Passage Four
A very strange old man used to live in our town. He didn’t do anything as the rest of people did. He lived alone and didn’t talk to anybody. He liked to walk in the woods where there were no roads, following the narrow paths made by animals. People were afraid of him. They thought he was crazy and might do something terrible, like hurting one of the children.
One day a little boy disappeared. His parents looked for him for hours, and finally the whole town started a search of the woods. Some people thought the strange old man bad taken the child away.
Several hours later, the boy was found, very cold and hungry, and it was the old man, who knew the woods so well, who had found him. After that, he still lived alone and walked in the woods, but no one was afraid of him any more.
Until the very latest moment of his existence, man has been bound to the planet on which he originated and developed. Now he had the capability to leave that planet and move out into the universe S1.() to those worlds which he has known previously only directly. Men S2.()have explored parts of the moon, put spaceships in orbit around another planet and possibly within the decade will land into another planet S3.() and explore it. Can we be too bold as to suggest that we may be S4.() able to colonize other planet within the not-too-distant future S5.() Some have advocated such a procedure as a solution to the population problem: ship the excess people off to the moon. But we must keep in head the billions of dollars we might spend in carrying out the project. S6.() To maintain the earth’s population at its present level, we would have to blast off into space 7,500 people every hour of every day of the year.
Why are we spending so little money on space exploration S7.
