“It could look something like this: in partnership with the US government, a private company — let’s call it Regolift MegaCorp — sends fuel-cell powered, tele-operated robots to the lunar poles to mine their icy regolith. There, they separate the ice from the soil, and electrolyze the ice to make hydrogen and oxygen, which when condensed into liquid form (LOX, LH2 respectively), can be used as propellent. It’s potentially most valuable (useful) in orbit, so Regolift MegaCorp launches the propellant off the moon to an orbital outpost where clients can access it.” ~ learn more
