A Space Station Hub is a 4-way, dockable connector for space station construction. Up to 4 space station modules may be docked together in this one location.
A small observation window is visible in the center of the hub. Slightly to one side of the window is a small white dot, indicating the initial docking side available when the hub is first docked.
This module allows the transfer of Power, Fuel and Oxygen. It uses 5 Power units when activate. Even when turned off its ability to transfer consumables is not impaired.
