ISS Crew Experiences 16 Sunrises Daily, But Ignores Them All

Four hundred kilometres above the Earth, the sun rises sixteen times a day — yet the crew of the International Space Station watches none of them. Orbital mechanics dictate the rhythm of the cosmos outside the windows, but inside, human beings have quietly engineered their own time, anchored to a fixed clock and artificial light rather than the ancient signal of a turning planet. It is a small but profound act: the deliberate uncoupling of human life from the celestial cycle that shaped it over millions of years, undertaken not in defiance of nature, but in careful negotiation with it.
