"Water is the stuff of life ..."

Not for life, but robots (hydrogen...). Mining will be automated.

Ah1 No people! I don't think so.

Even my non-scientific mind has long expected Moon ice. And Mars too.

But Mercury? I thought she was too close to the Sun.

Fred

It would sure cut the amount of water needing to be transported into orbit then to a base on the moon.

Arei

If we mine the moon will we do it on the dark side so a giant pit mine doesn't ruin the vista?

It would be easier to launch water from the Moon to LEO than the other way around. The initial costs for building infrastructure on the Moon would be earned back soon.
Again, think not having all of our eggs in one big blue basket. Only by some living off Earth will humankind gain some security. Humans are very agile and adjust quickly to new environments. Nothing, maybe not the hearts of stars, is truly out of our reach. We have to make the decision to reach out. It is basic survival.
With this newly found water, the Moon can become a way station to the cosmos, right now.
Lets go.

GeneO

Never mind my question about Mercury. Just found a site that explains the polar region is minus 160 degrees F. Weird considering that at their equator it gets up to plus 800 degrees F.

Dark side? There is no dark side, so I suspect you meant to say the far side.

Lars

I would like to think that one of my grandchildren would be able to at the end of a hard day in the mines, to sit down and have a moonito and gaze up at the beautiful planet above.

Arei

Dark, far, unseen are synonyms for the side of the moon not locked facing us but that is besides my point. When we do colonize the moon will we protect its beauty or will it become polluted too?

ISL

IT would be even easier to get water to LEO from an asteroid - as long as you have the time and use a solar powered electric gun for propulsion.

ambrit

Agreed if one has a long enough time frame. As with the Sunjammer discussion from a few days ago, several fairly cheap methods of obtaining water from places other than the Earth are available. I favour the Moon as source for near Earth applications because it can be obtained fairly quickly, and cheaper than lifting it from out of the Earth's gravity well.
For 'slow boat' class cargoes, a sunjammer would be optimal. For human cargoes, a Dumbo or Orion are presently feasible. As an aside, for all those worried about solar flux being an existential threat to human travel around our solar system, well, the shielding needed to protect the human cargo of a vessel from the atomics of the drive would also be adequate to shield those humans in transit from solar flares, etc.
Feasibility is the name of the game here.

Fred

ambrit,

"Feasibility is the name of the game here." Yes but also influenced by just how much money is invested for how long before an actual return is made.

ambrit

Fred;
Yes as to present modes of thought about this sort of project. However, there are some projects that are conceived of differently, such as the Egyptian Pyramids, Stonehenge, the Gothic Churches, etc.
Reduce or eliminate the purely pecuniary motives of such a project, admitting that the gathering and organization of resources is a sub-task, and amazing things have been, and will be possible. As a side observation, I'll say that faith, of, really, anything, does indeed move mountains. If those mountains just happen to be in the sky, so much the better.
When I was young, I truly believed, almost as an article of faith, that mankind would already be exploring the solar system in person by this time. Alas, I might not live to see it, but I still have that hope and faith.

Barbara Ann

Lars you have poetry in your soul. I would hope that moonito would be made from locally grown limes and mint.
