Have you seen NASA's moonbase illustrations
that have appeared off-and-on over the past 40 years?

I know you have!

What's wrong with those illustrations of NASA's planned moonbases,
especially that proposed and designed for George Bush's "Back-to-the-Moon" project ?

Plenty!

For one thing, not one of those numerous illustrations and designs
commissioned by and for NASA that I've seen shows a lunarbase module covered/shielded
by lunardust/regolith....or buried in the stuff.

Doesn't NASA get it?

You have to protect astronauts and their living quarters on the moon
from cosmic radiation, solar flares, and meteorites [micro and macro]
Excavating into the lunar surface and burying moonbase modules
is a must....And yet the solution is simple and has been known for many years....

For instance: Burying a lunar module under 2-3 meters of dust/regolith will protect
the module from direct hits from meteorites upto the size of a marble, traveling
at speeds upto 10-15 km/sec.
Anything larger will not [statistically] directly hit any of those modules within a human's lifetime...
And that protective covering of dust/regolith will also keep the astronauts living within safe from solar flares
and reduce their cosmic ray exposure over a year to an acceptable level.

So you see, a lunar backhoe [either robotic or equipped with a pressurized cabin]
will end up being a very important piece of equipment for a moonbase.
In fact, such a lunar backhoe could end up being more important to a moonbase
than a reliable source of polar ice.

You've tackled so-called problems like "lunar dust' on HZ, which aren't real problems;
nothing that a humidifier, soap-and-water, and a electrostatic neutralizer can't solve
easily.

I think the lack of toilet paper at a moonbase will be a bigger problem than that.
