its official name is Armstrong base, most people just say
“Moonbase”. Its crater is shown above a few years after the
story in Moonfall takes place. Looking south, the structure in
foreground is the roof replacement over the garage. Two suited
astronauts stand atop the newly installed blast door. We can
barely see a new access ramp below which extends over the scar
and crater from the iceball impact. The new Operations tower is
shown roughly crater center. A bus can be seen moving towards
the Powerplant (green). Beyond the powerplant the big
fabrication buildings are where larger structures are
assembled. Some lattice towers and carts can be seen on the
ground beyond the big fab buildings.
the big fab structures the podrail system dominates the
southern end of the crater. The two ramps, landing and
launching are each a kilometer long and are angled upward at 20
degrees. The passenger terminal is underground, below the pod
docking facilities in between the ramps. A racetrack podrail
surrounds the pod docks and just beyond that is the Pod
maintenance and storage facility. On its right is the switch
track where pods are reversed so they can launch with
passengers facing forward. (It helps to have the thruster
pointing backward too.) A pod proceeding to launch is seen just
before mounting the West ramp for launch.
underground pressurized tuberail system connects the
underground pax terminal to the Ops workspace, then continues
underground into the habitat, where reception has been moved
down a level from its previous position adjacent to the garage.
left and more open western edge of the crater lie four blast
pits for non-rail landings and launchings. Each pit is roughly
one kilometer in diameter and is surrounded by a blast fence to
deflect dust kicked up in landings/launchings. Between each
pair of pods is a loading/unloading crane which can also serve
as a gantry if required. On pad A, the northernmost, sit three
light mining craft, and on pad C is a heavier duty freighter.
sprays of color on the usually monochrome lunar surface have
some functionality. Red indicates an airlock, Green is required
for DEVAS fixed powerplants. The mixed yellows are remnants of
an early attempt to define roadways with a colored dust, most
of which was redistributed or covered in the iceball incident.
The blast pits are relatively free of dust and have been
impregnated with a sprayable coloring agent to make them more
visible in the event a manual landing is required.
way to spray a binding agent across a cold airless gap also led
to mooncrete, the product used to reconstitute excavated
aggregate into construction blocks at the Block Plant. That
facility is out of view to the right, roughly a kilometer away
from the conveyor vent at the top of the central habitat
dropshaft. Out of view to the left is the recently installed
reservoir cap, where ice is deposited.
