That should be cosmonaut. We rely on the Russians to get into space.
The space agencies say “one cosmonaut and one astronaut.”
I always liked “cosmonaut” — getting launched into the cosmos.
UK Daily Mail — “Russian cosmonaut Aleksey Ovchinin retained an enviable sang-froid as he realised what was happening after they were rocked violently around in their seats by the force of the booster malfunction. ‘An accident with the booster, 2 minutes, 45 seconds. That was a quick flight. We are tightening our seatbelts.’ he said in a calm voice in a streamed video of the incident.”
I don’t think that’s the language,I’d have been using!
