STS-134 (ISS assembly flight ULF6)[9] was the penultimate mission of NASA's Space Shuttle program and the 25th and last spaceflight of Space Shuttle Endeavour.[10] This flight delivered the Alpha Magnetic Spectrometer and an ExPRESS Logistics Carrier to the International Space Station.[11] Mark Kelly served as the mission commander. STS-134 was expected to be the final Space Shuttle mission if STS-135 did not receive funding from Congress. However, in February 2011, NASA stated that STS-135 would fly "regardless" of the funding situation.[12][13] STS-135, flown by Atlantis, took advantage of the processing for STS-335, the Launch on Need mission that would have been necessary if the STS-134 crew became stranded in orbit.
Changes in the design of the main payload, AMS-02, as well as delays to STS-133, led to delays in the mission. The first launch attempt on April 29, 2011, was scrubbed at 12:20 pm by launch managers due to problems with two heaters on one of the orbiter's auxiliary power units (APU). Endeavour launched successfully at 08:56:28 EDT (12:56:28 UTC)[14] on May 16, 2011,[15] and landed for the final time on June 1, 2011.[16]
