I take no credit for the vast majority of this base. It started off as a blueprint titled, 1k SPM / Belt Fed (LTN). I have looked for the original author to credit them, but to no avail. After 2.0 and the removal of the Rocket Control Unit and Satellite from Space Age, I was able to cut off about a quarter of the base dedicated to building rockets and satellites to produce Space Science from 4 silos. I repurposed some of the existing raw material lines into making all the necessary Space Platform parts (using blueprints from the book Modular Rocket Builder by Slapping Tree https://www.factorio.school/view/-OBMXnR3t08j7OxyN5kV) as well as feeding a Rocket Silo factory (by Gabriel Santos https://factorioprints.com/view/-OGgq2YFTrjfZaKm73w0).
Again, I want to point out that I am not the creator of the main components of this blueprint. The only thing I did other than fix the broken rail lines, was add a small rail stop to bring Solid Fuel for refueling the trains as they stop to unload materials.
