"Celebrating New Year's Day 16 Times: The Unique Experience of ISS Astronauts"

Astronauts aboard the International Space Station (ISS) will celebrate the New Year 16 times due to the station's orbit, which results in 16 sunrises and sunsets within 24 hours. Traveling at a speed of about 28,000 kilometers per hour, the ISS completes an orbit around Earth every 90 minutes, allowing the crew to experience 45 minutes of daylight followed by 45 minutes of darkness repeatedly. This unique condition enables them to conduct various experiments and provides stunning views of Earth, although it challenges their circadian rhythms.
