According to Fox News, astronauts aboard the International Space Station (ISS) see roughly 16 sunrises and 16 sunsets every 24-hour day, a result of the station's rapid orbit around Earth.
The ISS travels at about 17,500 miles per hour, completing one full orbit every 90 minutes. This means the crew experiences a sunrise or sunset approximately every 45 minutes as the station moves from daylight to darkness and back.
While this frequent cycle can affect astronauts' circadian rhythms, they adjust by following a strict schedule based on Coordinated Universal Time (UTC) to maintain regular sleep and work patterns.
