Uhh… I’ve never heard a single astronaut say “I wish I’d spent less time in orbit”.
Most astronauts sign up because they want to go to space, but then they end up only spending 1-6 months in space over the entirety of their career.
Imagine you wanted to be a chef, so you went to the finest culinary schools and then eventually for a job at an acclaimed restaurant. But then you had to just peel potatoes for years, before finally they let you be a provisional chef for a week and you actually got to use the skills you trained for, but still knowing that they’ll put you back on boring prep duty at the end of the week… But then at the end of the week the head chef gets sick and he’s out for the whole month! How would that feel?
Remember, this isn’t a vacation, this is their career. This is what they want to do. And these people have the most impressive resumes you’ve ever seen in your life, no joke, reading one is intimidating. They could do just about anything they want, and they choose this.
