This is why the obvious solution is to compartmentalize the artificial gravity habitats:
You have a single, exterior shell, which does NOT rotate. This allows spacewalks without all those nasty issues.
Inside this shell, you have several cylendrical habitats that counter-rotate. The combined rotational force is a net zero, which is why the exterior shell does not rotate.
(Simplest configuration-- One long cylendar, with two cylendars inside. One of these rotates clockwise, the other counter clockwise. The long axis of all cylendars is conserved.)
This would allow you to use the gravitational habitats as reaction control wheels. They could also be spun down for easy maintenance-- Being INSIDE the vehicle's outer shell, the whole interstitial space between the habitat and the outer hull could be pressurized. Maintenance to the moving parts would be radically less difficult, and lost tools would only happen on exterior hull maintenance. Again, exterior hull DOES NOT SPIN.
The reason we dont design space vessels this way is very blunt: It costs a WHOLE FUCKING LOT OF MONEY to orbit just a few pounds of weight. Proper design is easy--- Logistics of lofting something that works, even halfassed, is NOT.
This argument isnt about long term space missions.
This argument is really about why we arent using the moon for staging our orbiting vehicle construction.
If we used the moon this way, we could AFFORD to build CORRECT space vehicles that DO supply sufficient shielding.
We dont, because that means having a real, self-sustaining colony on the moon, which means having joe sixpack in space, and all the trappings that go with it. (Space pubs/bars, and space hookers. No society in the history of mankind has been without them. The moon would be no different.) This is VERY unattractive to high-minded politicians and researchers. NOBODY wants to be the guy who puts space whores on the moon.
However, private industry has no such qualms. They will happily put "Candy" on the moon, to do her low G poledance routine, as long as she can pay the ficket price for her flight.
We will get there eventually; but really, we should have been more aggressive about getting things set up and running on the moon.
Politically, government has to contend with things like "Making sure single mothers and orphans get subsidized health and food services"-- Again, private industry has no such requirement.
It wont be pretty, but at least it will eventually get there. Just dont expect star trek.
Instead, the grim spectre is "The company store". (I wouldnt be surprised if the early privatized space agencies actually negotiate a fee for candy's services, and actually ship her up themselves!) The companies that fund and build the colony sites up there are going to have literal material monopolies on everything from power, to water, to air, to food. And in a potentially unregulatable environment. Nasty business.
But again-- we WILL eventually get there, but the end result wont be roses and sunshine. Government is not capable of the sustained attention focus in the face of voter interests--- and private industry has no real humanitarian interests.
Private indsutry will go anywhere and do anything that people are willing to pay money for, and will tailor its actions to maximize its financial bottom line. -- That's a two edged sword of truth. (If there's a market, and profit to be made in sacrificing babies to Satan, they would cheerfully sacrifice as many babies as possible to get that money given half the chance. Private industry is NOT a moral actor.)
There is a vast and untapped market in space. The need for orbiting telecom, and improved service and uptime of same, is only getting greater by the minute. The first group to succeed in getting a viable colony on the moon to provide manufacturing, orbiting, and service agreements for terrestrial satellites (based from the moon, where such service can be cheap) will have a veritable monopoly, PLANET WIDE. The financial forcast for that is astounding. Properly managed, that opens the door to monopolized interplanetary flights as well. People who dont see this do not see the big picture. Private industry however DOES. That's why bigtime venture captialists like Musk and pals are all over it like flies on shit.
So, again-- it WILL eventually happen, because that's how you win in that game, and given who is playing now.
And again, it wont be pretty.
Until that time however, we are limited in what we can launch, financially. Which is why we have spacecraft that dont simulate gravity, and are literally made from metal foil, like potato chip bags are made of--- which just so happens to be why most astronaughts develop highly conspicuous occupationally derived health problems.
