默写新二第六十一课 lesson 61 trouble with the Hubble
|
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 will grab the telescope and hold it while the astronauts make the necessary repairs. Of course, however, the Hubble is over the earth's atmosphere. It will be sending us the clearest pictures of 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 it, the Hubble's eagle eye will have sent us thousands and thousands of wonderful pictures.
