Atlantis Mission Offers One Last Lifeline to Hubble

This article is about the last maintenance mission the Hubble telescope will ever receive. The Hubble has been widely acknowledged as the defining technological instrument of our time. Continuous updates to the Hubble have made it 100 times more powerful now than it was when it was first launched in 1990. The Hubble's importance can be seen by the fact it recorded the first picture of another planet orbiting a star, giving credence to the theory of life on other planets. The astronaut crew will be replacing many of the different cameras and lenses on the Hubble and the mission is widely seen as being the most challenging Hubble mission, yet. The astronauts have only this one chance to repair the Hubble.
