The Moonbase (TV story)

The Moonbase was the partly-missing sixth story of Season 4 of Doctor Who. It saw the reappearance and first redesign of the Cybermen, solidifying their place as one of the series' key villains. This story was the first in Doctor Who history with sequences taking place on Earth's Moon.

Synopsis
The TARDIS arrives in 2070 on the Moon, where a weather control station under the command of a man named Hobson is in the grip of a plague epidemic — in reality the result of an alien poison planted by the Cybermen. Jamie is knocked unconscious and lapses into a delirium, leaving the Second Doctor, Ben, and Polly to fight off a massive Cyberman attack.

Episode one
The TARDIS makes a bumpy landing on the moon in the year 2070. They go outside in spacesuits and Jamie is injured when they fool around. They discover the Moonbase — a weather control station that keeps Earth's weather in check. It is staffed by international crew under Hobson, the controller. They are using a gravity machine called the gravitron to control the weather. The Doctor investigates a mystery: patients have collapsed in comas and have been infected by a virus. All victims are confined to the sickbay. Jamie is put in the medical wing until his fever subsides. International Space Control responds to the crisis by quarantining the Moonbase, a precaution made more valid as a patient starts to die. Soon a crew member disappears in the food stores without a trace. Jamie, delirious, begins to mumble about the phantom piper, his clan's variant of the Grim Reaper. A Cyberman appears in the medical wing.

Episode two
Polly witnesses the Cyberman abducting a patient. She informs the Doctor and the others, but Hobson does not believe her due to lack of evidence. Hobson soon notices the Moonbase's radio transmissions are being monitored. More people are infected by the virus and the Cybermen abduct them all. The Doctor soon works out the Cybermen have infected the sugar in the food stores to make the virus spread, thus explaining the virus' seemingly random attack pattern — depending on the crew's preference for sugar in their food or drink. They contact base but the radio transmissions are blocked. The Doctor informs Hobson that the Cybermen are definitely on the Moonbase and asks if the men have searched everywhere. After Hobson informs them they have checked everywhere apart from the medical wing, a Cyberman appears from one of the medical wing beds and advances towards them.

Episode three
Bob, a crew member, is killed. The Cybermen contact the Cyber fleet. The leader reveals the dead crew members have been augmented and are under Cyber control. More Cybermen emerge from hiding and take over central control. They intend to use the gravitron to destroy life on Earth and send Doctor Evans, the first victim, to operate it. Ben, Polly and Jamie (now recovered) use a cocktail of certain types of chemicals, each of which attacks a certain type of plastic, to dissolve the Cybermen's chest units. The fleet land and deploy reinforcements, which advance in force across the lunar surface toward the Moonbase.

Episode four
The Cybermen destroy a relief craft and use radio controlled beams to reactivate the augmented crew members, who walk around the Moonbase killing multiple people. They are soon killed by the crew, but their relief rocket has been thrown into the Sun. The Cyberleader threatens that if the resistance continues they will fire, demonstrating by making the base lose oxygen by punching a hole in it. They use a large cannon to fire shots at the Moonbase, which are deflected by the gravitron. The Doctor aims the gravitron at the surface and the Cybermen and fleet are cast off into space. Hobson repairs the gravitron and the Doctor and his companions slip away. Back aboard the TARDIS, the Doctor decides to consult a device called the time scanner, which can give glimpses of the future. An image of a large crab-like claw then appears on the scanner screen...

 * The Cybermen can utter electricity out of their hands.

Earth technology

 * The Moonbase was established around 2050 to control the Earth's weather via the Gravitron.
 * The Gravitron runs on thermonuclear power and manipulates gravity.

Foods and beverages

 * The virus is in the sugar.
 * Polly serves coffee and tea.
 * Milk is needed on the base.

Places

 * When the Gravitron goes out of alignment, hurricanes threaten Hawaii first, then Miami.

Planets

 * The Moonbase is on the Moon.

References to popular culture

 * Hobson calls the Doctor a "proper Rip Van Winkle".
 * While jumping on the Moon, Polly jokes about Ben having had ballet lessons.
 * Jamie mistakes a Cyberman for a piper phantom of his Scottish culture.

Science

 * The Cybermen shoot a hole in the Moonbase, making it lose oxygen.
 * The Cybermen's chest unit appears to be made of a kind of plastic. Ben and Polly make up a mixture with different solvents (acetone, benzene, ether, alcohol and propane) in order to affect it.
 * Ben is quite knowledgeable about certain things on the moonbase. He knows that the Gravitron uses thermonuclear power, that interferon is a viral antibody, that acetone is present in nail varnish remover and that the spray from the fire extinguishers would evaporate in a vacuum.
 * The Cybermen infect the scientists with the large neurotropic virus named Neurotrope X, visible with the microscope in the medical unit of the base.
 * The scientists would like to call for help through a distress rocket made of sodium, that burns in the sunlight.

TARDIS

 * The Doctor suggestes that the TARDIS is a sterile craft.
 * A chest in the TARDIS provides space suits for the Doctor and his companions.
 * The TARDIS has a time scanner, rarely used by the Doctor, able to give a glimpse of the future.

The Doctor

 * The Doctor mentions that he studied medicine under Lister in Glasgow in 1888.

Story notes

 * This story had the working title Return of the Cybermen.
 * The final clip of the episode leads into The Macra Terror.
 * In an early edit of the script, the Cybermen had names.
 * Talkback from the headphones of the crew on the studio floor is clearly audible at times during episode four (the same problem as had earlier caused the opening episode of The Daleks to have to be remounted) — for example, a voice can be clearly heard saying "Cue" at the start of the scene where the controlled scientists are first activated by the Cybermen.
 * Alan Rowe is credited as 'Voice from Space Control' and 'Dr. Evans' (separate on-screen captions) for episodes one and three, only as 'Voice from Space Control' for episode two and only as 'Dr. Evans' for episode four. He is billed as 'Voice from Space Control/Dr. Evans' in Radio Times for episode three.
 * All of the actors playing the scientists were credited without specific roles under the heading 'Others in Cast' in Radio Times.
 * Mark Heath is credited as 'Ralph' for episode one, and as 'Scientist' for episode three. He is billed without specific role under the heading 'Others in Cast' in Radio Times for episode three.
 * John Wills and Sonnie Willis, playing Cybermen, are credited without specific role under the heading 'Others in Cast' in Radio Times for episode one.

Production errors

 * In episode two, when a Cyberman tries to zap Polly while she tends to Jamie in the sick bay, he misses, but she falls anyway.
 * Hobson notes they need to keep a hurricane in the Pacific Ocean. However, the Gravitron is pointed at the Atlantic and the hurricane is threatening Miami.
 * Close-ups of the transparent dome from the outside only show the Gravitron, not any of the desks, controls, people etc.
 * The examination tables in the sick bay are very light and wobble frequently. The most obvious cases are when the Cyberman takes one of the crew off one and later when he hops up off the table, almost knocking it over completely.
 * When Evans sneaks into the Gravitron control room, he puts the cloth helmet on back to front (in the next scene it's the right way round).
 * When the Cybermen's spaceships land, the wires holding them are clearly visible.

Continuity

 * International Space Command previously appeared in TV: The Tenth Planet.
 * The Cybermen shoot energy from their hands. (TV: The Tomb of the Cybermen and Rise of the Cybermen)
 * The Cybermen would make use of viruses and biological agents in TV: Revenge of the Cybermen.
