[00:10.59]What is the special importance of a telescope in space? [00:17.11]The Hubble telescope was launched into [00:19.66]space by NASA on April 20, 1990 at a cost of over a billion dollars. [00:28.68]Right from the start there was trouble with the Hubble. [00:33.84]The pictures it sent us were very disappointing because its main mirror was faulty! [00:41.31]NASA is now going to put the telescope right, [00:45.34]so it will soon be sending up four astronauts to repair it. [00:51.20]The shuttle Endeavour will be taking the astronauts to the Hubble. [00:56.33]A robot-arm from the Endeavour will grab the telescope and hold it while the astronauts make the necessary repairs. [01:06.35]Of course, the Hubble is above the earth's atmosphere, [01:11.24]so it will soon be sending us the clearest pictures of the stars and distant galaxies that we have ever seen. [01:20.73]The Hubble will tell us a great deal about the age and size of the universe. [01:27.74]By the time you read this, the Hubble's eagle eye will have sent us thousands and thousands of wonderful pictures. 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。它传送给我们的图像很令人失望，因为它的主要镜子有误差。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。“奋进”号航天飞机将把宇航员送上哈勃。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。当然，哈勃位于地球的大气层之外，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。哈勃将告诉我们有关宇宙的年龄和大小的许多事情。等到你读到这篇文章时，敏锐的哈勃望远镜已经为我们送来了成千上万张精彩的照片。
