VASIMR Lunar Tug

A VASIMR powered lunar tug can carry three times more payload to the moon then ordinary chemical propulsion. The tug would be launched once and placed in orbit around Earth. It would unfold gigantic solar panels. A payload would then be launched from Earth, including fuel for the tug. The tug would then spiral out towards the moon, in a process taking six months. The cargo lander would then detach and land near the lunar base. The tug would then presumably slingshot around the moon and aerobrake back into Earth orbit, where it could wait for another payload.
