So I'm kinda new to KSP, and trying to build a space station for the first time. I've watched some vids on yt abiut how to build one, but don't understand what modules I should have. I know i should have one for the core, for crew, fuel, science, and power, but i forget if there are any others. Are there any modules that I forgot that I should integrate into my space station?
