Search Out Space (TV story)

Search Out Space was a special crossover episode between Search Out Science, a children's education programme, and Doctor Who that aired on BBC Two in 1990. It was written by Lambros Atteshlis and Berry-Anne Billingsley and also directed by the latter.

Sylvester McCoy reprised his role as Seventh Doctor thus this story served as an extension of his time as the incumbent Doctor. Sophie Aldred also reprised her role as Ace. John Leeson provided the voice of K9 for the first time since The Five Doctors. Notably this was the first on screen story since Survival and thus the first on screen story released during the "wilderness years"

Despite an apparently fourth-wall-breaking setup, the story would contextualise this as the Doctor taking part on an in-universe quiz show. It was further placed in regular Doctor Who continuity by the short story Storm in a Tikka. The latter links it to Dimensions in Time, also aired during McCoy's time as the incumbent Doctor, which had the TARDIS team of Ace and K9 also.

The story also marks the final on screen usage of the Keff McCulloch Doctor Who theme used since Time and the Rani in 1987.

Synopsis
The Doctor, Ace, K9 and Cedric are taking part in a game show to see who can win The Ultimate Challenge - the biggest gameshow in the universe.

The contestants are forced to answer fairly basic questions about space, with severe punishments if they get it wrong.

Plot
The Doctor runs on stepping stones lying in space and runs across them. He then jumps onto his hovering platform. The Doctor tells his audience they've been selected to take part in The Ultimate Challenge. The Doctor acts as host. He then announces the fellow challengers which are his companion Ace, from Earth, Cedric from Quirk and former companion K9 said to be renowned for his superior powers of logic.

The Doctor then presents the first question to Cedric. He has thirty seconds to answer. What shape is the Earth? The Doctor tells the audience if they want to join in they can watch Cedric try and guess. Cedric materialises on a picnic table outside an Earth pub. He says he’s not from this planet, but thinks he knows the answer. Beside him on the table are three models of Earth in different sizes. Those sizes being round, flat and square. He then wants some more evidence before he makes his guess.

Just above Cedric. In the sky the TARDIS materialises. K9 claims to be up there in space, despite not being in space. From a computer room in the TARDIS K9 flies the ship and sends Cedric a clue. Cedric is sent a picture of the Earth, but sadly the picture doesn’t help him determine if it’s a sphere or a circle.

Ace, in a tree, then aids the audience and Cedric with a clue as she stares into the distance with paper rolled to be a telescope ish thing. She says if someone stranded on a desert island saw a ship on the horizon would they see the ship itself or the top of the mast first. The paper then teleports from Ace’s hand into Cedric’s. Cedric then unrolls the paper to see a drawing of the horizon with a boat present. He says it’s as he thought. The Doctor then says he’s got all the clues can he solve the challenge. Cedric then pulls out a cylindrical shaped Earth say it’s that size. This is followed by a wrong answer buzzer sound. He realises he's wrong and doesn't understand why. The Doctor says it's a perfect challenge for his audience to figure why Cedric was wrong.

The Doctor then hurries things along as he floats in the Earth's orbit. He then challenges everyone to answer what makes day and night. Cedric is then in a tunnel experiment room flashing a torch at a model of the Earth while repeating "day time" and "night time" then address the audience as ladies, gentlemen and aliens. He then spins the Earth model.

Eventually, Ace deduces that there is no answer to one of the questions. The Doctor says this is the right answer, and bizarrely produces an ice cream as if by magic.
