The TARDIS used from 2005 to 2010 on display at BBC Television Centre

The TARDIS[nb 1][1] (/ˈtɑːdɪs/; Time and Relative Dimension in Space)[nb 2] is a time machine and spacecraft in the British science fiction television programme Doctor Who and its associated spin-offs The Sarah Jane Adventures, Torchwood and more.

A TARDIS is a product of the advanced technology of the Time Lords, an extraterrestrial civilisation to which the programme's central character, the Doctor, belongs. A properly maintained and piloted TARDIS can transport its occupants to any point in time and any place in the universe. The interior of a TARDIS is much larger than its exterior, which can blend in with its surroundings using the ship's "chameleon circuit". TARDISes also possess a degree of sentience (which has been expressed in a variety of ways ranging from implied machine personality and free will through to the use of a conversant avatar) and provide their users with additional tools and abilities including a telepathically based universal translation system.

In the series, the Doctor pilots an apparently unreliable, obsolete Type 40, Mark 1[2][3] TARDIS. Its chameleon circuit is broken, leaving it stuck in the shape of a 1960s-style London police box after a visit to London in 1963.[4] The Doctor's TARDIS was for most of the series' history said to have been stolen from the Time Lords' home planet, Gallifrey, where it was old, decommissioned and derelict (and, in fact, in a museum).[5] However, during the events of "The Doctor's Wife" (2011), the ship's consciousness briefly inhabits a human body named Idris, and she reveals that far from being stolen, she left of her own free will. During this episode, she flirtatiously implies that she "stole" the Doctor rather than the other way around, although she does also refer to him as her "thief" in the same episode.

The unpredictability of the TARDIS's short-range guidance (relative to the size of the Universe) has often been a plot point in the Doctor's travels. Also in "The Doctor's Wife", the TARDIS reveals that much of this "unpredictability" was actually intentional on its part in order to get the Doctor "where [he] needed to go" as opposed to where he "wanted to go".

Although "TARDIS" is a type of craft rather than a specific one, the Doctor's TARDIS is usually referred to as "the" TARDIS or, in some of the earlier serials, just as "the ship", "the blue box", "the capsule" or "the police box". [nb 3]

Doctor Who has become so much a part of British popular culture that not only has the shape of the police box become more immediately associated with the TARDIS than with its real-world inspiration, the term "TARDIS-like" has been used to describe anything that seems to be bigger on the inside than on the outside.[6] The name TARDIS is a registered trademark of the British Broadcasting Corporation.[7]

Conceptual history[edit]

When Doctor Who was being developed in 1963, the production staff discussed what the Doctor's time machine would look like. To keep the design within budget,[8] it was decided to make it resemble a police telephone box. This was explained in the context of the series as a disguise created by the ship's "chameleon circuit", a mechanism which is responsible for changing the outside appearance of the ship the millisecond it lands in order to fit in with its environment. The Ninth Doctor explains that if, for example, a TARDIS (with a working chameleon circuit) were to materialise in ancient Rome it might disguise itself as a statue on a plinth. The First Doctor explained that if it were to land in the middle of the Indian Mutiny, it might take on the appearance of a howdah (the carrier on the back of an elephant). A further premise was that the circuit was broken, explaining why it was "stuck" in that form.

The idea for the police-box disguise came from BBC staff writer Anthony Coburn, who rewrote the programme's first episode from a draft by C. E. Webber.[9][10] In the first episode, "An Unearthly Child", the TARDIS is first seen in a 1963 junkyard. It subsequently malfunctions, retaining the police box shape in a prehistoric landscape.

At the time of the series' debut in 1963, the police box was still a common fixture in British cities. It provided a direct telephone link to the local police station; the telephone was located behind a small, hinged door, making it possible to use it from the outside, while the box itself was used as a temporary office containing a desk. In "The Empty Child" (2005), the Doctor stated that the telephone is not connected to a telephone line, and in Logopolis (1981), the Master materialised his TARDIS around a normal police box while a police officer was using the telephone, causing the line to go dead. However, in "The Day of the Doctor", the Doctor successfully used the telephone.

The police box prop that was the first to be built for the programme was designed by Peter Brachacki, who worked as designer on the first episode.[11] Nevertheless, one story has it the box came from Z Cars,[12] while Doctor Who producer Steven Moffat has said that the original TARDIS prop was reused from Dixon of Dock Green,[13] although this is explicitly contradicted by the research cited on the BBC's own website.[14] Despite changes in the prop, the TARDIS has become the show's most consistently recognisable visual element.

The dimensions and colour of the TARDIS props used in the series have changed many times, as a result of damage and the needs of the show, and none of the BBC props has been a faithful replica of the original MacKenzie Trench model.[15] This was referenced on-screen in the episode "Blink" (2007), when the character Detective Inspector Shipton says the TARDIS "isn't a real [police box]. The phone's just a dummy, and the windows are the wrong size."[nb 4][16]

The production team conceived of the TARDIS travelling by dematerialising at one point and rematerialising elsewhere, although sometimes in the series it is shown also to be capable of conventional space travel. In the 2006 Christmas special, "The Runaway Bride", the Doctor remarks that for a spaceship, the TARDIS does remarkably little flying. The ability to travel simply by fading into and out of different locations became one of the trademarks of the show, allowing for a great deal of versatility in setting and storytelling without a large expense in special effects. The distinctive accompanying sound effect – a cyclic wheezing, groaning noise – was originally created in the BBC Radiophonic Workshop by Brian Hodgson. He produced the effect by dragging a set of house keys along the strings of an old, gutted piano. The resulting sound was recorded and electronically processed with echo and reverb. When employed in the series, the sound is usual synchronised with the flashing light on top of the police box, or the fade-in and fade-out effects of a TARDIS (see "Controls" below). The comic strip feature of Doctor Who Magazine traditionally represents the ship's distinctive dematerialisation sound with the onomatopoeic phrase "vworp vworp vworp". The sound itself was heard during a segment of the 2012 Summer Olympics opening ceremony in London as rock band Queen's Bohemian Rhapsody was played to the stadium.

In 1996, the BBC applied to the UK Patent Office to register the TARDIS as a trademark.[17] This was challenged by the Metropolitan Police, who felt that they owned the rights to the police box image. However, the Patent Office found that there was no evidence that the Metropolitan Police – or any other police force – had ever registered the image as a trademark. In addition, the BBC had been selling merchandise based on the image for over three decades without complaint by the police. The Patent Office issued a ruling in favour of the BBC in 2002.[18][19]

General characteristics[edit]

TARDISes are bioships that are grown from a species of coral presumably indigenous to Gallifrey, as stated in "The Impossible Planet" (2006), and it can take years to complete one. They draw their power from several sources, but primarily from the Eye of Harmony, an exploding star in the process of becoming a black hole suspended in a permanent state of decay. In The Edge of Destruction (1964), the power source of the TARDIS (referred to as the "heart of the TARDIS") is said to be beneath the central column of the console. They are also said to draw power from the entire universe as revealed in the episode "Rise of the Cybermen" (2006), in which the TARDIS is brought to a parallel universe and cannot function without the use of a crystal power source from within the TARDIS, charged by the Doctor's life force.

Other elements needed for the proper functioning of the TARDIS and requiring occasional replenishment include mercury (used in its fluid links), the rare ore Zeiton 7 (Vengeance on Varos, 1985), a trachoid time crystal (The Hand of Fear, 1976) and "artron energy". Artron energy is said to be the "residue of TARDIS engines", and is also found in Time Lord brains and bodies of other time travellers (The Deadly Assassin, 1976; Four to Doomsday, 1982; The Wedding of Sarah Jane Smith, 2009; Death of the Doctor, 2010; "The Doctor's Wife", 2011; "The Power of Three", 2012). Another form of energy, "huon energy", is found in the heart of the TARDIS and (apart from the activities of the Torchwood Institute) nowhere else in the universe ("The Runaway Bride").

Before a TARDIS becomes fully functional, it must be primed with the biological imprint of a Time Lord, normally done by simply having a Time Lord operate the TARDIS for the first time. This imprint comes from the Rassilon Imprimatur, part of the biological make-up of Time Lords, which gives them both a symbiotic link to their TARDISes and the ability to withstand the physical stresses of time travel (The Two Doctors, 1985). Without the Imprimatur, molecular disintegration would result; this serves as a safeguard against misuse of time travel even if the TARDIS technology were copied. Once a time machine is properly primed, however, with the imprint stored on a device called a "briode nebuliser", it can be used safely by any species.[nb 5] According to Time Lord law, unauthorised use of a TARDIS carries "only one penalty", implied to be death ("The Invasion of Time").

A TARDIS usually travels by dematerialising in one spot, traversing the time vortex, and then rematerialising at its destination, without physically travelling through the intervening space. However, the Doctor's TARDIS has been seen to be able to fly through physical space, first in Fury from the Deep (1968) and at repeated times throughout the revived series, most notably in "The Runaway Bride" (2006), in which the TARDIS is shown launching into space (most previous incidents show the TARDIS flying only after it has dematerialised from a location). In "The Runaway Bride", extended flight of this nature puts a strain on the TARDIS's systems. While a TARDIS can materialise inside another, if both TARDISes occupy exactly the same space and time, a Time Ram will occur, resulting in their mutual annihilation (The Time Monster). In Logopolis, the Master tricked the Doctor into materialising his TARDIS around the Master's, creating a dimensionally recursive loop, each TARDIS appearing inside the other's console room. In the mini-episodes "Space" and "Time" (2011), an accident results in the TARDIS automatically materialising in "the safest spot available", which turns out to be inside its own control room.

