 The completion of all the major objectives, as well as some that were not considered vital, upgraded the Hubble telescope to its most technologically advanced state since its launch nineteen years before and made it more powerful.The upgrades helped Hubble to see deeper into the universe and farther into the past, closer to the time of the Big Bang.STS-125 was the only visit to the Hubble Space Telescope for "Atlantis"; the telescope had been previously serviced twice by "Discovery" and once each by "Columbia" and "Endeavour".
