A week ago, we had a movie night/book launch party at my home, and we watched First Man, the excellent biopic about Neil Armstrong, which of course culminated (SPOILER ALERT!) with the successful first landing on the moon.
A few days after that, I watched First Men in the Moon on Turner Classic Movies, an oldie based on the H.G. Wells novel (how closely, I do not know). In this film, the first explorers traveled to the moon in 1899, and the story was rather different. The plot revolved around our hapless explorers finding a race of large, bug-eyed creatures called Selenites living in the moon, in a complex of caverns beneath the lunar surface.
Now I’ve just finished watching the recent Nova episode: Back to the Moon, about how and why we might—after 50 years!—return to the moon to stay. Most of the information was familiar, but something new I learned is that apparent sinkholes have recently been discovered on the moon—holes in the surface, possibly connected to subsurface tunnels and maybe even caverns! The upshot: One location real lunar settlers might pick to build their shelters is in existing tunnels and caverns beneath the lunar surface—just like the Selenites!
You go, H.G. Wells.
