A journey to Mars or Saturn would be a dream come true for many astronauts. From launch pads, such as those at Baikonur, rockets lift off into space. How do astronauts move in zero gravity? Why do they wear spacesuits and what do they eat when in the spaceship?
Up to now, only twelve Apollo- astronauts have stepped on to the moon. Since then, scientists have discovered how the moon was formed, why it has endless craters and why a thick layer of dust covers its surface.
