You do realise that we don't need to use a ship to "land" with the he3 right? We only neef a ship that can transport it from moon to earth and just drop it in athmosphere. We just need a box big enough and with parachutes. Oh and launching from the moon into space would be tricky, and a goog enough crew to catch the cargo hold orbiting moon. But i still think we need bigger space ships being able to make the run moon-earth. But if simehow we manage go get some technology to be able to build rockets on the moon that would be a looooot easyer since we won't be needing that much fuel to launch cargo in space, even shuttles. Sorry if some words didn't came up right, i am on my phone and typeing a comment is hard as hell.
