Manga is just doing a bad job of conveying scale. The space stations are megastructures, the hanger is way larger than that panel implied.
On that note, I'm also disappointed the manga is using the generic 20th century mansion interiors for the noble ship. I was expecting something more modern sci-fi luxury like that spaceship from the Passengers movie.
