In this episode Ulisse takes viewers on an unusual journey around the earth. This exceptional journey starts from the sky and shows our planet from a unique perspective. We get on board the means of transport that is currently traveling faster than anyone else: think almost 28 thousand kilometers per hour: it is the International Space Station which takes only ninety minutes to orbit the earth. Every six months, a new crew leaves the earth for this sort of orbiting home; a scientific laboratory floating 350 kilometers above the Earth's surface. Let's see how the daily life of astronauts forced to live together in confined spaces for months unfolds. Alberto Angela shows us what the earth looks like seen from space: it looks like an uninhabited planet, without man. With the naked eye you can see the sea, you can see the land... But you cannot perceive the cities, the buildings, the buildings.
