Such questions as these are often a

2、sked, especially by those whose ta money is paying for space eploration.The answers to these questions are many and varied.Up tonow, the practal benefits resulting from space research have included the development of new methods and skills, new processes, new serves, new products, and even new panie

3、s created to make use of what has been learned through space travel.Also among the benefits are better education (especially in scientif subjects), more effient management, higher quality of industrial products, and rapid econom growth.People all over the world are now served by improved weather pre

4、dtions, better munation systems, and better understanding of the earth and its environment.Everyone will benefit as observations from space make it possible to measure the earth"s resources and to observe whether or not they are being used properly.Increasingly, the space program will help our

5、world deal with the problems of the environment.It has already brought a new reciation of the ple system of whh man is only a part.One of the first areas of daily life to feel the effects of space travel was education.Amerans felt challenged by the news of Sputnik I in1957.Immediately their governme

6、nt responded by providing greatly increased financial support for U.S.education.Emphasis was placed on teaching more science and leaching it better, from the elementary grades through post-graduate school.Because education emphasized science and enneering, thousands of scientists and enneers were pr

7、oduced.These specialists partipated more widely in government and industry than ever before. In discussing how space travel has contributed to life on earth, some writers also emphasize the management methods whh were developed in the effort to land men on the moon.That ple operation required new me

9、Fortune magazine: " This is potentially the most powerful tool in man"s historyThe question now is whether such techniques can be refashioned and turned to other tasks as well."Another result of the space travel has concerned the quality of industrial products.Early in the Space Age,

10、some of the equipment used by astronauts failed to perform properly.Space program managers were convinced by these events that space travel would require greater assurance of quality and dependability than had previously been demanded in industry. To deal with the problem of quality and dependabilit

11、y, those in charge of the space program emphasized the need for testing industrial products.Many panies that had to develop tests for the space program also manufactured products for use on earth, such as cars and planes.Since some parts are used both in space systems and in products for ordinary li

12、fe, the emphasis on quality had spread through Ameranindustry.Many products are now more reliable than they might have been if men had not been sent to the moon.In addition to improving thequality of eisting products, the space program has been responsible for the development and improvement of new

13、ones.The most important is the puter.To bring the endangered Apollo 13 home safely in 1970, a new flight plan had to be made taking account of an unbelievably ple bination of elements.The puter acplished this task in seventy-two minutes, whereas a man or a woman working with pencil and paper would have taken more than a million years! If there had been no space program, it is doubtful that pu
