Spaceport THX1138

The space station had three large docking areas, or wings, around a central superstructure, plus two other struts. It was similar in design to a star base that operated earlier, during the Clone Wars. Its billboards, advertisements, map displays, and arrival/departure screens displayed information in Aurebesh, High Galactic alphabet, and another written script.

• , including Levels A through D, included a large video screen that displayed advertising and information about the spaceport and its travel agencies. It also displayed Imperial recruiting messages and listed some of the Empire's most-wanted criminals.

• , housing the Bespin Direct and Dantooine Express terminals

• , housing the Air Alderaan, Tatooine Transit and Naboo Spacelines terminals

• , housing the Star Tours travel agency terminal. The main terminal area through which passengers passed to board flights included a large viewscreen displaying flight information and advertisements, and had room to house and repair a StarSpeeder 1000. The flight information was color-coded to indicate the destination of the flight: Arrivals were red and departures blue. Ramps from the terminal led to security and boarding areas, all of which commonly had droids and other equipment stored in plain view of passengers. The station also included the Lightspeed Lounge and an observation deck. Signage in the station was usually displayed in Aurebesh, High Galactic and in an unidentified Imperial script. Prior to each departure, the WA-7 service droidAly San San frequently made a public service announcement, with the designated StarSpeeder 1000 being brought up via cargo elevator to the departure area. The boarding gates also came in numeric and letter variants, the latter going from A to D. The starport also featured a Restricted Customs Area.

• : This section, located west from the X Wing, and immediately next to the west side of the North Wing, contained levels A, B, C, F, and G. These sections contained the Outer Rim Restaurant and Lounge, the air-to-ground transportation section, the Muunilinst Credit Exchange for exchanging currency with various planets, the Stargazer Grill Restaurant, and the Nebula Trillion Parsec Club for spacers. The air-to-ground transportation section required public transportation to get to the surface, and made use of ships such as SSP freighters, , independent star cruisers, personal shuttles, and . The currencies that could be exchanged at the Muunilinst Credit Exchange included Republic credits, Imperial credits, Adumari credcoins, Aurodium coins, Corellian credits, and Credit Vouchers.

Early in the Galactic Civil War, shortly after the space terminal opened, Imperial agents entered the station to arrest a Rebel spy that was a passenger on a StarSpeeder 1000 flight preparing for departure. The target vessel fled the station in a firefight and escaped into hyperspace.

The space station was unnamed in the Disney's Hollywood Studios and Disneyland versions of the Star Tours: The Adventures Continue ride, but the ride's queue in Tokyo Disneyland later included a video billboard which named the station and provided additional details, which was further confirmed for English-speaking audiences with the release of the StarWars.com blog entry Convenient Daily Departures: The History of Star Tours. The name is yet another Star Wars reference to George Lucas' film THX 1138.

Depending on which scenario is randomly chosen for the ride, the scene regarding the Imperials' discovery of a spy stowed on board the ST-1401 will have one of two outcomes. In one, several stormtroopers attack the vessel while Han Solo, himself in a run-in with several stormtroopers, aids the shuttle in escaping, also attacking a Star Destroyer when they exit the station. In the second, the ship is stopped midflight by Darth Vader using the Force, only to be let go when R2-D2 uses its onboard cannons to blast at Vader, who then sends a squadron of TIE/LN starfighters after it into space.
