哈勃望远镜于1990年4月20日由国家航空航天局发射升空，耗资10多亿美元。

从最开始哈勃望远镜就有问题。
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.
国家航天局准备纠正这一错误，为此将把4名宇航员送入太空修复望远镜。
The shuttle Endeavour will be taking the astronauts to the Hubble.
“奋进”号航天飞机将把宇航员送上哈勃。
A robot-arm from the Endeavour will grab the telescope and hold it while the astronauts make the necessary repairs.
当宇航员进行必要的修复工作时，“奋进”号上的一只机器手将抓住望远镜并托住它。
Of course, the Hubble is above the earth s atmosphere,
当然，哈勃位于地球的大气层之外，
so it will soon be sending us the clearest pictures of the stars and distant galaxies that we have ever seen.
因此，它很快就会给我们传送我们所见到过的、有关行星和远距离星系的最清晰的照片。
The Hubble will tell us a great deal about the age and size of the universe.
哈勃将告诉我们有关宇宙的年龄和大小的许多事情。
By the time you read this, the Hubble s eagle eye will have sent us thousands and thousands of wonderful pictures.
