The Impossible Planet was the eighth episode of the second series of Doctor Who. It marked the first appearance of the Ood.

Synopsis

Rose finds herself further away from home than ever before, on a space base positioned on a planet in the orbit of a black hole. Meanwhile, an unknown entity is awakening and beginning to cause chaos amongst the crew.

Plot

The TARDIS materialises inside a "Sanctuary Base" meant for deep-space expeditions. The Tenth Doctor and Rose discover an inscription scribbled on the station wall which the TARDIS is unable to translate.

After a slight misunderstanding when first meeting the Ood, a docile race of empathic servants who work on the station, the travellers meet the crew of the base, led by acting Captain Zachary Cross Flane. Then an earthquake occurs and they all have to take cover. Afterwards, the crew is introduced to Science Officer Ida Scott, Head of Security John Jefferson, trainee maintenance officer Scooti Manista, and archaeologist Toby Zed. They are on an expedition on an anomalous planet in orbit around a black hole, K37 Gem 5. The Doctor realises that it is impossible for the planet, which is called Krop Tor, to be in geostationary orbit around the black hole, as it should be pulled in like the star systems around it are. He calculates that it would take a phenomenal amount of power (six to the power of six for six seconds) to generate the huge gravity funnel stabilising its orbit. The funnel is not a natural phenomenon, and the crew is drilling ten miles underground to the core of the planet in hopes of finding the power source and using it. The origin of the power source is an ancient civilisation that had been on Krop Tor, and the inscription on the wall is a transcription of a stone tablet found on the planet.

The Doctor soon discovers that storage sections 5 to 8 had collapsed as a result of the earthquake-like tremor they had experienced moments after their arrival, dropping the TARDIS, which had been in Storage 6, into a crevasse. With no resources to divert the drilling, Rose and the Doctor are stranded.

Toby is possessed by the Beast.

It isn't long before a malevolent presence begins to make itself known. Strange messages about the Beast awaking to make war against God emanate from the Ood's translation spheres and the base computer's speakers. Toby begins to hear voices just before he is possessed by the Beast. Then the crew and travellers watch as the Scarlet system is swallowed by the black hole. Rose receives a strange message on her phone and Toby wakes up. Danny, the Doctor, and Rose all discover the Ood acting up and saying strange things.

The Beast kills Scooti.

Meanwhile, Scooti goes to Toby's room to drop off paperwork, but finds his room empty. While she puts the paperwork on the desk, the computer announces the opening and closing of Door 41, puzzling her. Concerned, she leaves Toby's room in a rush and enters the section with Door 41, which is the airlock. The computer confirms that the door opened and closed, but cannot tell who went outside. Scooti then asks whose spacesuit was logged out, but it says no spacesuit was taken. Scooti tries to call Zach, but her wrist radio fizzles and dies; the computer can find no problem with it. Furious, Scooti demands that the computer tell her who went outside, but it says, "He is awake". When she asks what that means, it responds with, "He who bathes in the black sun". Out of the viewport, Scooti, to her shock, sees Toby on the barren planet's surface, somehow surviving without a spacesuit. Toby turns, grinning evilly at her, and gestures her towards him. Scooti falls under the Beast's influence and begins to move towards Toby, but soon manages to shrug off his control. Scooti is left shaken to the core and pleads for him to stop. Toby, angered by her refusal, clenches his fist. Sounds of glass breaking fill the corridor, and soon a crack appears on the window. Scooti gasps in fear upon realizing his intent and turns from the window. Frightened, she runs towards Door 40 and tries to open it. Scooti's panic turns to horror as Door 40 refuses to open despite her desperate attempts to open it. Soon, Toby shatters the glass, and air begins rushing out the base. Scooti is violently dragged away from the door and pulled out into the vacuum of space, screaming in horror.

The base begins to shake violently and Zach orders them to evacuate. Danny, Rose, and the Doctor race to meet Jefferson, Ida, the security guards, and the now unpossessed Toby get through the door. Jefferson then closes the door, sealing the breach. Zach then asks if everyone was all right. Jefferson then reports that everyone is there except Scooti. Jefferson then calls for Scooti on his radio. However, he gets no answer. Zach then tells them she is alright and that her biochip located her in Habitation 3. Jefferson and Ida sigh in relief. They then go down to search for Scooti while the Doctor and Rose tend to Toby.

Scooti is dead.

When Toby, Rose, and the Doctor enter the habitation they find the searchers looking frantically. Ida is calling all the habitations looking for Scooti. Jefferson then reports that Scooti is still missing while Zach continues by saying that her biochip says she is in Habitation 3. Then the Doctor sadly says he found her. Scooti was floating outside with her hair flying and her skin pale. Jefferson reports her death while Zach looks sorrowful. Ida then goes over to the control to close the overhead saying how she was only twenty years old. Scooti floats away towards the black hole spinning as the door closes. Jefferson recites a verse from "Horatius," a poem by Thomas Babbington Macaulay: "And how can man die better/ Than facing fearful odds/ For the ashes of his fathers,/ And the temples of his gods."

