The ISS has supported a crewed presence in space for twenty years now and while parts have been added over time, key original components are 20+ years old.

Crewed presence is usually limited to a half-year at a time, though there have been a few stays of about a year. Despite an aggressive exercise regiment and other countermeasures, astronauts experience health problems like bone loss and vision issues due to extended exposure to microgravity.

I was wondering; are there any active proposals for a future crewed space station (probably commercial) to use artificial gravity?

  • $\begingroup$ Do you mean proposals that are planning to be built, or just proposals in general? $\endgroup$

    $\begingroup$ It's certainly an important question. Our knowledge of how gravity affects living organisms is basically limited to 0 g, 1 g and (via centrifuges) higher gravity levels. We really don't know what happens in the range between 0 and 1, yet this is the range in which many planets and moons fall. $\endgroup$

  • $\begingroup$ Nautilus-X was one proposal for a rotating wheel space station, but it didn't make it past the concept stage. The Space Islands Group also proposed rotating wheel space stations, but it also didn't get past the concept stage and they were too large to be realistic in the near future. (Also the ISS Centrifuge Accommodations Module was proposed for specimens smaller than 0.62 m, but it was cancelled.) $\endgroup$

  • $\begingroup$ Very good question. I'm one of those who believe human exploration of the solar system beyond the Moon will probably require artificial gravity. Without it missions to Mars may be too risky. So I'm puzzled no attempt to make a rotating space wheel is even planned. Perhaps Elon will get around to it if he discovers having astronauts weightless for >6 months will compromise their performance on Mars and impose excessive risk. $\endgroup$

Note: Engineering Judgement Applied when figuring what active proposal means

No, there are no active proposals for a future crewed space station to use artificial gravity.

The only planned space station which has a realistic chance of being built close to its announced schedule is the 'Chinese large modular space station'

It is a free-fall design.

You can peruse a list of planned space stations here. All are free-fall designs.

Roskosmos has plans to build a Mir-type orbital station (without artificial gravity) using new ISS modules.

Roskosmos after 50 years of work with orbital stations in Earth orbit plans to build a small lunar orbital station.

    $\begingroup$ Just to inject a dose of skepticism: Roscosmos isn't doing so hot and has a history of making big plans and promises but then never executing. I wouldn't be surprised if the agency's human spaceflight program does not survive past the planned shutdown of the ISS. $\endgroup$

    $\begingroup$ @Dragongeek The published plans are not a work plan. This is an attempt to get funding for several years in advance.The real picture can be seen in the economic courts in which Roscosmos participates. $\endgroup$
