Guanghan Port (广寒港) — major lunar launch and landing facility, one of two primary orbital ports on Luna (alongside Kosmodrom Zarya). Named for the Guanghan Palace of Chinese lunar mythology. By 2157, together with Kosmodrom Zarya, handled more than a hundred launches per day, with each transit cutting through accumulated orbital debris bands dating to the first commercial launch booms of the 2030s. Guanghan’s resident population — ~320,000 as of 2155, ~350,000 as of the 2165 Colonial Census — makes it the largest single settlement on Luna.
