r/worldnews – NASA announces that moon definitely has water in major breakthrough that could allow travel into deep space

It isn’t about water replenishment, it is about mass.

How much fuel is required to launch a spacecraft from Earth versus a body with 84% less gravity? If you can construct and launch spacecraft from Luna, you can avoid a ton of design constraints that limit Earth-origin spacecraft and save on fuel allowing for easier space travel.

Of course, any crews trying to build spacecraft there will need supplies, so the less you need to ship up, the better. If they have a local source of water, that’s tons of material that now doesn’t have to be shipped and could potentially make a moon base cost viable.
