[ExI] Why no space colonies or lunar bases? was Mooon.

[John Grigg]

Keith, I would think the answer is to let technology mature to the point
where we can built an effective space elevator, circa 2030 or 2040.  And
then the price of going into space plunges downward to I believe around $100
a pound!

Our competition with China will get us there...
