time machine (disambiguation)for other, similarly-named pages.
Space-time travel did not necessarily require a vehicle. It could be achieved by use of a vortex manipulator or time ring, (TV: The Sound of Drums, Genesis of the Daleks) though "time travel without a capsule" was usually painful. (TV: Blink, The Sound of Drums)
Whereas a "time machine" moved the user through time and a spaceship moved the user through space, a space-time vessel combined these abilities to enable the user to visit anywhere in the universe at any time.
Often these vehicles had dimensionally transcendental properties and utilised the Time Vortex. The TARDISes of the Time Lords were an example of this. The Daleks copied these properties and integrated them into their Dalek time machines. (TV: The Chase)
Space-time craft, at least around the 23rd century, were powered by Zeiton-7 mined on the human colony of Varos, (TV: Vengeance on Varos) although humans were not due to develop time travel until the 30th century. (PROSE: Transit) The Daleks' time machines were powered by taranium. (PROSE: Mission to the Unknown)
