Astronaut vs. Cosmonaut: Know the Difference
By Shumaila Saeed || Published on January 28, 2024
An astronaut is a space traveler from any country except Russia, trained for space exploration, while a cosmonaut is specifically a Russian space traveler, reflecting the different space programs and terminologies of the USA and Russia.
Key Differences
The term astronaut is derived from the Greek words "astron" (star) and "nautes" (sailor), used primarily by NASA and other space agencies. Cosmonaut, on the other hand, comes from the Greek "kosmos" (universe) and "nautes", and is the term used by the Russian space agency.
