SkylabAfter intense solar activity results in a brief swelling of Earth’s atmosphere, Skylab‘s days are numbered: it has already been slowed enough by contact with the outermost layers of the atmosphere to come tumbling back to Earth. Unoccupied since 1974, the now-derelict space station is expected to disintegrate harmlessly over the Indian Ocean, but NASA is caught off-guard when unexpectedly large chunks of Skylab survive long enough to crash into the Australian outback. No one on the ground is hurt, and NASA is jokingly fined for littering.
