International Space Station

This video shows the view of the Earth from the International Space Station (ISS).

The ISS orbits at about 400 km above the Earth’s surface, making it a gigantic LEO satellite. Falling at 7.66 km/s, it views the sunrise/sunset every 90 minutes or so.

The ISS orbits at an inclination of 51.6°. This means the ISS does not pass over regions which lie above 51.6° N and 51.6 S° latittudes.

Because the earth rotates “underneath” the ISS, the ISS advances in longitude after each orbit. This allows the ISS to pass over different regions of the earth during each orbit.
