TheSpace ShuttleEnterprise (OV-101) was the first orbiter built in theSpace Shuttle program. Designed for atmospheric test flights, it lacked both engines and a heat shield, making it unable to go to space. Rolled out on 17 September 1976, it was initially namedConstitution, but was renamed following a large letter-writing campaign fromTrekkies. Unlike itseponym, theUSSEnterprise from theoriginalStar Trek series, OV-101 never achieved spaceflight; originally intended to berefitted to become the second space-rated orbiter afterColumbia, changes to the design of the Space Shuttle made it both simpler and cheaper to instead construct a new shuttle,Challenger, around atest article. It was later considered for refitting following theChallenger disaster, but it was instead decided to build a replacement,Endeavour, out of spare parts from the construction ofDiscovery andAtlantis.

Enterprise flew a total of five times, from 12 August to 26 October, 1977. It was then flown toMarshall Space Flight Center inAlabama, where it was placed into theSaturn V dynamic test stand for the Mated Vertical Ground Vibration Testing, in order to test the Space Shuttle's launch stack. It was then used for a variety of fit checks atKennedy Space Center andVandenberg Air Force Base, between which it toured Europe and North America, including a showing at the1984 Louisiana World Exposition. It was then moved to theSmithsonian Institution'sNational Air and Space Museum on 18 November 1985. It was then moved to its present location aboard theUSSIntrepid museum ship on 12 December 2011.
