An astronaut (or astronaut) is a person who has been trained in space flight. It can command, pilot or be a member of the spacecraft crew. Today, the term is mostly used for professional space travelers, but often everyone who has traveled into space is called a cosmonaut (scientists, politicians, tourists). The first cosmonaut was Yuri Gagarin. The first woman cosmonaut was Valentina Terješkova. "Astronaut" technically refers to all people who travel to space, regardless of nationality or affiliation; however, astronauts from Russia or the Soviet Union are usually known instead as cosmonauts (from the Russian "cosmos", meaning "space", which is also borrowed from Greek) to distinguish them from American or NATO-related space travelers. The relatively recent development of manned spaceflights by China has led to the rise of the term tycoon (from the Mandarin "tycoon" (太空, meaning "space"), although its use is somewhat informal and the origin is unclear. In mainland China, astronauts of the Astronaut Corps of the People's Liberation Army and their foreign counterparts are officially called hangtjenjuen (航天 员, meaning "celestial navigator" or literally "sky navigation personnel") and "astronauts" in English.
