Roger Bagula,
Can I add a little something extra as to terraforming our moon?

Actually, I have hundreds of questions with respect to what our moon
could have to offer.

The moon will lose an earthlike atmospheare if it is given one. At the
heat flux rate from the sun it sees the gas will leak off in a
relitivly short amount of time. Once that air is gone, it is gone, and
cannot be recovered.

"Relatively short" only in a geological sense. The "half-life" of a lunar
atmosphere is measured in the thousands of years.

Once that air is gone, it is gone, and
cannot be recovered.

For any civilization advanced enough to give the moon an atmosphere in the
first place, it would be child's play to replenish the atmosphere by the
fraction of a percent per year necessary to keep it there.

Which is the sort of time scale that you engage in when terraforming.

It would take about that long to add the atmosphear.

From where?

Regardless the N2 is in short supply in terms of avalability of atoms
in the solar system, and when they escape from an atmosphear, they are
not recoverable in any practical manner.

Sealed habitats would lose less, and need less N2 or O2 or H20 for a
given weight of plants or animals. In the earth's atmosphear I think
you can see that air above about 250 feet off the ground is wasted
other than as radiation shielding. A few million pressureized habitats
will be safer in the long run IMHO.

Now, are you talking about a moon that looks like Earth's moon now, or a
moon that looks like Mars, or a moon that looks like Venus?

I saw that episode of "Space: 1999"! It came and went in a day- complete
with rain!

I'll bet *that* played havoc with the corrosion inhibitors on Moonbase
Alpha's skin!

I wanted to see more than one or two episodes of that show. Sigh.

Still, the rate of loss of the atmosphere will be governed by physics,
not by the whim of a screen writer. And it will be on the order of
hundreds to thousands of years.

Duh. This is a project for civilizations that think long-term.

From whence they choose - remember, we are talking about a civilization
capable of placing an earth-like atmosphere on the moon in the first place.

Regardless the N2 is in short supply in terms of avalability of atoms
in the solar system, and when they escape from an atmosphear, they are
not recoverable in any practical manner.

Why do you need N2? Any inert buffer-gas will do.

N2 is not exactly inert.

It is very important to plant cycles and animal life. Much if not all
of the Nitrogen atoms that you use in your body (a lot that you cannot
live without) were chemically processed out of N2 by plants and
converted into organtic Nitrogen compounds.

If you want to "terraform" a planet, you need nitrogen. If just adding
an atmosphear for sh*&s and grins, no N2 is needed.
