I can't read the article due to a paywall, but I assume it talks about Jules Verne etc.? I really hope they also included Herge's "Tintin - From the Earth to the Moon" (and "Explorers on the Moon"). I remember reading that as a kid which triggered my whole fascination with the US/Soviet space program.
I believe it was written in the early 50's but still had the concept of a nuclear powered rocket, and a moon rover vehicle etc.
