Tranquility Base was a historical landmark with an associated Federation shipyard located in the Sea of Tranquility area of Luna.

History and specifics

On 20 July 1969, Tranquility Base was the landing site for NASA's Apollo 11 mission, where Humans first stepped foot on Earth's moon. Neil Armstrong and Buzz Aldrin explored the site, collecting rock samples and conducting experiments. (Last Unicorn RPG module: A Cadet's Guide to Sector 001 Earth, ST reference: Spaceflight Chronology, TOS novel: Prime Directive)

In 2019, all six NASA Apollo program landing sites were declared historic landmarks. (ST reference: Spaceflight Chronology)

22nd century

In the early 22nd century, the New Berlin colony was established about 30 kilometers north of Tranquility Base. (Last Unicorn RPG module: A Cadet's Guide to Sector 001 Earth)

A shipyard was associated with the site. Among the many Starfleet vessels to be constructed at the yards were the Constitution-class starships USS Defiant and USS Excalibur. (ST reference: Star Charts, ENT episode: "In a Mirror, Darkly", ST reference: Ships of the Line)

23rd century

In the 2230s or 2240s, James T. Kirk visited Tranquility Base as a boy, his first trip off-world. (TOS novel: The Ashes of Eden)

By the 2260s, the historical site had become Tranquility Park, a resort and park, a popular attraction among students and newly married couples. A transparent aluminum wall separated the artifacts and a viewing area at the park, with the lunar module still exposed to the vacuum of space. Leonard McCoy visited the resort in 2269 and chatted with Glynis, a nine-year-old girl who was able to recite facts about the mission. (TOS novel: Prime Directive)

On 20 July 2269, 300th anniversary celebrations of the Apollo 11 mission included plans for the Enterprise space shuttle to join a parade flyover of the landing site. (TOS novel: A Flag Full of Stars)

24th century

By the 24th century, an amusement park was located at Tranquility Base. In 2374, Jake Sisko and Nog owned a holosuite program that simulated the park. (DS9 - Millennium novel: The Fall of Terok Nor)

By this time, the landing site had been incorporated into the UFP Aerospace Museum-Smithsonian Annex. (ST reference: The Worlds of the Federation)

Jean-Luc Picard experienced three days in a holodeck simulation of the Apollo flight and landing at Tranquility Base. (TOS novel: Captain's Blood)

On 20 July 2369, 400th anniversary celebrations of the Apollo 11 mission culminated in the landing of an Apollo replica one mile from Tranquility Base. More than 100,000 spectators watched the event from a nearby pressurized stadium. (Star Trek Magazine Issue 162: "Star Trek Spaceflight Chronology")
