The Space Shuttle Enterprise was NASA’s first orbiter Space Shuttle system, built to perform atmospheric test flights after being launched from a Boeing 747. The shuttle had no engines
and was therefore not capable of space flight. Construction of Enterprise began on 4 June 1974 and it was unveiled at Rockwell’s
plant at Palmdale, California, on 17 September 1976. Originally the shuttle was to be named Constitution, but a letter-writing campaign by Star Trek fans to President Gerald Ford, was successful in the name being changed to Enterprise. Enterprise
made its maiden flight on top of a Boeing 747 Shuttle Carrier, on 18 February 1977 and flew on its own for the first time on 12 August 1977.
