[extropy-chat] SPACE: Back to the Moon (?)

[Brian Shores]

I've heard some ideas a while back about making some form of concrete
with the regolith... maybe they could mix some nice polymers in with it
and also make it sprayable and just spray it over the module shells?
Also a double layer shell might be a partial solution to the leak
issue... just add some sensors in the outer shell and intermediate space
and go in between the shells to patch? Aah maybe there's a simpler
solution; I am just playing with some ideas here.

Would some kind of electromagnetic shielding help in any way versus
radiation, assuming one could be developed that was powerful enough? Is
it really just high energy emissions people are most worried about? This
is a bit out of my experience here, any ideas? :)

Peace,

Artillo

1/6 g should do okay for pretty long stays. It may require a heavy
exercise
schedule.

Two days transit. No problem, unless you run into a major solar storm
with no
shielding.

Right. Not that short stays will need any more shielding than the
landing
module provides.

How much regolith do you need to emulate the shielding Earth's
atmosphere
provides? 1 m, maybe two.

Hello? You seem to think we're doing lunar mining here?

If you're deep, a leak is no problem: material shields. Patching from
the
inside as well: polymerizable monomer in situ. Leaks will happen
(everything
we sent up to LEO has been leaking like a sieve) but there
are enough volatiles to replenish the losses on Luna.
