(Note: If you want to understand what's going on here, I recommend you at least glance over my A to Z Plan for this iteration of the Challenge.)
The Drake Lunar Base was completed on November 9, 2044 in the Lacus Gaudii area of the Moon. The project was financed by NASA in association with several other space programs across Earth. Twenty men and sixteen women landed at the Base on April 15, 2045. They came from the United States, Israel, the United Kingdom, the Republic of Ireland, Australia, Russia, and the Central American Confederation.
The Base was one hundred meters long, ten meters wide, and three meters tall. It contained twenty-seven rooms including two men’s restrooms, two women’s restrooms, a planetary science room, a life sciences laboratory, an auxiliary occupational room, a kitchen, a game room, and eighteen bedrooms.
There was artificial gravity set to 0.97g and idealized artificial atmosphere within the Base.
The only entryway/exit to/from the Base was a single airlock.
