The arching sky is calling
Spacemen back to their trade.
All hands! Stand by! Free falling!
And the lights below us fade.

Any aspiring space explorers in the audience?  NASA is looking for astronauts - sadly, US citizens only, and out of over 12,000 applicants in 2020, only ten became astronaut candidates: odds of 1 in 1200 against you, even if it was a random selection. But you know, if you don't apply, the odds are zero.
