If we're saving it for later (but for some reason don't want it on Earth) we should just launch it into orbit around the Earth. Why waste the fuel to send it outside Earth orbit just to need it back later. Even if we wanted to use the materials somewhere else in the solar system, just park it in orbit around Earth until its time to move it.
