At 4 rpm the first settlements are only about 100 m diameter.An interesting (and probably open) question is whether you couldpre-train for this economically on Earth Funny you should ask. There is a project at NASA ames that, for many years, has been spinning people and training them to control their physiological response via feedback and guided imagery (sorry, not VR). It is highly effective. It has also been used to prevent space sickness and outperforms drugs.using virtual reality. Isuspect that could work; the problem (mismatch between visual andvestibular inputs) is pretty much the same.This could be especially important for orbital hotels; you don't wantyour fabulously expensive week's vacation spoiled by two days of nausea..Yes! BTW: the technique developed at NASA ames is available for commercial development.So it might be well worth training for a few hours a day for, say, aI think they use around 6 short sessions spread out over a few weeks.week before your trip, in VR.Best,- Joe
