Why Antarctica Is Being Explored(为什么要勘探南极洲)

14. As to space research, there is no place on earth better suited than the South Pole for certain kinds of observation. Here is a firmly fixed point, in contrast to the drifting floes that cover the North Pole; from it all directions are north, and during the six months of darkness the stars circle around a point directly overhead. The United States established an observatory there in 1957 for the I.G.Y. and has maintained it ever since.

14、在空间研究方面,南极是地球上最适宜的进行观察的地方。与北极上;覆盖的漂流浮冰相比,这里是一个稳定的点。这里所有的方向都是北,在长达六个月的黑夜中,星星围绕的中心点就在头顶。1957年,美国为国际地球物理学年会在此处建立了一个观测站,并且一直维持至今。

15. Now it is an ideal space tracking station. Any vehicle on a mission in the southern half of the heavens remains continuously "visible" to an antenna at the pole. Such a station is also able to play a unique role in interrogating earth satellites in orbit over both poles.

15、现在,这里是最理想的空间跟踪站。在南半球的太空中执行任务的所有飞行器都可被极点上的天线持续追踪。同时,这个观测站还在监视两极轨道上的地球卫星方面发挥不可替代的作用。

16. Such satellites—maintaining their steady sweeps as the earth revolves beneath them—cover all parts of the globe and hence are ideal for weather observation, communications and other tasks. The South Pole would be the check point on each circuit, snatching the data from space, processing them in computers within seconds and relaying them to the rest of the world.

16、这些卫星处在平稳旋转的地球上空,几乎可以对全球的所有地区进行稳定的扫描,因此能很好地完成气象观察、通讯以及其它任务。南极点将成为这些卫星环球轨迹的检查站,从太空采集数据、通过电脑在几秒钟之内处理数据,并传送到世界各地。

17. On all these counts, the scientists justify their voyages to Antarctica and the vast sums needed. But essentially their argument is a simple one. The great continent to the south is still largely unknown. In the quest for fundamental knowledge, which is the heart and soul so all science, it cannot be ignored.

17、综上所述,科学家们认为应当进行南极勘探,同时需要大量的资金。但是,他们最根本的论据很简单:南方的这块大陆在很大程度上仍是个迷。为了探索基础知识—而探索基础知识也正是科学的核心和灵魂所在—这个地区不容忽视。
