Astronaut training engineers, technicians, pilots, and geologists. In addition there will be a focus on the psychological aspects of long-duration missions where crew is largely isolated. Currently a six-month mission to the ISS requires up to five years of astronaut training. This level of training is to be expected and likely to be expanded upon for future space exploration missions. It may also include in-flight training aspects. It may be possible that the ISS will be used as a long-duration astronaut training facility in the future. A powerful tool for astronaut training will be the continuing use of analog environments, including NASA
Chinese as a foreign language further. In a Biblical vein similar to Kircher's, he tried to demonstrate that Chinese was the Primitive or Adamic language.
