-The impact of zero gravity on human health has been studied for decades on Russian and US space stations. We know the human body needs gravity to stay healthy, but nobody knows how much gravity is needed.  We need research on the health impact of long term living in partial gravity environments, especially the 0.15G on the Moon and 0.4G on Mars.
+The impact of zero gravity on human health has been studied for decades on Russian and US space stations. We know the human body needs gravity to stay healthy, but nobody knows how much gravity is needed.  We need research on the health impact of long term living in partial gravity environments, especially the 0.17G on the Moon and 0.4G on Mars.
 One way to test the long term impact of lower gravity on the human body would be to set up stations on the Moon and Mars and have people live there for a long time.  However, this is very expensive and could be dangerous - sending people to another planetary body without the right exercise equipment could seriously impact their health.

 * Astronauts could be brought back to earth quickly if health problems come up.
 * The gravity on a space station can be adjusted, so various levels of gravity can be tested in one laboratory.
-* It may be possible to assemble the space station from available components and launch it with "commodity" launchers.
+* As usual the equipment would require expensive launch on rockets to orbit, but the  cost of design and fabrication for things launched into orbit is usually a number of times greater than the launch costs .
-The impact of the last item cannot be underestimated.  If an experiment like this is too expensive, it will not be done.  However, if it can be designed "on the cheap", it may be possible to get the funding required to carry out the experiment.  Using off the shelf components as much as possible could greatly reduce development and launch costs.
+The impact of the last item cannot be underestimated because the lowest estimate that could be made is likely to be greater than the impact of the experiment as a whole.  If an experiment like this is too expensive, it will not be done.  However, if it can be designed privately at no cost whatever to the government and offered freely to NASA, it is still unlikely to be done.  Using off the shelf components as much as possible could reduce development costs but is likely to increase launch costs by resulting in a heavier experiment package.

-By using off the shelf components, the budget for infrastructure development can be kept to a minimum.  Getting maximum science return per dollar is the only thing that can make this kind of experiment feasible.
+There is no need to have this experiment done before establishing a robotic colony on Luna.  Once robotic industry is established one g gravity can be provided if it is found to be necessary.  A centrifuge can be constructed on the Moon out of lunar materials to provide for the health of personnel that maintain the base.

-In order to simulate partial gravity, the space station will need to rotate.  To make that happen, either the space station needs to be of a sufficiently large diameter or consist of several components mounted in a "dumbell" arrangement.
+A current idea is to modify a Bigelow inflatable space station by assembling a floor from smaller rigid components inside the inflatable walls.  See [[Partial G Space Station]].

 Testing the impact of partial gravity on human health in low earth orbit has several advantages:
 * Astronauts could be brought back to earth quickly if health problems come up.
