Insurrection. Designer Andrew Probert came up with the concept of the captain's yacht while designing the USS Enterprise-D. Although it was never seen in use, it is labeled on the master systems display screen in main engineering, docked at the bottom of the saucer section almost directly opposite the main bridge. Probert suggested possible ways for the yacht to be used during the first season, including not showing the yacht but mentioning it in dialogue, but his ideas were rejected. The producers almost used the yacht in the episode "Samaritan Snare", but decided to use an "executive shuttlecraft" due to budgetary constraints. According to Patrick Stewart, the yacht would have been called the Calypso. Producer Ronald D. Moore noted in the Star Trek: The Next Generation Technical Manual that real-life naval tradition would insist on calling such a craft the captain's gig, rather than the captain's yacht. Rick Sternbach later designed similar craft for USS Voyager and USS Equinox, known as the aeroshuttle and the waverider, respectively. As on the Enterprise-D, however, these vessels were only depicted on technical schematics and never seen in operation or referred to in dialog. Reception and influence Gizmodo's Io9 blog ranked the original design of the as the best version of the Enterprise, characterizing the original as still superior to 11 later versions of the Enterprise that had appeared in the Star Trek franchise. By contrast, in 2019, SyFy ranked the refit design of the Enterprise (NCC-1701 and NCC-1701-A) as the franchise's best, ranking the original design as only the fourth best version of the starship. Time described each iteration of the Enterprise as "a character in its own right". Over many decades, the starship has influenced real-life activities of NASA and the U.S. Navy: In 1976, as the result of a successful letter writing campaign by fans, NASA named the initial flight-test Space Shuttle Enterprise. However, the shuttle itself was never intended to fly in space, to be used only for initial atmospheric flight tests. For three days in October 1994, the aircraft carrier hosted half-hour tours for thousands of fans attending a Star Trek convention in Norfolk, Virginia, and Star Trek memorabilia could be found throughout the ship. In 2014, NASA named its IXS Enterprise advanced propulsion concept vehicle after the Star Trek vessel. Celebrity astrophysicist Neil deGrasse Tyson has spoken highly of the influence and legacy of the original Enterprise on
