A controlled deorbit requires the use of several core systems, including those for communications, power, and avionics. Some of the ISS machinery was not specifically certified to perform in a depressurized environment. (NASA believes that critical systems would remain operable, based on technical analyses, and emphasizes that many of these systems are already used in vacuum.) Another thing to worry about: the ISS losing control over its orientation in space. The spacecraft could start tumbling, flipping the station’s solar arrays away from the sun, taking the primary source of power with it.
