No, this isn't a claim about time travel. The way astronauts on the International Space Station experience daylight is due to orbits and rotations. The ISS moves at an incredible speed around the Earth—it takes just 92 minutes for the station to make one complete orbit our planet. Because of the Earth's rotation, astronauts aboard the International Space Station observe days and nights differently than we do on Earth. They will see 15 to 16 sunrises and sunsets in any given 24-hour period.
