What are they expecting to be different about samples from the moon's far side to those previously collected?

I do not know for a fact, but I wouldn't think there is a single chance in hell that living in an environment with 1/6th of the gravity we've got on earth would not cause long term effects in your health, specially to the bones and muscle.
Probably fine .. as long as you don't come home.

Different bragging rights.

#14The international moon base plan is fascinating. https://en.wikipedia.org/wiki/International_Lunar_Research_S... (nuclear power plans by Russia not so much) Is there enough gravity on the moon to prevent the long-term health problems from the space station like bone, muscle and vision loss?
> nuclear power plans by Russia not so much Why? Any lunar base without nuclear power plans is not a serious effort.
Maybe you could use helium or liquid sodium metal as the primary coolant, but then you still need to generate electricty via secondary water coolant loop that runs a steam-powered turbine. Really not plausible on the moon.

I often wondered, how do you deal with all the waste heat from a fission power reactor, in a vacuum? Giant radiators? edit: fixed typo, derp. fusion=fission

Also changes eye shape over time, causing vision issues, etc.. Longer you're up there the more starts to go wrong. We were built to fight off gravity. I think its worth considering that it may be fundamentally impossible for humans to reproduce/gestate babies/live entire lifetimes/generations in low gravity conditions.
If you did have viable babies in low (not zero) gravity situations though, would you in fact be starting a new species.

The reason you seek to explore what you don't know is because you don't know what you don't know. In general I don't think people really appreciate how ridiculously little we know about everything outside of our planet. Like for instance it was only in 2013 (!!!) that it was discovered that Mars' soil is relatively 'moist', about 2% water by mass. And that's just the topsoil layer - it's suggestive that below the sur…

Perhaps? Any reason that sounds silly to you?
I also meant to write fission in my original question, not fusion.
