How to spot the International Space Station from Earth

Every ninety minutes, a structure the size of a football field traces a luminous arc across the sky, carrying human beings in orbit above the very people who might pause to watch it pass. The International Space Station has circled Earth without interruption for more than two decades, yet most who live beneath its path have never thought to look up at the right moment. In an age of abstraction and mediated experience, this remains one of the few opportunities to witness, with unaided eyes, something humanity actually built and placed among the stars.
