NASA is now going to put the telescope right, so it will soon be sending up four astronauts to repair it.NASA现在将着手修复这台望远镜。因此，他们很快就会派遣四名宇航员去修理它。
The shuttle Endeavour will be taking the astronauts to the Hubble.“奋进号”航天飞机将把宇航员送往哈勃望远镜。
A robot-arm from the Endeavour will grab the telescope and hold it while the astronauts make the necessary repairs.“奋进号”的机械臂会抓住望远镜，并在宇航员进行必要维修时将其固定。
Of course, the Hubble is above the earth's atmosphere, so it will soon be sending us the clearest pictures of the stars and distant galaxies that we have ever seen.当然，哈勃望远镜位于地球大气层之外。因此，它很快就会向我们发送迄今为止最清晰的恒星和遥远星系的图像。
The Hubble will tell us a great deal about the age and size of the universe.哈勃望远镜将帮助我们了解宇宙的年龄和规模。
By the time you read this, the Hubble's eagle eye will have sent us thousands and thousands of wonderful pictures.等你读到这篇文章时，哈勃望远镜那“鹰眼”已经为我们传回了成千上万张精彩的照片。
