ISS Crew Experiences 16 Sunrises Daily in Orbital Rhythm

Sixteen times each day, the crew of the International Space Station watches the sun rise over the curve of the Earth — not as a poetic metaphor, but as a literal consequence of traveling at 17,500 miles per hour in low Earth orbit. Every ninety minutes, the station crosses the boundary between night and day, compressing what humanity has always known as a single daily cycle into something closer to a metronome. This peculiar condition invites a deeper question: how much of what we call human experience is simply an artifact of where, and how slowly, we happen to move through space.
