There is a big difference between saying something is possible and saying something is easy. I don't think it is easy to build a moon colony. On the other hand, I do not see any scientific or engineering reason why it is not possible. We have already proven we can land on the moon and that we can build space colonies (i.e. ISS). Sure there are hurdles I have not considered, but that just makes it hard not impossible.


Given that we've not been able to create a self-contained biosphere on Earth, the prospect for long-term environmental support on the Moon seems low.

The IIS gets regular resupplies to keep its environmental support systems operational and habitable.


There's no requirement that a lunar colony be self-sustaining in order to qualify as a lunar colony.


There's no requirement

Cost per kg from Earth to Lunar surface argue otherwise.

A multi-national consortium can barely manage to sustain operations of a 6 man crew in low-Earth orbit.


1. Not sure that is a requirement.

2. I bet we could figure it out. Again don't see any reason why it is not possible. Very little research has gone into that particular problem which I think is the main reason it has not been done.
