Most folks are still not being allowed to appreciate our moon's L1. Of
course, most Americans are still pretty much dumbfounded and/or having
been snookered about a great many such important things in this
infomercial skewed life as we've been allowed to know of. Perhaps those
more intelligent members in support of the China National Space
Administration/CNSA are as such less snookered than we're giving them
credit for.

Basically, the average free-gravity-zone of this moon L1 is supposedly
r33.5~r34 away from the moon and otherwise merely r51 from Earth
(unfortunately there's still no hard-scientific and thus independently
replicated proof of such actually being the case of those specific
numbers), that's worthy of obtaining micro if not nano and even pico
gravity, although nearly any +/- adjustment in the net gravity can be
accommodated and rather efficiently interactively sustained.

Within this interactive moon L1 pocket (+/- wherever it has to be) there
should be as little as 1% the atoms/cm3 and of the required velocity is
roughly 9 fold less than LEO (those factors alone represent a rather
huge reduction in orbital friction, and thereby greatly minimizing
station-keeping energy demands). There's also no pesky gauntlet of Van
Allen belt radiation or SAA like nasty pocket of magnetosphere stored
radiation. It's also nearly always sunny as well as having either
earthshine and/or moonshine at your disposal, and of that moonshine so
happens to include a great deal of useful secondary/recoil photons in
the IR/FIR spectrum, plus offering loads of gamma and hard-X-rays
because there's so little mass between L1 and the highly reactive naked
surface of the physically dark and cosmic morgue that's represented by
our moon.

The moon's L1 is not technically a problem for most robotics, however
our frail DNA will demand a great amount of shielding that's similar to
8 meters of water, and for any long term (multi year) human involvement
demanding 16 meters of water unless an artificial magnetosphere can be
sustained. There's also the pesky matter of having to survive various
meteors of potentially lethal flak that isn't the least bit moderated in
velocity nor being gravity diverted.

This fancy enough "Clarke Station" document that's nicely revised and
certainly rather interesting but otherwise seriously outdated,
http://www.lpi.usra.edu/publications...aryland01b.pdf
not to mention way under-shielded unless incorporating 8+ meters of
water plus having somehow established an artificial magnetosphere, or
perhaps incorporating 16+ meters of h2o if w/o magnetosphere (shielding
that's necessary because it's parked within 60,000 km from our
physically dark and otherwise highly reactive moon that's continually
providing such a not so DNA friendly TBI worth of gamma and
hard-X-rays), is simply a downright deficient document about sharing the
positive science and constructive habitat/depot considerations for
utilizing the moon's L1. In fact, there's hardly any mention of the
tremendous L1 benefits to humanity, much less as to space exploration or
the daunting task of salvaging our mascon warmed environment, and it's
still not having squat to do with any primary task of actually
developing, exploiting or otherwise terraforming the moon itself.

On the other hand, whereas the CM/ISS portion of the LSE which I've
proposed offers 50t/m2 of outter shell or hull shielding for
accommodating the 1e9 m3 interior, thereby multiple decades if not an
entire lifetime can be afforded, as to safely accommodating our frail
DNA. That may seem like a rather great amount of tonnage deployment,
though eventually 99.9% is derived from the moon itself. Of course,
don't mind anything that I have to suggest, whereas you can keep
thinking as small and/or as insignificant as you'd like. However, our
having remained as LEO/terrestrial sequestered isn't going to help us
explore, pillage and rape the other planets and of their moons, not to
mention the mining and/or possible terraforming potential of digging
into our very own global warming moon that's chuck full of nifty and
rare elements.

I guess what's needed is an open mindset that isn't afraid of it's own
shadow, that isn't afraid of making a few honest mistakes nor
demonstrating that perhaps we're not exactly the smartest nor the most
entitled species of DNA in this universe. (sorry about that)

A subject worthy of discussion. Has Arthur C expressed an opinion about
it?
