Re: A never-ending study on how to mess up humans...
"A rotating space vehicle would have to have a large enough radius to generate 1g (or even half a g, that would probably do)"
And that's a fundamental question right there that needs answering eventually. Just how much gravity does the human body need so as not to degrade more than usual over a the months or year(s) of a mission? Say they make it to Mars and find that a long stay in 1/3rd G is bad for them too?
Maybe sometime soon we will see a couple of large Bigelows joined by a tether or even a tube people can get up and down with a docking module in the centre point. (why am I hearing The Blue Danube Waltz in my head?)
