Delta-Vega Station
Delta-Vega Station was an unmanned lithium cracking station on the planet Delta Vega, operated by the Galactic Mining Company. The station was fully automated, with visits from ore ships once every 20 years. It contained potentially explosive fuel bins and at least three fission chambers, as well as an area which could be used as a prison cell.
In 2265, when the USS Enterprise was disabled after an encounter with the galactic barrier, Spock recommended that the Enterprise crew adapt some of the station's power packs to regenerate the ship's engines. Captain James T. Kirk also decided to hold Gary Mitchell in the station's prison cell; however, Mitchell was able to escape. (TOS: "Where No Man Has Gone Before")
