Along with a script and looking for voice-over actors, I've been looking at possible designs for the base in which the story will be set. I looked at various science fiction shows of the 1960s and 1970s for inspiration, taking ideas from various themes from this artistic period from productions such as 2001: A Space Odyssey, Captain Scarlet and the Mysterons, Space 1999 and Frank Herbert's Dune.
While inspired by moonbase designs of the 1970s, I am tempted to move away from the design of Moonbase Alpha. Although its design is quite ubiquitous which might make things tricky. There have been moon-base designs that feature a donut ring around a central core, much like the station in 2001: A Space Odyssey. Other moonbase ideas involve tunnels and prefabricated structures. Though a permanent construction makes the whole thing feel established as David mentioned he's been on the project for five years. I have considered that later in the story David will become less of a neat-freak, his workstation and dormitory will be progressively overcome with clutter.
