Who knows what happen with astronaut's health after 500 day in zero gravity ?
No one, just guessing...

All of those are less than 500 days. So the answer is no one has done the research.

True. After 500 days maybe the adaptation is complete and the potential for negative health risks completely disappears. This is impossible to figure out theoretically. It has to be done in order to find out. But it should of course not be done Dr. Mengele style, but for a purpose that makes the risk of discovering the unknown worthwhile. Like spending the time on the Moon or Mars or Mars' moons. Not spending it in a nowhere Gateway.

So a space-station is like Auschwitz?

A space station that "tries out" how long humans can survive in it, really is! That's the profit from torturing people. It is completely different to send a crew out on a dangerous exploration mission that would return great discoveries if it works. The maximum potential loss is the same in both cases. The difference is that one of the cases has a possible upside. The other does not. It is a failure of design, and of humanity, to pick the latter.

Those are just single stays. For cumulative time in space, there are currently 19 people over 500 days (soon to be 20 with Peggy Whitson becoming the first woman to reach that mark), the current record holder is Gennady Padalka, who has spent 878 days in space.

That's a Mars back and forth trip time.
Did that make Gennady Padalka lame, blind and mad? Because that is what the space hypochondriacs claim that he must be.

Speaking as someone who has studied such "space hypochondriacs" issues formally, including the research at CERN on human models, and also active studies by SC from Mercury to past Pluto, I can tell you that not a one of them when asked would travel to Mars.

I knew someone would bring this up.  ::)

The question about adverse medical effects is continous time in less than Earth gravity. Obviously, cumulative time includes long periods on Earth between missions giving the body a chance to recover.

We only have data for Earth and microgravity with stays of less than 500 days. No data on lunar or Mars gravity.
