Science & TechFact

Astronauts on the ISS see 16 sunrises a day.

The International Space Station orbits about 400 kilometres up at roughly 27,600 km/h. One lap takes a little over 90 minutes, so around 16 orbits in 24 hours, each with a sunrise and a sunset. Gravity up there is still about 90 % of Earth's; the crew floats because the station is constantly falling around the planet.

Useful: The ISS is visible to the naked eye as a bright, fast-moving dot; NASA's Spot the Station lists pass times.
