We got to watch men walk on the moon and that's enough for one generation. It had better be, because we're not going to get anything more in our time. I'd say we're about at the same stage in space as the Newfoundland Norse were in North America. It was centuries after that before the Basques figured out how to make the whaling grounds and fisheries pay, not to mention Coronado discovering Kansas. There aren't going to be any Mexicos or Perus for us to conquer, which may be just as well. Certainly George W. is no Prince Henry the Navigator.
