Lesson 61 Trouble with the Hubble 哈勃望远镜的困境Read the text and then answer the question.读课文，然后回答以下问题。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 astronau ts 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 h ave 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 Rubble's eagle eye will have sent us thousands and thousands of wonderful pictures.
