 until that time in the 60s, and then I guess corresponding with us going to the moon at the end of the 60s. Is there something I'm missing?

Well, there's actually a period of time in the 20s and 30s and 40s where science fiction has seemed to be a literature written largely for adolescent boys, just for a kind of entertainment purpose.
