chronically elevated intracranial pressure are unknown.
