Manned space flight is such folly. We need to divide the money we spend on it and use half to bolster the unmanned probes that have brought us so much knowledge, and spend the other half on basic physics. If we are ever going to do space travel the way most people imagine it, we are going to need warp drive, artificial gravity, “shields” to ward off radiation and matter traveling to relativistic speeds, and all the rest of the sci-fi stuff. We have no idea how to do any of that, so we better start now to figure that out.
We have been fortunate up to this point because space tragedies happened and were over with immediately. Wait until we have someone orbiting Mars with no way to leave and we sit here for months watching the CNN Mars Death Clock while their oxygen and other supplies slowly run out. I think we really need to avoid that.
How are we going to learn how to do what you propose without keeping humans in space?
That made me chuckle.
As someone who shouldn't have once told me...
"You like science fiction, right? Take what you think we might have, add 100 years, and you are getting close."
