At the main axis area of the space elevator was the gravity-free section of Celestial City and the port of the city. Since the launch of the asteroid mining program, countless small and medium-sized transport vessels docked against the port, as they waited for the robotic arms to load and unload the ores inside the containers.

In addition to the transport vessels that carried ores, a passenger ship shaped like a cuboid occasionally flew out from the transfer station and headed for the Moon. Since Celestial Trade announced regular flights between Earth and the Moon, travel between Lunar City and Earth became much more frequent.
