Philip Metzger has a study of mining water on the moon. If water is mined on the moon then it could save satellite missions to geosynchronous orbits about $100 million.
Currently it costs over $100 million for the extra stage to move from low earth orbit or the use of ion thrusters that take one year to move the satellite. The delayed operation is close to the cost of the boost stage.
Water can be mined on the Moon, delivered to a gas station, sold to operators of the space tug, who will then boost the satellite to its final orbit for much less than $100 million per spacecraft.
Here is the link to the 189-page water mining on the moon report.
A wide range of potential customers for the hydrogen and oxygen products has been identified. They can be used to fuel reusable landers going back and forth between the lunar surface and lunar orbit. They can make travel to Mars less expensive if the interplanetary vehicle can be refueled in cislunar space prior to departure. Operations closer to Earth can also benefit from this new, inexpensive source of propellant. Refueling in Low Earth Orbit can greatly improve the size, type, and cost of missions to Geosynchronous Earth Orbit and beyond. This study has identified a near term annual demand of 450 metric tons of lunar derived propellant equating to 2,450 metric tons of processed lunar water generating $2.4 billion of revenue annually.

i dont know why the US is so stupid not to invest more in a space economy. We'd be rich beyond all imagination an be able to pay this damn debt.
Also where the hell is Defense/military tag and technology tag?
