A trip to Mars and back is a dream for many space travelers. Rockets launch into space from spaceports like Baikonur. How do astronauts move in zero gravity, what is the purpose of the spacesuit, and what is there to eat in space? The Moon - 12 Apollo astronauts have walked on the Moon so far. Researchers have since discovered how the Moon was formed, where its countless craters come from, and why a meter-thick layer of dust covers its surface. Life on Earth would look very different without the Moon. Author: Dr. Manfred Baur Narrators: Crock Krumbiegel, Anna Carlsson, Jakob Riedl. Duration: approximately 70 minutes.
