Both the regular and glass versions of the space station require electric engines.
To create electric engines I need lubricant and for lubricant I need heavy oil.
I looked through the technology tree, the factoriopedia, the mod page and explored the planet at length and I do not see any way to natively build those.

Am I meant to simply import those? Or am I missing something obvious?

I will note that I am on version 1.5.5 of the mod, which is fairly old.
This is my first time using this website so I'm sorry if I broke some etiquette.
