Astronauts on the International Space Station (ISS) experience roughly 16 sunrises and 16 sunsets each day, Fox News reported, highlighting a fascinating aspect of life in low Earth orbit.
This phenomenon occurs because the ISS orbits Earth at about 17,500 miles per hour, completing a full orbit every 90 minutes. As a result, the station passes from daylight to darkness and back again 16 times in a 24-hour period.
The rapid cycle of day and night can affect astronauts' circadian rhythms, requiring careful scheduling of sleep and work periods to maintain health and performance during long-duration missions.
