Great. I always wondered about Coriolis Forces on those stations? Are those a big deal? Will people feel them?

  The short answer is "it depends", but at 1-2 rpm they will be not a big deal. The long answer would be a proper reference, such as this one: https://www.researchgate.net/publication/305768041_Artificial_Gravity_in_Theory_and_Practice https://www.researchgate.net/publication/305768041_Artificia...

Since you know a lot about this; Does the human body really need 1G of gravity to avoid the bad effects of long term weightlessness? Would it be sufficient with say 0.5G or 0.25G? I assume it would reduce the radius and speed requirement of a rotating space station quite considerably.

  The most accurate answer is "we don't know", unfortunately. My personal concern is that 0.38g of Mars environment would be not enough for long-term survival and procreation of humans there.

I consider space stations to be far more realistic than Mars colonisation, which to me seems like a destination that no-one would actually want to go to when they realise that Mars has far lower gravity and far less sunlight than Earth - not to mention the hazards Martian dust. Even if we manage to terraform Mars, it'll still be a tough place to live. Space stations however - you can make them however you want. I've seen concepts of rotating habits that are so massive that there's no "roof" on the inner-side, only walls to stop the atmosphere leaking out. No idea if that would actually work or not, but it looked cool.
