I didn’t see presented (despite the title) any reason why we need to get back to the moon. I understand that ice means water means O2 and H2. However, I would bet that cryos will much much cheaper launched from Earth than made on the moon for a long long time to come.

In fact the only way this makes sense is if launch costs come down and if launch costs come down then Earth originated propellant will be even cheaper even faster. I try, but I can’t make the economics of the ice mining idea work out favorably. Go to the moon sure but maybe don’t use the ice mining argument which (unless someone can educate me?) is as wrong as shuttle being low cost.