Apart from the ability to travel in space and time (and, on occasion, to other dimensions), the most remarkable characteristic of a TARDIS is that its interior is much larger than it appears from the outside. The explanation is that a TARDIS is "dimensionally transcendental", meaning that its exterior and interior exist in separate dimensions. In The Robots of Death (1977), the Fourth Doctor tried to explain this to his companion Leela, using the analogy of how a larger cube can appear to be able to fit inside a smaller one if the larger cube is farther away, yet immediately accessible at the same time (see Tesseract). According to the Doctor, transdimensional engineering was "a key Time Lord discovery". To those unfamiliar with this aspect of a TARDIS, stepping inside the ship for the first time usually results in a reaction of shocked disbelief as they see the interior dimensions ("It's bigger on the inside!"). The Eleventh Doctor is particularly fond of this reaction, and is surprised and confused when Clara Oswald (in "The Snowmen") inverts the usual response by saying "It's smaller on the outside."

Susan Foreman, the Doctor's granddaughter, claimed to have coined the acronym TARDIS: "I made [it] up from the initials."[20] The word TARDIS is used to describe other Time Lords' travel capsules as well. The Discontinuity Guide, written by Paul Cornell, Keith Topping, and Martin Day, suggests that "[she] was a precocious young Time Lady, and her name for travel capsules caught on."[21] The Virgin New Adventures novel Lungbarrow by Marc Platt records Susan telling the First Doctor that she gave him the idea when he was, implicitly, the "Other".

As seen in The Trial of a Time Lord (1986), the experiences of the TARDIS and its crew can be recorded and played back from the Matrix, the Time Lord computer network that is the repository of all their knowledge, as well as the memories and experiences of deceased Time Lords. The Doctor implies in this serial, with his protestations of being "bugged", that the TARDIS is not normally connected to the Matrix in this manner.

The TARDIS has been shown to be incredibly rugged, withstanding gunfire (the 1996 television movie, Doctor Who; "The Runaway Bride"), temperatures of 3000 degrees without even scorching ("42"), atmospheric re-entry ("Voyage of the Damned"), falls of several miles ("The Satan Pit") and sinking into pooling acid ("The Almost People"). In The Curse of Peladon, after the TARDIS falls down the side of a cliff, the Third Doctor remarks that it "may have its faults, but it is indestructible." This does not apply when facing certain extremely advanced weaponry, often created after the Doctor's Type 40 TARDIS, such as Dalek missiles ("The Parting of the Ways"), for which the TARDIS requires additional shielding. Another piece of advanced Dalek technology which comes near to destroying the TARDIS is the power source of the "Crucible" in "Journey's End" (2008). In Frontios (1984), the Fifth Doctor believes the TARDIS to have been destroyed in a meteorite bombardment, apparently contradicting the earlier claim of indestructibility. It explodes in The Mind Robber (1968) and the crew end up "out of the time space dimension. Out of reality." In 2007's Christmas special "Voyage of the Damned", the TARDIS is hit in mid-flight, creating a large hole in the interior wall, although its shields are down at the time. The Doctor later activates some controls and the TARDIS again becomes able to withstand an atmospheric re-entry. Also in the 2013 episode "The Name of the Doctor" the TARDIS is shown to be able to withstand immense speeds, pressure and heat by being pulled into Trenzalore's atmosphere without any functioning systems. The only noticeable damage caused was to the exterior of the TARDIS, in which a small crack is shown on the glass.

The Doctor's TARDIS[edit]

In the programme, the Doctor's TARDIS is an obsolete "Type 40 TT capsule"[3] that he unofficially "borrowed" from the repair shop when he departed his home planet of Gallifrey.[22][23][24] That incident was referred to as early as 1969, but not shown on screen for another 44 years, in a scene where future companion Clara Oswald advised him the specific capsule to take: although the navigation systems were malfunctioning it would be much more fun.[25]

The TARDIS was already old when the Doctor first took it, but its actual age is not specified. In the unfinished TV serial Shada, fellow Time Lord Professor Chronotis said that the Type 40 models came out when he was a boy. There were originally 305 registered Type 40s, but all the others had been decommissioned and replaced by new, improved models.[3] According to the Eighth Doctor Adventures novel The Gallifrey Chronicles by Lance Parkin, the Doctor's TARDIS previously belonged to a Time Lord named Marnal, who was, like the Doctor, something of a renegade. The spin-off media have, on a number of occasions, had the TARDIS wait around for the Doctor for decades and even centuries in relative time. By the time of The Pirate Planet, the Doctor had been travelling on board in time and space for 523 years, by the time of "The Doctor's Wife", he had been travelling in it for 700 years, and in "Journey to the Centre of the TARDIS" he had been travelling for 900 years. In "The Empty Child" (2005), the Ninth Doctor claimed that he has had "900 years of phone box travel".

The appearance of the primary console room has changed over the years, sometimes in minor ways and sometimes drastically when the set has had to be moved or rebuilt. This has often been rationalised in the scripts as redecoration, the ship's own ability to reconfigure or repair itself,[26][27] or even a change of "desktop theme".[28] In "The Doctor's Wife" the TARDIS says she has thirty desktops archived, although the Doctor has only changed it a dozen times "yet".

In the 2011 episode "The Doctor's Wife" the "soul" of the ship is transferred into the body of a humanoid female called Idris, enabling the Doctor to have a conversation with his craft. The TARDIS says that she deliberately allowed the Doctor to "steal" her, as she wanted to see the universe itself; in a reversal of the traditional view, the TARDIS claims to have stolen the Doctor. When he accuses the TARDIS of being unreliable, she defends herself by saying that she has always taken him where he "needed to go", as opposed to where he "wanted to go". During their brief opportunity to converse, the TARDIS expresses both affection and frustration with the Doctor (including annoyance that he pushes her doors open rather than pulls them open as the instructional sign on the outside indicates). When asked by the Doctor if she actually has a name, she self-identifies with the name "Sexy", based upon what the Doctor calls her when he's alone in the ship (she later introduces herself to the Doctor's companions using this name). Eventually, the Idris "avatar" dies, and the last words uttered by the TARDIS to the Doctor using this interface are "I love you." Two additional pieces of information confirmed by the TARDIS during this incident are that TARDIS consciousnesses are female and that she and the Doctor have been travelling for approximately 700 years.[29]

In a later episode, "Let's Kill Hitler" (2011), the Doctor speaks to the TARDIS by way of a holographic voice interface. In this instance, after providing options including an image of himself and former companions, the TARDIS manifests as an image of Amelia Pond as a child. In "Hide" (2013), companion Clara Oswald interacts with a similar interface outside the TARDIS' doors when it refuses to open for her. In a subsequent mini-episode entitled "Clara and the TARDIS", further animosity between Clara and the ship's consciousness is indicated when the TARDIS reconfigures her internal layout to prevent Clara from finding her bedroom. However, following The Name of the Doctor - in which her leap into the Doctor's time stream is what facilitated the Doctor and Susan to steal that TARDIS instead of the adjacent one that they had intended to take - the TARDIS's animosity appears to have disappeared as Clara is now shown as able to close the TARDIS doors with a click of her fingers.

Exterior[edit]

The undisguised appearance of a Type 40 TARDIS' exterior is a silver-grey cylinder only slightly larger than a police box. Its door is recessed and slides to open. This default state has appeared only in 2013's "The Name of the Doctor", which depicts the TARDIS's original theft by the Doctor.

Although a TARDIS is supposed to blend inconspicuously into whatever environment it turns up in, the Doctor's TARDIS retains the shape of a police box because of a fault that occurred in the first Doctor Who serial, An Unearthly Child. The ability to alter its appearance was first mentioned in the second episode of the series, where the First Doctor and Susan noted the unit was malfunctioning. ("It's still a police box! Why hasn't it changed?") It was first given a general term of a "camouflage unit" in The Time Meddler (1965). The name "chameleon circuit" was first used in the 1975 Target Books novelisation of The Terror of the Autons, and eventually mentioned on screen in Logopolis (1981). The circuit was called a "cloaking device" by the Eighth Doctor in the Doctor Who television movie, and again a "chameleon circuit" in the 2005 series episode "Boom Town".

The Doctor attempts to repair the circuit in Logopolis and Attack of the Cybermen, but the successful transformation of the TARDIS into the shapes of a pipe organ, a painted Welsh dresser (much to the amusement of Perpurgilliam "Peri" Brown and the Sixth Doctor's annoyance) and an elaborate gateway in the latter serial was followed by a return to the police box shape. The circuit was also repaired during the Virgin New Adventures novels, but again the TARDIS's shape was eventually set back to a police box shape. In "Boom Town" (2005), the Ninth Doctor implied that he had stopped trying to fix the circuit quite some time ago because he had become rather fond of the police box shape – a claim the Eighth Doctor made in the 1996 television movie.

