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
s going to put the telescope right, so it will soon be sending up four
ts to repair it. The shuttle Ende
ur will be taking th
astronauts to the Hubble. A robot-arm from the Endeavour will grab
the telescope and hold it while the astronauts make the necessar,
asironallis
repairs. Of course, the Hubble is above the earth's atmosphere, so it will soon be sending us the cln
10 pictures of the stars and distant galaxies that we have ever seen. The Hubble will tell us a great deal abl
age and size of the universe. By the time you read this, the ftubble's eagle eye will have sent us housui
thousands of wonderful picture
