The peripheral modules are individually connected to the central hub. They are all of an ellipsoidal design with a radius of one thousand meters along the x-axis and a radius of one hundred meters along the y-axis.
Each module has its own self contained life support system as well as individual propulsion systems since each one is designed to be detached and operated autonomously.
Post here if one desires to be in the modules but not any one specific location for long. Otherwise, create threads for specific locations in the respective hubs.
