David Frum : Newt Gingrich has attracted some ridicule for his proposal for a moon colony . Or , to put it less grandly , for its immense possibilities . He says he is n't alone in wanting to spend money on unnecessary manned missions . Frum says science can be done more effectively , cheaply in space with unmanned missions . He says Gingrich 's proposal is n't a plan for the future , but rather nostalgia .
