Yes, the moon has a tenuous, cyclical ground-hugging shroud
of electrostatically-levitated microscopic dust particles that
"perhaps" rise upto to one or two hundred meters above the lunar
surface.
Why?
Because solar ultra-violet radiation [and to a lesser extent, solar x-rays]
ionizes this fine lunar dust, permitting sustained [lunar daylight] dust levitation.

During the 14 day lunar night, what happens to the dust?
Answer: It will have a tendency to regain its electrically neutral state,
or equilibrium, as far as electric charge is concerned during the lunar night .
You can actually perform an inexpensive crude experiment using a sealed dry room,
a UV light source [with an on-off switch], & very fine talcum powder to prove this.
The extremely fine powder will take days to settle out of the air in that room
once the ultraviolet light is turned off, but it will settle out.

You want to do OPTICAL astronomy on the moon?
Do it during the lunar night on the surface.
Optical astronomers will practically salivate at the opportunity to
carry out a sustained exposure of a distant extremely faint celestial target
for nearly 14 days.
As lunar daylight approaches hermetically seal that optical telescope prior to lunar sunrise.
[You could also build an observation tower, hundreds of meters high, on
the lunar surface, "when" a sustained, industrial lunar-society is achieved]
OH YES!....Optical astronomers on the moon will have the added benefit
of being able to carry out mid-infrared optical astronomy at the natural
ambient lunar night-time temperatures without the need of using liquid nitrogen.

I will only touch briefly on the so-called health threat posed by lunar dust.
Solutions to that problem have already been worked out.
Engineers are not stupid people.

OH! And Mars has fine dust in its atmosphere.
Comets and the stony or carbonaceous asteroids? They have fine dust levitated
above them too.
In fact dust is ubiquitous throughout the cosmos....does that mean we stop sending
humans beyond LEO?
iIn some ways, sending humans to colonize Mars maybe more dangerous and hazardous to health
than lunar colonization.
A Mars colony, using a near-pure oxygen atmosphere will run the risk
of exposing elemental sulfur rich rocks and soil to that oxygen...You don't want SO2 gas
developing inside a Mars colony; it will ruin their day.
Have any of you ever accidently inhaled even a small amount of SO2 gas?
I unfortunately have....I never want that to happen again.

no other life."
