The others (Jay & STS) have better experience with this than I, but for my experience, atomic oxygen was primarily a LEO issue.

Youíre both right. LDEF and our satellite were both Shuttle-deployed and retrieved, so they were in LEO. Sorry for the lack of context, since this discussion is focused on the space around the Moon.

Compared to the world population, actual spacecraft engineers may be overrepresented in this thread.

And do you have a problem with? I like experts to give their feedback on items within their field.

I'm one of the spacecraft engineers.

I for one prefer to get a well-rounded view. What does the common man on the street think about the reactivity of atomic oxygen in low earth orbit?

Yeah, sorry if that was unclear. LDEF was a LEO experiment. You have entirely different materials issues if you want to fly to the Moon. But it popped into my head because of Apollo 12 wanting to see what long exposure to the lunar surface environment had done to Surveyor hardware. Actual experimentation is still our best method of understanding the effects of various space environments on materials. So going back to where we've already placed human-made objects isn't as boring as it sounds.
