(1) How large in diameter is SpaceDock at it's largest? How tall is that same section, where the ships are ported? (2) How tall is SpaceDock in its entirety? (3) How wide and tall are the docking bay doors? (4) I know they used the same studio model from ST3 for the "11001001" episode of TNG, but isn't there some in-universe explanation that two of the four doors were enlarged for the Galaxy-class? (5) Are there free-flow doors into SpaceDock for shuttles and construction ships? I can't imagine they leave the doors open at all times, so is there some kind of permanently-open "service entrance"? (6) What speculation is available for the purposes of the portions of SpaceDock below the big saucer-like Dock module itself? Thanks for any tips, speculation, or nudges in the right direction, folks.
