Just how wacky can Republican candidates get?  Newt Gingrich has called for a huge ramping up of US space exploration, including a permanent Moon settlement by the end of his second term as President.  I suppose that's possible if the American people get so pissed off at him they load him into a rocket for a one way trip to the Moon.  Or his second term as President is 50 years after the first.  This also brings to mind the old saw about amateurs and logistics.
