Do you know the Blue Marble? This is our earth! The name comes from one of the most famous photos of the earth, namely the photo taken from Earth in 1972 by the crew of the spaceship Apollo 17 from a distance of 45.000km. In this Deep-Space-presentation, we fly into space without a spacecraft and observe what we can see on Earth. We also observe how the Earth changes at night and during the different seasons.
