10.1 We are often told that technological know-how, acquired in exploring space, will be utilized to make life better on earth. Is this really the case? What has the space exploration done to relieve the suffering of the earth's starving millions? In what way has it raised the standard of living of anyone of us? Man may put human beings on the moon, but there is growing skepticism about his ability to solve human problems closer to home.

我们经常听说在探索空间中获得的技术知识将用来改善我们地球上的人的生活。情况真的如此吗？太空探索对减轻地球上正在挨饿的千百万人的痛苦到底做了什么呢？它从什么方面提高了我们的生活水平呢？人类能够把人自己送上月球，但人们越来越怀疑其解决地球上人自己问题的能力。
