NASA astronaut space wallpaper

Wall Info:

The nationality of NASA astronauts must be American.Because there are a large number of technology patents in the aerospace field, if people from other countries apply for astronauts, they are likely to leak science and technology.Secondly, candidates must have a master's degree in mathematics, computer science, physics, biology, engineering, etc.
