STS 134



STS 134 was launched from Cape Canaveral on 16 May 2011 at 12:56 UT. Shuttle Endeavour docked with the International Space Station's (ISS) Harmony module on 18 May 2011 at 10:14 UT. The craft carried a crew of six for a 16-day mission. STS 134 was the 134th shuttle flight, the 25th and final flight for Endeavour and the 36th shuttle mission dedicated to station assembly and maintenance. The shuttle delivered the Alpha Magnetic Spectrometer (AMS), a particle physics detector designed to operate from the station and search for various types of unusual matter. Also on-board for delivery were station spare parts on the ExPRESS Logistics Carrier 3 (ELC3), including two S-band communications antennas, a high-pressure gas tank, an ammonia tank assembly, circuit breaker boxes, a Canadarm2 computer and a spare arm for the Dextre robot. The ELC3 also houses a suite of Department of Defense (DoD) experiments that will test systems and materials concepts for long duration spaceflight in low-earth orbit. STS 134 mission included four spacewalks that focused on station maintenance, experiment replacement, and transference of Endeavour's orbiter boom sensor system (OBSS) to the station. The crew left the boom as a permanent fixture to aid future station spacewalk work, if needed. The mission also featured Endeavour's approach back toward the station after undocking to test new sensor technologies that could make it easier for future space vehicles to dock to the ISS. STS 134 completed its mission with a landing at Cape Canaveral on 01 June 2011 at 06:35 UT. STS 134 was the second-to-last flight for the Space Shuttle Program.
