The first part to take place on the moon has been written in Lunar Penal Colony. I found out about these things on the moon called mascons that tended to occur in lunar basins. I couldn't find a lot of information related to exactly how they worked on the moon, except they were gravitational anomolies that had caused satellites to crash and made lunar navigation difficult. It seemed like gravity in these areas were denser than other areas. So, it seemed only natural to choose one of these basins to put the penal colony on.
Orientale Basin is a real basin on the moon, and naturally the name extended to to the station as well. As I think about it, the name Orientale Station is a much better name than Lunar Penal Colony. Perhaps that could become the name in the future, or something similar. I'll have to see how the story continues to progress, to see if a better name comes up in the future. For now, the ugly name Lunar Penal Colony will remain.
