What is the literal meaning of Cosmonaut derived from its Greek components?

Answer

Universe sailor

The designation Cosmonaut originates from Greek roots combined similarly to 'Astronaut'. The first part, 'kosmos', means 'universe'. The second part, 'nautēs', means 'sailor'. Thus, the term literally translates to 'universe sailor'. This linguistic choice reflects the ambition of the Soviet program to explore the entirety of the cosmos. This meaning is functionally similar to the meaning of Astronaut ('star sailor'), but the difference in the prefix highlights the distinct national framing applied to space exploration efforts during the Cold War era.
