The Ark in Space (TV story)

Synopsis
The TARDIS arrives on an apparently deserted and deactivated space station Nerva, otherwise known as the Ark, orbiting Earth in the far future. There the Doctor, Sarah and Harry discover the last survivors of the human race held in suspended animation, Earth having been evacuated thousands of years earlier when solar flares threatened to destroy all life.

The station has been visited by a Wirrn, an insect life form, which has laid its eggs in the solar stacks and absorbed the body and mind of one of the sleeping humans. The Doctor's reactivation of the station's systems causes the humans to start to revive. Their leader, nicknamed Noah, becomes infected by one of the emerging larvae and is slowly taken over.

The Doctor and his friends meanwhile gain the trust of the other humans, now led by a med-tech named Vira. Together they manage to lure the hatched Wirrn insects into a shuttle craft and then eject it into space.

In a final act of humanity, Noah - by this time fully transformed into a Wirrn - deliberately neglects to set the shuttle's stabilisers, causing it to explode.

Part one
An unseen presence approaches a space station orbiting Earth and silently infiltrates it until it reaches a human apparently asleep and unaware...

The TARDIS materialises in a dark and stuffy room aboard an apparently unmanned station, due to Harry's inadvertent interference with the helmic regulator. Once the Doctor turns the lights on, the TARDIS crew decide to look round. Harry presses another switch, unknowingly trapping Sarah in a small control room where the oxygen is rapidly being consumed. By the time the Doctor and Harry find her she is severely cyanosed, but they then find themselves trapped with her. The Doctor manages to repair the oxygen servos just in time to save them all, noticing that the control cables had been bitten clean through. As sarah recovers on a nearby couch, the Doctor and Harry are attacked by an Automatic sentry system which fires electronic bolts at any organic object that moves. Meanwhile Sarah is transported from the couch into a chamber where she hears two voices preparing her for a "journey". The Doctor and Harry manage to deactivate the auto guard and discover that Sarah has vanished. Exploring further into the station they encounter a slime trail in the corridor, but continue into a restricted section containing hundreds of cryogenically suspended humans, along with animal and botanical specimens and an information store. Harry opens one berth and finds Sarah in suspension. He begins looking for a resuscitation unit to revive her and opens a cupboard - only to encounter a giant insect which looms toward him...

Discontinuity, Plot Holes, Errors

 * If there are thousands of people on Nerva, why is there only 1 shuttle and a transmat with only 3 pads? The Shuttle may be larger than what we see and there are probably more transmat pads throughout the station. Vira does say that getting everyone down to Earth via transmat will be a long task.
 * Why do they teleport to the Earth rather than take the Tardis? The TARDIS can be unreliable at times.
 * There is a piece of very poor editing done when the half-mutated Noah confronts Vira and the Doctor as they move along the corridor (probably done to remove the more grotesque aspect of the scene). Noah is stil talking and then somehow the door slams shut, cutting him off. Yet it is not clear who does this or what exactly happened.
 * The people needed to use a device on their hearts to complete the revival - how would this have worked if no-one was around to help them with it?  It's not part of standard procedure; the system had already malfunctioned due to the Wirrn's interference.
 * The Wirn falling out at the first cliffhanger interupts the Doctor talking - but he's not talking at the start of episode 2. Or we just don't hear him.

Continuity

 * The Ark in Space is part of a set concerning Nerva Beacon without TARDIS travel; beginning in The Ark in Space and continuing through DW: The Sontaran Experiment, Genesis of the Daleks, MA: A Device of Death and then ending in DW: Revenge of the Cybermen set back aboard Nerva beacon at an earlier point in time.


 * EDA: Placebo Effect features the Wirrrn and delves further into their history and psychology.


 * BFA: Wirrn Dawn is set during the war between the Humans and the Wirrn.
