Given the name I was under the impression that this would be a rotating module to create artificial gravity, but it seems instead it is just a large capsule.
> However, there are no current practical outer space applications of artificial gravity for humans due to concerns about the size and cost of a spacecraft necessary to produce a useful centripetal force ... Scientists are concerned about the effect of such a system on the inner ear of the occupants.

Looks like visitors to space will have to keep dealing with zero-gee for the foreseeable future.
I would love to see a pair of Starships hooked together with a sturdy cable a couple of dozen meters long and then spun around each other to simulate gravity.
An extreme example to illustrate would be a small module with a radius that equals the height of a stationary standing occupant. Their feet would feel normal, but their head would still be "weightless" and getting very dizzy. Actually moving is even worse: Not only would the weights of objects vary depending on their "height", but "falling" objects would seem to have curved paths, so your sometimes-heavy feet would keep "missing" the place you intended to put them down.
If you split the module into two with a tether or girder in-between (or replace one half with a dumb counterweight) that reduces the Coriolis effect... but now you've got something that alternately sweeps through space in a kinda-dangerous way, and it becomes harder to safely enter or exit.
TLDR: Spinning becomes useful on scales we aren't ready to do yet.
