The moon may be the best place to transport rocket fuel

When astronauts return to the moon in the next few years, the plan is to have them stay for good while establishing a permanent outpost on Earth's nearest celestial neighbor. Like all space missions, a lunar outpost will require fuel for long-term sustainability, but would it be better to mine fuel on the moon or get fuel resupply from the Earth? This is what a team of researchers led by Bocconi University in Italy hope to address as they addressed the best option in terms of deriving fuel from either the Earth or the moon.
