Lesson61 Trouble with the Hubble
The Hubble telescope was launched into space by NASA on April 20,1990 at a cost of over a billiondollars. Right from the start there was trouble with the Hubble. The picturesit 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 fourastronauts to repair it. The shuttle Endeavour will be taking the astronauts tothe 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 ofthe stars and distant galaxies that we have ever seen. The Hubble will tell usa 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.
