I have no idea. It might be only be some animated map of some kind I would guess. Triggered by very close proximity of a ships cockpit, and then direction the player is looking. Used sparingly it could work for all sorts of small or large windowed areas from space station, to ground bases at night.
Which is why I added maybe a future post-release update.
Same as tracks to and from land bases with vehicles moving along the paths going about there duties etc. Bases and small outpost/mines set into and over hanging valley and cliff faces, with elevators being used.
Large space stations could also have exterior elevators being used. Exterior elevators like we see in the Sean Connery 1981 film 'Outland'. As miners descend down a valley cliff face on a moon. [Youtube clip link] (3:20m onwards)
