Astronauts

Astronauts are highly trained individuals who travel into space to conduct scientific research, perform missions, and operate spacecraft. They undergo rigorous physical and technical training to prepare for the challenges of space travel, such as weightlessness, isolation, and the technical complexities of operating spacecraft and scientific experiments. Astronauts may work for governmental space agencies, such as NASA or ESA, or for private aerospace companies. Their roles can include piloting spacecraft, performing spacewalks, conducting experiments in microgravity, and participating in international space missions. The term “astronaut” is derived from the Greek words “astro,” meaning star, and “nautes,” meaning sailor, essentially referring to a “sailor of the stars.”
