This was reported by NASA to be a critical technology, granting the instrument the high sensitivity needed to achieve mission objectives. Īccording to the original design plan, a cryogenic, superconducting magnet system was developed for the AMS-02. The AMS-02 unit is a particle physics detector which contains a large permanent magnet, and is designed to search for antimatter and investigate the origin and structure of dark matter. The Alpha Magnetic Spectrometer 2 (AMS-02) was carried to the ISS in Endeavour 's payload bay, and was attached to the ISS's S3 truss segment.

On May 16, Giffords was again at KSC for the launch, which was "one of the most anticipated in years," according to The New York Times. Representative Gabby Giffords, flew to the Kennedy Space Center (KSC) in Florida to view the first launch attempt, her first trip since moving from Tucson to Houston for rehabilitation after being seriously wounded in the January 2011 Tucson shooting. Shuttle Commander Mark Kelly's wife, U.S. If STS-134 had launched during Expedition 26, then Mark Kelly and Expedition 26 commander Scott Kelly would have become the first siblings (and twins) to fly in space at the same time. It was also originally scheduled to coincide with Expedition 26 before delays in the Space Shuttle launch schedule pushed it past that Expedition. STS-134 was planned to be the final regularly scheduled mission of the NASA Space Shuttle Program, but with the passing in 2011 of an appropriations bill authorizing the conversion of STS-335 to STS-135, this was no longer the case. In the spring of 2009, the Obama Administration included funds for the STS-134 mission in its proposed 2010 NASA budget. Bush had previously opposed any additional shuttle missions, as they could delay the transition to Project Constellation. It was amended and passed by the full Senate on September 25, 2008, passed by the House on September 27, 2008, and signed by President George W. Senate version of the NASA Authorization Act that was unanimously approved by the Senate Committee on Commerce, Science, and Transportation on June 25, 2008.
The same mandate was included in the U.S. On June 19, 2008, the United States House of Representatives passed the NASA Authorization Act of 2008, giving NASA funding for one additional mission to "deliver science experiments to the station". The Space Shuttle had been scheduled to be retired from service after STS-133, but controversy over the cancellation of several International Space Station components, most notably the Alpha Magnetic Spectrometer, in order to meet deadlines for the retirement of the shuttle, caused the United States Government to consider ordering an additional mission. astronaut to fly with the shuttle.īackground STS-134 Space Shuttle launch
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). 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.Ĭhanges in the design of the main payload, AMS-02, as well as delays to STS-133, led to delays in the mission. However, in February 2011, NASA stated that STS-135 would fly "regardless" of the funding situation. STS-134 was expected to be the final Space Shuttle mission if STS-135 did not receive funding from Congress. Mark Kelly served as the mission commander. This flight delivered the Alpha Magnetic Spectrometer and an ExPRESS Logistics Carrier to the International Space Station. STS-134 ( ISS assembly flight ULF6) was the penultimate mission of NASA's Space Shuttle program and the 25th and last spaceflight of Space Shuttle Endeavour.
