NASA scientists are intensifying their investigation into a vision disorder that affects 70% of astronauts on long-duration space missions, as new research reveals the condition poses mounting risks for future Mars exploration 1 2. Space- Associated Neuro-Ocular Syndrome (SANS) causes crew members to experience blurred reading vision, swollen optic discs, and flattened eyeballs that can persist for years after returning to Earth

I've seen a video (maybe it was Smarter Every Day?) about a research team experimenting with the effects and acclimation potential of small-radius coriolis stations. From what I remember we can get used to the centrifugal force well enough, even though experiencing coriolis forces across the length of your body is certainly an unusual situation.

Profitability is a huge problem regardless though. The ISS is getting destroyed by the end of the decade, and no replacement is seriously planned. The ISS was born in a geopolitical context of unprecedented international cooperation in the '90s, and that era is long gone. Unless China, the EU or US (lmao) wants to finance an ISS replacement all on their lonesome, not much will happen there for the foreseeable future. There's not a whole lot "because we can" budgets going around these days.
