In case people are wondering. There are four kinds of space base for use on airless worlds.
Actual: above ground, artificial atmosphere, glass dome, uses solar radiation for power and for botanics.
Substrate: At least partially underground, extending deep below the crust, drawing power from geothermics or natural radioactives.
Abstract: several, smaller interconnected bases, often not originally designed to be a single base.
Isolate: 100% self-contained, underground. Basically a space station buried under the surface of an airless world. Typically get power from internal fusion plants.
