SpacecraftPeople had thought of building spacecraft several hundred years ago. They had thought of going

to the moon and many other planets. Papers on spacecraft can be found among the papers of famous

scientist who lived centuries ago. However, the craft could not be built until after World War II.

It is not easily to build a spacecraft. A spacecraft needs a good rocket that is strong enough to

send it outer space. Such a motor was not developed until 1944.

A spacecraft also needs as many as rend million very sophisticated parts. These parts are needed

so that the craft can function well when it is flying far away from earth. These parts must have very

high precision elements. Each of them must have the right shape and the right size. Such parts could

not be mode until after 1940.

Today, spacecraft are being made all the time. They have to be enough to carry astronauts into

outer space. What does a spacecraft look like? A spacecraft usually consist of three rockets that are

joined together. The three rocket are called stages. The first stage takes the spacecraft to certain speed

and falls away. The second stage takes it to speed twice as great as the first, and then it also falls away.

The third stage takes the spacecraft to its top speed of more than 38,600 kilometers per hour.

Where is the place for the astronauts? It is at the top of the spacecraft. In the nose of the third

stage a capsule. In this capsule are the astronauts and the instrument package. This capsule is actually the smallest part of the ship. But all sorts of very sophisticated instruments are found into his capsule.

This little capsule is the most important part of the ship.
