Either that or we'll have to wait until a new propulsion system is developed for spacecraft where the fuel weighs (on edit: masses) a whole lot less for the amount of thrust it provides. Some (many?) qualified crew will likely still be willing to go, though, just to be first. When will or should it be? I don't know.
