>>>Valery Polyakov spent 437 days on Mir. So we have proof positive that a
duty stay of 437 days followed by return to Earth is acceptable. I
speculate that that could be stretched to a yet even longer period of time.
Let's suppose that a duty stay of two years is acceptable. How necessary
is rotation?>>>

In that case, for manufacturing processes that require gravity, it maybe
easier to design rotating machines rather than a rotating manufacturing
facility. The construction of the facility would be simpler if gravity were
eliminated.
