sts-125

STS-400 was the Space Shuttle contingency support (Launch On Need) flight which would have been launched using Space Shuttle Endeavour if a major problem occurred on Space Shuttle Atlantis during STS-125, the final Hubble Space Telescope servicing mission (HST SM-4).
Due to the much lower orbital inclination of the HST compared to the ISS, the shuttle crew would have been unable to use the International Space Station as a "safe haven" and NASA would not have been able to follow the usual plan of recovering the crew with another shuttle at a later date. Instead, NASA developed a plan to conduct a shuttle-to-shuttle rescue mission, similar to proposed rescue missions for pre-ISS flights. The rescue mission would have been launched only three days after call up and as early as seven days after the launch of STS-125 since the crew of Atlantis would only have about three weeks of consumables after launch.

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 11 May 2009 at 2:01 pm EDT.  Landing occurred on 24 May at 11:39 am 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 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.

This version has a thinner border around the solar panels of the HST and black for the panels themselves.

This version of the patch was the as-flown version. There was also a prototype version that was visible on crew suits during training for the mission and can be identified by the dotted stitching style around the solar panals of the HST. Thhis version has thicker, solid embroidery around the solar panels.
