Man In The Moon

 We talk a lot about putting men on the moon. But if we actually colonize Earth's airless satellite, we won't have men on the moon.

We'll have men (and all other genders) in the moon. It turns out that the moon likely has huge lava tubes...large enough to build entire cities in them.

Building underground is a no brainer when you are trying to colonize a world with no atmosphere or magnetosphere. These lava tubes, some of which are 3,000 feet in diameter and longer than 40k would contain settlements that ran along the tube, likely with some kind of transit system (possibly maglev) in the center. Cities would spread entirely longitudinally.

Visitors from Earth would probably find the geometry as difficult to start with as the gravity.

But if we colonize the moon, that's how we'll almost certainly do it.
