My go at the spaceport diorama.
@Grant_Abbitt : I used to be a Swing Arms engineer for the Space Shuttle, around 20 years ago. I don’t know if it is different for these sorts of rockets, but if memory serves the structure on the launch pad was colloquially just called The Tower, or the Service Structure. There were two pieces of it, one of which rotated when there was no vehicle at the pad, and then rotated closer to the vehicle once it was in place. The other piece did not move. These were known as the Rotating Service Structure (RSS – everything is an acronym at NASA) and the Fixed Service Structure (FSS). Most of the time, people would just use FSS or RSS to refer to it.
looking good
