when are they going to make a wheel shaped spacecraft so they can artificially create at least SOME gravity Likely right after someone invents a frictionless material for the huge bearings that will be needed at the hub of such a "wheel".
To: Mr. K
If you ask me, there should going into deep space without one. Traveling that far away, they should be bringing their own full size space station along to live in.
But there are better and brighter people than myself in charge of these things.

There’s always magnetic bearings if that is your concern. I think it more likely engineering issues of being able to maneuver something which is a giant gyroscope and doesn’t want to turn.

why make the hub stationary?
let the whole thing rotate

Would counter rotating wheels work?
I think that’s how some designs of helicopters fly without a tail rotor?

when re they going to make a wheel shaped spacecraft so they can artifically create at least SOME gravity. I have often wondered the same thing. In fact, Hollyweird has depicted this in several movies. Considering all that has to be done is to build a Tube and spin it rapidly, it seems simple. The craft would need to be assembled in space and that might be challenging.
I expect the problems are: for some components like navigation, experiments and communications, there needs to be a stable platform (not rotating).There may be a need to have a component of the craft that is not rotating. Anything attached will create friction and thereby rob energy and create wear on components. It's a failure point that is difficult to test. Also, maintaining the balance in a gyroscopic vessel would be critical for the craft to maintain a constant trajectory without regular correction (more energy consumption).

Likely right after someone invents a frictionless material for the huge bearings that will be needed at the hub of such a "wheel". Are you assuming the need for non rotatating center core? What need is there for that? Given a slow rim speed, a fixed central core would barely register as moving, no?

How about some bungee cords and a couple of eyebolts welded to the interior of the craft? It may not be Gold’s Gym, but the resistance should keep you from turning into a gersh on the trip. You can work arms, legs, back, even abs to some degree. Add more (or stiffer) cords to increase the resistance.
You can even call them Space Bungees and charge NASA $100,000 apiece for them.

Has to have a cutesy name before NASA will buy it.
Some cutesy anagram, like the Deepspace Unified Preventive Exercise Module or “DUPEM”

Question: Does the gyroscopic effect work in space?

It has to be a fairly large diameter to be practical.

This is the device they're putting on the IST, the "MED-2". Its launch weight is 65 lbs. or about one half that of a female astronaut. And God only knows what it costs. The ROCKY device looks like it works on the same principle but its housed in a black cube. For the life of me I don't see where either of them couldn't be replaced by a set of elastic tubes, handles, and a few securing points on a bulkhead. Cost: a few dollars. Launch weight: almost nothing.

Yes. It is an effect of momentum, not gravity.
