The Betty Hill star map trail
a) Drax space station illustration for Moonraker by Ken Adams (film released 1979)
b) A star map (Summer 1964) drawn by Betty Hill, with the lines representing trade routes between stars and the broken lines representing exploration routes.
c) The map drawing would be reversed to make it tie in with Ken Adam's design
d) Trade routes to other stars leading from the possible Zeta I Reticuli.
The arm to the left of the sphere supposedly leads to Alpha Mensa . and while the upper space station module with an end view of the solar panels sticking out of the side seems to be based upon that.
The upwards trade routes to stars above become the main upwards antenna. .
e) The horizontal trade routes become the horizontal corridor tube leading to modules either side of the station
