Hubble Archive - Servicing Mission 4, STS-125

Hubble's fifth and final servicing mission, Servicing Mission 4, launched on May 11, 2009 on Space Shuttle Atlantis as part of the STS-125 mission.

During SM4, two new scientific instruments were installed – the Cosmic Origins Spectrograph (COS) and Wide Field Camera 3 (WFC3). Two failed instruments, the Space Telescope Imaging Spectrograph (STIS) and the Advanced Camera for Surveys (ACS), were brought back to life by the first ever on-orbit repairs. With these efforts, Hubble has been brought to the apex of its scientific capabilities. To prolong Hubble's life, new batteries, new gyroscopes, a new science computer, a refurbished fine guidance sensor and new insulation on three electronics bays were also installed over the 12-day mission with five spacewalks.
