Trouble with the Hubble 哈勃望远镜的困境 TheHubble telescope was launched into space by NASA on April 20，1990 at a cost of over a billion dollars. Right from the start therewas trouble with the Hubble. The pictures it sent us were very disappointingbecause its main mirror was faulty! NASA is now goingto put the telescope right， so it will soon be sendingup four astronauts to repair it. The shuttle Endeavour will be taking theastronauts to the Hubble. A robot-arm from the Endeavour will grab thetelescope and hold it while the astronauts make the necessary repairs. Ofcourse， the Hubble is above the earth s atmosphere， so it will soon be sending us the clearest pictures of the starsand distant galaxies that we have ever seen. The Hubble will tell us a greatdeal 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 ofwonderful pictures.
