But one thing man knew before he ever reached the moon was that there was no life on it.There is no atmosphere on the moon. The lack of air means that the moon is not protected from any of the sun’s rays. The sun sends out heat and light radiation (辐射). Life on the earth depends on heat and light. But the sun also sends out dangerous kinds of radiation. The earth’s atmosphere protects us from most of them. On the moon, however, there is no atmosphere to stop the radiation.

This is hotter than boiling water. The hot lunar day lasts two weeks. It is followed by a night that is also two weeks long. At night the temperature drops to about 260 degrees below zero Fahrenheit.
