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.
I'm half-way through reading this at the moment and I cannot recommend it highly enough. In the prologue he talks of being able to turn to any page and find something interesting to read. He's not wrong.
