> practical to adapt life to space

This is not practical in terms of microgravity environments. You just have to read the space shuttle manual to learn how to correct a broken toilet before you understand how poorly equipped we are to handle this challenge. If you can't fix it you're back to the Apollo style bags. The toilet has a 21 day lifetime anyways. Reading the manual further shows why. Turns out lots of holes between the inside and outside are so terrible you'd rather hold onto your waste than build a convenience. Even so turds at suborbital velocities are a terrifying thought on every level.

Any loose item in the ship is an _immediate_ choking hazard. There's no gravity. Surface tension does strange things. Even to your throat. You have to trust that every person on board is going to reliably capture and contain all debris at all times. God help you if you have to fire the engines for a short period because suddenly there's "gravity" again. You can rotate a space station but you can't go anywhere really.

Medically you can't do any imaging other than weak ultrasound. No X-Rays even. Surgery is effectively impossible without gravity anyways. Not that you'll ever get that close to the effort. It's absurd how brightly we paint this dim picture in our culture and our military style propaganda.

Until we have artificial gravity I personally think we have no business in space as a civilian effort and we're not going to get particularly far from Earth because of it.
