The first ever episode of Star Trek went to air in 1966, three years before humans set foot on the moon.
Since then it's grown into a pop culture behemoth, spawning TV incarnations, movies, video games and of course, merchandise - it is now a 10-billion-dollar brand!
It's also inspired generations of impassioned fans - you might know them as Trekkies, and today we welcome Ross Stevenson, Star Trek expert, who has an entire room in his Temuka home devoted to all things Star Trek.
