Luna

See The Moon on Wikipedia.

The Earth's only natural satellite, Luna, is often just referred to as 'The Moon' by the majority of Earth's populace. It is governed by the Colonial Administration of Luna (CAL) and has a population of approximately 1.7 million.

Characteristics
The lunar surface consists mostly of large spaceports for processing and shipping cargo to and from other colonies, as well as massive solar energy farms and long-range communications arrays. Underground subway tunnels have been created for travelling between surface structures, with the majority of the populace living in connected habitats underneath the ground, providing some natural protection against radiation and temperature variations on the lunar surface. Artificial gravity generators have been utilized in several of Luna's larger cities in order to compensate for the lack of gravity present.

While Luna's population may be relatively small in comparison to other colonies, it has a strong economy and a large workforce, as the colony presents many job opportunities for blue-collar workers seeking employment.

History
Humanity, incentivized by a rivalry between two historical superpowers, first reached Luna in the year 1969 with the Apollo-11 rocket. Astronauts Neil Armstrong and Buzz Aldrin were the first two men to step foot on the moon. Public interest in space-travel, however, waned over the following years, with the famous 'space race' of the 20th century coming to its conclusion. Following the Apollo-17 mission in 1972, humanity would not revisit the moon for some time.

With the Earth's growing population crisis, starting in the 2040s, the United Nations sought to expand out amongst the stars with their own space program. Luna's close proximity to the Earth made it a prime location for early colonization efforts, and with the launch of the 'Hope' series rockets in 2054, the UN's lunar colonization mission was largely considered a success.
