An inquiry room located inside the Space Exploration Centre.

The Martian Exploration Center is a space exploration center featured in the movie Thunderbirds Are Go. It is located at a place called Cape Johnson.

The building itself never appears during the film; we only get to see an inquiry room inside.

Inquiry Room

The inquiry room was a room used for inquiries and votes, such as the discussion about the Zero X crash and whether people were for or against an idea.

The room was tangerine and black in colour and had at least 14 seats at the long table.

  • It was Sylvia Anderson's idea to have the inquiry room set only tangerine and black in colour. She could tell that art director Bob Bell wasn't keen on this, but as a producer, Sylvia was in charge, so Bob did as she asked.
  • The Supermarionation team had to get a crane inside the studio so they could film the whole inquiry room set.
  • Part of the floor was used again in the episode Alias Mr. Hackenbacker.
  • The set reportedly weighed two tonnes.[1]

  • For unknown reasons, 2 of the board members were played by different puppets in the overhead shots. No. 8 Brad Newman was played by the Bill Craddock puppet, and no. 11 was played by the Lieutenant Burroughs puppet. (These 2 puppets are also seen at The Swinging Star later in the film.)