The team finally manages to drill down to the core of the planet. The Doctor and Ida journey down the mine shaft and into a massive cavern with ancient giant sculptures along its walls. They head for the power source, guided by sensor readings, and find a large circular disk set in the floor of the cavern, which the Doctor suspects is a trap door of some sort. The edge of the disk is also covered with inscriptions.

The pit opens.

Meanwhile in the base, the Ood's telepathic field rises dangerously to Basic 100, which is high enough to induce brain death, but they are obviously still alive. Finally the beast makes itself known through Toby before seemingly transferring itself to the Ood. The Ood identify themselves as the Legion of the Beast and begin to advance on the crew members, including Rose. Finally, the Doctor and Ida stand before a seal on the cavern ground, which then slides open to show a black chasm. A voice calls out from beneath it, stating, "The pit is open, and I am free!". As the Doctor and Ida look down, malevolent laughter echoes from below...

References

• The Scarlet System was home to the Pallushi, a mighty civilisation that spanned a billion years.
• The scriptures of the Veltino describe the planet as Krop Tor - "the bitter pill".
• The Doctor states TARDISes are grown, rather than built.
• When Ida mentions, "There's no turning back", the Doctor says it is almost as bad as saying, "This is going to be the best Christmas Walford has ever seen", a reference to EastEnders and their infamously miserable holiday specials.
• Jefferson quotes Thomas Babington Macaulay's poem Horatius: "And how can man die better, than facing fearful odds, for the ashes of his fathers, and the temples of his Gods?"
• During the night shift, the base plays Maurice Ravel's Bolero.
• The episode references the number 42 twice: it is set in the 42nd century, and the hallway containing Door 14 is numbered 42. In Series 3, another episode set in the 42nd century would be broadcast, which was called 42.
• The Doctor states that to generate a force field to resist the black hole's pull would require a power source with an inverted self extrapolating reflex of "six to the power of six every six seconds. Coincidentally, "666" is referred to as "the number of the Beast".
• The funnel-shaped gravity field at the bottom of which the Doctor finds Lucifer is a reference to Dante's Inferno, in which hell also takes shape of a funnel with the devil at bottom of it.

Story notes

• Gabriel Woolf previously played (and voiced) Sutekh in Pyramids of Mars.
• This is the first episode of the revived series not to have any scenes take place on or within orbit of Earth.
• Sound effects matching the door opening and closing sounds from the first two games in the the popular Doom series are occasionally used (especially noticeable when Toby goes searching for the "voices" distracting him from his archaeological findings).
• The Doctor calculated that the power needed was six to the power of six every six seconds, a reference to 666, the supposed number of the Beast as mentioned in the Biblical book of Revelation.
• Before the Ood, the production team had considered Raxacoricofallapatorians being the servants on Sanctuary Base 6, but it was decided to use a new race when it emerged that the cost of repairing the Slitheen costumes was just as much as if the crew created new aliens from scratch.
• The Ood would be later revealed in Planet of the Ood to come from a region of space near the Sense Sphere, thus suggesting a genetic relationship between them and the Sensorites. Interestingly, the Sensorites are introduced in "Strangers in Space" in a very similar way to how the Ood are in this episode. Both races at first appear to threaten the Doctor and his companions before they finally reveal their more benign intent.

• When the Doctor and Ida descend into the core of Krop Tor, the screen charting their progress shows 39% oxygen. After cutting away to an overhead shot of the two, the camera cuts back to the same descent display, only now the oxygen percentage (which has been falling constantly all this time) is at 42%.

Continuity

• A similar devil-like creature appears in TW: End of Days.
• Rose mentions her experience as a dinner lady in DW: School Reunion.
• The Ood, while possessed by The Beast, say "I shall become the manifest," as does The Wire in DW: The Idiot's Lantern.
• Rose receives a message on her phone, however, two episodes ago, in "The Age of Steel," Rose gave her phone, that contained the code to the Cybermen's emotional inhibitors, to Mickey Smith while in a parellel universe.

Timeline

• This story occurs after DWA: Warfreekz!.
• This story occurs before DW: The Satan Pit.

International broadcast

When aired by the Canadian Broadcasting Corporation in late 2006, this episode was considered a mid-season cliffhanger, with The Satan Pit and the rest of the season not airing until early 2007, after a hiatus of several months. At the time the CBC made this decision a trend had developed among North American networks to insert lengthy (sometimes months-long) breaks during the November-January period.
