Should countries undertake space exploration?
选项
答案
In the past, there were just two nations which undertook serious space exploration, namely the United States and the former Soviet Union. In fact, the "space race" began in the late 1950s, with the Soviet Union launching the first manned rocket. It became a matter of national pride, as each country attempted to outdo the other in enhancing its international standing. When Americans landed the first man on the moon, it clearly represented a monumental national achievement.
Furthermore, space research has produced a variety of practical and beneficial discoveries and applications. For instance, Teflon, a non-stick surface used in cooking utensils, such as frying pans, was developed as a result of the space programme. Moreover, we have a better understanding of climate patterns, together with a modern system of electronic communications, as a direct result of the hundreds of satellites which encircle our planet.
On the other hand, space research has considerable disadvantages. Obviously, space research is often carried out for military purposes. It undoubtedly adds to the arms race, endangering world peace. Think, for example, of American "Star Wars" project. How on earth does this benefit mankind?
Environmentally, there are significant reasons against launching rockets into space. The huge boosters used by vehicles escaping the earth’s gravity produce considerable pollution, damaging the precious ozone layer. In addition, there are countless pieces of "space junk" floating around above our planet which one day could constitute a serious hazard.
