STS-125, or HST-SM4 (Hubble Space Telescope Servicing Mission 4), was the fifth and final space shuttle servicing mission to the Hubble Space Telescope (HST). Launch occurred on May 11, 2009 at 2:01 p.m. EDT. Landing occurred on May 24 at 11:39 a.m. EDT, with the mission lasting a total of just under 13 days.
Space Shuttle Atlantis carried two new instruments to the Hubble Space Telescope, the Cosmic Origins Spectrograph and the Wide Field Camera 3. The mission also replaced a Fine Guidance Sensor, six new gyroscopes, and two battery unit modules to allow the telescope to continue to function at least through 2014. The crew also installed new thermal blanket insulating panels to provide improved thermal protection, and a soft-capture mechanism that would aid in the safe de-orbiting of the telescope by an unmanned spacecraft at the end of its operational lifespan. The mission also carried an IMAX camera and the crew documented the progress of the mission for an upcoming IMAX movie.
