STS-134とは 意味・読み方・使い方

STS-134 (ISS assembly flight ULF6) was the second-to-the-last mission of NASA's Space Shuttle program. The mission marked the 25th and the final flight of Space Shuttle Endeavour. This flight delivered the Alpha Magnetic Spectrometer and an ExPRESS Logistics Carrier to the International Space Station. 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. The Launch On Need mission, a contingency mission to rescue a stranded STS-134 crew, would have been the STS-135 flight (formerly STS-335), flown by Atlantis.
