Star Trek It has been suggested that the quote was taken from a White House booklet published in 1958. The Introduction to Outer Space, produced in an effort to garner support for a national space program in the wake of the Sputnik flight, read on its first page:
The first of these factors is the compelling urge of man to explore and to discover, the thrust of curiosity that leads men to try to go where no one has gone before. Most of the surface of the earth has now been explored and men now turn on the exploration of outer space as their next objective.
Interestingly, the situation came full circle in 1989, when NASA used the Star Trek version of the quote to title their retrospective of Project Apollo: Where No Man Has Gone Before: A History of Apollo Lunar Exploration Missions.
The phrase was first introduced into Star Trek by Samuel Peeples, who is attributed with suggesting using it as an episode name. The episode became "Where No Man Has Gone Before", the second pilot of Star Trek. The phrase itself was subsequently worked into the show's opening narration, which was written after the episode. Indeed, the introductory sequence was devised in August 1966, after several episodes had been filmed, and shortly before the series was due to debut. It is the result of the combined input of several people, including Star Trek creator Gene Roddenberry and producers John D. F. Black and Bob Justman.
