Space Shuttle Enterprise was the first ever shuttle to be constructed. It never made it into space, it was used purely for atmospheric test flights, but Enterprise was a significant craft. Originally NASA planned to designate the shuttle Constitution, but after a a sustained write-in campaign, NASA changed its name in honour of the Starship Enterprise from the original series of Star Trek. In 1976, the USS Enterprise (NCC-1701) was being captained by Captain Kirk (played by William Shatner), and some of the original series actors were at the roll-out ceremony in Palmdale manufacturing facility in California.
In the picture above, from left to right: Dr. James D. Fletcher, NASA Administrator, DeForest Kelley (Dr. “Bones” McCoy), George Takei (Mr. Sulu), James Doohan (Chief Engineer Montgomery “Scotty” Scott), Nichelle Nichols (Lt. Uhura), Leonard Nimoy (Mr. Spock), Gene Roddenberry (producer and creator of Star Trek), and Walter Koenig (Ensign Pavel Chekov).
A wonderful scene capturing the beginning of 32 years of shuttle operations. This is an especially poignant image as Star Trek creator Gene Rodenberry and two of the original Star Trek cast, DeForest Kelley and James Doohan have since passed away.
