Lesson 61. 第61课

Trouble with the Hubble. 哈勃望远镜的麻烦

The Hubble telescope was launched into space by NASA on April 20, 哈勃望远镜是NASA在1990年4月20日发射到太空的，

1990, 花了超过十亿美元。

at a cost of over a billion dollars. 从一开始，哈勃就有问题。

Right from the start there was trouble with the Hubble. 它传回的照片让人大失所望，因为主镜片有毛病。

The pictures it sent us were very disappointing because its main mirror was faulty. NASA现在打算修好这个望远镜，

NASA is now going to put the telescope right, 所以很快会派四名宇航员上去修。

so it will soon be sending up four astronauts to repair it. 奋进号航天飞机将把宇航员送到哈勃那里。

The shuttle Endeavour will be taking the astronauts to the Hubble. 奋进号的机械臂会抓住望远镜，

A robot arm from the Endeavour will grab the telescope 固定住它，好让宇航员进行必要的修理。

and hold it while the astronauts make the necessary repairs. 当然啦，

Of course, 哈勃在地球大气层之外，

the Hubble is above the Earth's atmosphere, 所以它很快会给我们传来有史以来最清晰的

so it will soon be sending us the clearest pictures 恒星和遥远星系的照片。

of the stars and distant galaxies that we have ever seen. 哈勃会告诉我们很多关于宇宙年龄和大小的事。

The Hubble will tell us a great deal about the age and size of the universe. 等你读到这篇文章的时候，

By the time you read this, 哈勃的鹰眼应该已经传回了成千上万张精彩的照片了。

the Hubble's eagle eye will have sent us thousands and thousands of wonderful pictures. 哈勃的鹰眼已经给我们发来了成千上万张精彩的照片。
