STS 134 Endeavour Key Ring

STS-134 (ISS assembly flight ULF6) is the 134th and penultimate planned mission of the Space Shuttle Program (which began service on 12 April 1981). This flight will deliver the Alpha Magnetic Spectrometer and an ExPRESS Logistics Carrier to the International Space Station.[4] The mission will also mark the final flight of Space Shuttle Endeavour. Changes in the design of the main payload, AMS-02, as well as delays to STS-133 have led to delays in the mission, and it is now targeted to launch on 27 February 2011. STS-134's LON mission, a contingency mission to rescue a stranded STS-134 crew, would be the STS-335 flight.
