The only experiments that we've done are earth based and involve horizontal acceleration. Sounds like we need to do some real life space tests! Maybe we can get something going with a central weight and a tether so the test pod can rotate around it at high speeds. Also, I recall there being studies into changing how the inner ear is reacting to movement. Maybe someday space goers will have implants to calm the inner ear against coriolis.

An inflatable habitat could hold a small-ish centrifuge enough for some tests and to provide some semblance of gravity for sleep and exercise. If it gets really bad, the centrifuge can be dismantled and its remains used as divisions for what would be a very large empty space. Tethering two Dragons together would be complicated and maybe require an EVA to attach the tether. The trunk remains attached during a launch abort, so it can survive 1g without flying away (the Dragons will need it for deorbit after the experiment). I'm also guessing they'd need some redesign, because you don't want to mess with the parachute fixation points and, even if you did, the "floor" of the capsule should, for this exercise, be perpendicular to the acceleration. In short, I guess we need sci-fi grade engines that can pull 1g for weeks at a time.

I think you’d want to do experiments with two equally weighted pods on each end of a “salt and pepper” (see https://youtu.be/U-a_gtcftZg https://youtu.be/U-a_gtcftZg) type setup. I hope to see tests in space as well. There’s likely some sweet spot that strikes a good balance between mitigating sickness, providing enough gravity to be useful, and being a reasonable size, and I think testing different configurations with a minimal rig where you change the diameter and rotational speed is the only way to discover it. I might be wrong though. There might be compelling evidence there is no such sweet spot and that looking for one would be a waste of time.
