Robert A Heinlein was influential on a whole generation. His “The Moon is a Harsh Mistress” is generally considered one of his best works. This piece is my interpretation of the main locations in the novel. The Mass Driver is highlighted by a series of brass loops, while six other key locations are indicated by LEDs. An Arduino micro-controller flashes the mass driver to indicate a launch sequence, and the location names are Morse-encoded.
The Mare Crisium area is modelled to scale in all dimensions. The only aspect that is not to scale is the Mass Driver. Luna’s short horizon is obvious, as the perimeter dorsa are at or below the centre of the mare. Colouring of the mare features is subject to artistic license. The specific locations highlighted are a best guess based on multiple readings of the source materials.
