  1. Question: Has any significant research been done on the effects of 1/3 normal gravity on the human body over prolonged exposure? If living for an extended period in 1/3 normal gravity causes significant serious damage to the human body, then Mars and the Moon are essentially worthless for human colonization. Before we spend tons of money trying to colonize Mars or the Moon , we should now the answer to this. Research on mice on this issue could be done on this issue on the ISS at very low costs in terms of launch cots, space on the ISS, and astronaut time. When will this be done?

  2. Lensflare Deviant Mice! Take a rotating habitat 2 m in diameter up to the international space station put by cement and rotated at about 20 rpm. That will give you an apparent gravity for the base of about 1/3 normal gravity or something just about equal to Mars gravity. Keep the mice there for as long as you want (they don’t have a Union) then bring them back and see what kind of effects of happened or not happened on their metabolism. Cheap, quick to do, and it would certainly give us some significant data. Certainly, It wouldn’t be data on people but it would give us some indications of what we might see in people. Right now, as far as I know the international space station is the only place that we could really do this kind of testing quickly and cheaply. As far as I know though, no one is doing it. Why not? Wasn’t the idea behind the international space station to enable us to do experiments exactly like this?
