>mfw you have to be a politically correct SJW liberal c uck to get into the current space industry / astronaut training because you're representing "muhhh humanity"
might get affordable but i would wait atleast 10 000 flights or something, those space crafts seem to blow up frequently
Space travel to where? And to do what? Your question is imprecise.
E.g. Elon Musk attempts to offer trips to Mars for US $500k in around 15 years.
If you have something specific, just ask. I work in the private space industry (and I'm not a liberal cuck).

I actually do this, I made projects for the ESA - EAC with the office I am working.
But consider this: In 50 years, aircraft went from Weisskopf & Orville to Boeing & Douglas, to simplify it.
It was only in 1998 that private space flight was legalized in the US.
NASA has blown countless money on publicity stunts. It was only in the last Apollo mission that they brought an actual scientist along, a geologist.
The Space Shuttle won't I discuss, because it will take too much time.
No, you are a social conservative cuck who gladly gets paid to see if over-edcuated STEM can wipe their butts in 0-G.
People need to adapt their diet according to their environment; your caloric needs on Mars are different to those on Earth, or space.
You also need to be in an exercise regiment so as to not lose the ability to walk in non-zero G conditions.
Maybe not right now, but once we start working with distances more than a light year away communication will get awful slow, so a nutritionist would be needed onboard to attend to the crew.
