(also astronaut), a person who tests and operates space hardware during a space flight; it is a profession that arose because of man’s penetration into space (1961).

The first cosmonaut trainees were selected from military pilots (USSR) and test pilots (USA), since the necessary combination of qualities (expert flying skill; the ability to make instant decisions and to withstand noise, vibration, acceleration, and their combinations; and experience in carrying out observations and recording their results) is most often found in those professions. Later, in both the USSR and the USA, engineers and scientists with the required specialized knowledge also became part of flight crews.

Cosmonaut training began in the Soviet Union in 1960 and in the USA in 1959 for Mercury program flights and in 1962 for Gemini and Apollo program flights.
