Well, it depends on how you define "striking landing sites". A direct
impact is as you know very improbable. But, there could be a speck of
dust ejected into one of Armstrong's footstep, even if the actual impact
is 1000 km away.

I wonder how much was wiped out when the LEM took off.

no doubt many footprints were scoured by the exhaust, not so much on
flights where astronauts walked or drove far distances.

still its good to protect whatever remains

That naked surface attracts all sorts of impacts that would never be
drawn anywhere near ISS. *ISS is still protected extensively by the
geomagnetic field surrounding us, whereas the physically dark and
naked moon has no such protective benefits. *Each surface impact on
the moon also generates millions of secondary shards capable of
individually moving at more than a km/sec if not nearly or even above
escape velocity. *That moon is also surrounded by a substantial cloud
or exosphere of its own highly ionized sodium.

at the time of apollo nasa said the moon had gained a atmosphere of
sorts, the LMs exhaust... small but still there.....

wonder how much might remain? most probably disappated by now

The continuous loss of helium should represent a clue, as well as for
the continuous subliming of lunar sodium that's solar heated, ionized
and wind blown for more than 900,000 km before dropping below 5/cm3,
as such would have to suggest that anything of those Apollo era vapors
has long since been heated, ionized and blown away.

What sort of heavy rocket fuels were being used?

Was their rocket exhaust of a sufficiently greater molecular density
than that of the individual fuel elements?

Such heated vapors of even heavy element liquids or as vapor rocket
fuels should not have stood a chance of sticking around as atmosphere,
unless by night they managed to reform into their solid forms and
otherwise as sunlit heated vapors were simply too heavy for those
solar winds to extract before the next nighttime freezes everything
solid.

An ice cube exposed to that heated hard vacuum environment should have
been explosive, as it instantly (perhaps within a fraction of a
millisecond) sublimed into mere particles of perhaps no greater than
3e5/cm3, of what once constituted that solid ice cube form of h2o.
The UV separated elements of water vapor being hydrogen and oxygen are
each too light as to sticking with the extremely low gravity of that
naked and extremely hot surface environment, and once exposed they
should have been easily extracted and quickly ionized by the 300+ km/
sec of the passing solar wind.

Too bad they never got to pee on a hot moon rock, because at least
that sort of objective science could have been most useful and
entertaining at the same time. I bet they could have peed a stream
for better than 100 yards, not that anything but sublimed and ionized
molecules of their pee would have ever been detected, if anything…

There are probably near no defense related jobs in pittsburgh and
besides i was never interested in finding more ways to kill people....

but knowing some friends in defense related jobs, while regular jobs
pay well at 20 bucks a hour the defense jobs pay 3 times that.

Well, here in Houston there are lots of aerospace jobs with NASA. *They
have good salaries for engineers and professionals but it doesn't pay
as well as the oil industry nearby. * Gov't contractors don't get a lot
of profit. *The oil companies have no such restrictions. * Pick your
industry and be happy with it or move on.

Actually, if including the considerable benefits as valuable NASA job
perks, the pay is quite high, although perhaps still not as good as
what the DoD, NIF and their Pentagon get access to. Creating and
improving weapons plus their various methods of delivery is still top
pay with the least amount of job foreclosure risk. They actually get
to live quite large, even on retirement pay that usually includes two
or more retirements combined, plus always those terrific benefits that
civilian jobs simply do not cover because they are usually way too
spendy.
