Help me plz

I'm very confused, I repaired the Arora and went to a few more life pods, made some improvements to my base, but I really like base building and was wondering how I make the multipurpose room, like where do I go to scan the parts, I don't care if you spoil the while game, because I k ow what happeneds, just please tell me how I get this and how I progress further in the game because I don't know where to go or what to do
