This is a model of Earth Spacedock, as seen in a couple of the Star Trek movies. This station was made to be a hub for much of the Federation's starship traffic, and as a major hub of operations for Starfleet.

Planned features:
-Miniature Mozzie-scale ships!
-More blocks!
-More Details!
-an outer ring of stuff!
-Fast Transit system!
-And much more! So much more, I don't even know what yet!

Is this scale? Nope! It stretches from the bottom to the top of the world, and is probably about 1/2 to 1/3 the size of the actual station. Due to Minecraft's build limit, it is actually impossible to build a 1:1 scale model of this station in one piece. It could be built to scale by building parts of the station separately, and using MCEdit and a height mod to put them together. But that would be a lot of work, and I don't have that kind of time.

Currently on hiatus, trying to finish my dreadnought.
