Ah, yes, the mouseover text on that is brilliant, and apt:
"The universe is probably littered with the one-planet graves of cultures which made the sensible economic decision that there's no good reason to go into space--each discovered, studied, and remembered by the ones who made the irrational decision."
Personally, I'm optimistic that there'll be boots on the moon sometime around 2020 (although I suspect they won't have NASA logos on them). Looks like there will be 2-6 moonwalkers left to see that, with a 90% confidence interval...
I too am optimistic. All day I've seen people claiming America's moon landings for all humankind, and then blithely ignoring planned Indian, Japanese and Chinese lunar programmes. It would be a shame to think that people were only excited at the thought of white people going back to the moon.
