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