Reply to comment by Customer-Useful in Glass beads on moon’s surface may hold billions of tonnes of water, scientists say | The moon by GeraldKutney

One of the major barriers to space exploration is the high cost to weight ratio of leaving the Earths Gravity well.

If you could base a major component of your lift capability and refueling capability outside earth's gravity our ability to explore just increased exponentially. To do that you need a source of hydrogen and oxygen, for fuel, by a qirk of nature water has both of those things.

I never really thought about the fact that propulsion isn't needed to move when you're in space.

So we need some way to conduct electrolysis on a major scale ON the moon? Solar power or something? I'm no expert but surely you can't use a set amount of fuel to make MORE fuel via electrolysis.

Probably solar, nuclear or a hydrogen fuel cell
