"Give someone a fish and you feed them for a day. Train someone in rocket science and they'll be able to create wonders." This is the logic of "useless" expenditures on space programs, and it is not some theoretical claim, but one that has been borne out many times in the US and elsewhere. This ground has been covered so many times in the past fifty years it isn't clear why anyone still believes that investment in space exploration is not a wise way to spend a modest fraction of taxpayer's money.
