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.

STS-109 (SM3B) was a Space Shuttle mission that launched from the Kennedy Space Center on 1 March 2002. It was the 108th mission of the Space Shuttle program, the 27th flight of the orbiter Columbia and the fourth servicing of the Hubble Space Telescope. It was also the last successful mission of the orbiter Columbia before the ill-fated STS-107 mission, which culminated in the Columbia disaster.
The Hubble Space Telescope (HST) was placed in orbit during mission STS-31 on 25 April 1990. Initially designed to operate for 15 years, plans for periodic service and refurbishment were incorporated into its mission from the start.[4] After the successful completion of the second planned service mission (SM2) by the crew of STS-82 in February 1997, three of HST's six gyroscopes failed. NASA decided to split the third planned service mission into two parts, SM3A and SM3B. A fifth and final servicing mission, STS-125 (SM4) launched 11 May 2009. The work performed during SM4 is expected to keep HST in operation through 2014.

This version of the STS-109 patch has slightly different details than the A-B Emblem version. The sun has white thread.
