But in pure O2 lots of things burn that "shouldn't", like
asbestos fibers. This actually happened long before that
Apollo capsule burned up, and should have alerted NASA.
If our lunar atmosphere is pure O2, then every dust cloud
kicked up by a lunar buggy creates an explosion hazard.
It will have to be "diluted". Can nitrogen be generated ?
What other gases would work ? Helium would leak away too
quickly and incidentally create a Planet of the Ducks.

Sorry for rehashing what was posted earlier, or , even worse, what may now
be common knowladge, but what is this about ice at the poles of Mercury?
Since Mercury rotates, although slowly, ice would be baked off the surface,
then would leak into space due to the low gravity.
Also, to answer Nicks anti-lunar base stance: if you buy the theory, any of
them, that the moon was part of the earth, or was formed with it in the early solar system, then there is no reason that both bodies are composed of the same elements in similar quantities. Read: it has signifigant amounts of Si, Fe, C,
O etc. Is it mineable? Well we won't know until we get there(personally or through probes).

If I remember the press release correctly, NASA is now providing metric
equivalents in parentheses after the standard British units. (Someone ought
to tell the PR people about precision in numbers when they do the conversion.)
In about a year or two, NASA will switch to providing standard metric units
with the British units in parantheses. Finally, after a few years the British
units will be dropped entirely.
I believe, also, that all new starts after 01 Oct 93 must be in metric.
As for SSF, there was considerable debate about two years back about whether
to convert it to an all-metric station. The cost -- in the tens of millions
of dollars -- was deemed too great. SSF is not metric.