Cosmetically, the police box exterior of the TARDIS has remained virtually unchanged, although there have been slight modifications over the years. For example, the sign on the door concealing the police telephone has been black letters on a white background (An Unearthly Child), white on blue (The Seeds of Death) and white on black (The Curse of Peladon). Other modifications include different wordings on the phone panel; for example, "Urgent Calls" (An Unearthly Child) as opposed to "All Calls" (Castrovalva publicity photos). The "POLICE BOX" sign was wider from Season 18 (1980) onwards and for the 2005 series, but not for the television movie. From An Unearthly Child (1963) to The War Machines (1966), the TARDIS also had a St. John Ambulance badge on the main doors, as did real police boxes;[30] this has been reinstated and the window frame colour has returned to white for Matt Smith's first season as the Doctor, shown in 2010. "The Empty Child" showed that the telephone cupboard could be opened and the telephone accessed from the exterior, but this device was then non-functional.[31] The telephone can however be called from across space and time.[32] Because of the St. John Ambulance badge, 11th-century monks considered the telephone's ring to be "the bells of Saint John".

Despite the anachronistic police box shape, the TARDIS's presence is rarely questioned when it materialises in the present-day United Kingdom. In "Boom Town", the Doctor simply noted that humans do not notice odd things like the TARDIS, echoing a similar sentiment expressed by the Seventh Doctor in Remembrance of the Daleks (1988), that humans have an "amazing capacity for self-deception". Various episodes, notably "The Sound of Drums", also note that the TARDIS generates a perception filter to reinforce the idea that it is perfectly ordinary.

When the TARDIS "died" with the Doctor in battle in an alternate timeline, it became his tomb on the grave fields of the planet Trenzalore. Although the tomb retains its police box exterior appearance, its interior volume begins to "leak", growing the exterior to hundreds of feet in height.[25]

Doors and lock[edit]

For most of the series' run, the exterior doors of the police box operated separately from the heavier interior doors, although sometimes the two sets could open simultaneously to allow the ship's passengers to look directly outside and vice versa. The revived series' TARDIS features no such secondary doors; the police box doors open directly into the console room. The entrance to the TARDIS is capable of being locked and unlocked from the outside with a key, which the Doctor keeps on his person and occasionally gives copies of to his companions. In the 1996 television movie, the Doctor kept a spare key "in a cubbyhole behind the 'P'" (of the POLICE BOX sign). In The Invasion of Time, a Citadel Guard on Gallifrey is initially baffled by the archaic lock when attempting to open the Doctor's TARDIS.

The Doctor almost always opens the doors inwards, despite the fact that a real police box door opened outwards; in "The Doctor's Wife", it is revealed that the TARDIS is aware of this and finds it annoying. After crash-landing on its back in Amelia Pond's garden in "The Eleventh Hour", the doors uncharacteristically open outward, as they had previously done when the TARDIS was also on its back in The Ice Warriors; additionally, the left door opened in tandem with the usual right door in these instances. When hovering against a building in the same 'doors-up' horizontal orientation in "Day of the Moon", however, the doors opened inward as usual to receive River Song.

In the 2005 series, the keys are also remotely linked to the TARDIS, capable of signalling its presence or impending arrival by heating up and glowing. The TARDIS keys have varied in design from an ordinary Yale key[33] to an ankh-like key embossed with an alien pattern (identified in Terrance Dicks and Malcolm Hulke's 1972 book The Making of Doctor Who as the constellation of Kasterborous, Gallifrey's home system) from seasons 11 to 13, after which it reverted to the Yale key design.[34] The ankh-like key was also used in the 1996 television movie. In Ghost Light and Survival, a different design, featuring the Seal of Rassilon, was used.[35] The revived series uses the Yale key version, most notably shown in "Blink" (2007), when the Weeping Angels attempt to gain access to the TARDIS using a stolen key.

The key is also able to repair temporal anomalies and paradoxes, including death aversion, through its link to the TARDIS.[36]

The TARDIS lock's security level has varied from story to story. Originally, it was said to have 21 different "combinations" and would melt if the key was placed in the wrong one (The Daleks, 1963). The First Doctor was also able to unlock it with his ring (The Web Planet, 1965) and repair it by using the light of an alien sun refracted through the ring's jewel (The Daleks' Master Plan). In The Dalek Invasion of Earth (1964) and "Utopia" (2007), the TARDIS was shown to have an internal deadlock; once thrown, it would prevent entry even for authorised users with authorised keys. In The Dalek Invasion of Earth, this was known as 'double-locking'. In The Sensorites (1964), the entire lock mechanism was removed from the TARDIS door via a hand-held Sensorite device.

The lock itself has been shown with different capabilities. In Spearhead from Space (1970), the Third Doctor said that the lock had a metabolism detector, so that even if an unauthorised person had a key, the doors would remain locked. This security measure was also seen in the New Series Adventures novel Only Human by Gareth Roberts, which called it an "advanced meson recognition system." The Ninth Doctor claimed that when the doors were shut, even "the assembled hordes of Genghis Khan" could not enter ("believe me, they've tried") ("Rose"). In "Doomsday", when the TARDIS is confiscated, the Doctor claims, "You'll never get inside it." Several people have managed to just wander into the TARDIS without any problem over the years, including some who became companions; since the TARDIS uses keys, it could easily have been left unlocked. Despite the TARDIS's apparent infallibility in its security, some of the instruments inside or the interior itself have been breached and remote-controlled. In the serial The War Games, the Time Lords manage to breach the inside of the TARDIS while in mid-flight and landing in order to erect something similar to a force field. In "Utopia", the Doctor is able to lock the TARDIS to the coordinates it had previously visited from outside using the sonic screwdriver. In the episode "The Rings of Akhaten", Clara Oswald cannot get into the TARDIS and says, "I don't think it likes me!"

In the 2008 episode "Forest of the Dead", River Song (a character whose timeline intersects with the Doctor's in non-linear order) says to the Doctor that she knows he would be able to open the TARDIS doors with a snap of his fingers. Although the Doctor dismisses this as impossible, at the conclusion of the episode, he opens and closes the doors by doing just that, eschewing the need for a key. He is later shown doing the same in "The Eleventh Hour" and "Day of the Moon", and, in "The Day of the Doctor" (2013), despite the previous animosity the TARDIS displayed towards her, Clara Oswald is also shown as able to shut the doors with a snap of her fingers.

In the 2009 Christmas episode, part one of The End of Time, the Doctor uses a remote locking system to lock the TARDIS, similar to the remote-control locking system used on modern cars. Upon pointing his key fob at the TARDIS, the TARDIS makes a distinctive chirp and the light on top of the TARDIS flashes. Later in the same episode, the key fob, when again used by the Doctor, shifts the TARDIS "just a second out of sync" (one second into the future), rendering it invisible and so hiding it from the Master.

The doors are supposed to be closed while materialising; in Planet of Giants (1964), the opening of the doors during a materialisation sequence caused the ship and its occupants to shrink to doll size. In The Enemy of the World (1967), taking off while the doors were still open results in an uncontrolled decompression, causing the villainous Salamander to be blown out of the TARDIS. In Warriors' Gate (1981), the doors open during flight between two universes, admitting a Tharil named Biroc, and allowing the time winds to burn the Doctor's hand and seriously damage K-9. In "The Runaway Bride" (2006), "The Stolen Earth" (2008) and subsequent stories, the doors can be opened safely while the ship is in a vacuum, as the TARDIS protects its occupants (see the "Defences" section below); in The Horns of Nimon (1979), the Doctor deliberately extrudes the "defence shield" to dock with a spacecraft.

There is evidence that objects clinging to the outside of the TARDIS may be carried with it as it dematerialises. In Silver Nemesis (1988), an arrow is fired at the TARDIS and is embedded in its door. The arrow remains in the door throughout the serial and through several dematerialisations before being removed at the story's conclusion; this is repeated in "The Shakespeare Code" (2007), and the arrow is removed in the following episode, "Gridlock". "Utopia" presents, for the first time on-screen, a circumstance in which a character travels on the exterior of the TARDIS during a flight, when Jack Harkness grabs hold of the TARDIS as it began to dematerialise and hold on until it reaches its destination; the episode does establish, however, that a normal person would not have survived the trip, as Jack is "killed" by the experience, but due to his immortality, soon revives. This concept was altered for The Time of the Doctor where Clara also travels with the TARDIS by holding on to its exterior. To prevent Clara from dying the TARDIS has to drastically slow down its time travel, arriving 300 years too late with a visibly aged Doctor shouting where has it been all this time. In "Vincent and the Doctor" (2010), some advertisements are attached to the TARDIS. After materialisation, they are shown to be burning.

In the Seventh Doctor audio drama Colditz, a character was killed by being halfway inside the TARDIS when it dematerialised.

Exterior influence[edit]

The Time Lords are able to divert the TARDIS's flight path (The Ribos Operation (1978)), or have the ability to totally override and recall any TARDIS by the order of the Council (Arc of Infinity (1983)). Alien influences have also, for example, trapped the Doctor's TARDIS and drained its power in The Web Planet (1965) and Death to the Daleks (1974), while its course has been diverted by The Keeper of Traken (1981), the Mandragora Helix (1976) and by the Daleks' "time corridor" in Resurrection of the Daleks (1984). In The Mark of the Rani (1985), the Rani used a Stattenheim remote control to summon her TARDIS. In The Two Doctors (1985), the Second Doctor also used a portable Stattenheim. The Doctor used his sonic screwdriver to trigger remotely "Emergency Programme One", sending his human companion Rose Tyler to safety, while he stayed behind for a battle against the Daleks (The Parting of the Ways (2005)). The Doctor also manipulated the TARDIS by utilising the self-attracting nature of huon particles, causing the TARDIS to materialise around both Donna Noble and himself, in order to escape into the past. However, this trick was used in turn by the Empress of the Racnoss, which pulled the TARDIS from the creation of the Earth to only a few minutes after its initial departure.[37]

In "The Pandorica Opens" (2010), the TARDIS is drawn to a specific date, 26 June 2010, and then caused to explode by an outside influence.

