Spaceways are used to connect vehicles with either stations, satellites, or other ships. The Spaceway has been used to connect The Christa to such places as the Starcadamy and the satellite that Pezu occupies.
The Space Cases Bible notes that the Spaceways are made of "concentrated graviton particles," although originally the Spaceway was to extend from the "underbelly" of the ship as opposed to the landing bays in the "eyes". [1]
