And @NASAWatch"Golden Spike" commercial lunar exploration company includes Wayne Hale, Jerry Griffin, Alan SternYou've heard of them!
In United States history, the Transcontinental Railroad was officially completed in 1869. The event was marked by driving a golden spike at the location where the Union Pacific and Central Pacific railroads met. The location? Promontory, Utah. We've heard of that location before. Aren't big things made there. In segments. By a little company called ... ATK? Did someone mention use of "existing or soon to be existing launch vehicles" that cannot die?
OK, I just asked Trina, who is the PR wiz at ATK propulsion, and she has not heard of it, so probably not something from Utah...

I'm not sure if this was mentioned already, but it's worth noting that Alan Stern is ... chief scientist and mission architect of Moon Express (one of the GLXP teams).
Helium-3? Why?
In the book I wrote on the subject, "Return to the Moon: The Exploration, Enterprise, and Energy in the Human Settlement of Space," is basically a business plan on how you would do that. And if you believe that business plan and you meet the milestones in the business plan, so investors continue to support you, I think within 15 to 20 years you could have a settlement on the Moon from the time you start your first investment-related activity.But you need that first step. And actually, the first step has nothing to do with power production. The first step is probably one where you are going to use Helium 3-deuterium reactors, at about the current level of development, to produce medical isotopes. It turns out that the fusion product, the protons, are ideal for radiating certain kinds of elements to produce isotopes that are important to positron emission tomography (PET) - positron emitting isotopes that have short half-lives. Right now, PET diagnostics, which is the diagnostic of choice for a particular stage of cancer, uses a relatively long half-life positron emitter of Fluorine-18 isotope and it decays in a half-life of 110 minutes. And that's great. It doesn't seem too long but it's too long for children and pregnant women to be able to take advantage of that technology because of the residual radiation.Whereas with proton irradiation, you can produce isotopes that have half-lives of 12 minutes or less so that changes the whole paradigm of how you do cancer diagnostics for children and pregnant women. That is probably the first business opportunity of this technology. It's on the pathway to producing power downstream but it is also a business opportunity that can attract investors.
Current demand is driven by neutron detectors (esp. homeland security applications).Using alternatives or ramping up He3 production here on earth would probably be easier than scouring lunar regolith for the stuff.

Why?I know, I'm having a hard time trying to see them justify a commercial endeavour centered around He3.There is a big part of me inside thinking that something WAS found on the moon, something worth persuing, and this is the attempt to lay claim on it....

It's not quite commercially viable to bring gold back from the moon, nor Platinum. Now something like Iridium - maybe, but there has to be an absolute use & need for it, perhaps a new technology, that would be worth while.
Some uninformed speculation:Since it is well known that NASA is currently developing plans to explore space beyond low earth orbit, is it possible that the subject of this thread is simply an offer by a consortium of private companies to provide an affordable lunar landing mission? In other words, is it possible that the customer is NASA?
I'd like to see the 1967 treaty challenged and amended. If you allow private rights to certain resources, it will make the 1960s space race look like 2 guys racing go-carts. IMO...

That treaty was signed for one main reason: To save money for the state by removing all incentive to invest in space...In the current climate of austerity, getting rid of a treaty whose main reason was to save money is the last thing on any politician's mind. And private enterprise does not make or break international treaties.