The exterior dimensions can be severed from the interior dimensions under extraordinary circumstances. In Frontios (1984), when the TARDIS was destroyed in a Tractator-induced meteor storm, the interior ended up outside the police box shell with various bits embedded in the surrounding rock. The Doctor eventually tricked the Gravis, leader of the Tractators, into reassembling the ship. In "Father's Day" (2005), a temporal paradox resulting in a wound in time threw the interior of the ship out of the wound, leaving the TARDIS an empty shell of a police box. The Doctor attempted to use the TARDIS key in conjunction with a small electrical charge to recover the ship, but the process was interrupted and the TARDIS was only restored after the paradox was resolved.

In "Turn Left" (2008), the "Police Box" sign and all other text on the TARDIS is shown as replaced with the words "Bad Wolf", as is all text in the universe; this is interpreted by the Doctor as an urgent warning concerning the end of the universe. The words "Bad Wolf" have also been spray-painted on and around the TARDIS in previous episodes. The TARDIS has the ability to turn invisible, allowing it to avoid the detection by President Nixon, Canton Everett Delaware III and Area 51 operatives ("The Impossible Astronaut", "Day of the Moon" (2011)).

Interior[edit]

The TARDIS wardrobe from "The Christmas Invasion"

The TARDIS interior has an unknown number of rooms and corridors, and the dimensions of the interior have not been specified. In "Journey to the Centre of the TARDIS" (2013), the Doctor states that the TARDIS is actually infinite in size. Apart from living quarters, the interior includes a well-organised study (TARDIS, 2010), a swimming pool and bathroom, a sick bay, an ancillary power station disguised as an art gallery, and several brick-walled storage areas (all seen in The Invasion of Time, 1978); a "cloister room",[24] an observatory, a library,[38] a greenhouse, a baby room, a toy room and several squash courts.[citation needed] There is also a wooden-panelled secondary control room, and numerous other rooms have been only mentioned in dialogue or in spin-off media (see below). The Doctor flippantly mentions a karaoke bar in "The Girl Who Waited" (2011). Portions of the TARDIS can also be reconfigured or "deleted"; the Doctor was able to jettison 25% of the TARDIS's structure in Castrovalva to provide additional "thrust". In "The Doctor's Wife" (2011), a fail-safe transfers any living creatures in "deleted" rooms to the main control room, and old (and future) control rooms can be "archived" by the TARDIS without the Doctor's knowledge. Rooms within the TARDIS can be re-arranged to suit the Doctor's needs, as when the Eleventh Doctor hastily moved the swimming pool beneath the TARDIS entrance in order to catch River Song in "Day of the Moon"; alternatively he may have moved the door.

In Full Circle (1980), Romana stated that the weight of the TARDIS was 5 × 106 kilograms in Alzarius's Earth-like gravity (about 5 × 107 Newtons, or the weight of 5,000 tonnes). It has been speculated[39] that this was a mistake by the character and referred to its internal weight, as the external part of the TARDIS is at other times light enough for it to be lifted or otherwise moved with relative ease (although most real police boxes were concrete and hence quite difficult to move): several men lift it up in Marco Polo, it is transported by truck and installed indoors by hand (all off-screen) in Spearhead From Space, it requires a fork-lift truck in Time-Flight and is lifted in the cargo hold of a Concorde in the same serial, a group of small blue maintenance workers on Platform One push it along the ground in "The End of the World", and a quartet of Weeping Angels are able to rock it back and forth in "Blink", to name a few. The TARDIS floats in Fury from the Deep but, conversely, remains stationary despite the tides in The Time Meddler. If the solid exterior of the TARDIS is moved or shaken after materialisation, the movement is usually transmitted to its interior ("The Impossible Astronaut", 2011), although there is a manual control to separate the internal gravity from the exterior's orientation (Time-Flight, 1982).

In the tie-in novels, the interior of the TARDIS has been known to contain an entire city (Cat's Cradle: Time's Crucible), used to encompass an entire parallel Earth (Blood Heat), and is big enough to dwarf Gallifrey itself when turned inside out (The Ancestor Cell). It is also seen to exist in multiple timelines.[citation needed] In "Journey to the Centre of the TARDIS" the TARDIS is shown to contain the Eye of Harmony, an exploding star in the process of becoming a black hole.

A distinctive architectural feature of the TARDIS interior is the roundel.[40] In the context of the TARDIS, a roundel is a circular decoration that adorns the walls of the rooms and corridors of the TARDIS, including the console room. Some roundels conceal TARDIS circuitry and devices, as seen in the serials The Wheel in Space (1968), Logopolis, Castrovalva (1981), Arc of Infinity (1983), Terminus (1983), and Attack of the Cybermen (1985). The design of the roundels has varied throughout the show's history, from a basic circular cut-out with black background to a photographic image printed on wall board, to translucent illuminated discs in later serials. In the secondary console room, most of the roundels were executed in recessed wood panelling, with a few decorative ones in what appeared to be stained glass. In the TARDIS design from 2005 – January 2010, the roundels are built into hexagonal recesses in the walls. Ever since the TARDIS was redesigned at the beginning of the 2010 series, there have been a range of different roundel designs around the console room. These include circular holes that are recessed deep into the walls, hexagonal holes that are lit from behind each face, round indents with brass rings around the outside, and a glass centre that is illuminated blue.

Other rooms seen include living quarters for many of the Doctor's companions. The TARDIS also had a "Zero Room", a chamber that was shielded from the rest of the universe and provided a restful environment for the Fifth Doctor to recover from his regeneration in Castrovalva (which was among the 25% jettisoned). However, the Seventh Doctor spin-off novel Deceit indicated that the Doctor rebuilt the Zero Room shortly before the events of that novel. In some of the First Doctor serials, a nearby room contains a machine that dispenses food or nutrition bars to the Doctor and his companions. This machine disappears after the first few serials, although mention is occasionally made of the TARDIS kitchen. In The One Doctor, Mel mentions that the Doctor used the TARDIS's laundromat.

Although the interior corridors were not initially seen in the 2005 series, the fact that they still exist was established in "The Unquiet Dead", when the Doctor gives Rose some very complicated directions to the TARDIS wardrobe. The wardrobe is mentioned several times in the original series and spin-off fiction, and seen in The Androids of Tara (1978), The Twin Dilemma (1984) and Time and the Rani (1987). The redesigned version, from which the Tenth Doctor chooses his new clothes, was seen in "The Christmas Invasion" (2005) as a large multi-levelled room with a helical staircase. Designer Ed Thomas has suggested that more rooms may be seen in coming episodes.[41] The corridors were eventually seen in the episode "The Doctor's Wife", and are currently standing sets for use in future episodes. The Doctor also mentions in "The Shakespeare Code" that the TARDIS has an attic.

In "The Eleventh Hour", the Doctor mentions that the TARDIS has a library and a swimming pool. He tells Captain Avery that there are several bathrooms available in "The Curse of the Black Spot" (2011). The swimming pool has been seen on-screen in The Invasion of Time (1978), and the Doctor later used it to catch River Song as she plummeted from a skyscraper. The swimming pool, the scullery, squash court 7, the archived Ninth and Tenth Doctor's console room, and Amy and Rory's quarters were ejected in the episode "The Doctor's Wife." The Doctor reconstructed Amy and Rory's bedroom but replaced the bunk beds with a normal bed at their insistence. The swimming pool was seen again briefly in "Journey to the Centre of the TARDIS" indicating it was later rebuilt as well.

In the "Doctor Who: Adventure Games", the TARDIS has a "drawing room" containing items that the Doctor has used in past episodes, like the long scarf the Fourth Doctor used, the Second Doctor's recorder and items like the Fob Watch used to change the Doctor's Time Lord biology to human in the episode "Human Nature". The Drawing Room is the Doctor's private study, and the Doctor advised Amy Pond not to mess around with anything, and no one is allowed to sit in his chair.

Console room[edit]

The console room from the 1983 20th anniversary special to the 1989 series

The most often-seen room of the TARDIS is its console room, where its flight controls are housed. The console room was designed by Peter Brachacki and was the only set he designed for the show. It was built on a shoestring budget and a tight schedule, which led to Brachacki leaving the show due to disagreements with the production team and possibly a feeling that he had been given an impossible task. Despite his leaving the show and mixed reactions as to how the set looked (producer Verity Lambert liked it but director Waris Hussein did not), the basic design of the hexagonal console and wall roundels has persisted to the present day.[42]

The TARDIS has at least two console rooms: the primary one most used throughout the programme's history, and the secondary console room used during Season 14 in 1976/77, which has wood panelling and a more antique feel to it. It had been designed to make shooting more comfortable for the camera crew. Putting the console on a dais meant the cameramen no longer had to crouch for eye-level shots. However the set walls warped after it was put into storage at the end of production and had to be discarded.

