Hubble Space Telescope (HST) in Earth orbit. Image taken from space shuttle Atlantis during mission STS125, the fifth and final servicing mission to the HST. Two new instruments were added to the telescope, the Cosmic Origins Spectrograph and the Wide Field Camera 3. Maintenance performed during the mission, including the addition of new insulation and replacing gyroscopes, will allow the telescope to function until at least 2014. Photograph taken on 19 May 2009, flight day 9 of the mission.
