Moon Exploration Many people wonder why some men want to live on the moon. 1 It is a silent place, where the weather is hot and sunny or cold and dark. Its suce is dull and almost colorless. There are no lakes, rivers, or plants to provide beauty. 2 Astronauts on the moon certainly miss the comfort of life on the earth. But man has always moved to new frontiers. Every pioneer in a new land has faced er and hardship.
Some scientists hope that continued work will be done on the moon. Many experiments will be done there more easily. 3 Matter can be heated to very high temperatures without chemical change when it is in a vacuum. Air, dust and clouds cannot block human being’s view of space from the mood. The very high or very low temperatures and low gravity on the moon will be used for many experiments. One very important use of the moon will be to launch spacecraft.
Man might be able to learn much about his own body by living on the moon. 4 Man would be in control of the community of life in which he lives. Bacteria could be removed from the air in this community.
Gravity is one thing that would not be under human being’s control. Some scientists believe the low gravity of the moon would be healthful for man. The heart would not have to work so hard. The body would need less energy to move than it does on the earth. 5 Much exercise would probably be needed to keep the body in good condition.
A.He would be living in a habitat that he made for himself.
B.However, the human body might change during long stays on the moon.
C.But man cannot live there happily and comfortably.
D.It is probably not the kind of place where most men would choose to live.
E.A walk on the moon’s suce is filled with er.
F.Some large experiments are very easy to do in a vacuum. Moon Exploration
