Modular artificial-gravity orbital refinery spacecraft

An orbital refinery spacecraft comprising:

• a hub section defining a longitudinal axis;
• an excavator segment coupled to the hub section, the excavator segment configured to prepare and convey raw material into the hub section;
• a first rotary ring segment configured to rotate about the hub section in a first direction, the first rotary ring segment comprising:
• a first refining module;
• a second refining module;
• and
• a third refining module;
• wherein a first angular position between the first refining module and the second refining module relative to the longitudinal axis is adjustable and a second angular position between the first refining module and the third refining module relative to the longitudinal axis is adjustable;
• a second rotary ring segment configured to rotate about the hub section in a second direction opposite the first direction, the second rotary ring segment comprising:
• a fourth refining module;
• a fifth refining module;
• and
• a sixth refining module;
• wherein a third angular position between the fourth refining module and the fifth refining module relative to the longitudinal axis is adjustable and a fourth angular position between the fourth refining module and the sixth refining module relative to the longitudinal axis is adjustable;
• and
• a third rotary ring segment configured to rotate about the hub section in either direction, the third rotary ring segment comprising:
• a first storage module;
• a second storage module;
• and
• a third storage module, each of the storage modules for raw or refined materials;
• wherein a fifth angular position between the first storage module and the second storage module relative to the longitudinal axis is adjustable and a sixth angular position between the first storage module and the third storage module relative to the longitudinal axis is adjustable.
