A lunar base and mining operation would lower the cost for lunar operations by 70 times and by ten times for high earth orbit. A lunar mining operation would also lower the cost of operations to Mars and the SpaceX plans for a city on Mars. Before, Elon Musk makes a city on Mars using a dozen fleets of one hundred Starships he will build a mining town on the moon.
Hypebeast has rendered a Tesla Cybertruck as a six-wheel lunar rover.
Cybertrucks could be converted into bulldozers and mining machines.
Nextbigfuture has noted that with about 20 lunar missions with SpaceX Starships, SpaceX could build a one gigawatt industrial moon base. This would use solar power and batteries.
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. If SpaceX can build the Moon base and mining operation for about $4-10 billion, then they could easily capture the $2-3 billion in revenue from providing lunar water for space operations.
