"Spaceman" is a more colloquial term that can refer to astronauts or to anyone who travels in space, including cosmonauts (from Russia) and taikonauts (from China). In general, "astronaut" is the more formal and widely recognized term, while "spaceman" is more informal and can be used in a broader sense.
Those Soviet and later Russian individuals who travel into space are known as cosmonauts (from the Greek words for universe  and sailor ). China designates its space travelers taikonauts (from the Chinese word for space  and the Greek word for sailor ). #2 by daedalus1 on 16 Mar, 2024 09:55.
