That doesn't care about the surface normal, which is used for lighting calculations, it cares about the winding order.
I totally agree that it (at least part of the problem) does look like a back-face culling issue.

However, regarding normals vs. winding order, my understanding is that Blender always keeps winding order consistent with the face normal. I don't think there's any mechanism to visualise or directly change the winding order of faces within Blender anyway, you can only display (and flip) the face normals, which makes sense since the face normal is much more intuitively meaningful. If I had to guess, I'd say it probably doesn't store face normals separately anyway, but just computes them on demand, and the control to flip the normal is probably implemented just by flipping the winding order.

I have not tried to test these things though. It should be easy to create a test model to check in the model viewer that back-face culling is doing what you expect, and then flip the normals in Blender, re-export, and check again.

For directing people to their pad, perhaps a sort of guidance-rectangle system would work. Like, concentric rectangles around the pad, each a little higher than the one inside it.

Here's what they're doing for Elite: Dangerous. I'm thinking something similar (and simpler) would suffice:

Hmm. I just found some interesting stuff regarding atmosphere retention:
Plasma window.
It seems that it can keep gases in up to 9 atmos.
It's quite small scaled, but some maglev tube launch systems mentioned it for keeping the tube at vacuum, so it might be a believable idea to use something like this for the station portals.

The shear fact that this technology actually exists, right now, and is probably being used somewhere while I sit here with my cup of tea made my jaw drop!
Roll on fusion...
