What is the difference between a cosmonaut and an astronaut?
Cosmonaut and astronaut are synonyms, that is, theoretically we can use them interchangeably, but traditionally we call people launched into space by the Americans astronauts and by the Russians cosmonauts, regardless of what nationalities they were. That is, Americans, Canadians, Japanese, Italians, French and Germans flying with Americans are astronauts. In contrast, General Hermaszewski, the only (so far) Pole in Space, is called a cosmonaut because he flew as part of the Soviet space program.
