Spacedock was the largest Starfleet spacedock structure in near-Earth orbit. It was originally conceived as a military base for ship repairs and refits. Spacedock orbited Earth just within the Van Allen radiation belts and was imagined as having a total height of over three miles. At that size, the facility could easily be visible with the naked eye from the surface of Earth.

The accompanying magazine explores the detailed design and specifications of the space station, as well as its history.
