| "Hubble is back in action," declared Dr Heidi Hammel, a senior research scientist at the Space Telescope Science Institute in Baltimore, Maryland, from where Hubble's mission is overseen. | |
| "Together, Nasa and Hubble are opening new vistas on the Universe," she told a reporters. | |

| "Refurbishment missions are always a little bit iffy because things can go wrong; astronauts can muck it up, maybe we didn't think about this or that when we redesigned the equipment, reinstalled it and refurbished it. | "Refurbishment missions are always a little bit iffy because things can go wrong; astronauts can muck it up, maybe we didn't think about this or that when we redesigned the equipment, reinstalled it and refurbished it. |

| The Atlantis astronauts conducted five spacewalks, to install new instruments and thermal blankets, to repair two existing instruments, and replace the telescope's gyroscopes and batteries. | The Atlantis astronauts conducted five spacewalks, to install new instruments and thermal blankets, to repair two existing instruments, and replace the telescope's gyroscopes and batteries. |

| A key addition was the new Wide Field Camera 3. This is the instrument that many astronomers suspect will deliver the really big discoveries in the remaining operational years. | A key addition was the new Wide Field Camera 3.

| One of the simpler tasks undertaken during the repair mission was to fit a docking ring that will serve as a point of contact with the defunct Hubble sometime after 2020. | One of the simpler tasks undertaken during the repair mission was to fit a docking ring that will serve as a point of contact with the defunct Hubble sometime after 2020. |

| "What Hubble has done: it's enabled our hearts, our minds, our spirits to travel throughout the Solar System, even billions of light-years to the very beginning of time almost. And I think its ability to inspire at least some of our school kids to consider careers in engineering, science and math - that will be its most important legacy, not just keeping us astronomers happy." | "What Hubble has done: it's enabled our hearts, our minds, our spirits to travel throughout the Solar System, even billions of light-years to the very beginning of time almost.
