A NASA video showing the launch of STS-134, the penultimate mission of NASA's Space Shuttle program and the 25th and last spaceflight of Space Shuttle Endeavour. Led by the mission commander Mark Kelly, this flight delivered the Alpha Magnetic Spectrometer and an ExPRESS Logistics Carrier to the International Space Station. The first launch attempt, on 29 April 2011, was canceled due to problems with two heaters on one of the orbiter's auxiliary power units (APU); a second, successful attempt was made on 16 May 2011. The shuttle landed for the final time on 1 June 2011.Video: NASA
