Trouble with the Hubble
原文
What is the special importance of a telescope in space?
The Hubble telescope was launched into
space by NASA on April 20, 1990 at a cost of over a billion dollars.
Right from the start there was trouble with the Hubble.
The pictures it sent us were very disappointing because its main mirror was faulty!
NASA is now going to put the telescope right,
so it will soon be sending up four astronauts to repair it.
The shuttle Endeavour will be taking the astronauts to the Hubble.
A robot-arm from the Endeavour will grab the telescope and hold it while the astronauts make the necessary repairs.
Of course, the Hubble is above the earth's atmosphere,
so it will soon be sending us the clearest pictures of the stars and distant galaxies that we have ever seen.
The Hubble will tell us a great deal about the age and size of the universe.
By the time you read this, the Hubble's eagle eye will have sent us thousands and thousands of wonderful pictures.

望远镜在太空中具有怎样的特殊重要性?
哈勃望远镜于1990年4月20日由美国国家航空航天局(NASA)发射升空,耗资超过10亿美元。
这艘航天器是由美国国家航空航天局(NASA)于1990年4月20日发射的,耗资超过10亿美元。
从一开始,哈勃望远镜就麻烦不断。
它发给我们的照片非常令人失望,因为它的主镜有问题(即主镜无法正常工作)。
NASA现在将着手修复这台望远镜。
因此,他们很快就会派遣四名宇航员去修理它。
“奋进号”航天飞机将把宇航员送往哈勃望远镜。
“奋进号”的机械臂会抓住望远镜,并在宇航员进行必要维修时将其固定。
当然,哈勃望远镜位于地球大气层之外。
因此,它很快就会向我们发送迄今为止最清晰的恒星和遥远星系的图像。
哈勃望远镜将帮助我们了解宇宙的年龄和规模。
等你读到这篇文章时,哈勃望远镜那“鹰眼”已经为我们传回了成千上万张精彩的照片。
