Now, four astronauts is not a permanent colony on the moon. To have a permanent colony, you would have to manufacture housing, most likely underground, or at least under significant shielding, since there is no atmosphere and no magnetic field to shield against the harmful effects of cosmic rays for an extended period. Not to mention the need to build facilities for waste recycling, plus food storage and preparation. That is, unless we continually provide food and other provisions for pilgrims from Earth, creating a non-self-sustaining colony. But Gingrich has already made it quite clear, in his attacks on President Obama, that he would not like to be remembered for championing any such sort of government-sponsored food program.
