Yes.

By the way, I just discovered another problem with 1/3rd or 1/6th g:
http://en.wikipedia.org/wiki/Artificial_gravity

"Astronauts were exposed to artificial gravity levels ranging from 0.2 to 1 g for a few minutes during several spaceflight missions, using linear sleds or rotating chairs. They did not perceive any changes in their spatial orientation when the g level was lower than 0.5 g at the inner ear level, where the sensory receptors for gravity perception are located.[3]"

Elon Musk might be in for an unpleasant surprise when he moves to Mars.

Maybe I'm misreading this, but it sounds like they're saying if I was sitting in 40% gravity, and closed my eyes, I would not be able to tell up from down. That sure doesn't sound right.

I would agree that Mars advocates strongly insist 1/3 G is OK because they have to, not because there's good data to point to.

Waited to see the response of others to what could be misapplied research but didn't see any. The statement that inner ear perceptions of up and down were lost at 0.5 g seems correct for the test but wrong when you can properly stand or sit for a while.

Does the Apollo astronauts make statements about not knowing up from down in 0.165 g?

That was what made me skeptical. Several of the Apollo astronauts slept in hammocks in the LM. It seemed to me if that figure was right, then we would have heard stories of them saying they lost all perception of up and down when they closed their eyes to sleep.

I suspect either the number cited is wrong, or we're misinterpreting their phrasing.

This was under artificial gravity, and so would have involved a lot of whirling about with short radii of rotation, and thus likely to cause all sorts of inner-ear confusion.

I've never heard any such, but I expect the Moon Hoax people to hook onto this fast.
