International Space Station Explained — How a Falling Laboratory Stays Alive

What really happens on the International Space Station? The station is falling around Earth right now — gravity is still strong up there. Then how do people live and work inside a falling laboratory? Follow the connected systems one at a time: the external truss and pressurized modules, solar arrays and batteries through sunlight and eclipse, U.S.-segment air and water recovery, electrolysis, internal water and external ammonia cooling loops, radiators, control moment gyroscopes, drag and reboost, and how visiting spacecraft dock or are berthed with Canadarm2.

Interior systems, cutaways and equipment views are AI-assisted illustrations and simplified diagrams, labelled on screen; they are not exact ISS hardware. Narration is a synthetic ClueShift voice. Stable system principles only: no claim about the current crew, exact altitude, power level or visiting-vehicle schedule. U.S.-segment examples are identified as such.
