Halo: Reach reference

SF video games can't go wrong with some Star Wars themes hidden away. We cannot forget the hideously cheesy ion cannon in Starcraft 1's Terran finale ripped right out of Hoth's cold, frozen ground.

I present my theories on Reach's opening level, Winter Contingency. The architecture of the relay station circled below seems awfully familiar.

Its a bit more than coincidence huh? I also must mention the role reversal seen in the later half of the level. Kat is frantically trying to close the door to the station while Leia/R2D2/Han were trying to open the doors.
What other SF references lurk about the campaign?
