Scientists have always wanted to know more about the universe. Years ago they knew many things about the moon. They knew how big it was and how far away it was from the earth. But they wanted to know more about it. They thought the best way was to send men to the moon.
The moon is about 384,000 kilometers away from the earth. But something can fly even when there is no air. That is a rocket(火箭).
How does a rocket fly? There is gas in the rocket. When the gas is made very hot inside the rocket , it will rush out of the end of the rocket, so it can make the rocket fly up into the sky.
Rockets can fly far out into space. Rockets with men in them have been to the moon. Several rockets without men in them have flown to another planet much farther away than to the moon. One day rockets may be able to go to any place in space. ( ) 1.Scientists have known the moon is.

If you dream of becoming a spaceman after you grow up, get started now! A spaceman needs a strong body and mind. See here what Shenzhou VI spacemen are able to do. Don’t you still have a long way to go?
Shenzhou VI spacemen are able to live upside down(头朝下).
They did this not just during sleep, but also when eating and going to the toilet. Before they flew into space, they had had lots of practice. Each upside-down training time lasted for 20 days.
In Shenzhou VI, Chinese spacemen aren’t just spaceship drivers but also machine repairers and scientists.
They have to know every part of the spaceship and how it works. If something goes wrong, they must know how to repair it. Also they do scientific experiments in space.
Shenzhou VI spacemen know how to live in the wild. They took a knife, a gun and some dye(染
7
料) with them into space. If they land in forests, the knife and gun can protect them from wild animals. If they fall into the sea, the dye can color the water around them yellow. This can help people find them easily on the sea.
Shenzhou VI spacemen can’t get dizzy（眩晕的）. A spaceship is not a plane. When it goes up, the extra gravity force(重力) can break people’s bones. Spacemen must have strong bodies for this. They can’t get a headache or be sick. With many things to take care of, they’ve got no time for sickness.