In addition, a cavernous, steampunk-inspired[citation needed] console room was used in the television movie and may have been a reconfiguration of either of the previously mentioned console rooms, as first suggested in New Adventures novels, most specifically the Lungbarrow by Marc Platt, where the TARDIS reconfigures the console room to reflect the interior of the Doctor's former home and later in the Big Finish Productions audio plays.

In the Third Doctor serial The Time Monster (1972), the console room of the TARDIS was dramatically altered, including the wall roundels. This new set, designed by Tim Gleeson, was disliked by producer Barry Letts, who felt that the new roundels resembled washing-up bowls stuck to the wall. As it turned out, the set was damaged in storage between production blocks and had to be rebuilt, so this particular design only saw service in the one serial.

In the 2005 series, the console room became a dome-shaped chamber with organic-looking support columns, and the interior doors were removed. The change in configuration is explained in "Time Crash" by the Fifth Doctor as a mere changing of "the desktop theme" to "Coral" (he also indicates that a "Leopard Skin" theme is also available, but he dislikes it). Other preceding theories involve the fact that the TARDIS interior was severely damaged by a cold fusion explosion in The Gallifrey Chronicles.[citation needed] Several episodes of the revived series, such as "Army of Ghosts" and the end of "The Unicorn and the Wasp", reveal that there is storage space directly underneath the console room; the Doctor is shown periodically obtaining equipment from this area via a panel in the floor. The 2005 console room was destroyed by the regeneration energy of the Tenth Doctor in the final scene of The End of Time and cold open of "The Eleventh Hour", although it made a reappearance in the 2011 episode "The Doctor's Wife" as well as the 50th anniversary special The Day of the Doctor. This console room has made the most appearances in the revived series, and is the most well known one. A new console room, along with a new police box exterior, made its debut in the Eleventh Doctor's first episode, which aired on 3 April 2010. It was revealed in "The Doctor's Wife" that the older TARDIS interior designs are not destroyed or remodelled, but 'archived' off the official schematic without the Doctor's knowledge. The TARDIS reveals that she has around thirty console rooms archived, even those that the Doctor has yet to use. These archived console rooms are still capable of controlling TARDIS functions as shown when Amy and Rory are able to lower the TARDIS shields from an archived control room. The active console room at a given time will be the one connected to the exterior doors for ingress and egress.

A third console room design was unveiled in the 2012 Christmas special "The Snowmen".[43] As opposed to the more open, unpredictable nature of the previous design, this set echoes the machine-like 1980s TARDIS console, but is coloured in the more shadowy blues, greens and purples of the 1996 TV movie. Though the central pillar is still connected to the ceiling – a design element introduced in the 1996 movie, and continued in the 2005 series – it is now joined to three circular connectors marked with Gallifreyan symbols that twist clockwise and anticlockwise when the TARDIS is in flight.

Showrunner Steven Moffat stated that the new design was meant to be more 'scary' and machine-like than the previous bright orange design, which was more 'whimsical' to reflect upon the light-hearted and fairy-tale-like nature of the episodes following its introduction in "The Eleventh Hour".[44] The seventh series' darker, more adult tone necessitated a more menacing and mysterious console - also reflecting the implications that the TARDIS is distrustful of the Doctor's companion, Clara. For instance, in "Hide", Clara's statement that the TARDIS actively dislikes her is intercut with footage of its' circular connectors spinning from the ceiling.

A previously unseen version of the console room made an appearance in the 2013 serial The Day of the Doctor and is associated with the War Doctor portrayed by John Hurt. This console room has walls that are similar in design to those first seen in 1963, with multiple roundels illuminated from behind.

The console room is the "safest place on the ship," and so when its occupants are in danger the TARDIS will reinvent its architecture so as to allow them to enter the console room. This can also result in the TARDIS materialising itself within its own console room when in grave danger, as it did in "Space" and "Time". As seen in "Journey to the Centre of the TARDIS", the console room is able to be replicated any number of times to create "echo rooms"; occupants in each of the different echo rooms will be able to feel the presence of the others in the forms of shadows and sounds, as the rooms are together for a brief second, with the rooms rapidly alternating between each other, "like a light switch ... flickering at super-infinite speeds."

The Virgin novels introduced a tertiary console room, which was described as resembling a Gothic cathedral (Nightshade by Mark Gatiss). Another novel (Death and Diplomacy by Dave Stone) suggested that the native configuration is so complex and irrational that most non-Time Lords who witness it are driven mad from the experience.

Throughout the programme's history there have been various attempts at humanising the console room by adding various accoutrements. For example, a hatstand has often been located somewhere in the room, and the first episodes featured an ormolu clock. In the series from 2005 onwards, the TARDIS console included a bench sitting area for the Doctor and/or his companions to relax during extended flight. In The Androids of Tara (1978) a cupboard containing fishing gear is shown nearby. In "The Rebel Flesh" (2011), a dartboard is seen installed in the console room, and it is revealed in the episode "Vincent and the Doctor" that the console is capable of playing recorded music. In keeping with the darker and more machine-like setting of the 2012 redesign of the console room, there is no hat-stand or bench; in "Hide", the Doctor and Clara both note that there is no longer anywhere in the room on which to hang Clara's umbrella.

TARDIS console[edit]

The main feature of the console rooms, in any of the known configurations, is the TARDIS console that holds the instruments that control the ship's functions. The appearance of the primary TARDIS consoles has varied widely but shares common details: hexagonal pedestals with controls around the periphery, and a moveable column (or time rotor as it has been called in the original series and the 2011 episode "The Doctor's Wife") in the centre that bobs rhythmically up and down when the TARDIS is in flight, like a pump or a piston.

The arrangement of the controls implies that the console was designed to be manned by more than one person. One piece of fan continuity, used in the spin-off media, and also mentioned by the current production team, is that the intended number of operators is somewhere between three and six. In "Journey's End", the Doctor confirms that the intended number is six; Rose Tyler, Martha Jones, Sarah Jane Smith, Mickey Smith, Jack Harkness and the Doctor man the controls, and the TARDIS runs far more smoothly during that brief period than it normally does. This also explains why the Doctor tends to do a lot of manic running around the console while he is piloting the TARDIS, as well as the occasional difficulty he has in controlling it, although Romana, the Doctor's one-time Time Lord companion, is able to pilot the TARDIS successfully by herself. Companion Professor River Song, herself a de facto Time Lord who was conceived aboard the TARDIS while transiting the time vortex, was also shown to pilot the TARDIS smoothly and easily without help ("The Time of Angels", "The Pandorica Opens", "Let's Kill Hitler", "The Angels Take Manhattan").

The console can be operated independently of the TARDIS. During the Third Doctor's era, he occasionally detaches the console from the TARDIS to perform repairs on it. In Inferno (1970) the Doctor accidentally rides a detached console into a parallel universe. He and Idris (the human body in whom his TARDIS' "soul" was placed) flew a detached console to the Doctor's TARDIS in "The Doctor's Wife".

The console room from the 1996 television movie

The central column is often referred to as the "time rotor", although when the term was first used in The Chase (1965) it referred to a different instrument on the TARDIS console. However, the use of this term to describe the central column was common in fan literature, and was finally used on screen to refer to the central column in Arc of Infinity (1983) and Terminus (1983). The current production team uses the term in the same way. It was also referred to as the "time column" in Logopolis (1981).

The secondary console was smaller, with the controls hidden behind wooden panels, and had no central column. The 1996 television movie console also appeared to be made of wood and the central column connected to the ceiling of the console room. The new series' console is circular in shape and divided into six segments, with both the control panels and the central column glowing green, the latter once again connected to the ceiling.

The 2005 console has a much more thrown-together appearance than previous consoles, with bits of junk from various eras substituting as makeshift controls, including a glass paperweight, a locomotive style water sight glass and protector, a small bell, and a bicycle pump, the latter identified in the Tenth Doctor interactive mini-episode "Attack of the Graske" as the vortex loop control. Three other controls—the dimensional stabiliser, vector tracker, and the handbrake—were also identified, but although the stabiliser had been mentioned before in the series, the canonicity of the mini-episode is also unclear. As seen in "World War Three", there is also a working telephone attached to the console. In the 2010 series, the new console includes items such as a washer-fluid bottle from a car and a typewriter keyboard.

Precisely how much control the Doctor has in directing the TARDIS has varied over the course of the series. The First Doctor did not initially seem to be able to steer it accurately, making only one intended landing to the planet Kembel in The Daleks' Master Plan (1965–6) by using the directional unit taken from another TARDIS before the unit burns out. During the Third Doctor's exile on Earth, the TARDIS's course is shown as controlled successfully by the Time Lords, and from the point the Time Lords unblock his memory of time-travel mechanics in The Three Doctors (1972–3), the Doctor seems able to navigate correctly when needed.[45]

Over time the Doctor seemed to be able to pilot the TARDIS with more precision. In The Seeds of Death, the Second Doctor explains to Zoe Heriot that it would be impossible to use the TARDIS to fly from Earth to the Moon because it would likely "overshoot by a few million years, or a few million miles." However, in Logopolis, the Fourth Doctor is able to make a "short hop" to the exact coordinates when he initially lands the TARDIS 1.6 metres off target.

Following the Key to Time season (1978–79), the Doctor installed a randomiser to the console which prevented the Doctor (and by extension the evil and powerful Black Guardian) from knowing where the TARDIS would land next. This device was eventually removed in The Leisure Hive (1980).

