"Something hidden. Go and find it.
Go and look behind the Ranges —
Something lost behind the Ranges.
Lost and waiting for you. Go!"
— "The Explorer", Rudyard Kipling
"Space: the final frontier. These are the voyages of the starship Enterprise. Its continuing mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no one has gone before."
"They used to say if man could fly, he'd have wings... but he did fly. He discovered he had to. Do you wish that the first Apollo mission hadn't reached the moon, or that we hadn't gone on to Mars or the nearest star? That's like saying you wish that you still operated with scalpels and sewed your patients up with catgut like your great-great-great-great-grandfather used to. I'm in command. I could order this. But I'm not … because … Dr. McCoy is right in pointing out the enormous danger potential in any contact with life and intelligence as fantastically advanced as this. But I must point out that the possibilities, the potential for knowledge and advancement is equally great. Risk ... risk is our business! That's what this starship is all about ... that's why we're aboard her!"
— Captain James T. Kirk, Star Trek episode "Return to Tomorrow"
