James T. Kirk Going Into Space

William Shatner is among the 7,000+ who have already declared their willingness to pay for a ride on Virgin Galactic's spaceship.

Although there are many other notable personalities already on the list, there's a certain poetic justice to seeing Shatner actually do what he has been pretending to do all these years. Particularly when you consider that this may never have happened if he hadn't inspired so many to reach for the stars with his work on Star Trek.
