September 8, 1966 — The first “Star Trek” episode is broadcast

Space: the final frontier.
These are the voyages of the starship Enterprise. Its five-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.

With these words, one of the greatest science fiction franchises of all time was inaugurated. “Star Trek” may have had its flaws, but its vision of a future in which all sentients of good will worked for the common good was an appealing one. From the humble beginnings of a first season that was still trying to figure out what it was, “Star Trek” grew to become a media behemoth, made the people who acted in it stars of the screen, and exerted a great influence over our culture.

As Spock might put it, it lived long and prospered.

November 20, 2265 – The starship Enterprise begins its five year mission

Space… the final frontier.
These are the voyages of the starship Enterprise.
Its five year mission:
to explore strange new worlds,
to seek out new life and new civilisations,
to boldly go where no man has gone before…

Today is the day that it all will have started (time travel weirds English ever worse than verbing), in the year 2265. Kirk, Spock, McCoy, Uhura, Sulu and Scotty started their five year mission, of which, alas, only the first three years were shown on television. (Chekov joined the crew later.)

The first episode of Star Trek was “The Man Trap”, and the date used here is derived from the stardate given in that episode.
