Astronaut training describes the complex process of preparing astronauts in regions around the world for their space missions before, during and after the flight, which includes medical tests,[2] physical training,[3]extra-vehicular activity (EVA) training, wilderness survival training , water survival training , robotics training , procedure training, rehabilitation process,[4] as well as training on experiments they will accomplish during their stay in space.
Virtual and physical training facilities have been integrated to familiarize astronauts with the conditions they will encounter during all phases of flight and prepare astronauts for a microgravity environment.[5] Special considerations must be made during training to ensure a safe and successful mission, which is why the Apollo astronauts received training for geology field work on the Lunar surface and why research is being conducted on best practices for future extended missions, such as the trip to Mars.