In the 2005 and later series, the Doctor is shown piloting the TARDIS at will, although writers continue to use the plot device of having the TARDIS randomly land somewhere, or imply that the TARDIS is "temperamental" in its courses through time and space, such as missing his intended mark by a century (1879 instead of 1979) in "Tooth and Claw" (2006), making the mistake of 12 months instead of 12 hours in "Aliens of London" (2005), or getting the correct time but landing on the wrong continent (London instead of New York) in "The Idiot's Lantern" (2006). He can also choose to "set the controls to random" as in "Planet of the Ood" (2008). Although The Doctor's spacial accuracy in "The Eleventh Hour" was spot-on, the TARDIS' malfunctioning Helmic regulator prevents him from controlling the exact time he arrives at, first promising a young Amelia that he would be gone for only five minutes, but taking 12 years to return, and again when he intended to leave Amy for a short while to give the newly regenerated TARDIS a brief shakedown cruise, and ends up returning another two years in the future. In "The Doctor's Wife" the reason why the Doctor seems to lack control over the TARDIS at times is explained: the TARDIS' soul, in the body of a humanoid named Idris, explained that while the TARDIS may not always take the Doctor where he wants to go, it always takes him where he needs to go.

The Doctor in his eleventh incarnation was generally able to land the TARDIS with significantly superior accuracy to that of his predecessors; he returned four times to the same spot in Amy Pond's garden where he had crash-landed and originally met her. (2nd & 3rd arrivals "The Eleventh Hour", "The Big Bang", "The Angels Take Manhattan"); he routinely materialised in front of the London house which he had given to her and her husband ("The God Complex", "The Doctor, the Widow and the Wardrobe", "Pond Life: August", "The Power of Three"), or within her homes ("Flesh and Stone", "Pond Life: May", "Dinosaurs on a Spaceship", "The Power of Three"). He delivered himself to the precise space-time location where the pair (and, unbeknownst to them, their daughter River Song) had summoned him; ("Let's Kill Hitler") and his pin-point accurate landings repeatedly allowed him to catch River and save her life ("The Time of Angels", "Day of the Moon"). In "Asylum of the Daleks", 2012, the Doctor is able to land with "pinpoint accuracy" in the Dalek ship, but he is surprised that he can, and boasts to the Daleks and his companions that he is able to.

In "Boom Town", a portion of the TARDIS console opens to reveal a luminescent vapour within, described by the Doctor as the "heart of the TARDIS", harking back to the description in "The Edge of Destruction." In "The Parting of the Ways" (2005) it was shown that this is connected to the powerful energies of the time vortex.

The 1996 television movie was the first appearance of the central column being attached to the ceiling. However, a new design for the TARDIS console room was conceived after season 26, which featured the console being suspended from the ceiling via the central column; this design was never built because the show was cancelled before a 27th season was produced; however, the set was used in a Doctor Who night presented by Sylvester McCoy, where a miniature was built and McCoy was superimposed into it.

TARDIS systems[edit]

The console room from 2005–2010, first seen in "Rose" and last seen in "The Day of the Doctor"

Due to the age of the TARDIS, it is inclined to break down. The Doctor is often seen with his head stuck in a panel carrying out maintenance of some kind or another, and he occasionally has to give it "percussive maintenance" (a good thump on the console) to get it to start working properly. Efforts to repair, control, and maintain the TARDIS have been frequent plot devices throughout the show's run, creating the amusing irony of a highly advanced time machine which, at the same time, is an obsolete and unreliable piece of junk. Additionally, the TARDIS was designed to be flown by six experienced Time Lords, as opposed to the one Doctor piloting (and, often, not very well).

Controls[edit]

The TARDIS possesses telepathic circuits, although the Doctor prefers to pilot her manually. In Pyramids of Mars (1975), the Fourth Doctor told Sutekh that the TARDIS controls were "isomorphic", meaning only the Doctor could operate them. However, this characteristic seems to appear and disappear when dramatically convenient, and various companions have been seen to be able to operate the TARDIS and even fly it. In "Blink", the TARDIS was 'pre-programmed' to travel to a specific time (1969) and place by inserting a DVD into the console. The DVD was one of the 17 owned by Sally Sparrow on which the Doctor appeared as an "Easter egg". In this situation, however, the TARDIS dematerialised without transporting its occupants. Despite the changes in the layout of the console controls, the Doctor seems to have no difficulty in operating the ship. In "Time Crash", the Fifth Doctor is able to fly the TARDIS despite the layout being radically different from the one he was used to, at first without even noticing that the machine had changed. In the episode "Utopia", the TARDIS is taken by the Master and the Doctor is only able to use his sonic screwdriver to restrict the destination times to the last two previous selected destinations. In the Big Finish Productions audio play Other Lives (2005), the Eighth Doctor deactivates the isomorphism of the controls to allow his companion C'rizz to operate the console.

Apart from the sound that accompanies dematerialisation, in The Web of Fear (1968), the TARDIS console was also seen to have a light that winked on and off during landing, although the more usual indicator of flight is the movement of the central column. The TARDIS also possesses a scanner so that its crew may examine the exterior environment before exiting the ship. In the 2005 series the scanner display is attached to the console and is able to display television signals as well as various computing functions and occasionally what the production team has stated are Gallifreyan numbers and text.

The 2005 series also sees the addition of the tribophysical waveform macro-kinetic extrapolator to the TARDIS in the episode "Boom Town". This control was originally a pan-dimensional 'surf board' taken from the Slitheen. In "The Parting of the Ways", Captain Jack Harkness uses it to rig up a force field that defends the ship from Dalek missiles. The Doctor uses it again in the Christmas 2006 episode "The Runaway Bride", to jar it a few hundred metres off course when being dragged back to the Empress of Racnoss, in a similar manoeuvre to that used in The Web of Fear with another extra device he plugged into the console. In the last appearance, the TARDIS coral has begun to grow over the extrapolator.

In the television movie, access to the Eye of Harmony is controlled by means of a device that requires a human eye to open. Why the Doctor would programme such a requirement is retroactively explained in the Big Finish Productions audio play The Apocalypse Element, where a Dalek invasion of Gallifrey prompts the Time Lords to code their security locks to the retinal patterns of the Sixth Doctor's companion Evelyn Smythe.

The TARDIS came with an instruction manual that the Sixth Doctor claims in Vengeance on Varos to have started reading but never finished. Tegan Jovanka is unable to make sense of its contents, and Peri Brown later finds it propping open a vent. The usual function of the manual is to hold up a short leg on the Doctor's hat rack, though "Amy's Choice" features the Doctor revealing to have thrown it into a supernova, ostensibly due to disagreeing with it. Despite its complexity, some companions with exceptional intelligence, such as Nyssa, or familiarity with technology, such as Turlough and Jack Harkness, have been depicted as assisting the Doctor with TARDIS operations. In "The Sontaran Stratagem", Donna Noble displays an aptitude for piloting the TARDIS under the Doctor's guidance, much to the Doctor's apparent surprise. The Doctor's companion River Song claims to have been taught to pilot the TARDIS by "the very best" ("The Time of Angels"); this turns out to have in fact been the TARDIS herself, rather than the Doctor ("Let's Kill Hitler").

In "Journey's End", the TARDIS is shown to ideally require six pilots positioned at various stations around the central console to be piloted properly. On that occasion, the six pilots were Rose Tyler, Martha Jones, Sarah Jane Smith, Mickey Smith, Jack Harkness, and the Doctor. However, the ending of the 2011 episode "The Doctor's Wife" reveals that the TARDIS is actually capable of manipulating the controls herself (which is consistent with stories in which the TARDIS is summoned or otherwise travels by herself without the input of a pilot, such as "The Two Doctors" (1985) and "Hide" (2013).

In "The Time of Angels" (2010), River Song reveals that the TARDIS has a "stabilisation" and "brake" option. The "stabilisation" prevents the TARDIS from moving violently in flight. River Song claimed that leaving the "brakes" on is the cause of the (de)materialisation noise. However, other TARDISes have usually made the same sound when dematerialising and materialising, and it has even been identified as a particular component of every TARDIS. In "The Time of the Doctor" (2013), the Doctor is able to "turn the engines on silent". The consciousness of the Doctor's TARDIS, when briefly transposed into the body of a humanoid woman in the "The Doctor's Wife", makes the sound in order to identify herself to the Doctor and is used when the TARDIS consciousness is transferred to and from the woman.

Defences[edit]

If required, the TARDIS can become temporarily invisible, but this is a significant power drain, as seen in "The Impossible Astronaut", when the Doctor lands the TARDIS in the middle of the Oval Office in the White House.

Despite its outside appearance, the TARDIS seems to be virtually impenetrable. When being chased by an Auton in "Rose", the Doctor reassures future companion Rose Tyler that "the assembled hordes of Genghis Khan couldn't break through those doors, and believe me, they've tried."

When fully active, the TARDIS's outer defences are (nearly) impenetrable. This is demonstrated in the last episode of The Armageddon Factor. In this episode, the Black Guardian is unable to enter the TARDIS after the Doctor activates "...all of the TARDIS's defences..." The result is that the Black Guardian is unable to obtain the much-desired Key to Time. However, in "Journey's End" the Tenth Doctor states that the Daleks, created and led by Davros, would have no problem breaching the TARDIS defences. "They're experts at fighting TARDISes, they can do anything. Right now, that wooden door is just wood."

