Lesson 61 Trouble with the Hubble

一、阅读课文

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. (161 words)
