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 kilometres away from the Earth.A plane can not fly to the moon,because the air reaches only 240 kilometres away from the Earth.But something can fly even when there is no air.That is the rocket.

How does a rocket fly?There is gas (气体) 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 out into the space.Rockets with men in them have been to the moon.Several satellites without men in them have flown to another planet much farther away than the moon.One day rockets may be able to go to any place in space.

In the universe,as we know,there is the Sun,the moon,the Earth and a good many stars.Through our geography lessons,we know the Earth goes round the Sun,and the moon goes round the Earth.We have day and night because the Earth keeps turning all the time.When our part of the Earth turns to the Sun,it is day.When our part of the Earth turns away from the Sun,it is night.

Just because the moon is closer to the Earth than the Sun,it looks much bigger than the Sun.Big things will look smaller when they are farther,and small things also look bigger when they are nearer.

The Sun is bright enough to give out very strong light.The moon can't give any light at all,but it looks quite bright,too.Why?In fact,the light from the moon comes from the Sun.The moon looks much bigger and brighter than the stars.But actually (事实上) the stars are much bigger and brighter than the moon.They look smaller than the moon also because they are farther away from the Earth.

There are still many other planets in the universe.But of all these planets,only on Earth there are living things and people can only live on Earth,too.But at 9∶00 am on October 15th 2003,Chinese astronaut Yang Liwei was set up to space.He stayed there for 21 hours.It was the first time for Chinese to get into space.
