What is the role of Astronaut? - Delhi

The word “astronaut,” which is derived from the Greek words for “star” and “sailor,” is frequently used to refer to someone who has traveled to another planet. More precisely, in the West, the term “astronaut” refers to space travelers from the United States, Canada, Europe, and Japan. The term “cosmonaut” (from the Greek words for “universe” and “sailor”) refers to those people from the Soviet Union and afterward from Russia who journey into space. In Russia, space travelers from all countries are called “cosmonauts.” Chinese astronauts are sometimes referred to as taikonauts in the West (from the Greek word for “sailor” and the Chinese word for “space”), but the term “yuhangyuan” (from the Chinese terms for “space” and “traveler”) is used in China.
