Tranquillity Base was the name given by Astronaut Neil Armstrong to the landing site on the moon where the Apollo 11 Lunar Module Eagle landed. The lunar coordinates of Tranquillity Base are 0 degrees 41 minutes 15 seconds North, 23 degrees 26 minutes 0 seconds East, which is located in the south-western corner of the lunar plain called the Sea of Tranquillity (Mare Tranquillitatis) near the craters Sabine and Ritter, and a rille unofficially called 'U.S. Highway Number 1'.

IAU

Unlike most monikers bestowed on lunar landmarks by Apollo astronauts, the International Astronomical Union officially recognizes the designation 'Tranquillity Base'. It is listed on lunar maps as Statio Tranquillitatis, in order to fit with the Latin names that are ubiquitous on lunar maps.

NEEP602 The Real World and Lunar Base Activation Scenarios (4461 words)
Both technical and managerial issues must be addressed when considering the establishment of a lunar base that can serve the needs of human civilization in space Many of the technical issues become evident in the consideration of hypothetical scenarios for the activation of a network of lunar bases.
The lunar landing frequency required to support the activation of a third base has not been examined, but it is likely that either a higher landing frequency or another major increase in payload weight landed per landing will be required unless it becomes possible to bootstrap additional bases from the first two.
The first landing at a base site (Day -28) is an automated or remotely guided placement of an HM keyed to a precisely determined and nonhazardous point on the surface and to the plan for the final architecture of the base.
