Some of the savings from defunding the ISS would feed into NASA's return to the moon, chiefly a new lunar robotic exploration program as well as a «Deep Space Gateway» in lunar orbit that would serve as a staging ground for operations on the surface.

One idea would be to reduce the crew size from four to the three of the Apollo days, with the idea that on the Outpost - type fortnight - or - more span expeditions, we'll be able to send the whole crew down to the surface, leaving the Orion (or whichever) orbiter craft, untended in low lunar orbit, to be reached by the crew later.
