"You can use the existing infrastructure and be back on the moon in 5 to 10 years with a modest investment. You don't have to double the NASA budget," said Paul Spudis, a planetary scientist at the Johns Hopkins University Applied Physics Laboratory in Baltimore, Maryland. *** Reuters
Ok, we have the expendables for the tonnage and the shuttle for the men.
Oops, scratch the shuttle for now. What happens when we are down to two? One? None? A "permananent" moon base really needs a permanent transportation system, and our only manned system is looking real marginal. All the plans to replace our manned system are based on the space station being all we ever do.
Looking at our expendables, I have a hard time imagining that such a modest increase in funding would cover even that end of things.
