[JKCalhoun]

I believe it was his book where he describes the moon hanging there as they were closing in on it. This massive, plaster-of-paris sphere almost filling his view.

His description (ignore mine above) made me realize just how remarkable that must have been to see. The Earth diminishing to a ball is one thing, but this atmosphere-less, white desert, Little-Prince-like, moon bearing down on you sounds like something else entirely.
