A cosmonaut is a Russian astronaut trained to travel and work in space. The term specifically refers to individuals sent into space by the Russian space program. Cosmonauts undergo rigorous training in various fields such as science, engineering, and survival skills to prepare for missions aboard spacecraft. They conduct experiments, perform repairs, and often live aboard space stations, like the International Space Station (ISS), contributing to our understanding of space and conducting research that benefits life on Earth. The word "cosmonaut" combines "cosmos," meaning universe, and "naut," meaning sailor, indicating a sailor of the universe.
