      Some day you may go to the moon. A tall rocket will take you into space. The rocket flies a long

way to a space station. You will stop there for a short time. Then a big spaceship will take you to the

moon.

      About three days later,the ship slowly goes down and gets to the moon. You are now on the moon,

but you can not leave your spaceship. You must put on a space suit for the moon.It is very hot in the day

and very cold at night.If you don't wear a space suit,you can't live there. You jump out of the spaceship

and begin to walk.The moon is much smaller than the earth. The things on the moon are lighter than those

on the earth. You jump high in the air every time you take a step.

     The moon moves slowly, so one day on the moon is as long as two weeks on the earth and one night

is just as long as two weeks on the earth. It never rains on the moon, and everything on the moon is dry.

There are no trees or other living things of any kind. There is nothing to do there. The earth is a far better

 place to live on,but scientists are trying to make the best of the moon.