Some of the TARDIS's other functions include a force field and the Hostile Action Displacement System (HADS), which can (if switched on by the ship's operator) teleport the ship away if it is attacked (The Krotons, 1968) or in great danger (Cold War, 2013). The force field is seen in use in "The Runaway Bride", when the Tenth Doctor and the Bride, Donna Noble, are trying to escape the Empress of the Racnoss and in "The Beast Below", when the Doctor is showing Amy Pond the wonders of the universe. In "Journey to the Centre of the TARDIS", the Eleventh Doctor turns off the shields by putting the TARDIS on "basic mode" for his companion, Clara, to operate. Another device, a tribophysical waveform macro kinetic extrapolator, is installed to generate a force field in the episode "Boom Town" and is later used to protect the ship from Dalek missiles in "The Parting of the Ways".

The TARDIS's cloister bell is a signal used in the event of "wild catastrophes and sudden calls to man the battle stations" (Logopolis).

The interior of the TARDIS was described as being in a state of "temporal grace" (The Hand of Fear, 1976). The Fourth Doctor explains that, in a sense, things do not exist while inside the TARDIS. This had the practical effect of ensuring that no weapons can be used inside its environs. Since then weapons have been fired in the console room in Earthshock (1982), Attack of the Cybermen, "The Parting of the Ways", and "Last of the Time Lords", among others. When confronted by Nyssa on this contradiction in Arc of Infinity, the Doctor responded, "Yes, well, nobody's perfect." In The Invasion of Time, a guard's patrol staser will not function, even though K9's nose laser does. The Doctor explains on this occasion that the staser will not work within the field of a relative dimensional stabiliser, such as that found in the TARDIS. In the audio story Human Resources, when a character mentions the temporal grace function, the Eighth Doctor, says that his TARDIS "hasn't done that in years". In "Let's Kill Hitler" the Doctor tells the "Mels" incarnation of River Song about the temporal grace system and she shoots something in the TARDIS as a result, causing it to crash. The Doctor then admits that temporal grace is actually just a "clever lie."

The TARDIS can also use its living metal circuitry to continue to expand and change when required, as seen in "Journey to the Centre of the TARDIS", when the TARDIS creates a continuing "labyrinth" around the occupants of the TARDIS, to stop the theft of a circuit. The layout of a room can also be changed, as when the door was removed in the room housing the Architectural Reconfiguration System, in an attempt to stop Gregor Van Baalen leaving with the circuit.

The TARDIS also has another shield which keeps it from interacting with other objects in the time vortex, namely other TARDISes. When the Doctor forgets to restore these shields after the events of "Last of the Time Lords", he ends up merging his TARDIS with that of his fifth incarnation in the mini-episode "Time Crash". After successfully separating the two, the bow of the alien spaceship called Titanic, designed to look like the ship of the same name, smashes through the inside wall of the TARDIS before he can raise it again.[46] The damage is repaired, however, when the Doctor reverses time, pulling the Titanic back so the breach never occurred.[47] Despite the shield being designed to keep the TARDIS from interacting with itself, its own interior is considered the safest place, and the ship will thus effect an emergency materialisation within itself under certain circumstances. This occurred in the mini-episodes Space and Time, when Rory Williams' accidental dropping of a thermal coupling prompts the TARDIS' exterior to materialise within its interior, thereby trapping the ship and its occupants in a space loop. In "The Doctor's Wife", the Doctor's makeshift TARDIS materialises within the Doctor's own TARDIS, but only after Idris telepathically instructs the Doctor's companions, trapped aboard by the House entity, to deactivate the TARDIS's defences from an "archived" control room.

Programming[edit]

The TARDIS can be programmed to execute automatic functions based on certain conditions. The Ninth Doctor used Emergency Programme One to send Rose home in "The Parting of the Ways". It was programmed to return to the Doctor upon the detection of the presence of one of Sally Sparrow's DVDs in "Blink". Emergency Programme One will also send Donna Noble back to her own time period if she is left alone in the TARDIS for more than five hours.[48] In "Voyage of the Damned", the TARDIS will lock on to the nearest planetary body to land there when it becomes adrift in space. The TARDIS automatically repairs after too much damage, as in "Voyage of the Damned" when it repairs itself after the spaceship Titanic crashes through its walls.

Other systems[edit]

The TARDIS also grants its passengers the ability to understand and speak other languages. This was previously described in The Masque of Mandragora (1976) as a "Time Lord gift [I allow you to share]" which the Doctor shared with his companions, but was ultimately attributed to the TARDIS's telepathic field in "The End of the World" (2005). In "The Christmas Invasion", it was revealed that the Doctor himself is an integral element of this capability. Rose is unable to understand the alien Sycorax whilst the Doctor is in a regenerative crisis. In "The Impossible Planet" (2006), it is said that the TARDIS normally even translates writing; in that episode, the TARDIS is unable to translate an alien script, which the Doctor claims makes the language "impossibly old". However, the TARDIS does not translate Gallifreyan, as seen in "Utopia", when the Doctor was reading Gallifreyan numbers from the console monitor to tell where the TARDIS was going, and again in "A Good Man Goes to War", in which the Gallifreyan script on the Doctor's crib remains unintelligible to the audience and the Ponds. River Song also explains in "A Good Man Goes to War" that the TARDIS' translation matrix can take "a while to kick in" for the written word, actually coming into effect after the departure of the Doctor and the TARDIS. In the Ninth Doctor Adventures novel Only Human, the telepathic field includes a filter that replaces foul or undesirable language with more acceptable terms. In "The Fires of Pompeii", it is shown that if a TARDIS traveller speaks in a hearer's own language, the translation circuit renders these words appropriately as foreign to the listener's ear (for example, if an English-speaking TARDIS traveller speaks Latin to an ancient Roman, the Roman hears that Latin as "Celtic" or Welsh). It also affects the translation of accents: in "Vincent and the Doctor", a translated Scottish accent is heard by a Dutchman and understood as a Dutch accent (though that accent-translation was also an outside reference to the speaker and hearer both being played by actors whose native accent was Scottish). The translation circuit does not always function, even for the Doctor. In Four to Doomsday, the Doctor is unable to understand the Aboriginal dialect spoken by a tribesman and the Doctor's companion Tegan. Similarly, Martha Jones is initially unable to understand the Hath in the episode "The Doctor's Daughter" and although she is eventually able to communicate with them, the audience is never allowed to understand their words.

The TARDIS is able to tow other objects (a neutron star in the The Creature from the Pit, 1979; a ship in "The Satan Pit", 2006); or follow a ship or a transmission through space and time ("The Empty Child", 2005; and "The Stolen Earth", 2008). In "Journey's End", the TARDIS (assisted by the Rift Manipulator situated at Torchwood Three in Cardiff and the supercomputer Mr Smith) is able to tow the Earth across space.

At times the TARDIS is shown to have a mind of its own. It is heavily implied in the television series that the TARDIS is "alive" and intelligent to a degree (first in The Edge of Destruction), and shares a bond with those who travel in it; in the television movie, the Doctor calls the TARDIS "sentimental". In "The Parting of the Ways", the Doctor leaves a message for Rose when he believes he will never return, asking her to let the TARDIS die. In the same episode, Rose claims that the TARDIS is alive, echoing the Doctor's earlier statement in "Boom Town". The Doctor's TARDIS is also explicitly said to have died in the episode "Rise of the Cybermen", though the Doctor is able to revive it by giving up some of his life energy (reducing his life expectancy by a decade in the process). Other abilities the TARDIS displays include creating snow via "atmospheric excitation" ("The Runaway Bride") and, through a "chameleon arch", engineering an almost witness protection-style relocation by making its Time Lord another species and placing him/her in a newly fabricated identity with new memories somewhere else in space and time ("Human Nature", "The Family of Blood", "Utopia"). In "The Doctor's Wife", the TARDIS's intelligence is temporarily transferred to a humanoid body, during which time it is shown to possess a degree of precognition as well as limited telepathic abilities and a genuine fondness for the Doctor and his companions. This episode also demonstrates that certain capabilities of the physical TARDIS are operable independently of its intelligence, in particular the physical TARDIS's internal password security system (which is language-independent, relying on meanings rather than the words themselves) and ability to travel between "bubble universes".

The TARDIS is also able to place particular areas of the ship in "time stasis", as is in "Journey to the Centre of the TARDIS" where the engine had exploded and the TARDIS "wrapped around the force" of the explosion as a temporary safety measure.

In the novels, a portion of the TARDIS could be separated and used for independent travel. This was featured in two Virgin novels, Iceberg by Davis Banks and Sanctuary by David A. McIntee. This subset of the TARDIS, resembling a small pagoda fashioned out of jade, had limited range and functionality, but was used occasionally when the main TARDIS was incapacitated. The sentient characteristics of the TARDIS have been made more explicit in the spin-off novels and audio plays. In the Big Finish audio play Omega, the Doctor meets a TARDIS which "dies" after its Time Lord master's demise.

Other TARDISes[edit]

The interior of the Rani's TARDIS

Other TARDISes have appeared in the television series. The first was that of the Meddling Monk, another Time Lord, in the 1965 serial The Time Meddler. The Master had at least two TARDISes of his own,[49] each a more advanced model than the Doctor's. The chameleon circuits on these were fully functional, and his TARDISes have been seen in various forms, including a fully functional spacecraft, a Concorde aircraft, a grandfather clock, a computer, a fireplace, a Doric pillar,[50] a lorry, a statue (able to move and walk around), a laurel tree, and an iron maiden. In the reconstructed Shada, the Time Lord known as Professor Chronotis has a TARDIS disguised as his quarters at Cambridge University.

