Now, don't confuse the space shuttle Enterprise with the Starship U.S.S. Enterprise. Only one of those vehicles ever went to space--and it was the fictional one.
The NASA orbiter OV-101, unlike the Star Trek ship for which it was named, never did make a trip to space. But it was the first of six shuttles built--actually a prototype incapable of spaceflight--and completed crucial tests that helped lead the way for the five shuttles that followed.
It was the floated on a barge around Manhattan, ultimately making its way to the aircraft carrier-turned-museum Intrepid, where it is now available for public viewing.
The Intrepid is celebrating its newest arrival with a five-day SpaceFest on the carrier's flight deck.
