Planetarium
MOVIE: Satelix
Satellites are with us all day. When we wake up, go to school, to work or for a trip, and when we spend time with our families in the evening, too. And at night? In the darkness of the night, they guard us while we sleep. Without them, we would not have navigation in our cars or mobile phones, accurate weather forecasts, and in fact many everyday items, either.
