re: High Frontier ?
It takes 8 fewer steps to get to the same link.
I remember the public agreeing with sticking to low Earth orbit, with the Shuttle and leave the Moon alone.
Now, some complain astronauts go nowhere but arounf and around the planet....
I remember O'Neill defending the concept of an artificial One G station in space.
Then it became the 0 G space station
Then it's a world again: the Moon or especially Mars (forget the gravity difference)...
How quickly space nuts change their minds.
Meaning how weak those arguments are, in reality.
