--- First listen and then answer the question. |
| [00:12.640] |
--- What is the special importance of a telescope in space? |
| [00:20.240] |
The Hubble telescope was launched into space by NASA on April 20,1990 at a cost of over a billion dollars. |
| [00:33.720] |
Right from the start there was trouble with the Hubble. |
| [00:38.480] |
The pictures it sent us were very disappointing because its main mirror was faulty! |
| [00:46.360] |
NASA is now going to put the telescope right, so it will soon be sending up four astronauts to repair it. |
| [00:55.720] |
The shuttle Endeavour will be taking the astronauts to the Hubble.^“ |
| [01:01.600] |
A robot-arm from the Endeavour will grab the telescope and hold it while the astronauts make the necessary repairs. |
| [01:11.880] |
Of course, the Hubble is above the earth's atmosphere, |
| [01:17.520] |
so it will soon be sending us the clearest pictures of the stars and distant galaxies that we have ever seen. |
| [01:26.680] |
The Hubble will tell us a great deal about the age and size of the universe. |
| [01:33.560] |
By the time you read this, the Hubble's eagle eye will have sent us thousands and thousands of wonderful pictures. |