Another renegade Time Lord, the Rani, appears with her TARDIS. In The Armageddon Factor, the Time Lord Drax has a TARDIS, but it is in need of repair. The War Chief provided dimensionally transcendent time machines named SIDRATs[51] to the alien race known as the "War Lords". In the script for The Chase, Dalek time machines are known as DARDISes.[citation needed]

In the spin-off media, Gallifreyan Battle TARDISes have appeared in the comic books, novels and audio plays, which fire "time torpedoes" that freeze the target in time. The renegade Time Lady Iris Wildthyme's own TARDIS was disguised as a No. 22 London bus, but was slightly smaller on the inside than it is on the outside. The Eighth Doctor Adventures novels have stated that future model Type 102 TARDISes will be fully sentient, and able to take on humanoid form.[52] The Eighth Doctor's companion Compassion was the first Type 102 TARDIS,[53] and she was seen to have enough firepower to annihilate other TARDISes.[54] Compassion and other humanoid time-ships appear in the Faction Paradox spin-off material.

The "unofficial" Ninth Doctor from the 40th anniversary animated webcast Scream of the Shalka had a TARDIS console room that looked similar to the Eighth Doctor's version. This console was covered in an array of clock-like dials, featured a long spiral staircase leading far above the console, and connected to a nearby room resembling a Victorian library and study. Due to the freedom afforded by the medium of animation, this TARDIS is the first and only to feature an interior with no walls.

In the Big Finish audio play The One Doctor, confidence trickster Banto Zame impersonated the Doctor. However, due to incomplete information, his copy of the TARDIS (a short range transporter) was called a "Stardis", resembled a portaloo rather than a police box, and was not dimensionally transcendental. In Unregenerate!, the Seventh Doctor and Mel stopped a secret Time Lord project to download TARDIS minds into bodies of various alien species. This would have created living TARDIS pilots loyal to the Time Lords and ensuring that they would have ultimate control over any use of time travel technology by other races. Those created before the project was shut down departed on their own to explore the universe.

Since the destruction of Gallifrey and the Time Lords shown in the 2005 series, the Doctor believes that his TARDIS is the last in the universe.[55] The removal of Gallifrey – and by implication the Eye of Harmony – may also be why the TARDIS in "Boom Town" needed to refuel using radiation from a space-time rift, although the Doctor was able to utilise a "subset of the Eye of Harmony" in the episode "Hide" (2013). In "Rise of the Cybermen" the Doctor states that the TARDIS draws power from "the universe", but is unable to do so while in an alternative reality.

The 28 October 2006 Radio Times, in an image of the Torchwood Three headquarters, identified a piece of large coral on Captain Jack Harkness's desk as the beginnings of a TARDIS. John Barrowman, who plays Jack, said that "Jack's growing a TARDIS... It's probably been there for 30 years. I suppose in 500 years he'll be able to begin the carving process".[citation needed]

In the 2008 Christmas Special edition, "The Next Doctor", Jackson Lake (David Morrissey), while under the delusion that he is the Doctor, has a blue gas balloon which he identifies as his TARDIS, which he explains stands for "Tethered Aerial Release Developed In Style". It is not capable of time travel.

In a deleted scene from the series 4 finale "Journey's End", the Doctor gave a piece of the TARDIS to the half-human Doctor clone so that the latter could grow his own. When the clone remarked that growing a TARDIS would take hundreds of years, Donna Noble provided him with a method of speeding up the process.[56]

In "The Lodger" a vessel, which the Doctor identifies as a somebody's attempt to build a TARDIS, lures in unsuspecting people to pilot its controls, all of whom die due to humans being incompatible with the process. The same interior was used by the Silence in "Day of the Moon" (and the similarity commented on by the Doctor as he enters), but the intended connections between the two are still mostly unknown.

In "The Doctor's Wife", the Doctor and the human avatar of his TARDIS' matrix (aka Idris) view a valley filled with parts of "half-eaten TARDISes", which upsets Idris. Later, the Doctor builds a makeshift TARDIS out of components of the dead TARDISes to be able to save Rory and Amy who are trapped inside his TARDIS, which is now under the control of a malevolent entity. But he still requires energy from Idris in order to make it work. The console used for this episode was designed by the winner of a Blue Peter competition in 2010.

Other appearances[edit]

Spin-offs[edit]

The sound of the Doctor's TARDIS featured in the final scene of the Torchwood episode "End of Days". As Torchwood Three's hub is situated at a rift of temporal energy, the Doctor often appears on Roald Dahl Plass directly above it in order to recharge the TARDIS. In the episode, Jack Harkness hears the tell-tale sound of the engines, smiles and afterwards is nowhere to be found; the scene picks up in the cold open of the Doctor Who episode "Utopia" in which Jack runs to and holds onto the TARDIS just before it disappears.

Former and recurring companion, Sarah Jane Smith, has a diagram of the TARDIS in her attic, as shown in The Sarah Jane Adventures episode "Invasion of the Bane". In the episode The Temptation of Sarah Jane Smith, Sarah Jane becomes trapped in 1951 and briefly mistakes an actual police public call box for the Doctor's TARDIS (the moment is even heralded by the Doctor's musical cue, frequently used in the revived series). It makes a full appearance in The Wedding of Sarah Jane Smith, in which the Doctor briefly welcomes Sarah Jane's three adolescent companions into the control room. It then serves as a backdrop for the farewell scene between Sarah Jane and the Tenth Doctor, which echoed nearly word-for-word her final exchange with the Fourth Doctor aboard the TARDIS in 1976. During the Eleventh Doctor era it reappears in Death of the Doctor, is stolen by the Shansheeth who try to use it as an immortality machine, and transports Sarah Jane, Jo Grant and their adolescent companions (Rani Chandra, Clyde Langer and Santiago Jones).

Merchandising[edit]

As one of the most recognisable images connected with Doctor Who, the TARDIS has appeared on numerous items of merchandise associated with the programme. TARDIS scale models of various sizes have been manufactured to accompany other Doctor Who dolls and action figures, some with sound effects included. Fan-built full-size models of the police box are also common. There have been TARDIS-shaped video games, play tents for children, toy boxes, cookie jars, book ends, key chains, and even a police-box-shaped bottle for a TARDIS bubble bath. The 1993 VHS release of The Trial of a Time Lord was contained in a special-edition tin shaped like the TARDIS.

With the 2005 series revival, a variety of TARDIS-shaped merchandise has been produced, including a TARDIS coin box, TARDIS figure toy set, a TARDIS that detects the ring signal from a mobile phone and flashes when an incoming call is detected, TARDIS-shaped wardrobes and DVD cabinets, and a USB hub in the shape of the TARDIS.[57] The complete 2005 season DVD box set, released in November 2005, was issued in packaging that resembled the TARDIS.

One of the original-model TARDISes used in the television series' production in the 1970s was sold at auction in December 2005 for £10,800.[58]

In popular culture[edit]

Footnotes[edit]

Notes
  1. ^ Generally, TARDIS is written in all upper case letters—this convention was popularised by the Target novelisations of the 1970s. However, the use of Tardis is equally correct and consistent with current British press style, in which acronyms which form a pronounceable word are spelled with only the first letter capitalised (for example, Bafta), while acronyms requiring each letter to be read out (also known as "initialisms") are capitalised in their entirety (for example, BBC). Many examples of the form Tardis are found in media and, occasionally, licensed publications (in the 2005 series episode "World War Three", the caller ID of the TARDIS is displayed on Rose Tyler's mobile phone as "Tardis calling"—this capitalisation of only the initial letter being the default setting for Nokia mobile phones). The OED has the word "Tardis" capitalised as such with a first appearance from the Times in 1969. ("Tardis, n.". Oxford English Dictionary. June 2002. "His best poems are like Doctor Who's Tardis, the solid streetcorner policebox, which actually contains a sidereal spaceship." )
  2. ^ There is some disagreement over whether the "D" in the name stands for "dimension" or "dimensions"; both have been used in various episodes. The very first story, An Unearthly Child (1963), used the singular "Dimension" and other episodes followed suit for the next couple of years. The 1964 novelisation Doctor Who in an Exciting Adventure with the Daleks used the plural "Dimensions" for the first time and the 1965 serial The Time Meddler (1965) introduced it to the television series. Since then both versions have been used on different occasions; for example, it is singular again when mentioned in Frontios (1984). In "Rose" (2005), the Doctor uses the singular form (although this was a decision of the actor Christopher Eccleston—the line was scripted in the plural). Likewise, the Tenth Doctor keeps the word firmly singular in "Smith and Jones" (2007). The plaque set on the TARDIS console in the current design also uses the singular form. The 2011 episode "The Doctor's Wife" further establishes the singular as definitive by having the TARDIS herself use "Dimension" when uttering the full meaning of the acronym.
  3. ^ In the two 1960s Dalek films, the craft was referred to as Tardis, without the definite article.
  4. ^ Steven Moffat confirmed that this line was an in-joke aimed at the Outpost Gallifrey forum.
  5. ^ The Sixth Doctor states this in The Two Doctors (1985). However, the Doctor later states that he had made some things up to confuse the Sontarans, who were trying to duplicate the Imprimatur to prime their own time vessel.
