Space Research
Does walking on the moon make life better for people on earth?【51】all the problems of our own world, why should we be spending huge【52】on trips to outer space? Such questions as these are often asked, especially【53】those whose tax money is paying for space explorations. The answers to these questions are many and【54】.
Up to now, the practical benefits resulting【55】space research have included the development of new methods and skills, new processes, new services, new products, and even new companies created to make use of what【56】through space travel. Also among the benefits【57】better education (especially in scientific subjects),【58】management, higher quality of industrial products ,and rapid【59】growth.

In addition to improving the quality of existing products, the space program has been responsible for the development and improvement of new ones. The most important is the computer. To bring the endangered Apollo 13 astronauts home safely in 1970,a new flight plan had to be made taking account of an unbelievably complex combination of elements. The computer accomplished this task in seventy-two minutes, whereas a man or a woman working with pencil and paper take more than a million years! If there had been no space program, it is doubtful that computers would now be so widely used in industry and government.
