Alright, the Proper Space Base(tm) has started!
First of all, the needlessly over-engineered ressource exchange area linking the station with Nauvis. Yes, it is very likely that a simple "wait 20 seconds" condition of the train would have been enough, instead I went with a system of constant combinators on the station asking the ground for x amounts of each ressources. Once the train has a full load of something only then he is allowed to leave the ground for the space station. So far it works fine but if throughput becomes and issue I can also takes stuff like copper, iron and steel off the main train and deliver them via rockets in ingot form (since they're already being made on another planet) to free up some wagons or worst case I have plenty of space on both sides to add some individual trains dedicated to single ressources.
Ground exchange also has something I wanted to test for a while now. To regulate the supply train stations I setup some S/R latches so that they stay open until the buffers are full and only reopen once said buffers are close to empty, makes the train traffic around it more efficient.
But before I can start doing proper Science!, I need to set up the logistics.
First, recycling. Material science in particular kicks up a prodigeous amount of scrap that needs to be recycled. It does give you a lot of free ressources so well worth doing properly.
And next fluids and data cards, together with the junk card recycling (lots of later research can fail, so you need to recycle more stuff).
Data card production is currently at 300/min, I can still slam some speed modules to increase production, hopefully it'll be enough. Also data card production are looking like a prime candidate to receive their copper straight in ingot form since it's already eating 50 copper per seconds.
THE SPACE FACTORY MUST GROW!
