Conquer the Space Biome in Oxygen Not Included
This is a demonstration of my favorite advanced design for the space biome. You will need steel and petroleum. It is 99.5% transparent to light for solar panels, auto-sweeps all the regolith and metals, relatively simple, flexible, uses very little room, is highly tolerant of modifications to accommodate your space-y projects, and doesn't use space age materials.
