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
5 going to put the telescope right, so it will soon be sending up for
onauts 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 astronauts make the necessary
astronauts
repairs. Of course, the Hubble is above the earths atmosphere, so it will soon be sending us the clas.
10 pictures of the stars and distant galaxies that we have ever seen. The Hubble will tell us a great deal about
age and size of the universe. By the time you read this. the hubble's eagle eye will have sent us thousands a
thousands of wonderful pictures
