The earth is large, and for several thousands of people filled her huge and amazing things: the pyramids, the giant walls, cities, and many others. But for the International space station (ISS), which orbits the Earth at an altitude of 400 km, our planet might seem rather small place. Houses, roads and buildings just disappear.
