Astronauts, people who fly into space, need special
training. First they go to Houston, Texas. That is the home of the Johnson
Space Centre. There they are tested to see how strong and smart they are.
One of the fi
rst
tests is for the heart. The people walk or run, then the space doctors see how
fast their hearts are beating.
Another important test is performed. In this test the
person must curl(蜷曲)his body up in a ball. When he is in that
position, he is put into a round cloth bag. The doctors give him no idea how
long he will have to stay in the bag. If a spaceship broke down in space, the
astronauts would get into bags like this. Then they would have to wait and curl
up in darkness, until help could arrive. You can see that an astronaut must not
be afraid of tight space or darkness.
After the tests, only the best people are chosen to
start astronaut training in a training centre. The astronauts in training learn
many other things. They learn how to jump out of a moving airplane. They learn
to how to blow up a lifeboat and get into it while they are in the ocean. The
astronauts also have to learn how to get lifted out of the ocean by helicopter(直升机). That may look fun, but it can be dangerous.
After they finish training, the astronauts continue to
work. They stay in good shape by running and doing exercise. They read about
their special jobs. In that way they can learn new facts about space travel.
Then the big day comes. The astronaut is told to go to
work on a flight into space. The crew members(全体船员)get
to know each other first. Then they can learn which job each will do.
