If we can not cost effectively mine or inhabit our artic regions or even travel there to supply/support the populations should we be going to space?
If we can not safely mine the ocean trenches for rare earth metals and potash, should we be going into space.
We we can safety inhabit the deepest parts of the oceans for travel, farming, and mining then we can talk about space exploration.
And yes the private sector may be able to do this better.
The most important thing is that the private sector will pay for the exploration/tourism and not the taxpayers.
